Seasonal fluctuations of N2O emission in different soil landscape systems
Nitrous oxide has been widely recognized as a major scientific and environmental ‘issue because of its involvement in global warming and destruction of the atmospheric ozone layer. The inherently high temporal and spatial ...
Nitrogen cycling in an alfalfa-bromegrass sward
Calibration of bicarbonate-extractable phosphorus on wheat
Nine locations were selected throughout Saskatchewan so that a summerfallow an oilseed stubble and a wheat stubble experimental site were adjacent to each other. Each site was characterized by analyses carried out on a ...
Contribution of hay harvest losses and "leaf fall" to N cycling and the N nutrition of intercropped alfalfa and bromegrass
A significant amount of forage plant biomass is deposited on the ground as senescent leaves, petioles and flowers (leaf fall). In addition, a varying amount of plant biomass is lost during harvest of hay crops (hay loss). ...
Evaluation of Penicillium bilaji inoculation and copper and zinc fertilization in relation to crop yield and nutrient uptake
Growth chamber and field experiments were conducted on three low micronutrient alkaline soils from Northeastern Saskatchewan to test the efficacy of PB-50 inoculation and phosphorus (P), copper (Cu) and zinc (Zn) fertilization ...
Response of irrigated crops to split-N application
The efficiency and benefits of split N applications by cereals and oilseed was evaluated at the Irrigation Fann at Outlook. In 1988, canola (Westar) received 0, 75 + 75, or 150 kg N/ha in the form of urea (U) or urea-ammonium ...
Penicillium bilaji (PB50) and phosphorus fertilizer responses of yield of wheat and barley grown on stubble and summerfallow
At nine locations, selected throughout the Brown, Dark Brown and Black Soil Zones, wheat and barley were grown on summerfallow (9 locations), cereal (8 locations) and oilseed stubble (6 locations). In total, 46 experimental ...
Dual inoculation of Pisum sativum with Rhizobium leguminosarum and Penicillium bilaji
To investigate the effect of single versus dual inoculation of Trapper-pea with Rhizobium leguminosarum and Penicillium bilaji, a P-solubilizing fungi, an experiment under controlled conditions was carried out using a sandy ...
Does crop residue N influence soil N availability?
A landscape study was conducted near Biggar, Saskatchewan, to study the influence of crop residues on the availability of soil N in the second phase of crop rotations. In order to compare leguminous and cereal residues, ...
