Try these new decision support tools to do better in the HRZ

Making fertiliser decisions can be difficult. Paddocks in the HRZ have high yield potential. Actual yields often fall short even in high input cropping systems.
Fertiliser decisions in the HRZ:

Under-fertilising appears to be a major cause of yield gaps in the HRZ.
You get the best return on nitrogen (N) investment with […]

Test first, then time Nitrogen fertiliser to reduce losses

Optimal timing of Nitrogen fertiliser applications can maximise crop uptake and reduce losses to the atmosphere. Soil Nitrogen (N) dynamics in Victoria show some big differences between regions. High rates of N losses recorded from soils in the High Rainfall Zone (HRZ) emphasise how important timing of N applications can […]

Reducing Nitrogen losses in the High Rainfall Zone of Victoria

Strategies to reduce Nitrogen (N) losses in Victorian High Rainfall Zone (HRZ) cropping systems are getting clearer.
Recent research in south western Victoria examined rates of N applied, placement of fertilisers and nitrification inhibitors. This work is part of the national agricultural nitrous oxide research program, supported by the GRDC.

Subsoil manuring provides long term N supply

Some growers have been able to reduce N inputs for at least three years following the placement of manure into the subsoil. Trials in Victoria’s High Rainfall Zone by Southern Farming Systems are showing promising signs of multiple benefits from subsoil manuring.
Originally, subsoil manuring was primarily for improving the […]
