UGFERTEX
Version 3.0

NOTICE: UGFertex is based on the University of Georgia soil testing program and is correlated with the Mehlich I soil test extractant. Soil test inputs using other extractants may cause invalid results. Unrealistic yield goals or excessive P and K buildup rates also may not be economically feasible.

This program is based on the best available data. Since many uncontrolled variables can affect plant growth and nutrient requirements, the University of Georgia Cooperative Extension Service is not responsible for any losses incurred from the use of this program. This software is provided "AS IS" and without warranty as to performance.
