As a multicomponent, in addition to nutrients is phosphorus (P2O5), there are other nutrients necessary for plants and soil improvement such as lime (calcium), mica, silicon, copper, boron, zinc , molybdenum, cobalt ... Lao Cai alkaline phosphate is alkaline (pH: 8-8.5), non-toxic, insoluble in water but only soluble in acidic environment due to root release, so when fertilized The field is not washed away, providing nutrients for the crop from the beginning to the end of the crop. If the plants are not used up, the substances in Lao Cai phosphate fertilizers are still retained in the land provided to the crop in the next season. Lao Cai fused phosphate fertilizer is good for most crops such as rice, maize, sweet potato, cassava, beans, peanuts, vegetables, industrial crops such as rubber, coffee, cotton, sugarcane mulberry and other kinds of fruit trees, forest trees, etc. Lao Cai fused phosphate fertilizer is suitable for many areas, especially for acidic, lowland, sloping land, sloping land. It is more effective than other phosphates. Crop fertilizers are not only high yielding, good quality of agricultural products but also increase pest and disease resistance and weather severity. Lao Cai will reduce acidity, reduce moss, do not make hard soil soil to improve the soil to make porous.

Fertilizer: The amount of fertilizer depends on each type of plant, on each type of soil. For rice and short-term crops, the average input is 17 - 25 kg / sao. For perennial crops: coffee, tea, orange, tangerine, longan, litchi, etc., when planting basal fertilizers 1-2 kg / tree, fertilizing 0.5 kg / tree every year. It is important to apply nitrogen, phosphorus, potassium balance to ensure crop yield and quality of agricultural products. How to apply: For rice and short-term plants is best to fertilize, but with perennial crops dig around the root of the tree foliage, spread fertilizer and fill the soil.
