Boron extraction and vertical mobility in Paraná State oxisol, Brazil Extração e mobilidade vertical de boro em latossolo vermelho eutroférrico no Estado do Paraná [PDF]
Revista Brasileira de Ciência do Solo, 2009 The deficiency or excess of micronutrients has been determined by analyses of soil and plant tissue. In Brazil, the lack of studies that would define and standardize extraction and determination methods, as well as lack of correlation and calibration ...

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 AnalysisIn 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

Do we properly quantify P from Mehlich 1 or Mehlich 3 extracting solutions?
, 2022 Abstract Aims The performance of colorimetric methods for P quantification is usually overlooked by researchers and not suitable to errors. Here, we investigated the performance of two blue colorimetric methods for P quantification, Braga & Defelipo (1974) (B&D) and Murphy & Riley (1962) (M&R), using two commonly soil P ...
