Evaluation of Mehlich 3 reagent as a multielement extractant in mine soils
Land Degradation and Development, 1999The usefulness of Mehlich 3 (M3) reagent was evaluated as a method to extract numerous elements from coalmine soils in As Pontes (Spain) showing a wide range of physicochemical properties. Critical levels (deficiency and/or toxicity) were established for plant available elements extracted by this reagent. The M3 method was compared to 1M NH

Mehlich 3 Soil Phosphorus as Determined by Colorimetry and Inductively Coupled Plasma
Communications in Soil Science and Plant Analysis, 2009Inductively coupled plasma (ICP) emission spectroscopy is routinely used in laboratory testing to determine soil P extracted by Mehlich 3 (M3P). The effectiveness of ICP, however, has been questioned, particularly when used to detect soil P. Our objective was to compare ICP (M3P‐ICP) with colorimetric (M3P‐Col) methods of determining soil M3P.

Mehlich 3 soil test extractant: A modification of Mehlich 2 extractant
Communications in Soil Science and Plant Analysis, 1984Abstract The objectives of this study were to modify the Mehlich 2 (M2) extractant to include Cu among the extractable nutrients, retain or enhance the wide range of soils for which it is suitable and minimize it's corrosive properties. The substitution of nitrate for chloride anions and the addition of EDTA accomplished those objectives.

Evaluation of Mehlich 3 as a Universal Nutrient Extractant for Australian Sugarcane Soils
Communications in Soil Science and Plant Analysis, 2012This study evaluated the suitability of the Mehlic h3 universal extractant as a part of a multielement test to assess the nutrient status of Australian sugarcane soils. Soil samples from BSES Soil Exchange Programs, representing all major soil types and geographic sugarcane-growing regions, were analyzed using existing BSES, acid-based extraction ...

ABSTRACTAccurate soil testing procedures contribute to agricultural development of Mozambique. The Mehlich 3 (M-3) procedure has not been evaluated for Mozambican soils despite its wide applicability. Results showed M-3 solution could extract exchangeable calcium (Ca), magnesium (Mg), and potassium (K) as well as 1 M ammonium acetate (NH4OAc), while M ...

Soil phosphorus content determined by Mehlich 3 and modified Mehlich 3 methods
2023During the last century multiple methods have been developed for the determination of the amount of plant available nutrient elements in the soil. One of the critical nutrient elements in soil is phosphorus. Most of the phosphorus exists in soil in the form of insoluble inorganic and organic compounds.

Mehlich‐3 phosphorus buffer coefficients
Communications in Soil Science and Plant Analysis, 1998Abstract Phosphorus (P) fertilizer recommendations can be improved if the amount of P required to raise the soil test to a desired value is known. The objective of this study was to determine the increase in soil test P per unit of applied P, the P buffer coefficient, in the laboratory by various means and to compare those values with P buffer ...
