Nitrogen-sulfur-based compound fertilizer is a new type of environmentally friendly compound fertilizer made primarily from nitrate phosphate fertilizer and potassium sulfate. Its nitrogen element exists in the form of nitrate nitrogen, which can be directly absorbed by crops, featuring rapid fertilization and high utilization rate. This fertilizer is suitable for cash crops such as fruits and vegetables, as well as chlorine-sensitive crops such as tobacco. It can effectively improve fruit quality and crop resistance, and exhibits better adaptability in saline-alkali and sulfur-deficient soils. Produced using advanced processes such as high-tower melt granulation, nitrate-sulfur-based compound fertilizer can achieve a high concentration ratio of ≥48% total nutrients, and can be used as both base fertilizer and top dressing in agricultural production.

FUNCTIONAL CHARACTERISTICS

Fast-acting Nutrients: Nitrate nitrogen can be absorbed by roots without conversion; fertilizer effect is visible 3-7 days after application.

Quality Enhancement: Increases vitamin C content in fruits and vegetables by 15%-30% and protein content in grain crops.

Soil Improvement: Sulfur replenishment improves sulfur-deficient soils; nitrate ions alleviate soil compaction in saline-alkali areas.

Environmentally Friendly: Avoids soil acidification caused by chloride residues and reduces the risk of nitrite accumulation.

APPLICATION GUIDELINES

Dryland Application: 30-40 kg per acre as base fertilizer; topdressing interval 15 days. 20-Day Application Limitations for Paddy Fields: In rainy areas, deep application and covering with soil are necessary to prevent nitrate leaching.

Compatibility Contraindications: Do not mix with uncomposted organic fertilizer. Maintain a 10cm distance from seeds to prevent seedling burn.

Safety Interval: Stop application 20 days before harvest to ensure agricultural product safety.

CROP COMPATIBILITY

Cash Crops: Suitable for high-value crops such as fruits and vegetables, as well as sulfur-loving crops such as legumes, onions, garlic, and grapes. Significantly increases protein and vitamin C content and improves agricultural product quality.

Fruit Trees: Applying during the grape ripening period increases soluble solids content by 2-3 degrees.

Leafy Vegetables: Suitable for high-value crops such as fruits and vegetables, as well as sulfur-loving crops such as legumes, onions, garlic, and grapes. Significantly increases protein and vitamin C content and improves agricultural product quality.

Tuber Crops: Nitrogen-sulfur-based compound fertilizer is suitable for cash crops such as fruits and vegetables that require high fertilizer amounts and frequent topdressing. It promotes root development and fruit enlargement, improving agricultural product quality.
