[Efficacy]:
1. This product is designed and manufactured by YOSHIZAWA, using patented technology and high quality raw material. The formulas are scientifically designed and can bring out effect stably. This product is recognized by JA organization in Japan.
2. This product can provide essential elements such as Si, Ca, and Mg, and beneficial elements such as Fe, Mn, and B. These beneficial elements can prominently improve plants’ growth and control element deficiencies.
3. This product is rich in water-soluble Si and can supply Si quickly. Therefore, it can promote the forming of silicon cuticle in epidermic cells, obviously improve the epidermic cells’ flexibility, and enhance plants’ resistance to pests, lodging, and drought. Si also participates in the forming of nutrients-transporting channels, improving the transportation rate of nutrients inside plants and the accumulation of dry matter.
4. This product can effectively supply Ca, relieve physiological disease caused by Ca deficiency (apple bitter pit, tomato blossom-end rot, Chinese cabbage dry heart, rotting&death of growing points). This product is rich in Mg, and it can slow down the functional death of leaves, enhance photosynthesis, and accelerate the accumulation of nutrients.
5. This product has a pH value of 7.5 - 9.0. It can effectively relieve soil acidification, improve soil granular structure, enhance soil’s permeability of water and air, activate P in the soil and the absorption of P from roots, and provide a better environments for roots, increasing plants’ quality and yield.
[Applicable Crops]: fruit trees, vegetables, and field crops.
[Application]:
1. Fruit trees: for base fertilizer, use with organic fertilizer and compound fertilizer, 0.5 - 1 kg per tree; for topdressing: 0.5 - 1 kg per tree.
2. Vegetables: for base fertilizer, 300 - 600kg/hectare, can be mixed with other fertilizers.
Field crops: 15 - 75kg/hectare, can be mixed with other fertilizes.
