ABŞERON RAYONU ZEYTUNALTI SUVARILAN BOZ-QONUR TORPAQLARIN MÜNBİTLİK MODELİ. (Azerbaijani)

Fertility model of under olive irrigated grey-brown soils of Absheron region. (English)

Information about the geographical position, relief, climate, hydrography, vegetation of Absheron region is provided. 3 soil pieces were taken from under olive lands in Zigh settlement. These soil samples were analyzed at the Institute of Soil Science and Agrochemistry. The main indicators of fertility in these soils - humus, total nitrogen, active phosphorus, exchangeable potassium, granulometric content, pH and amount of absorbed bases were determined. Then, data on the physical, physico-chemical and chemical properties of the soil were collected, and fertility models of under olive soils were compiled based on them. The results of these analyzes are reflected in the blocks of the fertility model. It was determined that as a result of monitoring, during the years 1994-2022, humus in these soils was 0.1%, humus reserve was 0.1 t/hectare, total phosphorus was 0.01%, total potassium was 0.21%, total absorbed bases were 0.2 mg/eq, porosity 2 %, N/NH4 0.3 mg/kg, <0.01 mm 1.2 %, >0.25 mm 1%, CO2 0.03 % reduced, total nitrogen 0.01 %, pH 0.1; hygroscopic moisture increased by 0.02%, density by 0.03 g/cm³, N/NO3 by 0.2 mg/kg. A system of measures has been developed for the management of these lands. [ABSTRACT FROM AUTHOR]
