Seasonal variation in the soil microbial community in wheat-growing soil and influence of C, N, and P inputs
It has long been know that N and P fertilization increases plant growth and yield, but the impact of fertilization on soil microorganisms has rarely been considered. Long-term plots (36-year old) under fallow-wheat-wheat ...
Microbial community structure under various wheat-based cropping systems
The effects of cropping systems on soil biological quality are slow to develop. We sampled the soil of a 36-year old long-term experiment established on an Orthic Brown Chernozem, at Swift Current SK, in the fall of 2003, ...
Yield and protein of wheat and durum in Brown Soil Zone as affected by long-term tillage system and crop rotation
Three tillage-rotation experiments in the Brown soil zone showed that spring wheat and durum grain yield and protein were affected by tillage system, length of time in tillage system, crop sequence. During the initial 15 ...
Effect of cropping frequency, wheat classes, and flexible rotations on yield, production, and nitrogen economy in a Brown Chernozem
Producers in the semiarid Canadian prairies frequently summerfallow (F) to conserve water, control weeds, and to maximize soil N reserves; however, this practice often results in soil degradation. A crop rotation experiment ...
Relationship between soil texture and soil organic carbon at small field scale
The capacity of a soil to store organic carbon is related to its particle size distribution, or soil texture, mainly because the capacity of clay particles to stabilize organic materials. A study of the relationship of ...
