To assess the effectiveness of a range of soil ameliorants.

To use six different labs (Soil Food Web, CSBP, APAL, AgPath, Microbwise and Solvita) to analyse soil microbiology on six different properties across Kangaroo Island.

Ten paired monitoring sites were selected to measure soil carbon to 50 cm at strategic locations across the Island with consideration of rainfall, soil type and land use (perennial pasture and continuous no-till stubble retention cropping) compared to annual pasture. Common soil carbon tests were analysed to establish guides for the soils in the region.

Ten paired monitoring sites were selected across the Island with consideration of rainfall, soil type and land use (perennial pasture (Kikuyu) and continuous no-till stubble retention cropping) compared to annual pasture (clover and annual grasses). Soil pH was monitored down to 50 cm.

Farmers usually collect top-soil (0-10cm) samples when determining if they need to lime, but soil pH can be quite variable down the soil profile. Will a single sampling depth show up this inherent variability?

To investigate a spader machine for lime incorporation.

The spader trials were set up at several sites ranging from 0.5 ha to whole paddocks. The growers wanted
the spader to incorporate clay, lime and/or organic matter, or just improve the friability of the soil.

To understand the impact of differing wheat stubble loads on the establishment of canola under a range of locally relevant sowing practices.

This project will provide information on within-paddock variation in soil pH and related soil properties, in different regions of the High Rainfall Zone (HRZ).  To do this, we will map the horizontal and vertical variations in soil pH across 10 cropping paddocks in the Victorian HRZ. This will demonstrate to farmers how soil pH varies spatially and the economic benefits of targeting management of soil acidity to different zones within each paddock.

• Conduct 197 in-paddock surveys in both 2019-20 and 2020-21 to identify the composition of summer weed species present across the GRDC Western region covering the 6 eco-agricultural zones.
• expand the understanding of WA’s current in-paddock summer weed flora
• better inform possible future initiatives on identification and management of summer weeds

To determine the effect that nitrogen applied to a barley crop that ‘hayed off’ has on wheat sown in the subsequent season.

• To investigate whether barley varieties vary in their tolerance to scald.
• To compare different management strategies for controlling scald in different barley varieties.

To compare two new Rhone-Poulenc seed dressing treatments against existing products with and without Trifluralin.

To assess seeding rates in wheat and barley for optimum production and grain quality.

To assess seeding rates in wheat and barley for optimum production and grain quality.

• To investigate the efficacy of several commercial snail baits on juveniles of the four pest snail species, and assess the effect of bait size and density on mortality.
• To conduct preliminary trials to investigate the usefulness of caffeine and Perlka as additional snail management tools.

To compare early lines of canola for selection in the districts located around Minnipa (SA), Walpeup (Vic) and Condobolin (NSW).
