Welcome to Vandergraaff Soils Horizons

All land use impacts on the soil and, most often, on the surrounding natural waters. Led by one of Australia’s most highly regarded soil scientists Robert van de Graaff, van de Graaff & Associates specialise in offering comprehensive soil and water assessments and recommendations for sustainable land-use.

In approaching soil and water management projects, van de Graaff & Associates apply the all-encompassing Dutch philosophy:

- All land is valuable
- All land can be improved and made productive
- A clean environment is necessary for community well-being.

These principles have been successfully applied in Australia and iinternationally for more than 30 years.
