Many growers in lower rainfall areas of the Wheatbelt are looking to minimise risk and increase efficiency. Growing your own nitrogen (brown manuring of legume pastures) or increasing soil water and decreasing weed/disease issues through chemical fallows are becoming more common. This trial would like to compare the economics of these systems. Legume pasture treatments of Lupins and a Lupin/Vetch mix will be compared alongside a chemical fallow with soil nutrients and soil moisture being measured in order to determine potential yield of the following crop. As this is only a one year trial, the potential yield at seeding (determined by soil moisture), the inputs required to grow this (determined from soil testing at seeding) and pasture establishment costs/fallow chemical costs will be used to estimate the most economically beneficial system.
The project aims to compare the economic benefits of ‘growing your own nitrogen’ through the use of legume pastures (trialling lupins and a vetch/lupin mix) against the economic benefits of increasing soil moisture through use of a chemical fallow.
