Earthworm activity and soil structural changes under conservation agriculture in central Mexico
Crop residue mulching combined with zero tillage and crop rotation, known as conservation agriculture (CA), is being promoted as an alternative system to revert soil degradation in maize-based farming in the central highlands ...
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 ...
Tillage and residue management effects on soil quality in maize and wheat systems in the highlands of Central Mexico
(CIMMYT / Wageningen University, 2008)
Long-term consequences of tillage residue management and crop rotation on maize wheat root rot and nematode populations in subtropical highlands
Densely populated and intensively cropped, the subtropical highlands of the world have severe agricultural sustainability problems resulting from soil erosion and fertility decline. In 1991, the International Maize and ...
Reduced nitrogen and improved farm income for irrigated spring wheat in the Yaqui Valley, Mexico, using sensor based nitrogen management
Wheat nitrogen-use efficiency in the Yaqui Valley has been estimated at about 0.31. The nitrogen that is not recovered by the crop has important environmental costs that have regional and global consequences. In addition, ...
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 ...
