Greenhouse gas emissions under conservation agriculture compared to traditional cultivation of maize in the central highlands of Mexico
In 1991, the International Maize and Wheat Improvement Center (CIMMYT) started a field experiment in the rain fed Mexican highlands to investigate conservation agriculture (CA) as a sustainable alternative for conventional ...
Straw management, crop rotation and nitrogen source effect on carbon and nitrogen dynamics: A laboratory study
Straw incorporation, crop rotation and organic fertilizer applications have been proposed to counter the negative effects of straw burning, inorganic N fertilizer application and intensive agriculture practices for wheat ...
Global warming potential of agricultural systems with contrasting tillage and residue management in the central highlands of Mexico
Conservation agriculture based on (1) minimal soil movement, (2) retention of rational amounts of crop residue, (3) economically viable crop rotations restores soil fertility. Conservation agriculture improves soil ...
Bacterial diversity as affected by tillage practice in a raised bed planting system
Carbon and nitrogen dynamics are altered by tillage so it was hypothesized that the composition of the microbial population that control these processes was affected too. Soil was sampled from conventional beds (CB) tilled ...
The effect of different tillage and residue management practices on soil characteristics, inorganic N dynamics and emissions of N2O, CO2 and CH4 in the central highlands of Mexico: a laboratory study
Conservation agriculture in its version of permanent raised bed planting with crop residue retention increases yields and improves soil characteristics, e.g. aggregate distribution, organic matter content, so it remained ...
