Product Details
When applied wilth Soratan, it is possible to reduce CO2 emissions by approximately 1 ton per 10 a (per rice paddy).
Anticipated Benefits
The following benefits can be obtained by installing Soratan.
- Reduction of chemical fertilizers (e.g., 50% reduction in komatsuna)
- Reduction of frequency of compost application (from annually to once every 3 years)
- Improvemeent in land utilization rate (mitigation of continuous crop failure → 1.5 times higher than before)
- Increase in added value and sales through environmental contributions
- Proxy acquisition and sale of carbon credits based on the amount of Soratan applied, and partial return of profits from the sale of the carbon credits
Differences from conventional biochar
Biochar in general is highly alkaline, and the upper limit of application is about 2% of the cultivated soil, especially for land that should be improved, such as rice paddy fields and immature soil. Spraying more than this 2% amount will cause the soil acidity preferred by crops (pH 5.5~6.5) to be exceeded, resulting in lower yields. In general, it is difficult to accurately spray large areas of farmland with a coverage of no more than 2%, and in some cases, for example, uneven spraying can result in reduced yields. In contrast, the acidity of Soratan itself is close to neutral. Therefore, no matter how much is applied, the soil acidity level that plants prefer can be maintained. It is unlikely to cause problems even if there is uneven spraying. Experimental results from our company and cooperating farmers have also confirmed the effect of improved yields.
