About This Product

■Reliable powdered charcoal

Although charcoal has been used in agriculture for about 20 years, there are still many inferior products on the market. About half of the charcoal is said to be waste wood charcoal, and while agricultural carbon has an internal surface area of ​​200 to 300 square meters per gram, waste wood charcoal has an extremely poor internal surface area of ​​8 to 10 square meters per gram. Not just any charcoal is fine. It is difficult to tell the difference between products, but the quickest way is to ask a trusted vendor about their physical and chemical properties (internal surface area).

■Features and effects

・Agricultural carbon has a fine porous structure and is particularly useful for adsorbing fertilizer components and for changing the physical and microbial environment of the soil as it has high water retention, water permeability, water permeability, and air permeability. ・Agricultural carbon increases soil temperature by around 1 to 2 degrees Celsius. - Adsorbs nitrate nitrogen and makes it available to plants without washing it away. -Especially effective in acidic soils, avoiding concentration problems caused by fertilizers. ・Compared to palm charcoal, it is black charcoal and has a lighter specific gravity, so it will not sink even if you put it in a cup.

■Amount of fertilizer applied Standard amount of fertilizer (per 10a)

・7-10 bags of apples, pears, grapes, and other fruit trees ・6 to 10 bags of melon, strawberry, eggplant, watermelon, tomato, onion, cucumber ・Flowers 7-10 bags ・6 to 8 bags of beans ・Garlic/potato 7-10 bags ・Rice, wheat, grass 6-8 bags ・It can be used at any time, but it is especially effective when used together when applying base fertilizer. ・Apply to cultivated land by surface spraying or streak spraying, and till the soil so that it mixes well with the soil. (It is especially effective when applied locally.) It can also be applied at the same time as any fertilizer. - If this soil improvement material is exposed on the ground surface, it may be washed away by wind and rain, and if it forms a layer in the soil, it may not be effective, so please mix it thoroughly with the soil.

■Raw materials used

・Hardwood ・Conifer
