Global warming potential of agricultural systems with contrasting tillage and residue management in the central highlands of Mexico
(2012)
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 ...
Article
Greenhouse gas emissions under conservation agriculture compared to traditional cultivation of maize in the central highlands of Mexico
(2012)
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 ...
Article
Soil water content, maize yield and its stability as affected by tillage and crop residue management in rainfed semi-arid highlands
(2011)
Rainfed crop management systems need to be optimized to provide more resilient options to cope with projected climatic scenarios forecasting a decrease in mean precipitation and more frequent extreme drought periods in ...
Article
Long-term consequences of tillage, residue management, and crop rotation on selected soil micro-flora groups in the subtropical highlands
(2008)
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 ...

Article
Soil quality as affected by tillage-residue management in a wheat-maize irrigated bed planting system
(2011)
There is a clear need to develop conservation agriculture technologies appropriate for surface irrigated conditions, and the adoption by small-scale farmers. The objective of this paper is to evaluate the effect on soil ...
Article
Molecular characterization of soil bacterial communities in contrasting zero tillage systems
(2010)
It is well known that agricultural practices change the physical and chemical characteristics of soil. As a result, microbial populations can also be affected. The aim of this study was to analyze the effect on soil bacterial ...
Article
Aggregation and C and N contents of soil organic matter fractions in a permanent raised-bed planting system in the highlands of Central Mexico
(2008)
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 ...
Article
Long-term consequences of tillage residue management and crop rotation on maize wheat root rot and nematode populations in subtropical highlands
(2006)
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 ...
Article
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
(2009)
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 ...
