Removing Heavy Metals From Your Soil

Removing Heavy Metals From Your Soil

Macquarie University run a program called Vegesafe which aims to inform the community about metal and metalloid contaminants in their garden soil through their free soil metal testing program.

If you have heavy metals in your soil, you can help to remove them by adding zeolite granules.

Zeolite captures heavy metals, radionuclides and a wide range of chemicals found in soil by magnetic attraction. Heavy metals and chemicals are drawn into the structure of the zeolite where they are permanently bonded.

Australian organic certified zeolite is the finest quality agricultural grade zeolite in the world.

No other zeolite in the world performs as well in the soil. This is because Australian zeolite is 305 million years old and is so hard that it doesn’t break down in the soil. Younger zeolites from South East Asia, New Zealand, America and Europe are only about 250,000 to 100 million years old. They are geologically ‘soft’ and break down easily, making the soil gluggy.

Zeolite Encourages Vigorous Growth

The grade of zeolite recommended for general gardening is a blend of particle sizes from 0.5 mm to 2.2 mm. The fine particles have the highest cation exchange rate which improves soil fertility. The larger particles help to improve soil structure and water retention. When zeolite is added to your soil it works continually to improve growth: ‚

  • improves fertilizer efficiency ‚
  • improves water retention and distribution ‚
  • improves soil structure and porosity ‚
  • improves plant growth and yields ‚
  • its high cation exchange capacity improves soil fertility ‚
  • helps to remediate soil salinity ‚
  • slightly alkaline pH level helps sweeten acid soil ‚
  • absorbs ammonia and releases it to plants as nitrogen 130 Zeolite in the Garden ‚
  • traps and captures heavy metals and some chemicals ‚
  • geologically hard and stable, it lasts forever in the soil

A Storehouse for Nutrients and Water Zeolite is not a nutrient, it absorbs and stores nutrients in its structure then releases them to the plants when needed. Zeolite prevents nutrient loss through leaching. If you use manure, zeolite will capture the ammonia and release it to plants as nitrogen when needed. Zeolite helps plants to survive in dry conditions. The granules absorb and store water then release it to the plants and, once again, only when it is needed. For the best performance, add zeolite to the root zone then fertilise and water it through.
