The Coorong Tatiara Local Action Plan is currently delivering a suite of projects in the area of Sandy Soils and Soil Innovation.
We have developed the Project Concept 'Livestock Production on Sandy Soils - Lets make the Bucket Bigger', and are actively working with our partners to realise the ideas outlined in this document, which would deliver both agricultural production and land management benefits. Please click the link to learn more.
These projects are supported by the Australian Government’s Region Land Partnerships initiative of the National Landcare Program, South East Natural Resources Management Board levy funding, & SA Murray Darling Basin Natural Management Board.
We are also very pleased to welcome Meat and Livestock Australia as a project partner.
Soil pH testing at the Yumali Soil Constraints Farm Walk
Improving soil health across our landscape will result in a number of benefits including;
- Increased livestock feed production
- Improving the ability to capture rainfall where it falls
- Improved resilience to dry conditions
- Reduced wind erosion
- Reduced recharge to groundwater, delivering dryland salinity benefits
- Understanding & improvements in; groundcover, soil pH, carbon, structure, water holding capacity
Identifying & treating soil constraints to maximise plant access to all of the available moisture & nutrients in the soil profile is the key to unlocking these benefits.
Soil constraints we are interested in exploring include, but are not limited to
We are interested in transferring innovations to sandy grazing country to test soil measurements
and amelioration techniques including, but not limited to

Improving Sandy Soils through understanding soil pH and soil potassium
The Improving Sandy Soils through understanding soil pH and soil potassium status report covers use of a range of soil testing technologies on a sandy – sandy loam, continuously cropped paddock in the Yumali – Ki Ki area;
- Use Veris Machine Mapping technology was used to identify spatial variation in pH,
- Use of grid sampling to explore mapped spatial variation in Potassium, Phosphorus, and Sulphur.

Kym and Katie IÁnson's philosophy is to grow healthy profitable crops but to do this they need to overcome soil constraints an match inputs to potential production. Includes information on the Veris Machine used to map the pH of soils.

Upper South East Sustainable Soils - EM38 Mapping for Clay Finding
The Upper South East Sustainable Soils – EM38 Mapping for Clay Finding Report covers use of EM38 soil mapping technology to spatially locate clay and other soil properties below the soil surface to aid in soil management decision making.
- EM38 technology works better in some regions than others to locate clay. The spatial data generated can then be utilised to reduce costs when looking to ameliorate soils,
- In situations where clay isn’t detected, the EM38 still relates strongly to production, and has the potential to be utilised for other soil management strategies.
Three sites were EM38 mapped as case studies in this report. Recommendations, products, and findings drawn from the EM38 mapping data varied between the sites and include;
- Identification and differentiation of sites within paddocks that were suitable for clay spreading, delving, or ripping. This differentiation allows cost effective application of mechanical soil amelioration techniques to be applied in the right location.
- Effective location of clay pits for clay spreading.
- Provision of a GIS based EM38 paddock map to the machinery operator can be used to provide depth to clay information to inform operator depth control in a delving or ripping situation to maximise contractor, time and horsepower efficiency.
- On deep sandy soil sites, identification of rock in the paddock to be avoided when ripping.
- Relationships established between EM38 results and NDVI pre grazing suggest soil properties are driving feed production.
Soil Moisture Probes

Precision Pasture Decisions Project – Field, South Australia
The Precision Pasture Decisions Project was delivered in 2019 in the Field area east of Meningie.
The project included installation of monitoring equipment including;
- Field location weather station with rainfall, wind speed and relative humidity – updated every 15 minutes.
- Soil moisture probes under two different perennial pasture systems; Veldt Grass and Lucerne.
Local growers shown how to access weather and moisture probe data, and shown this data has the potential to assist in improving decision making under different climatic conditions. This was provided 1:1 and at a Pasture Farm Walk held on the 25th of June with 18 people in attendance.

Grain growers can save considerable dollars by making use of on-farm agricultural lime, rather than freighting lime from afar.
