WSF fertilizers can increase yields of a healthy crop beyond the capabilities of conventional, soil applied fertilizers. Used correctly water soluble fertilizers can provide an attractive economic return on investment over and above that obtained from soil applied fertilizers. WSF fertilizers are designed to meet a need for a properly balanced, highly concentrated product that can be applied by aircraft or ground rigs, as well as used in dilute or concentrated sprinkler or injector systems. 
 
 
Produce Benefits:
100% soluble nutritional foliage spraying that can be applied to fruit and offer crops nearing maturity. There are very little or no visible residues at harvest. Safes and availabilities for many different species and sizes of plants grow together in green houses and nurseries. Contain elements which provide the entire spectrum of nutrients needed for a wide variety of plants.
Providing immediately available nutrients for plants, and particularly they are suitable for fast growing field, such as vegetables and nursery crops.
100% soluble and does not need to be agitated in the tank.
Formulas could be compatible with most common pesticides and fungicides - especially suited for aircraft applications.
Uniform in analysis every drop container the same analysis.
Contain chelating and sequestering agents to assure availability without precipitation of the major and micronutrients.
 
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 PotassiumNPK 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.
 
Applications
 
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.
  
Usages
 
Foliar application: Dilute 800-1200 times, with 7 to 10 day intervals
 
Fertigation: 45-75kg/ha, with 7 to 10 day intervals
  
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.
