Geographical indication of coffee in Brazil: identification and effects of the critical success factors towards sustainability

The Geographical Indication (GI) is more than just a mechanism for protecting farmers. This mechanism, materialized by a sign of geographical identity, determines differentiation and added value in a complex process that requires an intense effort of governance and cooperativism. The aim of this study was to analyze the critical success factors for increasing competitiveness and sustainability in the process of geographical identification for certified coffee producers in the Espírito Santo do Pinhal region of Brazil. Factors such as market arrangements, production techniques, quality differentiation, price formation, cost structure, organization and articulation around the construction and maintenance of the market by producers in this region were analyzed. The proposed methodology used an analytical framework of the certification of origin market that correlates market practices with production arrangements in a longitudinal process, considering their challenges and impacts. The results indicate that critical success factors (CSFs) identified in the certification of GIs for coffee producers are related to strong cooperative and associative actions and the presence of entities that coordinate the acquisition process and establish the rules and obligations of those involved, always aiming to encourage investment in technology and technification in pursuit of efficiency and the quality of the final product. In addition, strict control of the production method, avoiding the use of production techniques that harm the environment with good coffee-growing practices, contributes to obtaining and maintaining the GI as well as to develop appropriate attributes of sustainability.

The formation of a sustainable organizational identity: Insights from Brazilian coffee producers

AbstractOrganizations craft their identities to define their character and effectively communicate their values to stakeholders. In the contemporary quest for sustainability, building an identity that genuinely reflects their awareness and attention to these issues is increasingly salient. Over the years, research on organizational identity exhibited constant growth, witnessing the power of organizational identities exerted over organizational behavior. Prior research has emphasized the importance of organizational identity for an array of positive organizational outcomes. Still, much less is known about the levers behind the identity formation process. Against this backdrop, the present study explores the pathways to the formation of a sustainable organizational identity. By drawing on organizational identity and sensemaking literature, we build up a narrative inquiry, analyzing the experiences and perspectives of executives from 25 Brazilian coffee producers through in‐depth interviews. The findings underline that the process of formation involves three phases, namely, orienting toward sustainability, acting sustainably, and forging a sustainable identity, which are also shaped by contextual factors. We emphasize the key role of leadership in building a sustainable identity, as their motivations and sustainability‐oriented commitments could serve as catalysts for triggering organizational change.

Future climate suitability of Hemileia vastatrix in arabica coffee under CMIP6 scenarios.

Coffee (Coffea arabica L.) is one of the most important commodities today, with a high economic value worldwide. Coffee leaf rust (Hemileia vastatrix Berk. et Br.) has been showing a high impact on Brazilian coffee trees among the various diseases that attack coffee. The climate has a great influence on the development of diseases, especially when fungi are the causal agents. This study aimed to carry out the zoning of climate favorability for coffee leaf rust in the traditional and main coffee-producing regions of Brazil. The study was conducted in 13 locations in the states of Paraná, São Paulo, Rio de Janeiro, Espírito Santo, Minas Gerais, Goiás and Bahia. Air temperature and daily precipitation data for the current scenario were collected using the WorldClim version 2.1 platform for the last climatological normal and future climate change data. The ideal climate conditions for coffee leaf rust consist of a mean air temperature ranging from 21 to 25 °C and precipitation >30 mm per month. The Coupled Model Intercomparison Projects scenarios associated with the Intergovernmental Panel on Climate Change reports consisted of the Shared Socio-Economic Pathways SSP-1 2.6, SSP-2 4.5, SSP-3 7.0 and SSP-5 8.5, the latter being considered one of the most catastrophic. All steps to carry out the suitability zoning were performed in a tool using the QGIS geographic information system software. Zoning for coffee leaf rust had three classes: favorable, relatively favorable and unfavorable. Currently, the largest coffee-producing region in Brazil has 49.1% of its analyzed area classified as favorable, 39.2% as relatively favorable and 11.7% as unfavorable. In the current scenario, Patrocínio and Três Pontas are locations with high coffee production in which the favorable class is predominant. The state of Minas Gerais has an annual mean of 55.3% of its entire territory apt for the disease, with the highest occurrence between September and March. Climate change has a negative impact on the development of coffee leaf rust, mainly in the long term, as in the period of 2081-2100, in which the SSP-5 8.5 scenario led to a decrease in the favorable and unfavorable areas and an increase in the relatively favorable areas of 9.8%, 18.6% and 71.5% for the Brazilian territory, respectively. © 2024 Society of Chemical Industry.

The construction of brand positioning: an exploratory study on Nescafé Origens do Brasil

The article is a study on the positioning of the Nescafé Origens do Brasil brand, built with a focus on the place of origin of the inputs used in its products. We sought to discuss the marketing strategies adopted by the brand, Nestlé's sustainability flagship in Brazil, and the behavior of the Brazilian coffee consumer. The research is qualitative in nature and has a methodological procedure that involves bibliographical research on marketing, with a theoretical approach to brand positioning. Martin-Barbero's (2001) concept of mediations is also adopted to explore the communication process present in the advertising film “The Carbon Neutral Journey”, by Nescafé Origens do Brasil. The aim is to understand how the variables of the brand's communication dynamics contribute to the construction of its strategic positioning. As a result, it was identified that the mechanisms adopted by the brand contributed to (I) the construction of a strategic positioning based on sustainable development, (II) overvaluing the products; (III) create a competitive advantage; (IV) feed it back based on information from consumers, who begin to give new meaning to the choice of coffee they consume.

Host status of cover crops for the management of Meloidogyne izalcoensis in coffee orchards infested with root-knot nematodes

Summary The root-knot nematode Meloidogyne izalcoensis was described parasitising coffee trees and causing damage in the Izalco volcano region, Sonsonate, El Salvador. In Brazil, it was detected in coffee roots in the municipality of Indianópolis, Minas Gerais state (MG). Intercropping cover crops is a traditional practice in Brazilian coffee orchards, and the use of plants that are non-hosts or antagonistic to the nematodes is a very promising strategy for coffee in infested areas. Due to the scarce information on the host status of M. izalcoensis, the aim of this study was to evaluate 24 plants of different species of cover crops and select the non-hosts or poor hosts. Two assays were conducted at different times, and all plants were inoculated with 10 000 eggs. After 90 days, the following parameters were determined: fresh root weight, reproduction factor (RF) and final reaction. Plants with RF < 1.0 were classified as non-hosts (NH), those with RF > 1.0 were classified as hosts and using statistical analyses as: good host (GH), intermediate host (IH) and poor host (PH). Most of the botanical species tested were classified as NH or PH to M. izalcoensis: cotton, rice, white oat, black oat, ryegrass, corn, three species of grass, two cultivars of millet, two wheat cultivars, Crotalaria breviflora, C. ochroleuca, C. spectabilis, jack bean, gray mucuna bean and two species of rice grass. Only tomato and bean were classified as GH, and C. juncea and soybean were classified as IH. The plants identified as non-hosts or poor hosts can be recommended for intercropping or for crop rotation in Brazilian coffee orchards in regions infested by M. izalcoensis.

Market Practices and Structuring Practices on Market Making: Sustainable Certified and Specialty Coffee Market Dynamics in Brazil

On this paper, in a five years longitudinal study, the theoretical framework the constructivist market studies (CMS) were used to analyze how market practices interacted with structuring practices in the making of market arrangements throughout the sustainable and specialty coffee market development process in Brazil. Through the historical reconstruction of the UTZ certification program in Brazil and the Cup of Excellence (COE) coffee quality competition, based on document analysis and in-depth interviews, it was possible to identify the main market practices adopted by the actors involved in the organization and in market designing. It was possible to select specific translation moments that resulted in different market framings, showing how rules, devices and practices shaped the Brazilian coffee market. Main representational, normalizing and exchange practices were identified and it was highlighted the role of a new analytical category called “market structuring practices”, which acts as an important mechanism for the making of market arrangements and for the shaping and consolidation of market practices (marketization process).

Impacts of Brazilian Green Coffee Production and Its Logistical Corridors on the International Coffee Market

Background: The coffee industry is one of the most important world supply chains, with an estimated consumption of two billion cups daily, making it the most consumed beverage worldwide. Coffee beans are primarily grown in tropical countries, with Brazil accounting for almost 50% of the production. The objective of this study is to examine the Brazilian trade between 2018 and 2022, focusing on state producers, logistical corridors, and importer countries. Methods: The methodology approach revolves around a quantitative method using Social Network Analysis measures. Results: The results reveal a massive concentration in local production (99.5%—Minas Gerais), port movements (99.9%—Santos, Itaguai, and Rio de Janeiro), and country buyers (80.9%—the United States, United Kingdon, and Japan). Conclusions: The study concludes that the Brazilian green coffee supply chain relies on a fragile and overloaded logistical network. Due to that, this study indicates that the stakeholders and decision-makers involved must consider this high concentration of production in some areas and companies. They must also address the bottlenecks in logistical corridors and the fierce competition involved in acquiring and processing Brazilian coffee production because these factors can drastically affect the revenue of the companies operating in this sector.

Unveiling the coopetition pathway: the stakeholder influence in the specialty coffee market

PurposeThis study aimed to understand coopetition in the context of Brazilian specialty coffee grower Small and medium enterprises (SMEs), based on the need to differentiate the beans in and outside the farm level, taking into account the stakeholders’ influence.Design/methodology/approachIn this study twenty semistructured interviews were carried out with coffee growers and managers of cooperatives, associations and supporting institutions involving two Brazilian coffee geographical indications. Data were analyzed using a mixed grid composed of qualitative, semantic and categorical factors.FindingsStrategic moves undertaken by coffee growers and stakeholders have shaped the pathway of coopetition among coffee growers, as determinants to frame it as a deliberate or emergent pattern (intentional or unplanned, respectively). Our findings provide evidence that coopetition development among firms is deliberate when influenced by firms’ or stakeholders’ cooperative moves and emergent when influenced by firms’ or stakeholders’ competitive moves.Originality/valueAlthough the firm/stakeholder relationship is often approached as a joint wealth creation effort, stakes are not always fairly distributed, so one of the parties may be negatively affected, with consequences for the development of coopetition. Underpinned by a stakeholder-oriented resource-based theoretical lens, this investigation of the development patterns of coopetition linked to the strategic actions undertaken by firms and stakeholders has resonance on competitive advantages.

Ammonia volatization from conventional and stabilized fertilizers, agronomic aspects and microbiological attributes in a Brazilian coffee crop system.

We aimed to quantify the N losses through volatilization of the main conventional and stabilized N fertilizers applied in coffee plantations. Additionally, we also assessed microbiological attributes of the soil (microbial biomass carbon (MBC); microbial biomass nitrogen (MBN); microbial basal respiration (MBR); metabolic quotient (qCO2); urease, β-glucosidase, acid phosphatase, and arylsulfatase activities) and agronomic aspects of the crop (N content in the leaves and beans, yield, and N exportation by the beans). Treatments consisted of the combination of three fertilizers (ammonium nitrate - AN, conventional urea - U, and urea with N- (n-butyl) thiophosphoric triamide (NBPT) - UNBPT, and five doses of N (0, 150, 275, 400, and 525kg ha-1 year-1 of N), with four replicates, totalling 60 experimental plots. In the two crop seasons evaluated, daily and cumulative losses of N-NH3 from the split fertilizer applications were influenced by the N fertilizer technologies. The application of U resulted in losses of 22.0% and 22.8% for the doses of 150 and 400kg ha-1 year-1 of N. This means that 66 and 182kg ha-1 of N-NH3 were lost, respectively, at the end of six fertilizations with U. UNBPT reduced urease activity and N-NH3 losses compared to conventional urea, avoiding the volatilization of 15.9 and 24.3kg ha-1 of N. As for AN, N-NH3 losses did not exceed 1% of the applied dose, regardless of the weather conditions during the fertilization. Urease activity was higher on days of maximum NH3 volatilization. There was an effect of the N sources (NS), soil sampling time (ST), and their interaction (NS × ST) on the MBN and arylsulfatase activity. The N sources also influenced the MBC and the qCO2. A substantial amount of N was removed from the system by the beans and husks of the harvested fruits. Our study showed that N fertilizer technologies are interesting options to reduce N-NH3 losses by volatilization, increase N retention in the soil, and improve microbiological attributes and the sustainability of coffee production systems.

HS-SPME-GC-MS combined with metabolomic approach to discriminate volatile compounds of Brazilian coffee from different geographic origins

Coffee, primarily the Coffea arabica variety, is a significant agricultural product in Brazil, well-known for its flavor, which is intimately tied to its chemical composition. In this study, we assessed the volatile compounds found in arabica coffee beans from various Brazilian regions using headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry (HS-SPME-GC-MS). Mass spectra from these volatile compounds were cross-referenced with the NIST and WILEY libraries. Furthermore, the data obtained through GC-MS analysis were subjected to a metabolomics approach utilizing the MS-DIAL software. Principal component analysis (PCA) categorized the samples into three distinct groups, while Partial Least Squares (PLS) identified the volatile compounds responsible for the similarities and differences among these groups. Our findings revealed variations in the composition of volatile compounds based on the coffee's origin. Additionally, the results demonstrated that altitude plays a significant role in aroma composition, with higher altitudes associated with a more diverse and remarkable aroma, whereas lower altitudes were linked to a lower aroma quality.

Pseudomonas syringae coffee blight is associated with the horizontal transfer of plasmid-encoded type III effectors.

The emergence of new pathogens is an ongoing threat to human health and agriculture. While zoonotic spillovers received considerable attention, the emergence of crop diseases is less well studied. Here, we identify genomic factors associated with the emergence of Pseudomonas syringae bacterial blight of coffee. Fifty-three P. syringae strains from diseased Brazilian coffee plants were sequenced. Comparative and evolutionary analyses were used to identify loci associated with coffee blight. Growth and symptomology assays were performed to validate the findings. Coffee isolates clustered in three lineages, including primary phylogroups PG3 and PG4, and secondary phylogroup PG11. Genome-wide association study of the primary PG strains identified 37 loci, including five effectors, most of which were encoded on a plasmid unique to the PG3 and PG4 coffee strains. Evolutionary analyses support the emergence of coffee blight in PG4 when the coffee-associated plasmid and associated effectors derived from a divergent plasmid carried by strains associated with other hosts. This plasmid was only recently transferred into PG3. Natural diversity and CRISPR-Cas9 plasmid curing were used to show that strains with the coffee-associated plasmid grow to higher densities and cause more severe disease symptoms in coffee. This work identifies possible evolutionary mechanisms underlying the emergence of a new lineage of coffee pathogens.

Microbiomes associated with Coffea arabica and Coffea canephora in four different floristic domains of Brazil

Brazilian coffee production relies on the cultivation of Coffea arabica and Coffea canephora. Climate change has been responsible for the decreasing yield of the crops in the country yet the associated microbial community can mitigate these effects by improving plant growth and defense. Although some studies have tried to describe the microorganisms associated with these Coffea species, a study that compares the microbiome on a wider spatial scale is needed for a better understanding of the terroir of each coffee planting region. Therefore, our aim was to evaluate the microbial communities harbored in soils and fruits of these Coffea species in four Brazilian floristic domains (Amazon, Atlantic Forest Caatinga, and Cerrado). One hundred and eight samples (90 of soil and 90 of fruits) were used in the extraction and sequencing of the fungal and bacterial DNA. We detected more than 1000 and 500 bacterial and fungal genera, respectively. Some soil microbial taxa were more closely related to one coffee species than the other species. Bacillus bataviensis tends to occur more in arid soils from the Caatinga, while the fungus Saitozyma sp. was more related to soils cultivated with C. arabica. Thus, the species and the planting region (floristic domain) of coffee affect the microbial composition associated with this crop. This study is the first to report microbial communities associated with coffee produced in four floristic domains that include sites in eight Brazilian states. Data generated by DNA sequencing provides new insights into microbial roles and their potential for the developing more sustainable coffee management, such as the production of biofertilizers and starter culture for fermentation of coffee cherries.

Climate risks and vulnerabilities of the Arabica coffee in Brazil under current and future climates considering new CMIP6 models

The susceptibility to climate change concerns the coffee market worldwide due to possible severe productivity losses. Brazil is the world's largest Arabica coffee producer and has crops in regions considered persistent climate change hotspots. Our study analyzed risks, vulnerabilities, and susceptibilities to pests and diseases in these regions under current and future climates and outlined adaptive measures to reduce future vulnerabilities. Ten risk indicators based on Arabica coffee requirements were proposed: water supply (Iw), base (TIB) and maximum temperature stresses (TImax), which delimit the temperature range where Arabica coffee grows and productivity is penalized outside both ranges, frost stress (TIfrost), diseases such as rust (DIrust), brown eye spot (DIbrown), and Phoma leaf spot (DIphoma), pests such as coffee berry borer (PIberry), coffee leaf miner (PIminer), and yield loss due to water stress (Iyg). Daily near-surface air temperature (minimum, mean, and maximum), relative humidity, precipitation, and global solar radiation were used from 16 General Circulation Models (GCMs) from the NASA Earth Exchange Global Daily Downscaled Projections (NEX-GDDP), which are derived from the Coupled Model Intercomparison Project Phase 6 (CMIP6) in three Shared Socioeconomic Pathways scenarios (SSP245, SSP370 and SSP585). All risk indicators were calculated for the current climate (1995–2014) and projected for the near (2041–2060), intermediate (2061–2080), and far future (2081–2100) in three SSPs and then classified into five risk classes (very low, low, moderate, high and very high). Our results indicated that due to increases in TImax and Iyg indicators, with high to very high risk in area and magnitude, Arabica coffee plantations will be negatively affected and economically unfeasible for about 35 % to 75 % of the studied area throughout the 21st century. Furthermore, the rust and the leaf miner will remain a concern in future climates due to increased temperatures and reduced relative humidity. The future of Arabica coffee crops in Brazil will depend on adopting effective adaptive measures and prudent agricultural strategies to address anticipated risks, including shifting crops to higher altitude areas, introducing more climate-resilient coffee cultivars/varieties, using agroforestry or intercropping systems, planting in closer spacing or higher density planting, and employing dripper or partial root-zone irrigation techniques.

Comparison between enzymatic and molecular diagnostic techniques for identification of Meloidogyne spp. on coffee in Brazil and restricted occurrence of M. izalcoensis

Root-knot nematodes (RKNs), Meloidogyne spp. are considered important pathogens of the coffee crop, limiting production and causing economic losses. Meloidogyne izalcoensis was recently detected in the Triângulo Mineiro region, Minas Gerais (MG) state of Brazil, parasitizing coffee plants. To investigate the distribution of this particular nematode species in this region, two small prospective surveys targeting Meloidogyne spp. on coffee plantations were carried out, employing two different techniques (esterase phenotypes (Est) and SCAR markers) in the municipalities of Araguari and Indianópolis where M. izalcoensis had been previously detected. Unfortunately, the high level of female degeneration in the second survey prevented us from identifying the species using esterase phenotypes. In both surveys, we employed the SCAR-coffee Kit, which proved to be highly effective in accurately identifying all the species of Meloidogyne found in coffee plants especially M. exigua. By using eggs and second stage juveniles (J2s) extracted from coffee roots, we obtained reliable markers for the identification of M. exigua (41.67%), M. incognita (33.33%), M. paranaensis (20.83%) and M. izalcoensis (4.17%), which can be used as unique tools in multiplex in the characterization of Meloidogyne spp. from coffee. Mixed population species were also observed in 20.83% of the samples. The use of SCAR markers proved to be the most effective tool for accurately identifying M. exigua and mixed species. These surveys confirmed that M. izalcoensis has a restricted occurrence in the region where it was initially detected.

Mild Arabica coffee trade at a time of market regulation

ABSTRACT This paper explores the dynamics of mild coffee trade during the term of the International Coffee Agreement, focusing on Costa Rica as a case study. We aimed to verify the influence of the agreement on coffee exports and understand its impact on the exports of high-quality coffee. To compare the influence of the coffee agreement on the trade performance of high-quality coffee producers with that of producers specializing in coffee of similar – or lower – quality, we also included exports of Brazilian coffee (low quality) and Colombian coffee (high quality) in the sample. We focused on analysing commodity trade agreements in the second half of the twentieth century and, simultaneously, on the drivers of coffee exports based on a gravity equation consistent with international trade models. Our findings allowed us to conclude that the International Coffee Agreement gave rise to few benefits for ‘Other Milds’ countries such as Costa Rica and greater benefits for ‘Colombian Milds’ countries such as Colombia, at least in its early versions.

Using the Life Cycle Approach for Multiobjective Optimization in the Context of the Green Supply Chain: A Case Study of Brazilian Coffee

This study proposes a multiobjective optimization model (MOO) based on a green supply chain so that coffee produced in Brazil could supply the North American market with lower environmental impacts and costs. Production and distribution arrangements were established considering four coffee-producing regions, three ports of origin in Brazil, four destination ports, seven roasting plants, and fifteen consumption centers, all distributed throughout the American territory. Environmental and economic performances regarding global warming potential (GWP) and costs were determined for a life cycle approach. The results indicate that coffee cultivation has the most significant contributions to the GWP of the arrangements. The transport of the product by road also plays an essential role, especially if extensive distances are covered during the port–roaster–consumer center journey in the United States. The analysis showed differences of 2.0 kg CO2eq and US$8.00 per ton of coffee between the best and worst arrangements, which can be considered significant when projected to the Brazilian annual coffee export scale. In the environmental limit condition, the optimization can lead to non-trivial results compared to the real market. The model conceived for the MOO can be improved to reproduce more realistic conditions by incorporating producer and consumer markets, inserting uncertainties.

Newly isolated phages preying on Pseudomonas syringae pv. garcae: In vitro and ex vivo inactivation studies in coffee plant leafs

Coffee canker, or bacterial halo blight (BHB) of coffee, is a disease caused by the phytopathogenic bacterium Pseudomonas syringae pv. garcae (Psg), having been found for the first time in 1955, in the Garça region (State of São Paulo), and which has stood out in the Brazilian coffee plantations in recent years, leading to severe economic losses that seriously affect coffee trade. The treatments available are still scarce, involving frequent spraying of coffee plantations with either copper derivatives or the antibiotic kasugamycin. However, these compounds should be avoided due to environmental toxicity and the development of bacterial resistances. Herein we report the isolation and physical/biological characterisation of two novel lytic phages and their efficacy in the control of Psg. Phages ph002F and ph004F were isolated from coffee plant leaves in Brazil (Sorocaba/SP and Itu/SP cities), using Psg IBSBF-158 as the host. According to the transmission electron microscopy analyses, both phages belong to the class Caudoviricetes and present myovirus-like morphotypes. Phages ph002F and ph004F showed eclipse times of 5 min and 20 min, respectively, and a burst size of 123 PFU/host cell and 12 PFU/host cell, respectively, allowing to conclude they replicate well in Psg IBSBF-158 with latency periods of 50 min. Phage ph002F (reduction of 4.59 log CFU/mL, compared to uninfected culture) was more effective in inactivating Psg than phage ph004F (reduction of 3.85 log CFU/mL) after 10 h of incubation at a MOI of 10. As a cocktail, the two phages were highly effective in reducing the bacterial load (reduction of 5.26 log CFU/mL at a MOI of 0.1 or reduction of 5.03 log CFU/mL at a MOI of 10, relative to untreated culture), after 12 h of treatment. This study provides evidence that the isolated phages are promising candidates against the causative agent of BHB in coffee plants.

First record of occurrence and injury of Anomala testaceipennis Blanchard, 1851 (Coleoptera: Scarabaeidae: Rutelinae) in arabica coffee in Brazil

The objective of this study is to record the injury of Anomala testaceipennis Blanchard, 1851 (Coleoptera: Scarabaeidae: Rutelinae) adults in coffee Coffea arabica L. in municipality of Piumhi, Minas Gerais, Brazil. This is the first reported of the A. testaceipennis attacking coffee.

Nitrogen fertilizers technologies as a smart strategy to mitigate nitrous oxide emissions and preserve carbon and nitrogen soil stocks in a coffee crop system

The paper consolidates the role of conventional and stabilized N fertilizers used in coffee crop production in Brazil and their N2O emissions in tropical systems. The experiment consisted of the combination of three fertilizers and five doses with four repetitions, totalling 60 experimental plots. The factors of the experiment were conventional urea (U), ammonium nitrate (AN), and urea + NBPT (UNBPT), while the doses were 0, 150, 275, 400, and 525 kg ha−1 year−1 of N. The municipality is located in a region at 1100 m of altitude, 20°53′26.04″ S and 44°52′04.14″ W. A randomized block design with a 3 × 5 factorial scheme was used. This region, traditional in coffee production, has a tropical humid climate, classified as Cwa according to the Köppen scale, with temperate summer and dry winter. UNBPT and the ammonium nitrate mitigated the N2O emissions by 50.6% and 78.5%, respectively, in comparison to the conventional urea. High C stocks were found in the 1 m soil layer, from 117 to 162 t ha−1 of organic C, indicating the importance of the soil as a C sink in coffee plantations. N stocks varied from 33 to 17 t ha−1 of N but no differences among the treatments were found. Approximately 50% of soil C was in the 0–0.4 m layer as a consequence of the greater amount of plant biomass, nutrients, and biological activity. Soil C:N ratio in the entire layer varied from 4.2 to 9.2. Our results indicate that nitrification is the most predominant process of N2O emissions. The standard EF proposed by the IPCC overestimates the N2O emissions in the Brazilian coffee plantations and the emissions differ according to the N fertilizer technology. These coffee crop systems have an important ability to stock C and N in the soil.
