The micronutrients (ppm): B, Zn. Mn. Mn. Cu, Co ... Cu, Co ...
Supply nutrient phosphorus for plants (effective P2O5: 15-17% 17-19% 19-21%). It is essential to create the plant cells, promote germination, root development, increase the number and quality of seeds, tubers, fruits, etc. ..
It is water-insoluble fertilizers should limit leaching which dissolves in the fluid secreted roots, so suitable for many different soils, especially acidic, sour-lying, swampy indented, basalt soil, soil hilly, soils ...
Sour reduction, soil improvement:
- Calcium (CaO: 25-30%): Effect reduced sour, detoxify, reduce soil acidity, improving soil fertility and help increase plant protein synthesis and metabolism of nutrients.
- Magnesium (MgO: 14 to 18%): Effect reduced sour, acidic soil decontamination low as calcium, is essential to create the plant chlorophyll, which helps increase crop photosynthesis and synthesis protein, fat, sugar etc.
