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 ...
Conservation agriculture and soil carbon sequestration: between myth and farmer reality
Improving food security, environmental preservation and enhancing livelihood should be the main targets of the innovators of today's farming systems. Conservation agriculture (CA), based on minimum tillage, crop residue ...
Conservation agriculture as a sustainable option for the central Mexican highlands
Tropical highlands of the world are densely populated and intensively cropped. Agricultural sustainability problems resulting from soil erosion and fertility decline have arisen all over this agro-ecological zone. Based ...
Conservation agriculture, increased organic carbon in the top-soil macro-aggregates and reduced soil CO2 emissions
Background and aims: Conservation agriculture, the combination of minimal soil movement (zero or reduced tillage), crop residue retention and crop rotation, might have the potential to increase soil organic C content and ...
Influence of permanent raised bed planting and residue management on physical and chemical soil quality in rain fed maize/wheat systems
Densely populated, intensively cropped highland areas in the tropics and subtropics are prone to erosion and declining soil fertility, making agriculture unsustainable. Conservation agriculture in its version of permanent ...
