Soil Fertility Testing

This program is designed as a soil-management tool for farmers, homeowners, landscape contractors, golf-course superintendents, ornamental nurserymen and others interested in the fertility of their soil and in determining the optimum lime and fertilizer requirements of their crop.

Each sample is analyzed for water pH, Mehlich buffer lime requirement, and for phosphorus, potassium, magnesium, and calcium by the Mehlich 3 (ICP) test. The final report includes the chemical analysis of the soil along with lime and fertilizer recommendations for the crop specified. For agronomic crops, Mehlich 3 zinc, copper and sulfur are also reported.
