Evaluation of water-stability indicators of light gray brown (chestnut) soils in the condition of Mountain Shirvan

In article, the influence of tillage methods (conventional, minimal, zero), predecessor (wheat, barley, fallow) and mineral fertilizer on the water-stability indicators of the soil of rain-fed condition Mountain Shirvan is explained. In 2014-2017 years, the results of the research conducted in the agrocenosis of cereal crops in light gray brown (chestnut) soils show that the water-stability indicators of the soil exhibit intra-vegetation dynamics depending on factors such as the predecessor, tillage methods, growth stages of cereal. Furthermore, these indicators vary in the plow and sub-plough layers. According to the research results, the water-stability of light mountain gray brown soils in the conditions of Mountain Shirvan can be evaluated as ‘weak’ and ‘moderate’ based on the values of >0.25 mm water-stable aggregates and as ‘very weak’ and ‘weak’ based on the values of the mean weight diameter of water-stable aggregates, using the provided classifications.
