Advantages of 19-31-4 Blended Fertilizer (Potassium-containing diammonium type)

1. Ultra-high phosphorus formula, powerfully promotes root and seedling growth

31% Ultra-high phosphorus content: With diammonium phosphate as the core phosphorus source, this is a typical high-phosphorus root-promoting formula that powerfully promotes root development, tillering, and flower bud differentiation, especially suitable for use during the seedling, transplanting, and flower bud differentiation stages.

19% Nitrogen guarantee: Meets the needs of seedling stem and leaf growth, avoiding yellowing and weak seedlings caused by nitrogen deficiency, achieving a synergistic effect of "nitrogen promoting growth and phosphorus promoting root development."

4% Basic potassium supplementation: Provides basic potassium nutrition, enhances crop resistance, and stores energy for later growth and fruiting.

2. Pure potassium sulfate type, safe and suitable for chlorine-sensitive crops

Chlorine-free and safe: Using pure potassium sulfate technology, it is completely free of chloride ions, making it highly safe for chlorine-sensitive crops such as tobacco, grapes, potatoes, and watermelons, avoiding salt damage and quality decline. Salt and Alkali Resistance + Anti-Compacting: The formula inherently possesses salt and alkali resistance and anti-compacting functions, activating the soil, improving soil aggregate structure, and enhancing soil water and fertilizer retention capacity, making it particularly suitable for saline-alkali land and continuously cropped fields.

3. Scientific Processing, High-Efficiency Utilization

Balanced and Comprehensive Nutrients: Scientifically formulated with nitrogen, phosphorus, and potassium to activate residual nutrients in the soil and improve fertilizer utilization. Flexible Application: Can be used as base fertilizer or top dressing, employing various methods such as broadcasting, strip application, and hole application, making operation convenient. Clear Safety Precautions: Contains biuret; avoid direct contact with seeds, stems, and leaves. Cover with soil after fertilization to prevent burning seeds and seedlings.

19-31-4 Applicable Scenarios for Blended Fertilizer (Potassium-containing diammonium type): Base fertilizer/seedling root-promoting fertilizer for chlorine-sensitive crops such as tobacco, grapes, potatoes, and watermelons; Post-planting fertilizer for fruit trees and vegetables to help seedlings recover and fertilizer to protect flowers during flower bud differentiation; Soil improvement projects for saline-alkali land and compacted soils; Topdressing for seedling root promotion in field crops (wheat, corn, rice).
