Меры по стабилизации роста и урожайности овощных культур в долгосрочных вегетационных опытах с удобрениями

Abstract

In long-range vegetation experiments performed on solanaceae (tomatoes, peppers), the intensive growth and productivity of the first year is gradually reduced during the following years, the number of fruits diminishes and commodity qualities deteriorate, the uptake of nutrient elements by the plant falls, the main reason for which is the exhaustion of the soil, which is connected with the absence of crop rotation and probable deficit of nutrients in the soil. To lessen the above-mentioned negative effects on the plants it is necessary to disinfect the soil substratum with acquatic solution of 0,2% funguran (1 litre to the small pots, 2 litres to big pots) before fertilizing the pots and planting the seedlings every year in spring.
