Starter fertilizer may increase early growth of corn and grain sorghum. Grain yield increases from starter nutrients are most likely on low phosphorus soils and some sandy soils.
Proper use of a starter fertilizer is an important management tool for crop producers striving for top yields. While the use of a starter fertilizer can be important for crop production on many soils, it is more important for corn production on irrigated sandy soils than on fine textured soils.
