Usefulness of Mehlich-3 test in the monitoring of phosphorus dispersion from Polish arable soils. [PDF]

Environ Monit Assess, 2018
A considerable area of soils with low abundance of plant-available phosphorus and relatively low consumption of phosphorus fertilisers recorded in Poland over the last 20-25 years suggests that the dispersion of phosphates from arable soils in Poland can be low.

Site-Specific Mehlich 3-P Recommendations for Florida’s Sandy Soils

Communications in Soil Science and Plant Analysis
In 2010, the Mehlich 3 (M3) soil extractant replaced Mehlich 1 (M1) as the official soil test for Florida. While a linear expression was initially established to reasonably estimate M3-P values based on M1-P recommendations for acid-mineral soils in Florida, Florida farmers have been skeptical of revised P recommendations and reported lower yields when

A Discussion on Mehlich-3 Phosphorus Extraction from the Perspective of Governing Chemical Reactions and Phases: Impact of Soil pH

Agriculture (Switzerland), 2018
Mehlich-3 (M3) is one of the most common agronomic and environmental phosphorus (P) extractants for determining P fertilizer requirements and the potential for non-point source pollution.

Soil texture and organic matter prediction using Mehlich‐3 extractable nutrients

Agrosystems, Geosciences & Environment
Soil organic matter (SOM) and texture are key properties influencing soil nutrient and water dynamics but are time‐consuming procedures for analytical laboratories.

Interlaboratory Validation of the Mehlich 3 Method as a Universal Extractant for Plant Nutrients [PDF]

Journal of AOAC INTERNATIONAL, 2009
Abstract The Mehlich 3 (M3) method is widely used to extract plant-available phosphorus from soil over a wide range of pH values. The method is also used by many laboratories to determine multiple plant-available nutrients simultaneously.

Interlaboratory Validation of the Mehlich 3 Method for Extraction of Plant-Available Phosphorus [PDF]

Journal of AOAC INTERNATIONAL, 2009
Abstract The Mehlich 3 (M3) method is widely used for extraction of plant-available phosphorus (P) from soil over a wide range of pH values. The method is also used by many laboratories to determine multiple plant-available nutrients simultaneously.

Interpretação de resultados analíticos de fósforo pelos extratores Mehlich-1 e Mehlich-3 em solos do Rio Grande do Sul Interpretation of the avalilabre phosphorus by Mehlich-1 and Mehlich-3 extractant solution in soils of the Rio Grande do Sul State, Brazil

Revista Brasileira de Ciência do Solo, 2008
As soluções extratoras multielementares possibilitam avaliar a disponibilidade de vários nutrientes de plantas no mesmo extrato; dentre estes o P merece especial atenção. As soluções Mehlich-1 (M1) e Mehlich-3 (M3) enquadram-se nesta categoria.

Evaluation of Mehlich‐3 for determination of cation exchange capacity in Kansas soils [PDF]

Soil Science Society of America Journal, 2021
Abstract Soil testing laboratories across the United States have implemented the Mehlich‐3 (M3) extraction method for phosphorus (P) and other nutrients. Though M3 is known to work well as a multinutrient extractant, it raises concerns for measuring exchangeable cations, particularly in calcareous soils.
