Aerating Your Soil with Perlite

One of the biggest problems we have with soil in Australia is one of compaction.  Agricultural soil becomes compacted through over-tilling, over-cropping and use of machinery.  Garden soil becomes compacted from the building process and then us walking on it when wet.  Soil in a natural bush environment also becomes compacted as a result of various processes, including water saturation.

If soil is compacted, then there are a reduced number of pore spaces available for water and air infiltration.  The soil will drain very slowly.  It may become anaerobic.  There will be little root penetration.

In short, a compacted soil is not great for growing plants in!

Zeolite

Zeolite is currently high on the list of soil amendments I use, following a close behind good old common or garden compost.

Soil Amendments

For me, the core of sustainable agriculture, horticulture, or just plain gardening, is the soil.

Caring for the soil, increasing it's carbon, nutrient and water holding capacity, and reducing or stopping practises that lead to soil degradation, should be the foundation block upon which any sustainable land management practise is built.
