The effect of organic fertilizers of buckwheat husk and straw on the growth of European pine seedlings

The article presents the results of pilot production studies that have been conducted since 2022 at the Dmitrov forest nursery on the use of organic fertilizers buckwheat husk and straw when growing European pine. During production studies, we laid down various options for the use of mineral and organic fertilizers in 2022. The dynamics of the chemical composition of the soil was revealed in the options: without the use of mineral fertilizers and with the use of organic fertilizers (buckwheat husk and straw), at the beginning and at the end of the growing season, as well as by year of study. Production studies have shown the effectiveness of using organic fertilizers along with the use of mineral fertilizers, while there was a significant saving of the latter, and the activation of anaerobic processes when using organic fertilizers. The use of organic fertilizers revealed: soil porosity improves; the looseness of the soil increases due to the fact that organic fertilizers create an air layer, which accelerates anaerobic processes in the soil and, as a result, difficult-to-dissolve nutrients in the soil pass into easily digestible forms. The article shows that seedlings grow faster due to the acceleration of seedling growth due to the formation and retention of soil gases in the upper soil layer. The article also notes that the use of organic fertilizers allows you to get organic products, which have been in demand in recent years. The use of organic fertilizers allows you to increase stress resistance due to the formation of a kind of air cushion in the upper soil layer. The authors substantiate the conclusion about the prospects of using organic fertilizers and continuing research in this direction.
