Title: Potash and Phosphate Fertilization on Irrigated Alfalfa
Author: Thompson, C.R.; Dodds, D.L.; Hoag, B.K.
Description: From 1983-86, North Dakota had approximately 210,000 irrigated acres annually. 65-70,000 acres were hay lands. Alfalfa was one of the more profitable crops grown in the state under irrigation due to the short growing season and cool climate. Alfalfa does not respond to surface broadcast potash and phosphate andtend to stay on the soil. In this article, a study is outlined/ It was initiated to determine the effects of potash and phosphate fertilization on alfalfa production and it's economic profitability. The methods are presented. The results and discussion follow. The results of this study indicated that producers must test the soil and apply the potash and phosphate to maximize yields of aging alfalfa stands on irrigated course textured, sandy soils. Maintenance of the proper levels is key.
