Abstract
Tillage is performed for various reasons. One is to incorporate fertilizers and other soil amendments. Depth of placement and extent of incorporation of these materials is affected by the tillage implement used. Data from two North Dakota locations, where four different tillage treatments were imposed following the uniform application of phosphorus fertilizer on each site, show that turning the soil with a moldboard plow placed more of the fertilizer phosphorus in the 3 to 6-inch depth than where the soil was not tilled or where tillage was done with a double disk or Noble blade. These two different tillage methods are discussed in detail in this article along with conclusions drawn.
