ASSESSMENT OF WASTE OF ALCOHOL INDUSTRY (FUGAT) APPLICATION FOR AGRICULTURE
The results of a growing experiment on assessing the possibility of using the waste from the alcohol industry (fugat) as fertilizer for winter rye grown on green mass are presented. The experiment was carried out in 2015-2017, Moskovskaya 15 variety was grown. The soil is light gray forest loamy with low humus content, high content of mobile phosphorus and average content of mobile potassium, slightly acidic. The fugat in its natural state has a high humidity (96%), an acidic reaction (pH 4.1), a low content of nitrogen, phosphorus and potassium - 0.12, 0.07 and 0.06%, respectively, based on natural humidity. The neutralization of the acidity of the fugat was carried out with KOH and NH4OH solutions; the pH of the fugat after neutralization was 6.8 units. We studied the effectiveness of root and non-root (foliar) top dressing with a fresh fugat according to the background of introducing the fugat of the long-term storage in the entire soil mass of the vessel. It was established that root top dressing with a fresh fugat with an initial pH value had a significant positive effect on the yield of winter rye phytomass, estimated at 35%. At the same time, neutralization of the acidity of the fugat did not give an additional effect, showing only a tendency to increase yields. Foliar top dressing with a neutralized fugat led to inhibition of plants and a decrease in productivity. To eliminate the specific odor of the fugat, it is possible to use lime together with ferric chloride, used as a coagulant at a dose of 10-20% CaO and 3-5% FeCl3 from the mass of the fugat.
