Dry weather has meant many growers did not put in a crop this season. Crops that have gone in have struggled to establish. This has left extensive areas of bare soil exposed to wind erosion. Wind erosion is not always a big dust storm. Sometimes large particles roll across the […]

Root systems that respond to banded fertilisers

Crop varieties that can exploit fertiliser placed in bands could be crucial to future cropping yields and fertiliser use efficiency. Many of our cropping systems are slowly running down the native soil fertility. Ongoing cropping in these soils could depend more and more on nutrients placed into the soil as […]

Deep Phosphorus fertiliser trials in NSW

Deep phosphorus (P) placement to improve crop productivity is being investigated in the central west of NSW, at Gilgandra and Nyngan. Led by Dr. Mike Bell (QAAFI), the trial investigates how deep P placement affects the fertility of the subsoil, and the economic effectiveness of deep P placement. The work […]
