Characteristic
100% fast water soluble, clear and transparent solution, suitable for various irrigation and fertilization systems: green and safe, no chloride, sodium, heavy metals ions, no pollutant residues; Nutrients are fast-acting, containing ureic nitrogen and phosphate phosphorus, which are easily absorbed by crops; Nitrogen and phosphorus synergy can reduce urea volatilization loss and improve nitrogen nutrient utilization efficiency;Strong acidic fertilizer, pH 1.8 -2.2, has excellent activation effect on other macroelements and medium and trace elements in the soil, so as to facilitate the full absorption and utilization of crops.
————————————————————————————————————————
Function
1. It is usually mixed with other water-soluble nitrogen fertilizers (urea, ammonium nitrate) and potassium fertilizers (potassium nitrate) to form as NPK fertilizers to provide balanced nutrition for crops;
2. The PH value is very low, especially suitable for irrigation and fertilization systems in alkaline soil or areas with hard water quality, which can effectively reduce insoluble precipitation and make the irrigation system clean and smooth;
3. The product has an acidifying effect on the soil, which can increase the availability of nutrients in the soil, thereby improving the absorption and utilization rate of nutrients by crops.
————————————————————————————————————————
Application
It is suitable for all kinds of crops and soils, suitable for foliar spraying, drip irrigation, and flushing.
1. This product is a weakly alkaline product, which has a certain coordinating effect on the modification of acidic soil.
2. Phosphorus can improve the differentiation vitality of plant flower buds, increase fruit hardness and shelf life, so the product can also be used in the early flowering and fruit forming period of crops; It is recommended to use an appropriate amount of product mixed with water spraying or drip irrigation fertilizer.
3. The phosphorus content in the product is high and easy to be absorbed, and the effect is better when used in the early stage of crop growth.
————————————————————————————————————————
Attention
This product can be mixed with neutral acidic pesticides, but not with alkaline pesticides. Do not mix with fertilizers containing calcium or magnesium to avoid precipitation.
This product is non-toxic and harmless, stored in a cool and dry place, and is easy to absorb moisture and agglomerate in the air after opening, but it does not affect the effect.
Spraying should be applied on the plant, the middle of the leaf, especially on the back of the leaf is easier to absorb.

Useage & Doseage
Flushing: seedling stage 15-18 (kg/Acre) growth period 18-30 (kg/Acre) fruiting period 30-60 (kg/Acre)
Drip irrigation: seedling stage 12-21(kg/Acre) growth period 18-30(kg/Acre) fruiting period 15-30 (kg/Acre)
Due to the complexity of crop nutrient deficiency and fertility tolerance, as well as the different soil structures and fertility in various places, the above usage and dosage are for reference only, and the specific dosage should be recommended by local agricultural technicians.
