Base fertilizer and additional fertilizer

coated compound fertilizer

Coated fertilizer consisting of nitrate-based compound fertilizer coated with a film material.
Typical products include "Long", "Ecolong" and "High Control". Depending on the ingredients, "413", "203", "250", etc., and "Total" is added to brands with trace elements.
Micro Long Total, a fine-grained "long total," is used for seedling growth.
Brands with "Super" in the name are sigmoid (S) types that suppress leaching for a certain period after fertilizer application.

chemical fertilizer

Compound fertilizers are made by mixing fertilizer materials and reacting them with heat to form granules, each of which contains fertilizer components such as chisso, phosphoric acid, and potassium.
There are phosphorous sulfuric acid systems and nitric acid systems containing nitric acidic chisso, depending on the chisso raw material, and NK chemical synthesis is available depending on the component.
In addition, "IB Kasei" and "CDU Kasei," which contain nitrate inhibitors and slow-release nitrogen as raw materials for chemical fertilizers, are chemical fertilizers with a long-lasting effect of nitrogen.
