Title: Crop Nutrient Removals vs. Fertilizer Additions in North Dakota
Author: Johnson, A.; Swenson, L.J.; Dahnke, W. C.
Description: The article concerns both the attrition of soil nutrients and the replacement thereof. Soils inherently contain only a finite quantity of nutrients. When more nutrients are removed than are being replaced, soil eventually becomes depleted. Data from a study in this paper indicated that in North Dakota, plant nutrients are not being replaced in quantities large enough to replace all of the nutrients being removed by crops.
