Farmer perspectives on crop residue burning and sociotechnical transition in Punjab, India

Burning rice stubble is a common practice for millions of farmers across the Indo-Gangetic Plains. Though burning represents a low input, cost-effective strategy of crop residue management (CRM), it produces harmful air pollution, and it releases greenhouse gasses. Large-scale transition to no-burn CRM in northwest India will require social and technological change. We analyze data from 60 focus group discussions and 24 interviews with farmers and key actors related to agriculture in Punjab, and we discuss our findings using a sociotechnical systems framework. Farmers and key informants alike illustrate the complexity of CRM, highlight the diversity of machinery used in rice-wheat cropping, and identify a multi-level and unequal policy landscape that constricts the time available to implement no-burn CRM between harvesting rice and sowing wheat crops. Farmer responses reveal mistrust and uncertainty regarding current incentives for no-burn CRM, including subsidies for purchasing no-burn CRM machinery and fines for burning. Nonetheless, farmers support new long-term price subsidies for alternate rice varieties, crops, and fuel. In addition to cost-reduction measures, farmers and key informants voice support for local demonstrations of no-burn CRM, promoting agricultural services through social organizations, and being free to choose how to best reduce or eliminate burning on their fields. In contrast to studies that consider individual farmers’ willingness to accept payment for reduced burning, our findings emphasize the importance of considering the political and technological aspects of CRM in Punjab. Respondents acknowledge the importance of improving individual incentives while working through local organizations to provide wider access to no-burn CRM technology and address information asymmetries.

Assessing and enhancing sustainable rice straw management for environmental conservation in Yen Thanh District, Nghe An Province, Vietnam

This study assessed the current management of rice straw in Yen Thanh District, Nghe An Province, and propose solutions for sustainable agricultural development. A survey was conducted with 120 households in four communes to determine straw use and management practices. The findings revealed six common methods of using and managing rice straw in Yen Thanh District: open burning, burying, mushroom plantation, using it for husbandry feeding, selling, and giving it to others. These practices vary based on the crop season. Open burning is the most prevalent practice, accounting for 98.15% and 89.52% during the winter-spring and summer-autumn harvests, respectively. A crucial step in establishing a pollution control and management database is a comprehensive inventory of emissions. Consequently, authorities and environmental scientists are currently focusing on the emission inventory, particularly emissions resulting from open-burning rice straws. The estimated total amount of rice straw produced annually is 159,732 tons, with 151,384 tons being directly burned in the fields. This burning releases significant emissions, including 1,005.18 tons of PM2.5, 1,102.08 tons of PM10, 21.80 tons of SO2, 142,543.18 tons of CO2, and more, negatively impacting the environment, human health, and agriculture. Additionally, it was observed that most farmers are inclined to continue burning rice straw out of habit in the upcoming years. The study suggests promoting alternative straw management practices such as mushroom cultivation, biochar production, and organic fertilizer production to reduce burning and its associated negative consequences. This information would be invaluable for managers to effectively plan for the future management of rice straw

Effect of bone ash and rice husk ash on the unconfined compressive strength of silt soil

This study investigated the soil stabilization potential of ash obtained from the calcination of cattle bones and ash produced by burning rice husks on silty soil. After the cattle bones were first crushed and burned, they were calcined at 800°C for 1 hour, allowed to cool, ground, and sieved with a sieve with a 75-micrometer opening to obtain bone ash (BA). To get rice husk ash (RHA), rice husks were burned, ground, and sieved through a 75-micrometer aperture. A silt soil sample taken from a depth of 3-4 meters from the center of Sakarya Province in Yenigün District of Adapazarı district was used to stabilize it. RHA was added as ground and unground, 10% by weight of the samples, BA as 7% by weight of the samples, and BA and RHA as 7% BA + 10% RHA by weight of the samples. Unconfined compressive strength (UCS) tests were performed for this research. The results showed that the UCS value increased with the addition of BA and RHA as the curing time increased for 7% BA, 7%BA+10% RHA, and 10% ground RHA, while 10% unground RHA lost strength. Caused Therefore, 7%BA+10%RHA can be used to increase the UCS value of the soil. Instead of allowing bones to be disposed of in the environment, calcined bone ash should be encouraged to sustain people's livelihood on stabilized soils.

Susut Bobot dan Kadar Air Tajuk Tanaman Pakcoy Akibat Pengaruh Jenis Media Tanam dan Konsentrasi Nutrisi AB Mix

Pakcoy (Brassica rapa subsp. chinensis) is a type of vegetable commonly cultivated using hydroponic systems. The weight loss and moisture content of pakcoy plant shoots can be influenced by the type of growing media and the concentration of AB Mix nutrients. Each type of growing medium has distinct physical and chemical properties. The combination of different AB Mix nutrient concentrations with various growing media types results in varying weight loss and moisture content in the plant shoots. Pakcoy plants with lower weight loss and higher shoot moisture content exhibit better storage resistance. The research method employed was a Factorial Randomized Block Design with two factors: the first factor being the type of growing media (burnt rice husk, cocopeat, rockwool), and the second factor being the concentration of AB Mix nutrients (1,000, 1,200, and 1,400 ppm). The results indicated that rockwool, combined with an AB Mix nutrient concentration of 1,000 ppm, resulted in the lowest weight loss and the highest shoot moisture content compared to other treatments.

Investigating the potential of delignified rice husk as a carbon-rich resource for extracting glucose and its utilization in biocement production through fungal isolates.

Burning rice straw is now a significant issue faced by different regions in India, as its burning releases harmful gases, mainly carbon dioxide. Various techniques are now in trend to utilize the rice straw, e.g., producing compressed natural gas using rice straw, bioethanol, etc., as a substrate for various microorganisms. A high quantity of non-utilized rice husk generates more ideas for its proper utilization. The cellulose, hemicellulose, and lignin found in rice straws can be a fungi growth medium. In this research, the delignification of rice husk is done by acid (2% and 4% H2SO4) and alkali (2% and 4% NaOH) at 121°C at 103kPa for 1h to obtain crude carbon source which is further utilized for biomineralization. The glucose is subjected to qualitative and quantitative analysis using Molisch's and Dinitro salicylic tests. The delignification process showed a positive outcome when 2% H2SO4 is utilized maximum yield of 5.9 ug/ml free sugar concentration. Representing the highest glucose yield compared to the experiment's other acid and base substances used. Various techniques such as field emission-scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), and Fourier transformed infra-red (FTIR) spectroscopy are employed to examine surface and chemical alterations. The 2% H2SO4 pretreated rice husk is utilized for microbial-induced calcite precipitation using fungal isolates S1 (3), S1 (18), and S4 (1). The calcite and vaterite produced by biomineralization are confirmed using XRD for fungal isolates namely, S1 (3), S1 (18), and S4 (1) having percentage crystallinity of 59%, 46.428%, and 62.69% percentage crystallinity respectively.

Studying the effect of using CFRP warping on strength of husk rice concrete columns

Abstract This research presents the effect of carbon fiber-reinforced polymer (CFRP) on a strength of concrete containing rice husk. Two shapes of columns (circular and square) were used to compare these two types in terms of resistance axial loading. Twelve concrete columns were casting; six are square and others are circular cross-section. All columns of each shape were divided into three groups, and each group consisted of two columns: the first group without CFRP, the second group covered with one layer of CFRP, and the last group covered with two layers of CFRP. The dimensions of the square columns were 300 mm × 300 mm and the height was 900 mm, with reinforced 4–6 mm steel bars. The circular columns were 300 mm in diameter with same height 900 mm and reinforced with 6–6 mm steel bars. Burnt rice husks are added at a rate of 10% of the amount of cement that should be added to the concrete mix. The test results showed the circular columns were the strongest and most resistant to axial loading than square columns. Also, the CFRP wrapping is very effective in strengthening circular concrete columns but significantly less effective in strengthening square concrete columns because the latter have sharp corners and flat sides.

Determination of 2,4-dichlorophenoxyacetic acid and its metabolite in soils by gas chromatography-mass spectrometry after pre-concentration using magnetic charcoal based on rice husk

A method for determining 2,4-dichlorophenoxyacetic acid (2,4-D) and its metabolite 2,4-dichlorophenol (2,4-DСР) in soils is proposed. 2,4-D and 2,4-DСР were extracted from the soil by an alkali solution. The analytes were recovered from the extract using a sorbent based on magnetite nanoparticles and coal obtained by burning rice husk, and desorbed by methanol. 2,4-D and 2,4-DСР in the concentrate thus obtained were converted to methyl esters and determined using the GC-MS method. The quantification limit (LOQ) of 2,4-D and 2,4-DCP were 3.0 μg/kg and 0.08 μg/kg, respectively. Leached black soil (from the border of Stavropol and Krasnodar Territories) was selected as a real object for analyzing the distribution of the herbicide "Ballerina" (ethylhexyl ester of 2,4-D) and its degradation product. A day after applying the herbicide, the concentration of 2,4-D in the surface layer of the soil was 119 μg/kg. Atmospheric precipitation has a significant effect on motion of 2,4-D along the soil profile. The most significant decrease in the concentration of 2,4-D was observed between 3 and 10 days after application of the herbicide. A month after application of the herbicide, the concentration of 2,4-D was 31, 18 and 11 μg/kg at the depths of 10, 30 and 50 cm, respectively; no 2,4-D was detected in the surface soil layer. Detectable amounts of 2,4-DСР appeared on 16-th day after application of the herbicide; 2,4-DСР degrades much slower than 2,4-D. After 1.5 months, the concentration of 2,4-DСР was 0.53, 0.45 and 0.22 μg/kg at the depths of 10, 30 and 50 cm, respectively. At the same time, 2,4-D was not detected throughout the soil profile.

Improving Soil Quality and Crop Yields Using Enhancing Sustainable Rice Straw Management Through Microbial Enzyme Treatments.

This study develops a model to raise public awareness about the consequences of burning rice straw after harvest, including environmental pollution, soil degradation, and increased CO2 emissions that contribute to the greenhouse effect. The distinctive feature of the research is the introduction of a post-harvest rice straw treatment process using microbial products capable of secreting cellulase enzymes, which can break down the cellulose in the straw. This process shortens the decomposition time and produces natural organic fertilizer, thus reducing cultivation costs by 60% and increasing crop yields by 20%. The experimental model was carried out in Cam My district, Dong Nai province, Vietnam, including 4 models: no microbial products; using Bio Decomposer; using NTT-01; and using NTT-02. Each experimental field had an area of 650 m². The results showed a significant reduction in straw decomposition time after 14 days of use of the products, with a decomposition rate of up to 80%, nearly twice as fast as without the products. This helps save time, produce natural organic fertilizers, reduce care costs, and increase rice yields, resulting in more income for local residents. These findings demonstrate the effectiveness of microbial treatments in sustainable agriculture and their potential for a broader application in the management of agricultural waste.

Crop Residue Management Options in Rice - Wheat Cropping Systems: A Case Study of the Indian Experience

The dominant agricultural system in India is the rice-wheat system, and the problems posed by climate change and declining soil health are endangering the system's sustainability. High yields from the irrigated rice-wheat system have resulted in a substantial amount of wasted food. In northwest India, burning rice straw is a frequent practice that results in significant air pollution that is harmful to human health and nutritional losses. Crop residue management improvements should help achieve sustainable productivity, enable farmers to minimize nutrient and water inputs, and lower the risk associated with climate change-all of which will help prevent straw burning. The rice-wheat system's nutrition management will benefit from the prudent application of crop residues, which contain substantial amounts of plant nutrients. Long-term research on residue recycling has shown improvements in the soil's chemical, biological, and physical health. Another viable approach to managing crop residues is to use some of the excess residues to make biochar, which can be added to the soil to enhance its health, maximize its ability to use nutrients, and reduce air pollution. Mushroom cultivation may convert non-edible crop leftovers into a nutritious food source, surface mulch can suppress weed growth and retain soil moisture, and compost and biofuel can all be made from these materials. The decomposition of residues considerably boosts the soil's organic carbon and nitrogen levels. This review looks at the residues that can form in a rice-wheat farming system and how those residues can be effectively managed.

PURIFICAÇÃO ÁCIDO-BASE EXPERIMENTAL DE CASCAS DE ARROZ CARBONIZADAS: EXPLORANDO SUA EFICÁCIA NA ADSORÇÃO DE RESÍDUOS NÃO VALORIZADOS DA INDÚSTRIA DE ARROZ

The burning of rice husks produces natural silica and generates charcoal with excellent properties for the adsorption of different pollutants. The objective of this study was to enhance the adsorption properties of this industrial residue from burning rice husk through acid and base purifications. The raw coal (RC) was initially modified with HCl(aq.) and then with NaOH(aq.), and subsequently renamed MC. Efficiency was verified by the adsorption of methylene blue (MB) dye, considering a concentration of 10 mg L-1, dosage of 0.05 g L-1, pH 6.7, and 120 min. MB removal was 78% for RC and 97% for MC, with experimental capacities of 144.78 mg g-1 and 180.78 mg g-1, respectively. The kinetics were better adjusted by Avrami (R2 0.99, error <2.8%). The properties of charcoal improved with the modification, presenting a more porous structure, greater surface area and functional groups that contributed to adsorption, proving that simple purification methods, such as acid-base purification, can be crucial for waste reuse.

Pemanfaatan Limbah Sekam Padi Dalam Pembuatan Sekam Bakar dan Briket di Pendahara Kecamatan Tewang Sangalang Garing Kabupaten Katingan

Pendahara sub-district has rice fields covering an area of ​​165 hectares with an average annual rice yield of 417.5 tons. After the harvest period, there will usually be a lot of leftovers from rice milling in the form of rice husk waste (husk). There is still little use made to reduce the environmental impact resulting from rice husk waste. The use of rice husks has impacts in terms of energy, finance and ecology. From an energy aspect, rice husks can produce bioenergy through burning the husks for electricity or alternative fuels. Meanwhile, from a financial aspect, farmers can reduce production costs by using husks as value-added products such as organic fertilizer. Furthermore, in the ecological aspect, it is useful in minimizing agricultural waste and reducing pollution due to the use of husks for various environmentally friendly products such as compost or wood panels. If further processed rice husks can be made into husk charcoal which is processed into briquette products, briquettes have benefits as fuel, agricultural materials and industrial materials, for human needs. The aim of this community service activity is to use rice husk waste into burnt husks and briquettes so that it can be used as a community business opportunity. The stages of making burnt husks are making a burning tool, burning rice husks, packaging the burnt husks. The stages of making briquettes are grinding the ingredients, mixing the ingredients and molding the briquettes. The results of making burnt husks and briquettes, namely burnt husks, can be used as planting media and fertilizer for plants. In the results of making briquettes, the briquettes cannot be used because they cannot be lit, which is why briquettes require a lighter to make it easier to ignite.

Potential Nitrogen Mineralization of Agricultural Wastes in Typic Natraqualfs: Implications for Jasmine Rice

ABSTRACT Problems of salt-affected soils can be alleviated by organic amendments, but their nitrogen (N) mineralization pattern, crucial to providing proper N synchronization with crop demand, can differently be influenced by salinity and sodicity. An incubation study was carried out objectively to investigate the mineralization and kinetic release of N in three organic wastes (OWs) – rice husk (RH), rice straw (RS), burnt rice husk (BRH) in saline-sodic (SS) and sodic (Sod) soils. The OWs were mixed into the soils and inorganic N was measured under aerobic condition (field capacity) for 28 days followed by waterlogged condition until day-112. The mineral N mineralized from all OWs was, on average, <20% of N input released into the mineral N pool with RS mineralized the highest. Mineralization occurred less in SS than in Sod soil. Nitrogen mineralization peaked at 28 days with net immobilization observed after 21-day of waterlogged condition. The mineralization rate and mineralizable N pool of these OWs had a better fit to two-pool than first-order model, showing the highest quantities in respective RS, RH and BRH and fast N pools constant rate greater in SS than in Sod soils. Net N mineralization differed among OWs, soils and incubation times. The N mineralization pattern of OWs was a function of both N sources and soil salinity. The pool and rate of mineralizable N were predicted from the initial material’s total N. The findings can lead to proper N management for jasmine rice in salt-affected soils using inorganic wastes to partially supply N.

Thermal Study of the Utilization of Rice Husks Using the Forced Convection Method as Energy for a Rotating Cylinder Dryer

Small farmers in rural areas use the sun as their main energy source to dry post-harvest products. Due to limited knowledge and technology, farmers depend on the sun through direct drying. Direct use of the sun for the drying process has disadvantages in uncertain weather such as cloudy or rainy. This results in the drying process not being optimal or even stopping. This research aims to use rice husks as energy to replace direct sun drying to produce optimal temperatures so that drying time is shorter and the quality of the dried food is hygienic. Rice husk as an energy source is applied through a rotating cylinder dryer. This dryer is tailored to farmers' needs, namely easy to operate at an affordable price. This energy can be utilized sustainably because it is abundant through a forced convection system and energy conversion using a heat exchanger. The design of the compact rotary dryer includes an integrated drying chamber in one unit with the combustion furnace and a heat exchanger. The drying chamber includes a rotating cylinder and a fixed cylinder. The test results show that hot air from burning rice husks flows through the heat exchange pipes by conduction from the furnace to the walls of the drying chamber and by forced convection through an exhaust fan installed in the drying chamber. The average environmental temperature of 29.55-29.69oC has increased when using one exhaust fan to 64.46oC and two exhaust fans to 60.11oC. This drying temperature can produce shorter drying times, so it can be applied to post-harvest product drying, which is energy-efficient and sustainable for small farmers. Based on research results, rotating cylinder dryers powered by rice husks are very suitable for small farmers to replace direct sun drying.

The planting media used as treatments are paddy soil, paddy soil + chicken manure fertilizer, paddy soil + cow manure fertilizer, and paddy soil + burnt rice husk. Growth parameters observed include percentage of growth, plant height, and the number of leaves. Based on the research results, it can be seen that the growth of water jasmine stem cuttings showed significantly different responses when planted in various types of media. The best planting medium to accelerate the growth of water jasmine stem cuttings is paddy soil + cow manure fertilizer, with greater plant height and leaf count compared to the other three treatments.

Characterization of dielectric properties of residual ashes obtained from rice husk and annoni grass

This paper presents a study about the characterization of dielectric properties (dielectric constant {varepsilon }_{r} and dielectric-loss constant mathrm{tan}delta) of samples derived from two different biomass types: rice husk ash (RHA) and annoni grass ash (AGA).The procedure is carried out using the resonant cavity method along with a vector network analyzer. For this purpose, four different ashes were produced, by burning rice husk and annoni grass at two different temperatures and burning times: 400 °C/30 min (RHA40030 and AGA40030) and 800 °C/5 h (RHA8005h and AGA8005h). These ashes were combined with Bakelite to produce cylindrical samples with diameter of 30 mm and thickness of 4.5 mm, which were characterized considering the frequency in the test band for 5G technologies ({f}_{o}=3.5 GHz). Experimental results showed that the samples burnt at high temperature showed very high mathrm{tan delta } when compared to the samples burnt at low temperature, mainly for AGA8005h. These values are mathrm{tan delta }= 0.1690 and 1.4900 for RHA8005h and AGA8005h, respectively. The resulting dielectric constants are {varepsilon }_{r} = 3.87 for RHA8005h and {varepsilon }_{r} = 15.14 for AGA8005h). These very high dielectric loss tangent, indicate that these materials exhibit formidable properties for electromagnetic energy absorption, hence allowing the application as radiation-absorbent material (RAM).

Hydrogen and electricity potential generation from rice husks and persiculture biomass in Rio Grande do Sul, Brazil

The Southern region of Brazil has the highest grain and fruit production at a national level. Therefore, the biomass waste from rice and peach harvest in the Rio Grande do Sul (RS) state represents a promising source of available clean energy. This study seeks to demonstrate the average potential for biohydrogen and energy production by utilizing residues from peach cultivation rice straw and husks from 2014 to 2021. The findings reveal that an average of 2.89E+06 m³.year−1 of bioH2 theoretically obtained from the dark fermentation of rice husks and straw, with a biogas production of 1.49E+06 m³.year−1, derived from the anaerobic digestion of peach residues. After the purification process, the biogas yields an average of 4.73E+05 kg year−1 of H2, resulting in a total of up to 2.26E+08 kg year−1 when combined with the bioH2 obtained from the dark fermentation of rice residues. The results indicate an average energy of 8.50E+06 GJ year−1 potentially obtained by burning rice husks. Furthermore, for peach and rice biomass, the average energy potential is 3.37E+04 GJ year−1. Besides, considering using 2% of the bioH2 theoretically produced for green ammonia generation, the results show an amount of approximately 2.55E+04 tons. Therefore, this study is relevant since highlights the region's potential to produce clean energy from agricultural residues while presenting viable solutions to mitigate the negative environmental impacts caused by improper disposal of these materials. Moreover, these residues used for clean energy production contribute to the sustainable energy transition, reduce dependence on fossil fuels, decrease the need for nitrogenous fertilizer imports, and promote the implementation of the Circular Economy.

THE IMPACT OF RICE HUSK ASH (RHA) AS SOILLESS GROWING MEDIUM ON SAWI CAIXIN GIANT (Brassica parachinensis) GROWTH PERFORMANCE

The Sustainable Development Goal 2 (SDG 2), which aims to end hunger, enhance nutrition, and support sustainable agriculture, places a high priority on food security. The amount of rice husk ash (RHA) produced by the process of burning rice husks has increased over time, causing environmental pollution. In modern soilless agriculture, RHA has a significant potential to be used as a fertile and nutrient-rich medium. The Zero Energy Soilless Agriculture (ZESA) System is a revolutionary concept for horticultural plants that might utilize RHA as a soilless growing medium. The effect of growing medium ratio of cocopeat and RHA on plant growth performance of sawi caixin giant (Brassica Parachinensis) using ZESA system over 35 days was investigated in this study. Three different treatments, T1 (1:0), T2 (1:1), and T3 (3:1), on the growing medium ratio of cocopeat and RHA were carried out. The treatments were set up in four replicates of two individuals each using a randomised full block design. The data of plant Growth parameters such as the number of leaves and plant height were recorded every 7 days, and the fresh weight of the plants was taken on harvesting day. FTIR analysis and an elemental analyzer were used to characterise the chemical analyses of cocopeat, RHA, and fertiliser. As shown by the results, T3 treatment increased all plant growth performance parameters compared to T1 control treatment, with a value of 12.02 cm for plant height, 10 leaves, and 33.75g of fresh weight. The plant growth performance of Brassica parachinensis was improved by using a 3:1 ratio of 25% RHA as a soilless growing medium couple with application of rich nitrogen X and Y fertilisers using the ZESA System. Finally, RHA has the potential to be used as a soilless growing medium for many horticulture plants using the ZESA System.

Effect of growing media on growth and flowering of potted marigold (Tagetes erecta L.) irrigated with treated sewage water

The present study was undertaken with an objective to evaluate the effect of different soil-based and soilless growing media compositions supplemented with treated municipal sewage water and tap water in different ratios on growth and flowering of potted marigold. The experiment was conducted in a completely randomized block design comprising four media substrates (Soil, burnt rice husk [BRH], farmyard manure [FYM] and cocopeat [CP]) mixed in four different proportions (M1 to M4) and five irrigation levels (I1 to I5) of different combinations of tap water (TW) and treated sewage water (TSW). Results revealed that the media substrate composition (M4) comprising CP + BRH + FYM (25:25:50) was found to be suitable for sustaining the growth of potted marigold plants. The media had relatively higher percent N, P & K with acceptable pH and EC. The marigold plants raised in M4 media irrigated with TSW (100%) preformed significantly well for vegetative and floral characters, essential for a specimen display without any visual phytotoxicity symptoms. Number of flowers per plant and days to flowering duration were observed significantly higher in M4 compared to other media treatments. The analysis of TSW (100%) revealed higher N (0.91 ppm), P (1.67 ppm), K (24.13 ppm) with pH (7.73) and EC (2.10 ds m−1) in acceptable range.
