Effect of phosphorus form on short-term solubility and availability in soils
A laboratory experiment was set up to compare solubility and “availability” of four phosphate fertilizer sources over a period of 32 d after application to soils with varying pH levels. Three soils, one acidic and two ...
Nitrogen, phosphorus, and rhizobial strain responses of lentil
Three field experiments were set out in 1987 to test the effect of nitrogen fertilizer, phosphorus fertilizer, and rhizobial strain on lentil yields and N2 fixation. The following treatments were laid out in a split-split-plot ...
Phosphorus status of a soil in a long-term experiment
An experiment that was established in 1982 to assess placement of P fertilizer on the yield of continuous barley was terminated in 2004, after annual application of P (30 kg ha-1) was discontinued in all but one treatment ...
Accounting of nitrogen levels in Saskatchewan soils
Yield of PB50 inoculated and phosphorus fertilized wheat
Four locations in the Brown (Leader, Sceptre, Kindersley, and Gull Lake), two in the Dark Brown (Regina and Outlook (irrigated)), five in the Black (Blaine Lake, Dubuc, Glenavon, Langbank, and Star City), and two in the ...
Soil fertility issues
In 1991, the Saskatchewan soil testing laboratory established programs to address some of the concerns and questions raised by producers. With the cooperation of fertilizer dealers, the lab established 12 strip trials on ...
Agronomic and economic benefits of fertilizing crops
Operating costs at farm level can be divided into essential, enhancement, maintenance, protection and insurance. Save growth hormones, which are not common in western Canada, fertilizer and better quality of seed are the ...
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 ...
