Bentonite | Envirofert

Bentonite expands when wet, absorbing as much as several times its dry mass in water. Because of its excellent colloidal properties, it is often used in drilling mud for oil and gas wells and for geotechnical and environmental investigations.

The property of swelling also makes sodium bentonite useful as a sealant. Uses include making slurry walls and forming other impermeable barriers, e.g., to seal off a water well, or to line the base of landfills to prevent migration of leachate.

Envirofert is investigating the potential uses for reprocessed bentonite obtained from the construction industry as a effluent pond liner.

Wormacompost | Envirofert

Vermicomposts tend to contain a wider diversity of bacterial and fungal families, which means that they have the potential to enhance a wider range of soil environments than thermophilic composts as they are more likely to contain species that are active under any particular set of conditions than composts with a smaller range of families.


50/50 | Envirofert

The wormacompost appears to have encouraged good growth and improved health of our avocado trees and we are confident this will contribute to excellent future crop yields.. The addition of chicken manure to Envirofert's wormacompost provides a boost in Nitrogen, Potassium and Phosphate levels to stimulate plant growth.


Gypsum | Envirofert

Gypsum assists the stabilising and strengthening of soil structure by encouraging the small clay and silt particles to bind together to form stable soil aggregates. Calcium is vital for maintaining soil pH and an important component in cell wall strength and function thereby assisting root growth and development. Plants will show better root development and penetration thereby getting to the nutrients and water they need for growth.
