INFLUENCE OF HUMATE OF POTASSIUM OF DIFFERENT CONCENTRATION ON THE EFFICIENCY OF MINERAL FERTILIZERS WHEN GROWING OAT

In a field experiment, they studied the effect of non-root fertilizingwith potassium humate of various concentrations on yield, chemical compositionand extraction of nutrients by oats, as well as on the agronomic andphysiological effectiveness of fertilizers. It is shown that when spraying oatplants with potassium humate at the end of tillering stage –the beginning of the release into the tube, the total biomass increases,including the grain yield. Nitrogen and potassium from fertilizers were mostefficiently consumed by plants with foliar feeding with potassium humate at aconcentration of 0.30 %, applied nitrogen was used at 92 %,and potassium at 82 %. An increase in the concentration of humate in the foliarapplication somewhat reduced fertilizer efficiency. Foliar nutrition of oatswith potassium humate increases the payment for a unit of fertilizer withgrain. The highest return on fertilizer was obtained with a humateconcentration of 0.30 % – 20.4 g/g. Theconsumption of nutrients during the creation of a unit of yield of 1g of grainwith additional feeding with a concentration of potassium humate 0.15 %:amounted to 11 g of nitrogen, 35 gof phosphorus and 20 g of potassium. With an increase in concentration, theextraction of nutrients into a unit of production decreases, which indicates amore rational use of the absorbed nutrient. The degree of utilization ofnutrients applied with fertilizers, estimated by the coefficient of absorptionefficiency (CEP), demonstrated that nitrogen and potassium from the fertilizerswere most efficiently consumed by plants with foliar top dressing withpotassium humate at a concentration of 0.30 %:potassium by 82 %.
