UT Soil & Nutrient Management Website!

Overview

“We do not inherit the land from our ancestors but, we borrow it for our children”

The purpose of UT Soil & Nutrient Management Extension program is to develop and deliver a nationally-recognized county-based Extension and applied research program focused on soil and nutrient management technologies and recommendations for efficient no-till, row-crop, forage and horticultural production in Tennessee. This website addresses the soil fertility needs of Tennesseans using research-based information.
