Description
Description:
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
Applications:
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.
