Over Time

Crop residues are an important source of plant nutrients. However, information on the various methods of residue management on micronutrients in soil and wheat (Triticum aestivum L.) over time is limited. A long-term (84-year) agroecosystem experiment was assessed to determine the impact of fertilizer type and methods of crop residue management on micronutrients over time under dryland winter wheat-fallow rotation. The treatments were: no N application with residue burning in fall (FB), spring (SB), and no residue burn (NB); 45 kg N ha−1 with SB and NB; 90 kg N ha−1 with SB and NB; pea vines; and farmyard manure (FYM) and a nearby undisturbed grass pasture (GP). Wheat grain, straw, and soil samples from 1995, 2005, and 2015 were used to determine tissue total and soil Mehlich III extractable Mn, Cu, B, Fe, and Zn, and soil pH. After 84 years, extractable Mn and B in the top 10 cm of soil decreased in all plots, except for B in FYM and SB. The FYM plots had the highest extractable Mn (114 mg kg−1) in the top 10 cm soil; however, it declined by 33% compared to the GP (171 mg kg−1). Extractable Zn in the top 10 cm of soil increased with FYM while it decreased with inorganic N application in 2015; however, total Zn in grain increased by 7% with inorganic N (90 kg ha−1) application compared to FYM application. The results suggest that residue management had similar impact on soil micronutrients. Inorganic N and FYM application can be integrated to reduce micronutrient losses from cultivation.

The Impact

Society is increasingly demanding a more sustainable management of agro-ecosystems in a context of climate change and an ever growing global population. The fate of crop residues is one of the important management aspects under debate, since it represents an unneglectable quantity of organic matter which can be kept in or removed from the agro-ecosystem. The topic of residue management is not new, but the need for global conclusion on the impact of crop residue management on the agro-ecosystem linked to local pedo-climatic conditions has become apparent with an increasing amount of studies showing a diversity of conclusions. This study specifically focusses on temperate climate and loamy soil using a seven-year data set. Between 2008 and 2016, we compared four contrasting residue management strategies differing in the amount of crop residues returned to the soil (incorporation vs. exportation of residues) and in the type of tillage (reduced tillage (10 cm depth) vs. conventional tillage (ploughing at 25 cm depth)) in a field experiment. We assessed the impact of the crop residue management on crop production (three crops—winter wheat, faba bean and maize—cultivated over six cropping seasons), soil organic carbon content, nitrate (${\mathrm{NO}}_{3}^{-}$), phosphorus (P) and potassium (K) soil content and uptake by the crops. The main differences came primarily from the tillage practice and less from the restitution or removal of residues. All years and crops combined, conventional tillage resulted in a yield advantage of 3.4% as compared to reduced tillage, which can be partly explained by a lower germination rate observed under reduced tillage, especially during drier years. On average, only small differences were observed for total organic carbon (TOC) content of the soil, but reduced tillage resulted in a very clear stratification of TOC and also of P and K content as compared to conventional tillage. We observed no effect of residue management on the ${\mathrm{NO}}_{3}^{-}$ content, since the effect of fertilization dominated the effect of residue management. To confirm the results and enhance early tendencies, we believe that the experiment should be followed up in the future to observe whether more consistent changes in the whole agro-ecosystem functioning are present on the long term when managing residues with contrasted strategies.

The Impact

Crop residues, the byproduct of crop production, are valuable natural resources that can be managed to maximize different input use efficiencies. Crop residue management is a well-known and widely accepted practice, and is a key component of conservation agriculture. The rapid shift from conventional agriculture to input-intensive modern agricultural practices often leads to an increase in the production of crop residues. Growing more food for an ever-increasing population brings the chance of fast residue generation. Ecosystem services from crop residues improve soil health status and supplement necessary elements in plants. However, this is just one side of the shield. Indecorous crop residue management, including in-situ residue burning, often causes serious environmental hazards. This happens to be one of the most serious environmental hazard issues witnessed by the agricultural sector. Moreover, improper management of these residues often restrains them from imparting their beneficial effects. In this paper, we have reviewed all recent findings to understand and summarize the different aspects of crop residue management, like the impact of the residues on crop and soil health, natural resource recycling, and strategies related to residue retention in farming systems, which are linked to the environment and ecology. This comprehensive review paper may be helpful for different stakeholders to formulate suitable residue management techniques that will fit well under existing farming system practices without compromising the systems’ productivity and environmental sustainability.

Crop Residue Management

Crop residue management (CRM) through conservation agriculture can improve soil productivity and crop production by preserving soil organic matter (SOM) levels. Two major benefits of surface-residue management are improved organic matter (OM) near the soil surface and boosted nutrient cycling and preservation. Larger microbial biomass and activity near the soil surface act as a pool for nutrients desirable in crop production and enhance structural stability for increased infiltration. In addition to the altered nutrient distribution within the soil profile, changes also occur in the chemical and physical properties of the soil. Improved soil C sequestration through enhanced CRM is a cost-effective option for reducing agriculture's impact on the environment. Ideally, CRM practices should be selected to optimize crop yields with negligible adverse effects on the environment. Crop residues of common agricultural crops are chief resources, not only as sources of nutrients for subsequent crops but also for amended soil, water and air quality. Maintaining and managing crop residues in agriculture can be economically beneficial to many producers and more importantly to society. Improved residue management and reduced tillage practices should be encouraged because of their beneficial role in reducing soil degradation and increasing soil productivity. Thus, farmers have a responsibility in making management decisions that will enable them to optimize crop yields and minimize environmental impacts. Multi-disciplinary and integrated efforts by a wide variety of scientists are required to design the best site-specific systems for CRM practices to enhance agricultural productivity and sustainability while minimizing environmental impacts.

The study aimed to examine the present status of rice crop residue management and its impact on farmers’ livelihood covering two sub-districts in Mymensingh district of Bangladesh. A total of 100 farmers (50 for crop residue practicing farmers and 50 for the farmers involved in traditional farming) were selected randomly for data collection. A combination of descriptive, statistical and mathematical techniques were applied to achieve the objectives and to get the meaningful results. The results of descriptive statistics showed that retention was found higher in far distance plots from homestead. No retention of crop residues was found in case of Aus and Aman rice. The whole retention was found only in case of Boro rice. The shortage of labour in season and the wage rate were also important factors for the retention of crop residues. However, farmers’ perceptions about the use of crop residues were mostly adding organic matter to the crop field followed by mulching and feeding animal. The recycling of resources among crop retention and livestock has the great potential to return a considerable amount of plant nutrients to the soil in the rice based crop production systems. Due to crop residue practices, crop and livestock both were benefited through resource interdependences. The sampled farmers were benefited from retention of crop residues by improving soil quality, soil moisture, etc.; and farmers used less amounts of fertilizer, irrigation water, etc. for the succeeding crops. Consequently, succeeding crop productivity, profitability and annual income were increased significantly. The result of logit regression model shows that age of household head, farm size, agricultural income and non-farm income were found as significant variables in explaining the variation in crop residue adoption of farm households. To assess the livelihood pattern of sample farm households through asset pentagon approach, noteworthy improvement was found s on different capitals. The study identified some problems regarding crop residue management and finally, recommended that if the farmers get proper training for such management, it would be helpful to improve their livelihood.Progressive Agriculture 27 (2): 189-199, 2016

The Impact

<p>Crop residues are a significant source for soil N<sub>2</sub>O emissions and major component affecting the C storage in arable soils. The balance between C sequestration and N<sub>2</sub>O emissions is delicate and depends on the type of residues and its management. Thus, residue management might be a feasible option to reduce the GHG footprint of crop production. However, the mitigation potential of residue management is highly variable and strongly affected by the crop residue quality (C and N content, C:N ratio, concentrations of lignin, cellulose and solutes), field management (incorporation depth, amount applied) as well as soil physical and soil biogeochemical properties. In the frame of the EU-ERAGAS project RESIDUEGAS, we investigated the impact of different crop residue qualities on soil respiration and reactive N fluxes as well as soil ammonium (NH<sub>4</sub><sup>+</sup>) and nitrate (NO<sub>3</sub><sup>-</sup>) concentrations in order to test and possibly improve existing IPCC emission factors for GHG emissions from crop residue management.</p><p>In this study, we used sieved and homogenized soil columns of 8 cm height and 12 cm diameter filled with arable soil taken from a site near Gießen, Germany. Soil columns were incubated in the laboratory for 60 days at constant soil temperature (15°C) and water-filled pore space (60 %). Residues from nine different crops (oilseed rape, winter wheat, field pea, maize, potato, mustard, red clover, sugar beet, ryegrass) were re-wetted according to field moisture level and incorporated over approx. 0-4 cm topsoil layer one week after soil re-wetting and start of the measurements. The CO<sub>2</sub>, N<sub>2</sub>O (as well as NO and NH<sub>3</sub>) fluxes were measured automatically using a dynamic chamber approach. Soil samples were additionally analyzed for soil NH<sub>4</sub><sup>+</sup> and NO<sub>3</sub><sup>-</sup> concentrations at specific time steps during the experiment.</p><p>Re-wetting of the dry soil immediately resulted in a sharp increase of soil N<sub>2</sub>O and CO<sub>2</sub> emissions, which, however, was less pronounced than peak emissions following residue incorporation. Those were 4-5 times higher as compared to soil cores without residue amendment. Elevated emissions were short-lived and declined to background levels within 10 days for N<sub>2</sub>O and within 30 days for CO<sub>2</sub>. However, a small but significant period of higher than background N<sub>2</sub>O emissions was observed in the second half of the incubation period, which might be directly related to the decomposition of slower decomposable organic matter such as lignin and cellulose from crop residues. Generally, the emission magnitude was strongly affected by the crop residue quality, with highest N<sub>2</sub>O as well as CO<sub>2</sub> emissions being calculated for residues with a narrow C:N ratio. However, C:N ratio was not the single explaining factor. The range of calculated emission factors (fraction of cumulatively emitted N<sub>2</sub>O-N to crop residue N input) over a 60 day period was larger than the range given by IPCC in 2006.</p>

Crop Residue Management

An effort has been made to study the effect of climate change on crop residues and need of crop residue management in present environmental condition. Crop residue management as an important practiced in the rice–wheat cropping system. In present condition, cropping season is shifted according to changing rainfall pattern. In case of wheat and rice-based cropping system, there is a chance of crop loss due to occurrence of rainfall at harvesting stage so, to cope with that situation combine harvesters become more popularize among farmers because of effective harvesting in less time, less effort and minimum labour cost. But it lefts a huge amount of loose straw in their field and farmers face difficulties in the disposal of huge straw in the field in short time has compelled to go for crop residue burning to save time as well labour. Farmers can use that residues in vermi-composting, can be fed to animals after urea treatment etc. without burning. In recent year 30-40% maize crop have been damaged due to hailstorm at its grain filling stage so these residues can be used in making silage. Removal of straw or stover can result in significant loss of soil organic carbon (SOC). If they are used as bedding for livestock, then much of the carbon may be returned to the soil as manure (Lal et al., 1998). When crop-residue is incorporated into soil, the soil’s physical properties and its water-holding capacity are enhanced. Unlike in earlier conservation farming systems wherein retained stubble was mulched and slashed, now it is mostly burned by the farmers. Vermicomposting, waste decomposer, Green Manuring, use of zero tillage machine, silage making and urea treated straw are the best option to crop residue management. The study aimed to examine the present status of crop residue management of major crops and its impact on farmers’ livelihood covering eleven blocks in Banka district of Bihar.

The authors study the corn crop residue management system for 16 provinces in northern Thailand encompassing 127 agricultural cooperatives (co-ops), 974 corn fields and 274 customers. To solve the system's problems, we find clusters where co-ops will pick up crop residues from corn fields, process them into biomass fuel and sell the fuel to customers. Each cluster consists of a co-op, a set of corn fields and a set of customers, the latter two being on separate routes from the co-op. To minimize the system's transportation cost and balance transportation cost between clusters, we propose a mathematical model with two objective functions, construct two heuristics, and apply the two heuristics to solve the problem.

Crop Residue Management

A field experiment was carried out at Krishi Vigyan Kendra, Katihar, Bihar in jurisdiction of Bihar Agricultural University Sabour, Bhagalpur during 2014 to 2018 with the objective to find out suitable crop residue management option under rice- wheat cropping system in Inceptisols of Seemanchal area of Bihar. The results after four years clearly indicates that the crop residue management practices involving  incorporation of residues improved favorably and significantly the soil properties such as bulk density, infiltration rate, mean weight diameter, aggregate stability, electrical conductivity, organic carbon, available nitrogen, phosphorus and potassium, bacterial and fungal population, enzyme dehydrogenase and phosphatase activity in the soil and increased the grain yields of rice and wheat crop in the system over removal or burning of crop residue practices. Due to increased availability of readily decomposable organic matter in the form of crop residue and freshly incorporated green manure, the microbial population increased dramatically when crop residues are incorporated in the soil which might be responsible for increased enzyme phosphatase and dehydrogenase activity, decrease in bulk density, increase in granulation and aggregation and thus infiltration rate. The incorporation of crop residues with or without green manuring found promising for the environmental friendly and effective utilization of the crop residues under prevailing rice wheat system in this area.
