Long-term consequences of tillage, residue management, and crop rotation on selected soil micro-flora groups in the subtropical highlands
Densely populated and intensively cropped, the subtropical highlands of the world have agricultural sustainability problems resulting from soil erosion and fertility decline. In 1991, the International Maize andWheat ...
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 ...
Aggregation and C and N contents of soil organic matter fractions in a permanent raised-bed planting system in the highlands of Central Mexico
Permanent raised bed planting with crop residue retention is a form of conservation agriculture that has been proposed as an alternative to conventional tillage for wheat production systems in the Central Highlands of ...
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 ...
Evaluating spatial within plot crop variability for different management practices with an optical sensor?
It is essential to have an indication of the sustainability of an agricultural system in addition to the potential, immediate benefits well before the catastrophic consequences of non-sustainability become apparent. Long-term ...
