How good is your soil? Are your attempts to improve it working? Has it got more earthworms than this time last year? More or less groundcover? Better or worse structure?
One way to keep track is to use the ingenious Soil Health Card, developed by farmers, agriculture scientists and TAFE teachers in the Northern Rivers region of NSW, but useful in all climates.
By using simple homemade tools, such as penetrometer (a piece of fencing wire), an infiltrometer ring (a piece of PVC pipe) and a wire quadrant (a coathanger), along with a pH kit, a spade, a jar and a few other items, farmers and gardeners can conduct a fairly thorough analysis of their soil.
You conduct the tests, write down your scores on your Soil Health Card, and keep it as a record that can be referred back to.
