Biomass accumulation and nutrient uptake of oilseeds at different growth stages in the parkland region of Saskatchewan
Field experiments were conducted with canola (Brassica napus and B. rapa, cv. Quantum and Tobin), mustard (cv. AC Vulcan) and flax (cv. Norlin) in 1998 and 1999 at Melfort, Saskatchewan, Canada, to determine biomass and ...
Management for optimum yield of open pollinated and hybrid canola
Newer open pollinated (O.P.) and hybrid canola varieties provide higher yield potential but the management strategies necessary to achieve optimum yield are not well understood. To better understand the levels of inputs ...
Effect of cultivation, tillage practice, and fertilization on total organic carbon, light fraction, and microbial biomass carbon in soils from the Loess Plateau of China and the Canadian prairies
Three soils: Huangmian, Huihe, Heilu soil, from the Loess Plateau and one soil: Orthic Brown Chernozem, from the Canadian Prairies, were used to evaluate the effect of cultivation time, tillage system and fertilization, ...
Soil carbon changes in cultivated land converted to grasses in south-central Saskatchewan
Soils play an important role in the carbon cycle. Under natural conditions, soil organic carbon forms an equilibrium with the environment. Disruption to this equilibrium can transform the soils into either a source or a ...
Potential for wind erosion in alternative cropping systems
The potential for wind erosion in agricultural soils is a function of the distribution of aggregates at the surface, soil structure and moisture, and crop residue. These properties were measured in a cropping systems study ...
