Fertilizer and limestone decisions hinge on results obtained from your sample. A well taken soil sample results in appropriate recommended rates of fertilizer and limestone.
Good soil sampling and analyses can drastically change fertilizer use on a farmer's fields.
One farmer in southwestern Missouri normally applied 50 pounds of phosphate fertilizer per acre, along with other needed nutrients, on his corn and soybeans. Three other fields had tests showing a need for only 35 pounds of phosphate per acre. With those very high soil tests, he won't need phosphate fertilizer for several years and should experience no loss in crop yield potential. Farmers in southeastern Missouri have demonstrated the value of mapping soil fertility on their fields. Samples have been obtained from each 2.5 acre area of the field.
