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 ...
Soil quality as affected by tillage-residue management in a wheat-maize irrigated bed planting system
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 ...
Soil water content, maize yield and its stability as affected by tillage and crop residue management in rainfed semi-arid highlands
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 ...
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 ...
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 ...
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
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 ...
