Soil Testing
The Mississippi State Soil Testing Lab is an Extension unit of the Department of Plant and Soil Sciences. The mission of the Soil Testing Lab is to provide accurate analytical services in a timely manner. With the support of research conducted by MSU faculty members, the Soil Testing Lab provides unbiased nutrient management recommendations. Our lab works closely with County Extension Agents to provide outreach to all Mississippi landowners concerned with improving soil productivity.
The Soil Testing Lab provides the following services:
Soil Test
The soil test represents a vital piece of Mississippi State Extension outreach. If you are interested in improving soil fertility for farming, gardening, lawns or wildlife food plots you should get a soil test! Our analysis includes pH, lime recommendation, phosphorous (P), potassium (K), Calcium (Ca), Magnesium (Mg), Zinc (Zn), and Sodium. Total soluble salts (TSS) are reported for all horticultural samples.

Plant Tissue Analysis
Plant tissue analysis provides a more accurate estimation of essential nutrient concentrations vs. soil analysis. Analysis includes total nitrogen (N), phosphorous (P), potassium (K), Calcium (Ca), Magnesium (Mg), Copper (Cu), Zinc (Zn), Manganese (Mn), Iron (Fe), and Boron (B). Sulfur (S) is available upon request.
Texture Analysis
Sodium hexametaphosphate is used to separate sand, silt, and clay fractions of soil samples which are then evaluated with the hydrometer method.
Total Carbon/Total Nitrogen
This information will be available soon.
