Slow Release Boron Fertilizer : 10% B + organic matter
Boron participates in many important physiological activities and is an important nutrient element necessary for crop growth and development and flowering. When the soil is deficient in boron, the crop will become thicker, brittle, deformed, and become dark yellow-green or purple-red spots, with short internodes and cork formation. The root system becomes thick and short, brown, and the root system is underdeveloped, and the growth point often dies.
Product features:
Produced by proprietary technology, the effective nutrient release period is 120 days, and the utilization rate is more than twice that of powdered boron fertilizer. With the application of the base fertilizer, there is no need to spray (rush) the work, that is, water saving and labor saving, one application can meet the needs of the whole growth period of the crop.
Division of soil boron supply capacity:
Very low: ≤ 0.25mg / kg;
