Аннотация
Представлены данные по содержанию и запасам гумуса, валовых и подвижных форм азота, фосфора и калия в староорошаемых луговых аллювиальных почвах шести районов Бухарской области Республики Узбекистан; дана оценка их современного состояния по обеспеченности элементами минерального питания. Содержание гумуса в пахотном слое во всех районах составляет 0,62–0,97 % и уменьшается по почвенному профилю до 0,20–0,53 % на глубине больше 1,5 м. Валовое количество азота в пахотном слое 0,049–0,088 %; фосфора 0,21–0,35, калия 0,82–2,80 %. По содержанию нитратного азота в пахотном слое отмечаются значительные различия между районами области: в северных 1,7–5,5 мг/кг. почвы, в южных 46,8–57,7 мг/кг. Содержание подвижных форм фосфора в пахотном слое всех почв составляет 10,8–23,5 мг/кг. почвы, калия 108–150 мг/кг.
