Potato Fertilization

Abstract

Results from experiments with varying levels of nitrogen, phosphorus and potassium have shown that the ratios of 1 - 2.5 - 0 to 1 - 3 - 0 produce the highest yields. While the ratio between nitrogen and phosphorus appears important, the water solubility of the phosphorus seems to be the most important factor in proper fertilization. Proper placement of the fertilizer as well as irrigation and other cultural practices are musts in potato production.
