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 ...
Microbial biomass C measurements in soil of the central highlands of Mexico
Microbial biomass is the key factor in nutrient dynamics in soil, but no information exist about it in soils of the central highlandsof Mexico, a major agricultural area.We determined the microbial biomass in soils with a ...
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 ...
NIR spectroscopy: An alternative for soil analysis
Advances in laboratory instrumentation and chemometrics provide alternatives to traditional methods of conducting soil chemical analysis. One of these is infrared diffuse reflectance spectroscopy in the near-infrared ...
Wheat yield and tillage-straw management system year interaction explained by climatic co-variables for an irrigated bed planting system in northwestern Mexico
Wheat is an important food and income source and estimated demand for wheat in the developing world is projected to increase substantially. The objectives of this study were to gain insight into (i) the effect of tillage?straw ...
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 ...
