AMUDARYO QADIMGI DELTASI SUG‘ORILADIGAN TUPROQLARINING FERMENTATIV FAOLLIGI VA MAVSUMIY DINAMIKASI

Abstract

This study is aimed at assessing the enzymatic activity of irrigated barrenmeadow, meadow-alluvial, and meadow-desert soils in the ancient delta of the Amu Darya. The dynamics of catalase, peroxidase, polyphenol oxidase, and urease enzymes were investigated in the 0–30 cm and 30–60 cm soil layers during spring, summer, and autumn seasons. The results showed that soil texture, moisture regime, and organic matter content are the main regulators of enzymatic processes. The highest enzymatic activity was recorded in medium loamy irrigated barren-meadow soils.
