Fertilizer management for seed production of perennial forage crops in the Canadian Great Plains

摘要：

In the Canadian prairies, nitrogen (N) and phosphorus (P) are most commonly deficient nutrients, while potassium (K) and sulphur (S) may also be deficient for certain crop and soil conditions.One or more of these four major nutrients may be limiting for optimum forage seed yield.Perennial forages respond well to the application of fertilizers on nutrient deficient soils.The purpose of this report is to summarize research information on fertilizer management for improving seed production of perennial forages in the Canadian Great Plains.
