Doug is a member of the APS Sutherland Group. Over the years, he has learnt a lot about soil. In his talk, he will he will get down to the basics – what he calls “Dirt for Dummies”.
We will learn about:
The different roles of top soils and subsoils.
The structure of soils and how it affects the ability of plants to take up water and food.
The chemical elements that are in the soil and how they become available to the plants.
The importance of the six factors that govern the soil’s ability to provide the nutrients that plants need - soil moisture, soil air, soil life, soil temperature, nutrient interactions and soil pH.
The importance of looking after the tens of millions of creatures that live in the soil in your backyard.
The role that bushfires play in the fertility of the soils in our bushland.
How to determine the type soil you have in your backyard and its pH value.
This is vital information for all gardeners.
