The MZTRA has concentrated on no-till throughout its cropping program since it’s inception in the 90’s. Lindsay and the board are looking at creating efficiencies with lower energy systems. One area of this is precision agriculture. They have mapped the soil over the farm done to 1:5000 which gives them very detailed soil zones. Nicole is working with Lindsay to create VRT maps to use their inputs more efficiently such as using more fertiliser on higher yielding areas and vice versa on low yielding ones.
Also in this area they are utilising modern military knowledge to fly Unmanned Aerial Vehicles (UAV’s) in the form of a toy radio controlled plane to fly over paddocks to take infrared photos. They are then using these to look at crop densities for the need to apply fungicides. This technology could also be used to map nitrogen levels in crop.
Lindsay and one of his summer students have been trialling cell grazing in lucerne pastures compared to native prairies. They are in the second year of this and will use the cell grazing for one more year then will crop those paddocks for a number of years. The aim is to again look at the low energy input that the lucerne has contributed in the form of nitrogen. The returns will be examined in $/ha and the energy inputs and outputs.
