Why compost alone might not be enough to save your garden
In short: Many Australian soils suffer from a chronic lack of phosphorus. This video explains why typical organic matter isn't a complete fix and how to identify and rectify nutrient deficiencies for stronger plant growth.
Phosphorus is essential for cellular development, plant structure, and root strength. Because many soils, such as those found in Brisbane, are heavily weathered and phosphorus-deficient, simply adding compost is often insufficient to reach necessary levels.
The video explores practical remediation, such as applying super-phosphate at a rate of two handfuls per square metre to establish a baseline. Once established, gardeners can maintain levels using manures, composts, or organic phosphate derived from guano.
