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.

Sulphur status in agricultural soils determined using the Mehlich 3 method [PDF]

Plant, Soil and Environment, 2018
Several sets of soil samples were chosen to demonstrate the applicability of the Mehlich 3 extractant for the determination of sulphur (S) in soils. Archived samples from 139 basal soil monitoring plots (BSMS) sampled in 1995 and 2013, samples from eleven long-term field trials sampled in 1981 and 2017, 1167 soil samples from the areas vulnerable to S ...

Boron extraction and vertical mobility in Paraná State oxisol, Brazil. [PDF]

Revista Brasileira de Ciência do Solo, 2014
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 ...

Usporedba metoda AA i Mehlich 3 za ekstrakciju kalcija i magnezija iz tala istočne Hrvatske

Poljoprivreda, 2019
Kalcij i magnezij pripadaju skupini zemnoalkalijskih metala značajno zastupljenih u zemljinoj litosferi, odnosno skupini umjereno pokretnih makrohraniva koji imaju važnu ulogu u ishrani bilja. Svrha ovoga istraživanja jest usporedba količine ekstrahiranoga kalcija i magnezija otopinom amonijeva acetata (AA) i otopinom Mehlich 3 (Mehlich 3) iz tala ...

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

Agrosystems, Geosciences & Environment
AbstractSoil organic matter (SOM) and texture are key properties influencing soil nutrient and water dynamics but are time‐consuming procedures for analytical laboratories. Our objective was to evaluate SOM and soil texture predictions using Mehlich‐3 nutrients and pH in Arkansas soils.
