Functions
1) Enrich soil: accelerate the structure forming of soil particulars, reduce salt content, breakthrough mineralized layer, and
effectively solve the soil salinization caused by over fertilization.
2) Balance nutrition: it contains Nitrogen, Potassium, Phosphorus that required by plant growth.
3) Root promoter and protector: the natural root growth factors, e.g. amino acid and fulvic acid, and their Useful metabolites
are promoting root growth even in low temperature and less sunshine to enhance the root absorption ability.
4) Relieve pesticide harzards: the plants internal regulator and useful metabolites are both able to enrich and activate organic
cells, relieve pesticides and fertilizers hazards and restore the physiological function of crops.
5) Disease resistance and output increasing: the added beneficial bacterium is albe to solve root disease and increase output.
APPLICATION:
1. Potassium Sulphate can be used as the raw material to produce multiple-element compound fertilizer, or as potassium fertilizer to fertilize field, especially applicable to chloride-resistant industrial crops such as tobacco, grape, cotton, beet.
2. It is mainly used for fruit and vegetables (tomato, potato) and crops (corn), the main function is to improve the oil content of oil-bearing crops,it can accelerate the mature process of fruits and vegetables, increase crops' fiber length, strength, for example, cotton. It can also improve the soil ingredient, enhance the production capacity, fertilizer can be berry in the soil, can be directly sprayed on the plant body.
