The present study aims to describes physicochemical properties of the slope mountain brown soils under perennial plantings technology in order to increase the productivity of soils and, in particular, saving water resources by using modern drip irrigation. For this purpose, watering of orchards located on the slope mountain brown soils of the southeastern of the Greater Caucasus were investigated. Chemical characteristics of the soil sampled from the studied area, in upper layer vary among gyroscopic humidity 6,18-6,23%, humus 4,03-4,30%, total nitrogen 0,252- 0,238%, total phosphorus 12,22-13,33 mg/kg; CO2 5,58%; CaCO3 in relation to CO2 - 12,70%; Ca in 100gr soil – 30,5 mg/ kg; Ca-84,72-87,14%; Mg-12,86-15,28%. Moreover, according to morphological characteristics of selected samples collected the studied region, mechanical texture of this soil is heavy clay. Amount of physical clay in the upper layers of this soil vary between 67,20-69,20%, and amount of clay vary between 34,40-39-20%; whereas in the lower layer, this amount vary between 65,20-77,20%; 29,60-32,80%, respectively. Structural texture of this soil and amount of structural parts higher than 1mm in the upper layer of the soil also varies between 61,72-62,33% and 68,05- 68,80%, between the upper and lower layers, respectively. Overally, results show that soil cover and climatic conditions of the studied area emphasize on a modern irrigation method with less need to freshwater.
