Classification of Grey-Cinnamon (Chestnut) Soils with Nutrient Source of the Shamkirchay Reservoir and Analysis of Morphogenetic Diagnostic Indices

Abstract

The mountain grey-cinnamon (chestnut) soils which are irrigated by the Shamkirchay water reservoir is formed mainly on the foothill, plain and partly on the mountainousborders and orographically on the northern east slope of the Little Caucasus are situated between 40039/ - 41000/ north latitude and 45050/ - 46020/ east longitude. The classification of mountain grey-cinnamon soils in the zone with 54263,74 ha on subtypes and analysis of the morphogenetic diagnostic indices has been given in the article. 7 subtypes of mountain grey-cinnamon soils are formed in the zone: separate morphological description of each subtype was analyzed in the article. At the same time, a modern state of the main physicochemical and fertility indices of the soils in the basin zone and information about the researches performed in the soils inside of the Shamkir, Goy-gol and Samukh borders have been presented. The diagnostic indices of the soil sections in the characteristic places, morphological description and agrochemical features of the soil profiles on subtypes and their analysis result were explanatory analyzed. Humus, total nitrogen, phosphorus and potassium, granulometric composition (sand, dust, silt and clay fractions) environment reaction of soil (pH) and calcareous (CaCO3) were fixed, statistically analyzed.
