                Product features:

                1. Good activity and high fertilizer efficiency: polymerized phosphorus can chelate medium and trace elements, improve nutrient forms, improve the availability of phosphorus and medium and trace elements, and promote dissolution and absorption. Compared with orthophosphate, polymeric phosphorus has a longer moving distance, which can move to the deep soil, nourish the deep roots of plants, and has higher fertilizer efficiency.

                2. High chelation and long fertilizer efficiency: polymerized phosphorus chelates metal ions, so it is not easy to be fixed; Plants can not directly absorb synergistic (granular) polymerized phosphorus, which needs to be degraded to orthophosphate before it can be absorbed by roots. All products containing polymerized phosphorus have high utilization rate and long fertilizer efficiency period, which can meet the phosphorus demand of crops in the middle and later stage.

                3. Polyphosphate can keep water: adding polyphosphate to food can improve the water retention of food, and adding polyphosphate to fertilizer can improve the drought resistance of crops.

                4. Improve the soil, raise roots and resist continuous cropping: the movement ability of polymerized phosphorus is strong, especially in alkaline soil, which has a greater movement distance. Through chelating metal ions and phosphorus and nitrogen fixed by the soil, it can activate and harden the soil, and correct various malnutrition diseases caused by plant nutrient deficiency.

                usage method

                1. Applicable crops: all kinds of fields and cash crops

                2. Fertilization period: base fertilizer or seed fertilizer before vegetable planting, after fruit harvest and before field crop sowing.

                3. Fertilization method: close planting crops such as wheat, millet, spinach, etc. can be spread and then ploughed or furrowed; Wide row crops such as corn, potato, peanut, cotton, fruits and vegetables can be applied in furrow to ensure higher fertilizer efficiency.

                4. Fertilizer dosage: base fertilizer dosage 15-50 kg / mu, seed fertilizer dosage 4-5 kg / mu.

                5. It should be used with other fertilizers.

                matters needing attention

                1. When the amount of concentrated fertilization is more than 5 kg, attention should be paid to the isolation of seed and fertilizer.

                2. The specific amount of fertilizer can be determined according to the characteristics of crop fertilizer demand, soil fertility, fertilization method and the amount of other compound fertilizers.

                3. This product contains biuret, improper use will cause damage to crops.
