Abstract
The use of fertilizers in vegetable growing in Russia has always been highly effective, increasing the yield of vegetable crops by 20-40%, and during irrigation - by 1.5-2 times. Chemical ameliorants (lime, gypsum) are also very effective. On acidic soils, NPZ lime optimizes the response of the soil environment and reduces the harmfulness of fungal diseases, and on alkaline soils of the southern regions, the use of gypsum can dramatically reduce the incidence of vegetable plants by bacterial diseases. The combined use of organic, mineral fertilizers in combination with growth regulators and ameliorants in irrigation conditions allows to increase the yield of main crops by 37-71% on alluvial meadow soils of the Moscow region and by 81-136% on ordinary chernozem of the Rostov region, which ensures high profitability of the industry vegetable growing.
