Deep return of straw improves topsoil health and maize productivity more efficiently than shallow return

AbstractStraw return is an important nature‐based solution to identify optimal management practices to maintain cropland soil health and food security. However, there is still limited information available regarding the impacts of different straw return strategies on soil health, especially when considering a comprehensive assessment of soil physical, chemical and biological characteristics. Soil microorganisms are the core and key to maintaining soil health. The present research aims to determine the impact of straw return to different depths on soil health index (SHI) and crop productivity across different soil layers. We conducted a 3–year field experiment with four treatments: a blank control with no straw return (NR), straw return treatments with shallow return (SR), mulch return (MR) and deep return (DR), and the straw application rate was 10,500 kg/ha. The results showed that it was the microbial indicators that dominated the effects on soil health, rather than soil organic carbon (SOC). Specifically, we found that the SR treatment exhibited the highest extracellular enzyme activities of both hydrolases and oxidases in the subsoil, and the peroxidase (PEO) activity was 758.99 nmol/g/h. In addition, compared with MR and DR treatments, the abundance of symbiotroph fungi in SR treatment increased by 78.41% and 54.38%, releasing more nutrients to the soil. Hence, SR treatment increased SHI mainly by increasing the PEO activity and NO3−–N content, and SR treatment significantly increased SHI by 25.59% and 22.16% compared with MR and DR treatments. By contrast, the DR treatment greatly increased the topsoil SHI by 43.33% and 58.98% compared with SR and SM treatments, mainly due to the enhanced microbial biomass N (MBN) and dissolved organic nitrogen (DON). The DR treatment in topsoil had the lowest soil bulk density (BD) which enhanced Bacteroidota but decreased Methylomirabilota abundance, thus resulting in the accumulation of MBN. Moreover, DR treatment led the highest maize yield which increased with an increasing SHI. To conclude, DR treatment is an effective method to improve SHI and crop productivity in nutrient‐rich topsoil, while SR treatment has a much better effect in the subsoil. Our results will provide a theoretical paradigm for selecting straw return strategies, which is crucial for promoting soil health and food productivity, achieving high crop yields, and supporting sustainable agricultural development.

Therefore, the purpose of the article is to study certain aspects of the functioning of agriculture in the Novgorod region, which act as determinants of the development of the industry in the context of digitalization. The paper identifies the factors influencing the digital transformation of agricultural organizations, as well as identifies the specifics of the functioning of the industry in the region during the transition to a digital business model.

Access to credit and scale efficiency: Evidence from family farms in East China

Productivity improvement is an important driving force for developing countries to accelerate the development of agricultural sectors and promote the transformation of economic structures. However, few studies have focused on the impact of credit access on family farms’ scale efficiency, a contributor to productivity changes. We address this gap by using data collected from a survey of 565 family farms in East China. The stochastic frontier input distance function (SFIDF) is utilized to measure the scale efficiency, and the endogenous switching regression model (ESRM) is employed to estimate average treatment effect (ATT) and address the selection bias. The empirical results show that the average scale efficiency is 0.768, with credit users and non-users averaging 0.802 and 0.737, respectively. Most family farms operate below their optimal production scale, and only about 14.5% of family farms exceed this optimal scale. Access to credit has significantly improved the scale efficiency of family farms and has not contributed to the excessive pursuit of scale expansion for financial subsidies. These findings are validated by robustness checks. The conclusions of our study have important implications for developing countries seeking to increase financial support for agricultural development.

A multi-omics approach reveals differences in toxicity and mechanisms in rice (Oryza sativa L.) exposed to anatase or rutile TiO2 nanoparticles

Titanium dioxide nanoparticles (TiO2 NPs) have been widely used in agriculture, which increased the risk to soil-plant systems. Studies have demonstrated that TiO2 NPs can induce phytotoxicity. However, the toxicity mechanisms, particularly under the stress of TiO2 NPs with different crystalline forms, remain inadequately reported. In this study, we combined transcriptomics and metabolomics to analyze the toxicity mechanisms in rice (Oryza sativa L.) under the stress of anatase (AT) or rutile (RT) TiO2 NPs (50 mg/kg, 40 days). The length (decreased by 1.1-fold, p = 0.021) and malondialdehyde concentration (decreased by 1.4-fold, p = 0.0027) of rice shoots was significantly reduced after AT exposure, while no significant changes were observed following RT exposure. Antioxidant enzyme activities were significantly altered both in the AT and RT groups, indicating TiO2 NPs induced rice oxidative damage (with changes of 1.1 to 1.4-fold, p < 0.05). Additionally, compared to the control, AT exposure altered 3247 differentially expressed genes (DEGs) and 56 significantly differentially metabolites in rice (collectively involved in pyrimidine metabolism, TCA cycle, fatty acid metabolism, and amino acid metabolism). After RT exposure, 2814 DEGs and 55 significantly differentially metabolites were identified, which were collectively involved in fatty acid metabolism and amino acid metabolism. Our results indicated that AT exposure led to more pronounced changes in biological responses related to oxidative stress and had more negative effects on rice growth compared to RT exposure. These findings provide new insights into the phytotoxic mechanisms of TiO2 NPs with different crystalline forms. Based on the observed adverse effects, the study emphasizes that any form of TiO2 NPs should be used with caution in rice ecosystems. This study is the first to demonstrate that AT is more toxic than RT in paddy ecosystems, providing crucial insights into the differential impacts and toxic mechanisms of TiO2 NPs with different crystalline forms. These findings suggest prioritizing the use of RT when TiO2 NPs are necessary in agricultural development to minimize toxicity risks.

Chatbot for Promoting Best Crop Management Practices to Rice Farmers in Odisha, India

The increasing penetration of mobile phones has made it easier to reach remote farmers and bridge the knowledge gap between them and researchers/extension workers and agricultural stakeholders. Farmers need concise, context-specific, information to address the challenges which arise due to lack of near-real time updates. Scaling up innovative agricultural technologies is essential to ensure these advancements reach the farmers for their benefit. Chatbots represent an informative tool for delivering the latest agricultural developments to farmers in a user-friendly and interactive format. Chatbots can deliver information on best agronomic practices, weather forecast, market information thereby improving the decision-making capacity of farmers. This paper discusses the development of a rule-based chatbot under a pilot-study and presents findings from a user study conducted with 102 farmers in Odisha, India in 2021. The content topics were decided using a participatory approach wherein farmers selected the topic of interests and information required. The content was developed using the digital tools Rice Crop Manager (RCM), Seed Cast and Rice Knowledge Bank (RKB), developed and deployed by International Rice Research Institute (IRRI). The chatbot is hosted on Facebook messenger platform and needs the internet support to operate. Farmers having this app can use the chatbot without any additional expense. The results indicate that farmers acknowledged and appreciated interactive features of chatbot and the content but expressed a desire for more comprehensive information on insect-pest management and other crop management practices. The findings highlight the potential of chatbot as a complementary channel to disseminate agro advisories, complementing the existing agricultural extension services. The study has its limitations in terms of small sample size which may or may not represent the variability of the entire population of the area.

Features of organic agriculture development in Asian countries

Abstract The implementation of Sustainable Development Goals stimulates the use of new innovative technologies in production processes of the most resource-intensive types of economic activity in most countries of the world. The modern agricultural sector, which uses land and water resources to ensure food security in countries, aims to preserve soil fertility, the quality of water resources, air and biodiversity. That is why organic agriculture is gaining popularity not only in developed, but also in lower-income countries, including Asian countries. In recent years, countries such as China and India have increased the production of various types of products several times; moreover, their consumption is constantly increasing, which is the basis for achieving the goal of preserving the health of the nation. The study is aimed at identifying natural and economic factors in the development of production, consumption and export of organic products; existing risks. The choice of the object of study is due to the fact that China, India and Indonesia are the leading countries, among the top ten countries in terms of population, these countries are large in extent, in other words, the size of their territory allows them to produce various types of agricultural products; Vietnam and Thailand were chosen due to the fact that the countries are quite unique in terms of climatic conditions, which is why they produce unique types of products and have been actively increasing the production of organic products in recent years. Based on the methods of structural and comparative analysis, aligning time series, stable trends towards an increase in export volumes were identified, and the reasons for the increase in the production of organic products were substantiated.

The Effect of Farmer’s Cognition on the Inconsistency Between Behavior and Intention in Manure Application

Manure utilization in China is below optimum due to the inconsistency between farmers’ behavior and their intention to apply manure to their crops. With increasing constraints on the availability of chemical fertilizer and their impact on the environment, understanding how farmers’ perceptions affect their intention and behavior toward manure application is an issue for the implementation of sustainable agricultural development. This study uses primary survey data from 653 farmers. A probit model was used to assess the influence of cognition on farmers’ intentions, behavior, and the inconsistency between them in the use of manure application. Heterogeneity analysis was conducted to identify differences between farmers with different education levels and operation scales. The results showed that enhancing subjective norms, perceived behavioral control, and behavioral attitudes could increase their intention and behavior. Furthermore, improving the perceived behavioral control and behavioral attitudes of farmers would reduce the inconsistency between behavior and intention. In addition, some differences were identified in the role of farmers’ cognition with different education levels and operation scales. In general, it is necessary to enhance farmers’ comprehensive cognition of the value of manure through publicity and popularization of technology, reduce farmers’ perceptions about difficulties in applying manure through new policies and subsidies, and stimulate farmers’ enthusiasm to participate in the practice.

Effects of Tillage Depth and Lime Application on Acidification Reduction and Nutrient Availability in Vertisol Soil

Cropland acidification seriously restricts sustainable agricultural development. The main purpose of this study was to determine whether deeper tilling could alleviate topsoil acidification to improve the quality of arable land. A soil column incubation experiment simulating tillage depths (10 cm, 30 cm and 50 cm) and lime addition was conducted to determine their effects on soil acidification improvement. The changes in soil pH, exchangeable acidity, ammonium nitrogen (NH4+-N), nitrate nitrogen (NO3−-N), available phosphorus (AP), and microbial phospholipid fatty acids (PLFA) were analyzed. Tillage depth, lime application, and their interaction all had significant impacts on soil pH. T50 (simulated tillage depth of 50 cm) and T50+Lime (simulated tillage depth of 50 cm plus lime) treatments significantly increased the topsoil pH from 5.41 to 6.35 and 7.12, respectively. T50 treatment significantly reduced the soil exchangeable acid content compared to the T10 treatment. The nutrient accumulation along soil column indicated that the T50 and T50+Lime treatments significantly increased NO3−-N and AP content in the &gt;30–50 cm soil layer. Compared with T30, NO3−-N accumulation in the &gt;30–50 cm soil layers of T50 and T50+Lime treatments was 6.62 and 7.93 times higher, respectively. The accumulation of AP in the &gt;30–50 cm soil layers of the T50 and T50+Lime treatments was 1.33 and 1.54 times higher than in the T30 treatment, respectively. These findings imply tillage up to 50 cm without exogenous materials could be a potential measure to reduce topsoil acidification and increase nutrition availability of &gt;30–50 cm soil layers. Tillage of up to 30 cm combined with lime application confers greater benefits, which would particularly impact crops with shallow root systems. Subsequent field experiments will be conducted to further investigate the efficacy of these strategies in enhancing crop yield.

Smart City Aquaculture: AI-Driven Fry Sorting and Identification Model

The development of smart agriculture has become a critical issue for the future of smart cities, with large-scale management of aquaculture posing numerous challenges. Particularly in the fish farming industry, producing single-sex fingerlings (especially male fingerlings) is crucial for enhancing rearing efficiency and could even provide key support in addressing future global food demands. However, traditional methods of manually selecting the gender of broodfish rely heavily on experienced technicians, are labor-intensive and time-consuming, and present significant bottlenecks in improving production efficiency, thus limiting the capacity and sustainable development potential of fish farms. In response to this situation, this study has developed an intelligent identification system based on the You Only Look Once (YOLO) artificial intelligence (AI) model, specifically designed for analyzing secondary sexual characteristics and gender screening in farmed fish. Through this system, farmers can quickly photograph the fish’s cloaca using a mobile phone, and AI technology is then used to perform real-time gender identification. The study involved two phases of training with different sample sets: in the first phase, the AI model was trained on a single batch of images with varying parameter conditions. In the second phase, additional sample data were introduced to improve generalization. The results of the study show that the system achieved an identification accuracy of over 95% even in complex farming environments, significantly reducing the labor costs and physical strain associated with traditional screening operations and greatly improving the production efficiency of breeding facilities. This research not only has the potential to overcome existing technological bottlenecks but also may become an essential tool for smart aquaculture. As the system continues to be refined, it is expected to be applicable across the entire life cycle management of fish, including gender screening during the growth phase, thereby enabling a more efficient production and management model. This not only provides an opportunity for technological upgrades in the aquaculture industry but also promotes the sustainable development of aquaculture. The smart aquaculture solution proposed in this study demonstrates the immense potential of applying AI technology to the aquaculture industry and offers strong support for global food security and the construction of smart cities.

Assessing the Impact of Casing Material Thickness on Yield and Biological Efficiency of Milky Mushroom (Calocybe indica P&amp;C)

Calocybe indica, known as the milky mushroom, has significant potential for agricultural expansion and economic development, particularly in West Bengal, India. This study investigates the impact of different casing material thicknesses (0.5”, 0.75”, 1.0”, and 1.5”) on the yield and biological efficiency of C. indica. Using a Completely Randomized Design (CRD), the effects on primordia initiation, sporophore maturation, yield, and biological efficiency were assessed. Results indicated that a casing thickness of 1.0” was optimal, leading to the quickest primordia initiation (10.4 days) and sporophore maturation (9 days), and yielding the highest total yield (717.5 g) and biological efficiency (71.75%). In contrast, thinner and thicker casings resulted in lower yields and efficiencies. The findings suggest that a 1.0” casing thickness significantly enhances C. indica cultivation, providing practical recommendations for commercial mushroom farming. This optimization can support the development of milky mushroom farming in West Bengal, offering new opportunities for local farmers and contributing to regional agricultural diversification and economic growth.

A Review: Progress in the Mitigation of Soil Continuous Cropping Obstacles by Biochar Application in Agricultural System

Under the dual pressure of agricultural economic development and limited land resources, the continuous cultivation in same area has been a mainstream pattern. The continuous cropping obstacle has seriously impaired the soil physicochemical properties and soil microflora, hindering the sustainable development of agriculture. Various strategies have been used to mitigate the negative effects caused by continuous cropping; however, they cannot be solved effectively. Recently, biochar, as a new type of soil conditioner, has been found to be able to utilize its special physicochemical properties and adsorption properties to improve soil quality conditions. Besides, biochar application is one of the effective methods to reduce the obstacles of soil continuous cropping. In this paper, we reviewed the causes of soil continuous cropping obstacles and their effects on soil and plant, and emphatically analyzed the regulatory role and potential limitations of biochar in alleviating soil continuous cropping obstacles. For example, the type of raw material, pyrolysis conditions of biochar and differences in soil types would yield different effects on the efficiency of biochar on soil continuous cropping obstacles mitigation, Furthermore, other influenced factors, such as the adsorption of biochar on root secretion, the interactions among plants, soils, and microorganisms, need to be investigated. This article provides theoretical support for the application of biochar in in alleviating soil continuous cropping obstacles.

Right to Food and Sustainable Food Systems in Nepal: Legal Frameworks, Achievements, and Challenges

Food insecurity remains a persistent challenge in Nepal. The right to food is a fundamental human right recognized in various international conventions and national legal frameworks. The Right to Food and Food Sovereignty Regulation was drafted by the Ministry of Agriculture and Livestock Development, Nepal, and approved by the Council of Ministers in March 2024. The introduction of legal frameworks to ensure food security and their effective implementation is one of the key action tracks identified in Nepal’s National Food System Transformation Pathway. However, several challenges hinder the effective implementation of this regulation, including the availability of financial resources, technical manpower, the establishment of fair price shops, and the technical capacity of the implementing agency. Additionally, policy coherence across government tiers, the interests of external development partners, and certain cultural factors pose significant obstacles to the successful implementation of the regulation's provisions. A comprehensive approach is required, combining legal reforms, economic support, and social initiatives, to transform the right to food from a theoretical concept into a tangible reality for all Nepali citizens. This paper highlights the key provisions, the development process of the regulation, the roles of key stakeholders, and the challenges in its effective implementation. Int. J. Appl. Sci. Biotechnol.
