EFFECTS OF REPEATED CROPS IRRIGATED WITH LOW-MINERALIZED DRAINAGE WATER, FERTILIZER RATES, AND BIOPREPARATIONS ON VOLUMETRIC MASS OF SOIL

In this article, information is provided about millet and sunflower plants, which were irrigated with low-mineralized drainage water 2 times a season as an additional water source. The plants were treated with Nanosilicon and AMINOSID Universal Si biopreparations. The fertilization procedure for millet was N-50, P-105, K-75 kg ha-1, while for sunflower, it was N-200, P-140, K-100 kg ha-1. The article also discusses changes in the volumetric mass of soil under conditions of water shortage in the experimental field.
