Farmers must be concerned about both the monetary loss and the threat of groundwater and surface water pollution associated with the loss of plant nutrients from their fields. There is also an increasing public concern about pollution and the role of agriculture in nonpoint-source pollution. Movement of water over the surface of the soil as well as through the soil profile increases the potential for loss of water-soluble nutrients, especially nitrates.

Row fertilizer is an old practice which has been in and out of favor over the years. The use of row fertilizer and its benefits vary with the conditions. The efficiency of applied fertilizer is greatly increased by putting it beside the row and is very helpful on soils with a low soil test. For soils testing medium or high, a sufficient amount of nutrients exist in the soil so that additional fertilizer applied in the row will not increase yields. Regardless of soil test. row fertilizer will usually increase the vigor and early growth of a crop. Most of …
