Western Australian grain growers are set to reap the rewards of a significant investment in new soil nutrition research that will boost crop production and reduce fertiliser costs.
Claying involves adding and incorporating clay-rich subsoil into water repellent topsoil to overcome the repellence.
Agricultural lime is any product that is used to increase the pH of soil. In Western Australia, the three main sources are limesand, limestone and dolomitic lime.
Carbonate from calcium carbonate (or magnesium carbonate) neutralises acid in the soil.
A small decrease in soil pH represents a large increase in soil acidity.
Convert to 100% neutralising value (NV) for equal comparison and discount to allow for differences in particle size and speed of reaction.
Soil acidity is a major constraint to farming in Western Australia.
