There is a lot of land in my country that cannot be planted with crops, because the alkalization and salinization of these soils are serious, and crops cannot grow. Aluminum sulfate can be used to improve the salinization of the soil. The improvement effect of soda saline-alkali soil is very significant. The following Let's learn more about it.
In the case of adding an appropriate amount, the concentration of anions such as sulfate ions and chloride ions decreases significantly with the increase of the number of rinses. The concentrations of carbonate and bicarbonate also decreased significantly, but due to the influence of carbon dioxide in the air, the rate of decrease was not as fast as that of sulfate and chloride ions, but it also significantly improved the ionic results of the soil, making the soil more suitable for crop growth.
The chemical composition of the soil can also be significantly improved by leaching, but too many times of leaching will cause a large amount of added aluminum sulfate to flow away. Improvement of soil. Moreover, the rinsing and shaking process also destroyed the original aggregates and microaggregates in the soil, and repeated rinsing did not improve the physical properties of the soil, and even had a negative effect on the pH value of the soil solution.
When only adding aluminum sulfate without leaching the soil, the soil properties are significantly improved, especially for reducing soil alkalinity. The improvement effect of soil pH value, soil bulk density and soil particle size is very significant. Calcium and magnesium ions are also gradually released, which greatly reduces soil salinity. However, using soil modification alone cannot solve soil problems from the root cause. Because the soil still has a high salinity, the salinity problem of the soil cannot be improved, but the soil type is also converted from a soda type to a sulfuric acid type. Although it is not completely solved, it also alleviates the soil problem.
Combining the advantages and disadvantages of the two improvement methods, the combination of the two improvement methods can not only improve the soil alkalinity problem, but also improve the soil salinity problem, and better improve the soil environment. When the concentration of 0.8% was added, the soil was washed twice, and the improvement effect was better.
Through the above description, we have learned that aluminum sulfate combined with leaching can improve the salinization of the soil and make the soil more suitable for growth. The leaching alone cannot change the physical properties of the soil, and it is still necessary to cooperate with to use.
