PurÖSil_Siliceous Earth


Shipping : 3-5 Business Days


PurÖSil s processed siliceous earth mined from sedimentary layers deposited millions of years ago in a fresh water lake. It is light weight grains like in appearance, very porous and comprises siliceous fossils of plant algae. It consists primarily of amorphous silica, a highly beneficial nutrient for plants as it strengthens cell walls and leads to healthier, stronger and more robust plants Growth.

Purosil is used as a high performance soil amendment / conditioner to provide plant available silica and improve cation exchange capacity, improves porosity and drainage of soil and promote the health of the soil's root system. The addition of PurÖSil to soil helps to promote the healthy growth of living plants. The intricate pore structure of diatoms keeps the pores in the soil open and controls the water supply to the roots, holding and releasing moisture when required. The improved structure oxygenates the soil and helps break up heavy clay.
