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, ...
What happens to the soil organic matter if I till long-term no-till?
The long-term practice of no-till (low-disturbance direct seeding) is an effective method to increase the soil organic matter (SOM) content of the soil. If that increased soil organic matter is traded as an offset for ...
25 years of tillage effects on wheat production in a continuous cropping system
Heat stress occurs often in wheat on the Canadian Prairies especially during grain growth (from anthesis to maturity), which has a markedly negative impact on yield (McCaig 1997). Under no-till management (NT), surface ...
Influence of pulse crops on abundance of arbuscular mycorrhizal fungi in a durum-based cropping system
Pulses are an important component in crop rotations in southern Saskatchewan. Besides their capability to fix nitrogen, pulse crops establish a strong symbiotic relationship with arbuscular mycorrhizal (AM) fungi, which ...
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 ...
