Effect of fertilizer placement on yield of established alfalfa stands

摘要: Alfalfa yield response to P and K fertilization management has been documented elsewhere, but little work done in western Canada. Field studies conducted on two Manitoba soils for 4 yr evaluated the effects of four levels monoammonium phosphate three potassium chloride fertilizers, applied as a surface broadcast or an in-soil band application, established alfalfa (Medicago sativa L.) stands. Applied increased total annual forage clay loam soil by 1.53 t h−1 (47%), when averaged over study, did not increase yields fine sandy loam. Yield application study. Potassium resulted minor no increases both soils. On soil, there was difference between banded fertilizer applications. reduced slightly compared with part...
