Природные запасы магния в почвах Ставропольской возвышенности при разном уровне агрогенного воздействия в агроландшафте

Природные запасы магния в почвах Ставропольской возвышенности при разном уровне агрогенного воздействия в агроландшафте

Abstract

Проведена дифференцированная оценка природных запасов магния на основе анализа его содержания в гранулометрических фракциях разной размерности агрочерноземов байрачных лесостепей Ставропольской возвышенности на примере полигона «Агроландшафт». Изучено влияние систематического применения различных доз полного минерального удобрения на изменения резервов МдО в почвах разной ландшафтной принадлежности. Почвы полигона характеризуются довольно высокими, типичными для черноземов природными запасами общего магния (1615.3475 мг/100 г). Наиболее гумусированные и тяжелые почвы нижней части склона существенно отличаются от почв окраины плакора и верхней части склона, как по содержанию валового магния, так и по его распределению по категориям резервов. От применения минеральных удобрений значительных изменений в поведении различных категорий резервов магния в почвах всех ландшафтных таксонов за семилетний период не произошло. Однако существует опасность дальнейшего усиления начавшихся процессов разрушения минералов вследствие подкисления почв от повышенных доз минеральных удобрений, что может способствовать истощению естественных запасов элементов питания в почвах.

Held differentiated assessment of the natural resources of magnesium on the basis of the analysis of its contents in size fractions of different sizes agrochernozemov bayrachnye steppe Stavropol Upland an example polygon «agrarian landscapes.» The effect of the systematic application of different doses of complete fertilizer on MgO in reserves in soils of different landscape supplies. Soils are characterized by a high polygon, typical chernozems natural resources of the total magnesium 1615-3475 mg/100g most severe soil humus and bottom of the slope differ significantly from the edge of watershed soil and the top of the slope on both the content of the gross magnesium and its distribution by category of reserves. From the use of mineral fertilizers of significant changes in the behavior of the various categories of reserves of magnesium in soil taxa for all landscape of seven years did not happen. However, there is a danger of further strengthening begin the process of destruction of minerals due to soil acidification by high doses of fertilizers, which may contribute to the depletion of natural stocks of batteries in soils.
