Compound fertilizer national standards stipulate that compound fertilizers containing chlorine must be marked with chloride ion content, such as low chloride (containing chloride ion 3-15%), medium chloride (containing chloride ion 15-30%), high chloride (containing chloride ion 30% or more).
Appropriate application of wheat, corn, asparagus and other field crops is not only harmless, but also beneficial to improve yields.
In general, the application of chlorine-based compound fertilizer, tobacco, potatoes, sweet potatoes, watermelon, grapes, sugar beets, cabbage, peppers, eggplant, soybeans, lettuce and other crops resistant to chlorine have adverse effects on yield and quality, seriously reducing the economic benefits of such cash crops. At the same time, chlorine-based compound fertilizer in the soil to form a large number of chlorine ion residues, easy to cause soil consolidation, salinization, alkalinization and other undesirable phenomena, thus deteriorating the soil environment, so that the crop nutrient absorption capacity is reduced.
