-hlodeling of crop residue decomposition for nutrient cycling and effectiveness of residues to control soil erosion requires information on crop-specific decomposition coefficients (k). Respiration of decomposing residues reflects the activity of the microbial community and should give an indication of the residue decomposition rate. A method for estimating k using substrate-induced respiration...

abstract in order to evaluate the effects of rice conventional herbicides on rotational second crops (lettuce, cress, clover, canola and radish), soil microbial biomass and diversity, a field and glasshouse experiments were conducted in mazandaran province and research glasshouse of ferdowsi university of mashhad, respectively. five experiments were carried out for 5 second crop separately with...

Crop residues have been considered during the past decade as alternate energy sources to supplement dwindling fossil fuel sources and enhance energy independence in the United States. Agricultural scientists have demonstrated the importance of crop residues in reducing soil erosion, enhancing the soil physical environment for plant growth, and as a reserve for major crop nutrients. In eastern N...

Suggested citation IARI (2012) Crop residues management with conservation agriculture: Potential, constraints and policy needs. Indian Foreword India being an agriculture-dominant country produces more than 500 million tons of crop residues annually. These residues are used as animal feed, for thatching of homes, and as a source of domestic and industrial fuel. A large portion of unused crop re...

crop residues management is one of the most important factors to sustain agro-ecosystems. application of plant residues as organic fertilizers has functional role on the amount of soil elements, their availability for crops and finally yield obtained. in order to investigate the effect of different crop residues and their management on providing wheat potassium requirement, a four-replicated fi...

Conservation agriculture (CA) is promoted as a cropping system that has potential to alleviate poor crop yields in smallholder farming while protecting the environment. It involves maintenance of permanent soil cover, diverse crop rotations and/or interactions; and minimum soil disturbance. CA is associated with crop residue management challenges due to low crop biomass yields and crop-livestoc...

BACKGROUND China has the world's largest tea plantation area in the world. To sustain high yields of the tea, multiple pesticides are used on tea crops to control pests. Organophosphorus (OP) pesticides are among the most widely used types of agricultural pesticides in China. As tea is a significant potential source of exposure to pesticide residues, the public concern has increased in relation...

Returning crop residue improves water conservation and storage, nutrient availability, and crop yields. We have little knowledge, however, of the residual impacts of crop residues on soil and crop production. We hypothesized that residual impacts of crop residues vary with the amount of residues used. A 10-yr study near Lincoln, NE, evaluated the residual effects of an earlier 8-yr study of var...

The presence of pesticide residues in feed and its animal products is in the focus at the present scenario in the view of WTO. The residues not only affect the public health but also cause economic losses to the livestock industry. Not only these affect the health of livestock and human beings but also affect the quality of animal products. Pesticide residues accumulate in the animals either by...

Biomass based energy generation is one of the major focus areas of renewable energy programs in India. The strength of India’s biomass resources mostly lies in the agricultural sector. A large quantity of crop residue biomass is generated in India. However, crop residue biomasses are distributed resources with variation in spatio-temporal availability and its characteristics. Competing uses of ...
