Abstract

The baseline agrochemical condition Of irrigated meadow soils was analyzed, focusing on the patterns of vertical distribution of humus, as well as total and available nutrients (nitrogen, phosphorus, potassium) along the 0–100 cm profile. The results show that in the upper arable layer (0–30 cm), the content of humus is 1.965%, total nitrogen is 0.097%, phosphorus is 0.165%, and potassium is 1.65%. A regular decrease in humus and nutrient concentrations was observed moving down into the lower soil layers (30–100 cm). Based on the agrochemical assessment of the soil regarding the availability status of mobile nutrients, recommendations were provided to optimize the fertilization system.
