Dr. Aid NPK 19 19 19 water soluble fertilizer for crops Product Name:Sulfur-Based Compound NPK Fertilizer Formula: N-P2O5-K2O Chloride: ＜3% Nitrogen: ＞15.5% Phosphorus Pentoxide: ＞15.5% Potassium oxide:＞15.5% Water insoluble :＜5% Melting point:80℃ State:Granular fertilizer Colour:white, red, yellow, OEM color Dr. Aid NPK water soluble fertilizers offer complete fertilization, to which trace elements are often added. The fertilization with an NPK water soluble fertilizer can be made in the B-barge. Each element of the fertilizer has its own effect: Nitrogen (N): mainly causes cell elongation in the growth phase of the plant.

Dr.Aid NPK fertilizers contain combinations of nitrogen, phosphorus, potassium and in most cases sulphur too – the most essential plant nutrients – designed to meet specific crop requirements to maximize crop yield and quality. When you apply nutrients using a true compound fertilizer you avoid the risk of segregation and uneven distribution that you get when using a blended fertilizer. You also get the reassurance of a sustainably manufactured and fully traceable fertilizer. NPK 12-12-36 Compound Fertilizer details: Formula: N-P2O5-K2O Chloride: ＜3% Nitrogen: ＞15.5%

The main production routes for compound NPKs are the nitro-phosphate process; chemical granulation (the process based on the neutralization of phosphoric acid and other acids that is followed by granulation); steam granulation (often called physical granulation); compaction; bulk blending. According to the law of fertilizer requirements for cash crops such as fruits and vegetables, scientific blending has the characteristics of stable and long fertilizer efficiency, easy absorption, and rich in crops.

Compound Fertilizer is the fertilizer which contains two or three nutrients of N, P, K. NPK fertilizers are three-component fertilizers providing nitrogen, phosphorus, and potassium. It is available in powder or granular form. Compound fertilizers show their nutrient content with three bold numbers on the package. Represented by three different major nutrient content: Nitrogen, Phosphorous, and Potash (Potassium), we can describe such content with the letters N-P-K. Nitrogen helps plant foliage to grow strong.

Sulfur (S) is an important nutrient often forgotten as a needed element in the soil’s mineral bank. Though it exists as elemental sulfur in some places on earth, sulfur is usually found as a natural compound, such as gypsum. Like nitrogen, it is also an important ingredient for the fabrication of proteins. A soil very high in sulfur can be acidic, but it takes an extremely high amount to cause damage to plants.
