Characteristic
MAP,colorless crystal,is a high-concentration fast-acting fertilizer,suitable for a variety of crops and soils,especially suitable for crops that fit ammonium and phosphorus,as base fertilizer or top dressing, should be applied deeply.
This product is 100% fully soluble in water,suitable for the needs of various crops for nitrogen and phosphorus
elements,especially suitable for the use of base fertilizer and top dressing in arid and rainy areas.
————————————————————————————————————————
Function
1. Fast water soluble, suitable for various irrigation and fertilization systems;
2. It does not contain sodium and chloride ions, and the residue of other heavy metal ions is very low;
3. Contains ammonium nitrogen and phosphate phosphorus, which is easy to be quickly absorbed by crops.
4. It can meet the demand for phosphorus in the whole growth cycle of various crops;
5. Low alkaline fertilizer: PH4.2-4.8.
————————————————————————————————————————
Application
1. The product has high phosphorus content and is water-soluble phosphorus, which can be quickly absorbed,
so it can promote the root development of seedlings and have a quick effect on the early growth of crops;
2. Phosphorus can maximize root development and flower cluster formation, increase fruit hardness and shelf life, so the product can also be used in the flowering ,fruitlet and maturity stage;
It is recommended to use an appropriate amount of product mixed with water spraying or drip irrigation fertilizer
————————————————————————————————————————
Attention
MAP can be mixed with Urea, Potassium nitrate, Potassium sulfate and other water-soluble fertilizers, so as to match the nutritional needs of more plants in various growth stages.
Do not mix with alkaline fertilizer, so as not to reduce the fertilizer efficiency, such as the southern acidic soil to use lime, should be separated a few days before application, this product can be mixed with neutral acid pesticides, can not be mixed with strong alkaline pesticides, not mixed with calcium or magnesium fertilizers to avoid precipitation

Useage&Doseage
Foliar spray: 0.1~0.2% water soluble to promote strong flower development,optimize bud burst;
Drip irrigation: dilute 0.5~1% and dosage 30~60 kg/Acre to promote seedling development, leaf and branch scattering;
Seed fertilizer: dosage 15~30 kg/Acre; Base fertilizer: dosage 60~90 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.
