Leveraging its advantages of "high purity and low impurities", caprolactam-grade ammonium sulfate crystals are particularly suitable for cultivation scenarios with high requirements for fertilizer safety and quality. The specific applications are as follows:
It is applicable to organic vegetables (e.g., lettuce, tomatoes), green fruits (e.g., strawberries, blueberries), and Chinese medicinal materials (e.g., ginseng, wolfberries). Due to its extremely low content of heavy metals and chloride ions, it can prevent the accumulation of pollutants in crops, meeting the standards for organic certification or green food.
For chlorine-sensitive crops (e.g., tobacco, potatoes, grapes), it not only safely supplements nitrogen but also improves crop quality through sulfate ions:
- After application on tobacco, the combustibility of tobacco leaves is better, and the nicotine content is more stable;
- After application on potatoes, the starch content increases by 3%-5%, and the taste is improved.
When cultivating in soils with mild heavy metal pollution (e.g., plots with excessive lead or cadmium), its low-impurity characteristic can avoid worsening soil pollution. At the same time, sulfate ions can combine with free heavy metal ions in the soil to form stable sulfate precipitates (e.g., lead sulfate, cadmium sulfate), reducing the bioavailability of heavy metals.
When improving alkaline soils (pH > 7.5), its high purity ensures no additional impurities (such as phenols in coking-grade ammonium sulfate) are introduced. It can safely adjust the soil pH value and improve the availability of medium and trace elements such as calcium and magnesium.
