Soil conditioning

(safety)

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.

Effect for fruit

Analysed heavy metal and physicochemical 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.
