Influence of Different Methods of Application of Lignogumate on the Product Quality of Green Crops and Medicinal Plants

Abstract

The effectiveness of the use of lignohumate on lettuce (annual, green crop) and peppermint (perennial, medicinal plant) grown under the conditions of vegetation experiments was studied. The combination of lignohumate with the introduction of chelated fertilizers containing trace elements (zinc, copper) into peat showed a significant positive effect in obtaining high-quality plant products. The most effective was the fertilizer system, which included a combination of lignohumate with chelated forms of zinc and copper: the increase in lettuce biomass was 29–32, mint – 71–79%, the content of macroand microelements in plants became optimal.
