UREA

Urea, also known as carbamide, is an organic compound with the chemical formula CO(NH2)2. This amide has two –NH2 groups joined by a carbonyl (C=O) functional group.

DAP

Di-Ammonium Phosphate (DAP) is the world’s most widely used Phosphorus fertilizer. It is made from two common constituents in the fertilizer industry – Nitrogen (N) and Phosphorus (P). It is relatively high in nutrient content and its excellent physical properties make it a popular choice in farming and other industries.

TSP

The concept of TSP production is relativelysimple. Non-granular TSP is commonly producedby reacting finely ground phosphate rock with liquid phosphoric acid in a cone-typemixer. Granular TSP is made similarly, but the resulting slurry is sprayed as a coatingonto small particles to build granules of the desired size.

NPK

The three numbers on fertilizer represents the value of the three macro-nutrients used by plants. These macro-nutrients are nitrogen (N), phosphorus (P) and potassium (K) or NPK for short. The higher the number, the more concentrated the nutrient is in the fertilizer. For example, numbers on fertilizer listed as 20-5-5 has four times more nitrogen in it than phosphorus and potassium. A 20-20-20 fertilizer has twice as much concentration of all three nutrients than 10-10-10.
