Acid soil management – 5cm rule for soil pH testing

While previous acid soil testing practice was to not test as deep, new research, has identified greater acidic layering, where crop roots remain under the soil not benefiting from the full potential of amelioration. In this episode, we talk to Mark Richards from NSW DPI, and grower Andrew Lord about the new 5cm rule for testing soil pH. It allows the hidden acidity in lower layers to be recognised and treated, giving growers increased productivity and profit.
