Agronomists in the South Australian and Victorian Mallee say that using soil testing to optimise crop biomass and soil nutrition decisions can help avoid topsoil erosion and yield losses. Research shows that losing one millimetre of topsoil can result in yield losses of between one and six per cent.

Leading crop researcher Dr James Hunt is exploring a new concept called the nitrogen bank, with promising early results

A long-term trial undertaken by the Western Australian No-Tillage Farmers Association has not only provided significant insights for growers into the principles of conservation agriculture practices, but also added to the international science base and trained future systems-thinking scientists.

Mungbean crops typically require N to maximise yield, but recent research has found that mungbean crops will not respond to applied N fertiliser under a wide range of field conditions.

Demonstration sites over two seasons across Western Australia have shown that little consistent evidence that crop varieties respond differently to nutrition strategies. However, results were highly variable and season and location specific highlighting the importance for growers to consider adjusting their fertiliser strategy throughout the year to increase yield or improve grain quality, and ensure inputs are not wasted by the crop.

University of Adelaide PhD student Jacinta Dockerill is challenging the salt index approach which relates a fertiliser’s toxicity risk with its impact on salinity measured in a laboratory.

Phosphorus fertiliser is one of the most important and often limiting nutrients in agricultural production. A new project is testing the potential to improve crop nutrient uptake by dual banding phosphorus so it is co-located with moisture in the deeper soil layers.
