Conservation agriculture and soil carbon sequestration: between myth and farmer reality
(2009)
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 ...
Article
Using NDVI and soil quality analysis to assess influence of agronomic management on within-plot spatial variability and factors limiting production
(2009)
Crop growth and yield are the result of the efficiency of the chosen agricultural management system within the boundaries of the agro-ecological environment. Linking spatial variability in crop performance to differences ...

The natural abundance of 13C with different agricultural management by NIRS with fibre optic probe technology
(2009)
In the present study the natural abundance of 13C is quantified in agricultural soils in Mexico which have been submitted to different agronomic practices, zero and conventional tillage, retention of crop residues (with ...
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 ...
Article
Straw management, crop rotation, and nitrogen source effect on wheat grain yield and nitrogen use efficiency
(2008)
Nitrogen fertilizer management from different sources and annual crop rotations are important components of wheat (Triticum aestivum L.) production systems, especially where air and soil quality issues have prompted a ...
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 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
Evaluating spatial within plot crop variability for different management practices with an optical sensor?
(2007)
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 ...
