Mehlich 3 extractable nutrients as determined by near-infrared reflectance spectroscopy
Canadian Journal of Soil Science, 2009Near-infrared reflectance spectroscopy (NIRS) is a cost-effective and environmentally friendly technique of soil analysis that is particularly advantageous in intensive soil sampling and soil nutrient management as well. This study evaluated the potential of NIRS for predicting P, K, Ca, Mg, Cu, Zn, Mn, Fe, and Al extracted by Mehlich 3.

Evaluation of the Mehlich 3 soil extractant for upland Malawi soils
Communications in Soil Science and Plant Analysis, 1995Abstract The Mehlich 3 (M3) universal soil extraction method was compared with the ammonium acetate (AA), Bray 1, and DPTA extraction procedures for the analysis of calcium (Ca), magnesium (Mg), potassium (K), phosphorus (P), zinc (Zn), copper (Cu), manganese (Mn), and iron (Fe).

Differences of Phosphorus in Mehlich 3 Extracts Determined by Colorimetric and Spectroscopic Methods
Communications in Soil Science and Plant Analysis, 2005Abstract Mehlich 3 (M3) is a widely used extractant for evaluating plant available phosphorus (P) in soils and may be quantified using colorimetric or inductively coupled plasma (ICP) spectroscopic methods. Analysis by ICP has recently become increasingly popular in soil‐testing labs primarily due to its ability to simultaneously measure multiple ...

Mehlich-3 solution as an extractant for multi-element analysis of soil samples
2023Extraction ability of the Mehlich-3 solution was compared to other two extraction reagents (namely, aqua regia and deionized water) that are more commonly used and cited in the literature. The results show that, despite the weaker extraction power of the Mehlich-3 solution in comparison to aqua regia, the micronutrients Ca, Cu, Fe, K, Mg, Mn, Na, P, S,

Integrating the mehlich‐3 extractant into existing soil test interpretation schemes
Communications in Soil Science and Plant Analysis, 1996Abstract Nutrients were extracted from samples of two Ohio soils derived from Wisconsin‐age glacial till, a Crosby silt loam (Aerie Ochraqualfs, fine, mixed, mesic) and a Hoytville silty clay (Mollic Ochraqualfs, fine, illitic, mesic) using the Mehlich‐3 extractant, and also using Bray‐1 for phosphorus (P) and ammonium acetate (NH4OAc) for potassium (K)

INFLUENCE OF MEHLICH-3 EXTRACTABLE ALUMINUM ON PHOSPHORUS RETENTION IN ORGANIC SOILS
Soil Science, 2008Phosphorus (P) regulations in North Carolina (NC) assume that organic soils have little ability to retain P, and losses of P from these soils are of concern for the health of aquatic ecosystems. However, recent research has indicated decreased water-soluble P (WSP) in organic soils in the presence of high Al concentrations.

Communications in Soil Science and Plant Analysis, 1989
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.
