AGROCHEMICAL PROPERTIES OF IRRIGATED MEADOW SAZ SOILS OF FURKAT AND BESHARIQ DISTRICT
Downloads
This article discusses the agrochemical properties of irrigated meadow saz soils distributed in the Furkat and Beshariq districts of Fergana region. The importance of humus, nitrogen, phosphorus and potassium elements in increasing the fertility of these soils is great. Humus is a complex structural substance in a changing state, constantly changing and renewing its composition. This change, first of all, concerns humic substances, carbohydrates, organic acids, alcohols, esters, aldehydes, nitrogenous substances, etc., as well as direct humic substances humic and ulmic acids, fulvic acids (crenic and apocrine), hematomelanic acid, humin and ulmin. As a result of the research, the total forms of these substances and the mobile forms of plant-necessary nutrient elements in the soil (mobile phosphorus, exchangeable potassium) and the amount of humus were determined.
