В статье приведены основные агрохимические показатели светло-каштановой почвы опытного поля Гобустанской областной опытной станции, расположенной на территории кадастрового района Горно-Ширван, юго-восточного склона Большого Кавказского хребта в Азербайджане. Одним из лимитирующих факторов в условиях богары являются осадки Определена продолжительность вегетационного периода образцов и качество ячменя в зависимости от температурных факторов проведенных в 2016-2019 гг, установлены оптимальные дозы внесения удобрений. Значения pH в пахотном слое (0-25 см) находились в пределе от 8,1-8,4 (25-50 см) до 8,7-8,8 (50-70 см). Реакция среды почвы варьирует от слабощелочной до сильнощелочной. Почва карбонатная. Почвы исследуемого поля (Гобустанский РЭС (район Мараза)) слабо- и средне обеспечены подвижным фосфором. Общее содержание гумуса в пахотном слое колеблется от 2,23 % до 2,29 %, снижаясь с глубиной. Общий азот на глубине 0-25 см составил 0,165 % - 0,179 %, а с глубиной уменьшился более чем в два раза. Содержание легкогидролизуемого азота находилось в пределах 13-74 мг/кг почвы. Общее содержание фосфора на глубине 0–25 см составило от 0,18 % до 0,12–5 % в зависимости от года исследования и постепенно снижалось в нижних слоях почвы. Количество активного фосфора находилось в пределах от 30,4-33 мг/кг почвы. Количество обменного калия составило от 269-292 мг/кг почвы, которое постепенно снижалось с глубиной. Определена динамика содержания фосфора и калия в почве на полях с сортом ячмень «Джалилабад 19», в зависимости от роста посева и норм удобрений.

The article summarizes the main agrochemical parameters in the light-chestnut soil of experimental field of Gobustan Regional Experimental Station situated in the territory of the cadastral district of Mountainous-Shirvan, on the southeast slope of the Greater Caucasus Mountains Range in Azerbaijan have been determined. The precipitation, which is the main limiting factor in rainfed regions,was quantified for the 2016-2019 vegetation years. The values of pH in the plowing layer (0-25 sm) was found to range between 8.1-8.4 (25-50 cm), and 8.7-8.8 (50-70 cm). So the plowing layer had weak and lower layers had strong alkaline properties. The soil contains carbonates. The fields of Gobustan RES (Maraza area) are of medium quality soils. Total humus ranged from 2.23 % to 2.29 % in the plowing layer and decreased in the lower layers. Total nitrogen at the depth of 0-25 cm was 0.165 %-0.179 %, which decreased in the lower layers. The analysis shows that the average amount (in 4 years) of easily hydrolyzed nitrogen at a depth of 0-25 cm varied between 45-74 mg per 1 kg soil, 25-31 mg at a depth of 25-50 cm and 13-17 mg at a depth of 50-70 cm. The total phosphorus content at 0–25 cm depth ranged from 0.18 % to 0.12 5 %, depending on the years of the study, and gradually decreased in the lower layers.The amount of active phosphorus was 30.4-33 mg/kg at a depth of 0-25 cm during 4 years, and amount of variable potassium was 269-292 mg/kg, which gradually decreased in the lower layers. Dynamics of phosphorus and potassium in soil was determined in relation to the growth stages, sowing and fertilizer rates of the “Jalilabad 19”barley variety.
