Description

Meadow red clover (Trifolium pratense sponta­neum) was found to be suitable for testing the site-specific Mn, Zn, Cu, and Mo status of soils under permanent grassland, which depends on the geological origin of the parent rock. The Mn, Zn, Cu, and Mo levels of meadow red clover proved to be correlated with the level of these microelements in field red clover and in the black hair of cows grazed on the same sites. By means of this indicator method, Mn and Cu deficiency and Mo excess areas were detected.
