NPK compound fertilizer, the main nutrients vital to plants by weight are called macronutrients, including: nitrogen (N), phosphorus (P), and potassium (K) (i.e. N-P-K). Ammonia is main source of nitrogen. Urea is the main product for making nitrogen available to plant. Phosphorous is made available in form of super phosphate, Ammonium phosphate. Muriate of Potash (Potassium Chloride) is used for supply of Potassium. NPK fertilizers are soil amendments applied to promote plant growth, the main nutrients added in fertilizer are nitrogen, phosphorus, potassium, other nutrients are added in smaller amounts.



It is a quick acting manure in high concentration. It could meet the Nitrogen, Phosphorus and Potassium requirement of various crops and plants, using as base fertilizer, seed fertilizer and top application, especially in the drought, rainless area with deep placement. It could be widely used in vegetables, fruits, paddy rice and wheat, especially in deficient soil.



Flowers: Lilies, Carnations, Flower seedlings

Vegetables: Tomatoes, Peppers, Cucumbers, Lettuce, Cabbages, Eggplants, Cauliflowers, Potatoes, Vegetable seedlings

Fruit crops: Table grapes, Apples, Bananas, Watermelons, Muskmelons

NPK fertilizer is primarily composed of three main elements: Nitrogen (N), Phosphorus (P), and Potassium (K), each of these being essential in plant nutrition. Among other benefits, Nitrogen helps plants grow quickly, while also increasing the production of seed and fruit, and bettering the quality of leaf and forage crops. Nitrogen is also a component of chlorophyll, the substance that gives plants their green color, and also aids in photosynthesis.


Phosphorus, also a key player in the photosynthesis process, plays a vital role in a variety of the things needed by plants. Phosphorus supports the formation of oils, sugars, and starches. The transformation of solar energy into chemical energy is also aided by phosphorus, as well as is development of the plant, and the ability to withstand stress. Additionally, phosphorus encourages the growth of roots, and promotes blooming.


Potassium, the third essential nutrient plants demand, assists in photosynthesis, fruit quality, the building of protein, and the reduction of disease.

potassium nitrate


Nitrogen (N) – nitrogen is largely responsible for the growth of leaves on the plant.

Phosphorus (P) – Phosphorus is largely responsible for root growth and flower and fruit development.

Potassium (K) – Potassium is a nutrient that helps the overall functions of the plant perform correctly.
