In order to provide safety food, soil improve agent also has to be safe. Porous Alpha is compliant “Environmental regulations on contamination of soils” which was established by Ministry of the Environment of Japan.
The utilization of Porous Alpha doesn’t have any problem related to heavy metal and toxic product to use it as the soil including mixing with soil.

Result of leaching test based on “Environmental regulation on soil contamination“, (23 Aug. 1991, Ministry of the Environment)

Analyzed by Tottori health association, Jan. 2008)

Result of leaching test in the frame of environmental regulation in Japan,2008

Analysed heavy metal and physico-chemical on the fruit of Tomato and Green beans which is cultivated by the soil including Porous Alpha.

The result show it doesn’t has any problem for adjusting CODEX regulations and EU regulation in both condition between with Porous Alpha and without Porous Alpha.

Please check their detail from following tables.

Target crop: Tomato

Cultivation period: Sep,2016 to Feb,2017

Farm:Experimentation site in ORMVASM

Analysis organization: Labomag

Analysis method: Sampled 9 fruits in each condition between with Porous Alpha and without Porous Alpha.
In each conditions, its were cultivated (1)normal irrigation volume (2) 30% saved irrigation volume (3) 50% saved irrigation volume. Fertilizer used same amount for every conditions.

Number designated in tables are result of average on 9 samples between 2 conditions.
