The key aim was to compare the rate of lime movement down the soil profile and the change in pH down to a depth of 30cm.

The focus was on being able to rip and inject lime to depth, to attempt to alleviate the acidity and aluminium toxicity that resulted from the low pH.

To evaluate the response of eighteen barley lines for grain yield, grain quality and malting quality to changes in soil pH (due to liming).

The experience from trial work with TM21 in Canada and Vietnam has been that farmers have been able to reduce some of their inputs as well as maintain or increase their yield. BEST Australia set up a long-term trial at the Liebe Group Long Term Trial Site (LTRS) comparing fertiliser rates at three different input levels. This trial will continue over the next few years. During that time, BEST will be evaluating the trial at LTRS to show that fertiliser efficiency increases by using TM21 in Austr

Trials from over four years are examining different rates and timing of application of Bioprime, a liquid soil amendment which changes soil microbiology. The aim is to relate measured plant growth and yield improvement to changes in microbial populations in the soil around roots, and to show how these changes and different ways of applying nitrogen (N) impact on soil carbon accumulation.

To develop lucerne cultivars, specifically for the southern Australian cropping districts, that are compatible with existing farming systems as well as being productive and persistent. The breeding program is focusing on improving tolerance to acidic soils, persistent grazing and establishment with companion crops

To determine if various farm management techniques improve the storage of out-of-season rainfall and whether this leads to improvements in crop growth and/or yield.

To determine if various farm management techniques improve the storage of out-of-season rainfall and whether this leads to improvements in crop growth and/or yield.

To investigate if increasing soil organic carbon (SOC) increases N₂O emissions.

To test the interaction between wheat variety and seed size on the ability to emerge from deep sowing.

To compare Flexi-N timing especially for late protein boost application in wheat.

To investigate the composition of the free living nematode communities in Australian grain-growing soils; determine whether the community responds to different organic matter inputs and to various tillage and stubble management regimes; and decide whether nematodes are a useful indicator of soil health.

To determine the suitability of a range of sub-tropical perennial grasses to the medium rainfall zone of the NAR.

To understand how a range of pasture types combine to form a whole farm feed supply.
