This study compares the effect of lime additions on the spatial variability of Fe, Mn and Zn extracted by Mehlich-1 during three different growth stages from an acid paddy soil, a Typic Plintacualf, in Corrientes, Argentina. Field trials were set up involving three treatments: control, without lime addition, plus two different dolomite doses of 625 and

Increasing number of soil testing laboratories in the mid-Atlantic and southeastern states of the United States are adopting Mehlich-3 (M-3) as the official extraction procedure in place of Mehlich-1 (M-1) or the dilute double acid method. Several studies have indicated that the M-3 has at least equivalent if not better extractability, particularly of ...

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.
