Crop management factors influencing yield and quality of crop residues
In the semi-arid tropics, over two-third’s of the world’s people depend on agriculture within which livestock play a major role in building rural livelihoods. Crop residues (fodder/stover) are important feed resources for ruminants. This review was undertaken with the objective of improving understanding of the role of various crop management factors in affecting the productivity and quality of...
متن کاملTillage and crop residue effects on soil carbon and carbon dioxide emission in corn-soybean rotations.
Soil C change and CO2 emission due to different tillage systems need to be evaluated to encourage the adoption of conservation practices to sustain soil productivity and protect the environment. We hypothesize that soil C storage and CO2 emission respond to conservation tillage differently from conventional tillage because of their differential effects on soil properties. This study was conduct...

متن کاملLiquefaction of Crop Residues for Polyol Production
The liquefaction of crop residues in the presence of ethylene glycol, ethylene carbonate, or polyethylene glycol using sulfuric acid as a catalyst was studied. For all experiments, the liquefaction was conducted at 160°C and atmospheric pressure. The mass ratio of feedstock to liquefaction solvents used in all the experiments was 30:100. The results show that the acid catalyzed liquefaction pro...
متن کاملTrading carbon for food: global comparison of carbon stocks vs. crop yields on agricultural land.
Expanding croplands to meet the needs of a growing population, changing diets, and biofuel production comes at the cost of reduced carbon stocks in natural vegetation and soils. Here, we present a spatially explicit global analysis of tradeoffs between carbon stocks and current crop yields. The difference among regions is striking. For example, for each unit of land cleared, the tropics lose ne...
