Chemical fertilizer is a type of fertilizer in the form of dry solid pellets that provide essential nutrients to plants and improve soil properties. It releases nutrients over weeks to months, feeding plants gradually.

Like liquid fertilizers, it contains 3 essential nutrients namely nitrogen (N), phosphorus (P), and potassium (K). The lack of any element will affect the normal growth and development of crops.

NPK elements Effects Element deficiency Nitrogen Promote cell division and growth The plants are short and thin with yellowish-green leaves Phosphorus Promote sugar movement and strengthen roots and blooms The plants are small, low in sugar, and the seed wilt. Potassium Promote photosynthesis and improve the plants cold, disease, and lodging resistance The plants are withered, soft tissue, and easy to lodge

Therefore, agriculture cannot be developed without fertilizers. Granular fertilizers are essential for increasing crop yields. This blog is a step-by-step guide to Granular Fertilizers Production Process.

Step 1 Mixing of the fertilizer ingredients

Based on the soil analysis, you can identify the specific nutrients required to supplement the soil and determine the nutrient ratios. Once the raw materials are acquired, it is time to create the granular fertilizer blend.

Use a mixer to obtain a homogeneous mixture. The uniform mixing of fertilizers not only refers to the individual mixing of new substances like nitrogen, phosphorus, and potassium, but also includes the mixing of new substances and returned substances.

The granulated fertilizers can be divided into two types according to their composition.

1. Nitrogen fertilizer, phosphorus fertilizer, potash fertilizer, and compound fertilizer (NPK fertilizer)

Common ingredients in this type of granular fertilizer include urea (nitrogen), phosphate rock (phosphorus), potassium chloride (potassium), and various sources of micronutrients like iron, zinc, and manganese.

Raw materials such as urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, coarse whiting, single superphosphate), potassium chloride (potassium sulfate), etc. shall be provided at a certain ratio (according to market demand and soil test results in various regions).
