EFFECT OF THE "PEATGEL" HUMIC PREPARATION ON THE AGROCHEMICAL PROPERTIES OF THE SOIL, THE OAT CROPS, AND THEIR QUALITY

The article presents the results of a field experiment on the effect of the humic preparation Peatgel on the agrochemical properties of sod-podzolic soil, the biometric indicators of crop growth and development, the yield, and the quality of the grain and straw. It was found that the humic preparation had a slight positive effect on increasing the organic matter content in the experimental soil, compared to the control and the mineral fertilizer option. Under the influence of humate, the field germination of oat seeds, the preservation of plants by harvesting, and linear growth increased slightly compared to the control. The effect of humate on grain and straw yield was weaker than that of fertilizers. Fertilizers had a stronger effect on increasing the “crude protein” content in grain compared to humate. The lowest “crude protein” content in grain was observed in the control. Humate had a more positive effect on the quality of straw and its nutritional value than mineral fertilizers.
