ДИНАМИКА АГРОЭКОЛОГИЧЕСКОГО СОСТОЯНИЯ ЧЕРНОЗЕМА ТИПИЧНОГО ПОД ЗАЛЕЖЬЮ

DYNAMICS OF AGRO-ECOLOGICAL STATE OF TYPICAL CHERNOZEM UNDER FALLOW LANDS

ДИНАМИКА АГРОЭКОЛОГИЧЕСКОГО СОСТОЯНИЯ ЧЕРНОЗЕМА ТИПИЧНОГО ПОД ЗАЛЕЖЬЮ

Abstract

На разновозрастной залежи, расположенной на территории опытного поля ВНИИ земледелия и защиты почв от эрозии (Курская область, Медвенский район), в течение 16 лет изучали особенности динамики показателей агроэкологического состояния чернозема типичного залежной экосистемы возрастом 17, 25 и 33 года. Установлено, что многолетнее консервирование (перевод пашни в залежь) чернозема типичного приводит к повышению уровня его плодородия. При самовосстановлении залежных почв отмечено возрастание содержания органического вещества (органического углерода почвы, негумифицированного органического вещества, подвижных гумусовых веществ, подвижных гуминовых кислот, подвижных фульвокислот), улучшение агрофизических свойств, а также положительная тенденция увеличения других агрохимических показателей, значительное возрастание водоустойчивости почвы. С повышением возраста залежи надземная фитомасса увеличивается, а масса войлока уменьшается. Отсутствие длительной антропогенной нагрузки на почвы приводит к улучшению ее агроэкологического состояния, что, несомненно, отразится на увеличении экологической емкости агроландшафта. The dynamics of indicators of agroecological state of Chernozem typical of a fallow ecosystem aged 17, 25 and 33 years were studied for 16 years on a multi-age Deposit located on the territory of the experimental field of the Institute of agriculture and soil protection from erosion (Kursk region, Medvensky district). It is established that long-term conservation (transfer of arable land to a deposit) of typical Chernozem lead to an increase in its fertility. During self- regenerating of fallow soils, there was an increase in the content of organic matter (organic carbon of the soil, inhumified organic matter, mobile humus substances, mobile humic acids, mobile fulvic acids), improvement of agrophysical properties, as well as a positive trend of increasing other agrochemical indicators, a significant increase in soil water resistance. With increasing fallow age, the aboveground phytomass increased, and the weight of felt decreases. The absence of a long-term anthropogenic load on the soil lead to the improvement in its agroecological state, which will undoubtedly affect the increase in the ecological capacity of the agrolandscape.
