dc.description Due to North Dakota's economic dependence in the exportation of it's agricultural products, farm lands face the continual attrition of minerals that support agriculture. 70 % of the crops grown in North Dakota in 1986 were that of small grains. The production of sunflowers increased from 120,000 acres in 1971 to over a million in 1986. Approximately, 17% of crop land at the same time was used for hay production which is used for cattle feed. A portion of those nutrients consumed by cattle are returned to the state though manure. The remaining 9% of the crop lands are used for flax, beets, corn, potatoes and bean production. Those nutrients most depleted from farm land are phosphorous, nitrogen and potassium. Wheat depletes about 50% of the potassium and nitrogen in crop lands. The remainder of this article breaks down it's discussion into three areas: potassium, nitrogen and phosphorous depletion and supplementation. A deficit of these 3 addressed nutrients occurs when more is going out than being replaced. A systematic testing of soils for these elements helps better maintain proper nutrient levels for a more maximized crop yield.
