The influence of liquid humic biological means on the growth and development of potatoes

Liquid humic biological means are widely used in plant growing for seed treatment, for root and foliar fertilizing of agricultural plants. In All-Russian Research Institute of Reclaimed Lands developed a liquid humic biological means, whose composition is characterized by the presence of humic acids - not less than 5 g/l, potassium humates - not less than 20 g/l, a set of macro- and microelements, pH - not more than 10. The purpose of the work performed was to study the effect of liquid humic biological means on the growth and development of potatoes as a result of processing tubers before planting. The results of laboratory and field experiments conducted in 2017-2018 are presented. According to the results of a laboratory experiment, the most effective 10% concentration of the working solution of a humic biological means for the treatment of potato tubers before planting was determined. In the small-scale experiment with potatoes, three concentrations (0,5%; 2,0% and 10%) of the humic biological means were used to treat seed...
