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.

Pre-Sidedress Nitrate Test for Corn (PSNT)

The Pre-Sidedress Nitrate Test is a soil nitrogen test that is designed to provide assistance in making agronomically and environmentally sound nitrogen recommendations for corn. The PSNT is especially useful in systems where manure has been applied because it eliminates some of the uncertainty associated with utilizing manure N.

Particle Size and Sand Sieve Test

These tests are designed for landscape architects, golf course superintendents, municipal park managers, and those who supply sand, soil, and other mixtures used by these professionals in maintenance and construction activities.

Environmental Soil Testing

The tests described are designed to assist municipalities, farmers, environmental agencies, and others in developing environmentally sound soil management programs. These tests for major and trace elements assist in monitoring soils that have been amended with biosolids or other materials.

Aluminum Stress Test

The test is used to evaluate the potential stress of aluminum (Al) on forest tree species when grown on soils with pH less than 5.5. The aluminum stress test is designed to assist homeowners, park managers and others in optimizing woodlot management.
