Bulk Blending Fertilizer 19-19-19 (Chloride Based)

• Product Overview

• NPK 19-19-19: This indicates that the total nutrient content in the fertilizer is ≥57%

·N (nitrogen) content of 19% : Promotes the growth of crop stems and leaves, increases chlorophyll content, and enhances photosynthesis. 

·P₂O₅ (phosphorus) content of 19% : Promotes root development, flower bud differentiation, fruit ripening, and enhances stress resistance. 

·K₂O (potassium) content of 19% : Enhances the crop's resistance to lodging, diseases and pests, and improves quality and yield.

• "Blended fertilizer" : Also known as BB fertilizer, it is made by blending single or compound fertilizer particles with similar particle sizes in proportion through physical methods. Its characteristics are:

· Flexible formula: It can be adjusted according to soil and crop requirements. 

· Uniform nutrients: The particles are uniform, and each particle contains nutrients. 

·The production cost is relatively low.

• Main raw materials and processes

· Nitrogen source: Large granular urea (containing 46% N). 

· Phosphorus source: monoammonium phosphate (e.g. 11-52-0) or diammonium phosphate (18-46-0). 

· Potassium source: Potassium chloride (containing 60% K₂O) or potassium sulfate (containing 50% K₂O).

• Outstanding features

· Balanced nutrition: The ratio of the three elements is 1:1:1, which is suitable for most growth stages of crops and is especially conducive to balanced nutrient absorption. 

· High concentration and high efficiency: It has a high total nutrient content, requires a relatively small dosage, and has low transportation and application costs. 

· Strong versatility: It has relatively low selectivity for soil and crops, and is especially suitable for situations where the soil testing formula is unclear or where balanced nutrition needs to be replenished quickly. 

· Good water solubility: High-quality products have high water solubility and can be used in integrated water and fertilizer systems such as drip irrigation and sprinkler irrigation.

• Applicable crops and periods
  

· Field crops: corn, wheat, rice (to be adjusted in the middle and later stages). 

· Cash crops: cotton, rapeseed, peanuts, soybeans. 

· Fruit trees: apples, citrus fruits, grapes, peaches, etc. (young fruit stage and fruit expansion stage). 

· Vegetables: tomatoes, cucumbers, peppers, leafy vegetables, etc.

• Optimal application period

• Important notes

· Avoid blind application: Long-term use may lead to the accumulation of phosphorus and potassium in the soil. Regular soil testing and formula adjustment should be carried out. 

· Use with caution on chlorine-sensitive crops: If the raw material is potassium chloride, for chlorine-sensitive crops such as tobacco, potatoes, and some fruit trees, potassium sulfate type should be selected. 

· Seed and root system safety: When used as seed fertilizer, avoid direct contact with seeds to prevent seedling burning. 

· Combined application: It is recommended to use it in combination with organic fertilizers to improve soil structure and enhance fertilizer efficiency. 

· Weather and soil: Avoid application on rainy days. For sandy soil, apply in small amounts frequently.

• Summary

· Comprehensive and balanced nutrients, convenient to apply. Address the balanced demand of crops for the three major elements in the short term. The production process is simple and the price is usually more advantageous than that of compound fertilizers with the same content.
