Interpreting Mehlich 1 and 3 Soil Test Extractant Results for P and K in Tennessee
2009The Mehlich 1 and 3 soil test extractants are the most widely used in laboratories of the southern United States today. Tennessee began using the Mehlich 1 extractant in December, 1981. Existing soil test calibration data in Tennessee are based on the Mehlich 1 soil test extractant,1,2 which became available in 1953.

Converting Between Mehlich 1 and 3 Soil Test Values for West Tennessee Soils
This publication provides information on the relationship between Mehlich 1 and 3 soil tests (phosphorus) P and (potassium) K for West Tennessee soils. This will allow producers to use the fertilizer recommendations from The University of Tennessee even if they send their samples to a lab using Mehlich 3.Nutifafa Adotey +9 more

Abstract For two soil types, loamy degraded chernozem and silty loam, the conversion equations for phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg) determined after extraction with Mehlich 1‐, 2‐, and 3‐, and CaCl2‐extractants, for K after extraction according to Schachtschabel‐, and P according to Egner‐, Bray‐, and Olsen‐methods were ...

The response of maize (Zea mays L.) variety TZSR-Y grown on soils collected from thirty (30) 1 different locations in northern Nigeria to applied zinc fertilization was examined in two screenhouse pot experiments. The Mehlich I extractable soil zinc (Zn) ranged from 0.6 to 4.1 mgkg-1 with a mean of 2.00 mgkg-1.

Abstract The Mehlich 3 (M3) extractant was introduced in 1981 to improve the efficiency of soil testing laboratories by eliminating the need for multiple extractants for P, K, Ca, Mg, Mn, Cu and Zn. The M3 was also intended to be suitable for a wide range of soils, perhaps to serve as a “universal”; soil test extractant.
