Craig Thompson bought a WEEDit precision sprayer seven years ago and says it has become a crucial tool for summer weed control... A stark drop in growing-season rainfall in WA's northern wheatbelt means growers have to get crop roots much deeper into the soil profile to access moisture.. Craig says that wheat-on-wheat, with the aid of Clearfield wheats, has simplified the system and allowed him to concentrate on the single most important element - holding on to every drop of rain that falls...

The project has shown how the practice of SSM can deliver large, consistent and recurring increases in the yields of cereals, canola and pulse crops grown on Sodosol soils across the HRZ of Victoria... The practice was developed to overcome crop yield constraints caused by dense clay subsoils that are widespread across the HRZ. Low aeration in the clay limits deep root growth into the subsoil and this has been identified as a cause for the generally disappointing crop yields in the Victorian HRZ. Earlier research demonstrated how SSM can transform the physical properties of the clay layers... For sites with the 1/2 SSM treatment (6 site x seasons), the commercial wheat crop yielded an average of 6.2t/ha, the full SSM 9.7t/ha, and the 1/2 SSM 8.8 t/ha (42% response).This was surprising and suggests that this lower rate of manure incorporation will also give increases in grain yield...

The three elements phosphorus (P), copper (Cu) and zinc (Zn) were shown to have good residual values for crop production on a range of soils throughout the Western Australian (WA) cropping region... We now believe that future experiments should be carried out on new land and radioactive isotopes should be used to determine the proportions of P, Cu and Zn accessed by no-till crop roots from between and in crop rows... Future studies in existing no-till paddocks could be undertaken using isotope studies to determine the proportion of P, Cu and Zn accessed by no-till crop roots between and in crop rows...
