18-25-5 Blended fertilizer（Potassium-containing diammonium type）

To help farmers use fertilizers scientifically, Rongda Fertilizer provides a full range of services from pre-sales to after-sales. In the pre-sales stage, technicians collect soil samples for testing and develop personalized fertilization plans based on the results. During fertilization, agricultural consultants regularly visit the fields to guide farmers in adjusting the amount and frequency of fertilizer application. After harvest, the company assists farmers in yield measurement and connects them with grain traders, resolving any concerns about post-harvest sales. Currently, this fertilizer has passed national import and export inspection and quarantine certification and, in addition to the domestic market, is exported to Southeast Asia, serving the cultivation of crops such as rice and rubber there.

Advantages of 18-25-5 Blended fertilizer（Potassium-containing diammonium type）

1. High-phosphorus root-promoting formula, laying the foundation for high yield

25% High Phosphorus Content: With diammonium phosphate as the core phosphorus source, it strongly promotes root development, tillering, and flower bud differentiation in crops. It is especially suitable for use during the seedling, transplanting, and flower bud differentiation stages, serving as the core formula for "promoting strong roots and seedlings, and protecting flowers and fruits."18% Nitrogen Guarantee: Meets the needs of crop stem and leaf growth during the seedling stage, avoiding yellowing and weak seedlings caused by nitrogen deficiency, achieving a synergistic effect of "nitrogen promoting growth and phosphorus promoting root development."5% Basic Potassium Supplement: Provides basic potassium nutrition, enhances crop resistance, and stores energy for later growth and fruit setting.

2. Pure Potassium Sulfate Type, Safe and Suitable for Chlorine-Sensitive Crops

Chlorine-Free and Safe: Utilizes pure potassium sulfate technology, 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 resistant + anti-caking: The formula has built-in salt and alkali resistant and anti-caking functions, which can activate the soil, improve the aggregate structure, and enhance the soil's water and fertilizer retention capacity, making it especially suitable for saline-alkali land and continuously cropped land.

3. Scientific Process, 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, and can be applied in various ways such as broadcasting, strip application, and hole application, making it easy to operate.Clear Safety Warnings: Contains biuret; avoid direct contact with seeds, stems, and leaves. Cover with soil after application to prevent burning seeds and seedlings.

18-25-5 Blended fertilizer (Potassium-containing diammonium type) is suitable for: 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; Saline-alkali soil and compacted soil improvement projects; Topdressing for seedling root promotion in field crops (wheat, corn, rice).
