The research was conducted on meadow crusty multi-sodium salt flats sulfate-soda salting. The subject of the study was the long-term aftereffect of the half(21 t/ha) and a full dose (43 t/ha) of phosphogypsum for a layer of 0–30 cm. Research has shown, what is the 53-year period of action the half-dose effect was extremely weak. Model experiments using tubes have shown, that filtration capacity is under control (virgin soil) 83% due to the introduction of meliorant on the background. The half-dose determination coefficient was 67%. The coefficient of determination was 66 on the reclaimed salt shaker with a full dose%, at the same time, it took 3–4 times less to attach phosphogypsum, for maximum filtration capacity, at more than half the dose during model experiments.

摘要

The research was conducted on meadow crusty multi-sodium salt flats sulfate-soda salting. The subject of the study was the long-term aftereffect of the half(21 t/ha) and a full dose (43 t/ha) of phosphogypsum for a layer of 0–30 cm. Research has shown, what is the 53-year period of action the half-dose effect was extremely weak. Model experiments using tubes have shown, that filtration capacity is under control (virgin soil) 83% due to the introduction of meliorant on the background. The half-dose determination coefficient was 67%. The coefficient of determination was 66 on the reclaimed salt shaker with a full dose%, at the same time, it took 3–4 times less to attach phosphogypsum, for maximum filtration capacity, at more than half the dose during model experiments.
