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).

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.

DEVELOPMENT OF A CRITICAL MEHLICH 3 SOIL ZINC CONCENTRATION FOR RICE IN ARKANSAS
Communications in Soil Science and Plant Analysis, 2002Zinc (Zn) fertilizer recommendations for rice (Oryza sativa L.) in Arkansas have been based on soil pH since the 1970s and have not accounted for the residual carryover of previous Zn fertilizer applications. Continuous application of Zn fertilizer to soil in some fields cropped to rice has resulted in very high Mehlich 3 extractable Zn (M3Zn ...

Journal of Environmental Quality, 2006
ABSTRACTThere is a lack of information on how fertilization and initial Mehlich‐3 phosphorus (M3P) interact to affect water soluble P (WSP) in soils. Our objectives were to (i) quantify the relationship between WSP and M3P for four textural diverse benchmark soils of North Carolina (NC) and (ii) quantify the change in WSP concentrations following P ...

Effects of tillage, lime, and phosphorus on soil pH and mehlich‐3 extractable nutrients
Communications in Soil Science and Plant Analysis, 1994In Eastern Canada, barley yields are often restricted by soil acidity and low fertility as well as by structural degradation.

Creeping Bentgrass Putting Green Mehlich‐3 Soil Test Phosphorus Requirements
Crop Science, 2012ABSTRACTThe Mehlich‐3 soil test is extensively used to determine available soil P; however, calibration studies for sand greens are lacking. The purpose of this field study was to evaluate turfgrass response to different soil test P (STP) levels and application of trinexapac‐ethyl (TE) (0.1 kg a.i. ha−1 every 200 growing degree days).

Impact of Soil Temperature and Moisture on Mehlich-3 and Morgan Soil Test Phosphorus
Soil Science, 2010Guidance for timing of sampling is seldom included in soil sampling protocols for agronomic phosphorus (P) fertilizer recommendations or P runoff risk assessment. Our objectives were to determine the influence of soil temperature and moisture content on (i) Mehlich-3 and Morgan soil test P (STP) levels and (ii) the accuracy of Mehlich-3 to Morgan STP ...

THE LANCASTER SOIL TEST METHOD AS AN ALTERNATIVE TO THE MEHLICH 3 SOIL TEST METHOD1
Soil Science, 2001A study was conducted to compare and correlate the Mehlich 3 soil extraction method with the Lancaster soil extraction method. This study compared calcium (Ca), magnesium (Mg), potassium (K), and phosphorus (P) concentrations in 422 soil samples from eight fields, which varied greatly in soil type, texture, and fertility.
