About This Product

■Steamed

It is made by carbonizing rice husks and has a large number of fine pores (air pores) after the gas components contained in the rice husks are burned, making it a safe charred material that does not contain oil such as tar. The difference from charcoal is that it contains nearly 50% silicic acid (SiO2), which can be called earth, and also contains trace elements. It has an alkaline pH of 8 to 10, making it suitable for correcting the pH of acidic soil. In addition, the pH is alkaline due to the ash content in the charcoal, but when water is added or washed, it becomes slightly acidic, but this ash is a mineral that the rice plants absorb from the ground and is responsible for plant growth and fruiting. It is a valuable ingredient needed when

■Features and effects

・It combines the four major elements that plants need (sun, air, water, and soil). It has a dark complexion and absorbs solar heat well and has excellent heat retention. It is porous and has countless fine holes (20~80u) running both vertically and horizontally. If you calculate the surface area of ​​the pores, 1g of charcoal will be 330㎡. (For charcoal, it is 313㎡ per 1g.) ・High water retention and water permeability. The water retention capacity is extremely high at 680% by weight, but the water permeability is also good. (Once the water becomes saturated, most of the unnecessary water will be drained away.) ・It has a high silicic acid content (approximately 50% content) and has a light specific gravity. Since the soil is mainly composed of silicic acid, rice husk charcoal itself can be said to be high quality soil with a specific gravity of 0.1 (approximately 1/10th the weight of soil).

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

・General crops 30-50 bags ・For seedling raising, use 5-10% as appropriate. - 100 liters of content is equivalent to about 4 fertilizer bags or half a drum (about 6 tons). - 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. *Due to the nature of the product, it may be powdered and its volume may be reduced.
