PERLHUMUS® Granules is a granulated high quality natural humic acid/ humic substances soil conditioner and chelator based on German Leonardite.

The special advantages of PERLHUMUS® Granules as a soil conditioner are its positive influence on plant growth and the improved resistance of plants against stress factors (drought, salinity, and pesticides). It increases the soil cation exchange capacity and soil buffering capacity as well as the soil water holding capacity.
The positive effect of PERLHUMUS® Granules on soil life, soil structure and the rhizosphere can be seen after the first application. PERLHUMUS® Granules can be used in a wide variety of applications and should be applied to the ground using non-hygroscopic equipment.
