P and K fertilizer nutrients in forage crops

Only about 15% of the alfalfa grown in western Canada is fertilized annually, and generally with low rates of P. Therefore, P and K are often inadequate to produce the most economic yield. This projects investigates P and K applications to improve alfalfa yield and quality.

IPNI-1989-CAN-MB3

Two research sites were selected in 1989. The first was a Marringhurst sandy loam soil near Branson and the second a Newdale clay loam soil, near Newdale, MB. Each site had been sown to Algonquin alfalfa three years previously and had been cut for two years. Neither had been fertilized in the previous year. Uniform areas were selected for the experimental site. Read more
