Soil

Our thinking about soils and ‘soil health’ has come a long way in the past decade — soil is not there simply to support plants and their root systems; it’s a dynamic, living environment and a vital farm resource in its own right.

As the science of soil health rapidly changes and expands, AWI collaborates with industry experts and supports research and develop initiatives to ensure Australian woolgrowers have access to the latest best management practises.

Healthy Soils – Making More from Sheep Module 6

This module is designed to help sheep producers maintain healthy and productive soils. Within the module there are resources to help woolgrowers understand the soil and tools to help woolgrowers manage the health of their soil and also work out new management practises to enhance the health of the soil.

More than any other farm resource, soil health is about protecting and building up the capital so that we, as well as future generations, can continue to live on the interest. No amount of technology, genetics or grazing management will protect a business in the longer term if that business is depleting the soil resources.

Having healthy soils involves managing soils according to their capability, making the right fertilizer decisions, implementing solutions for problem soils, maintaining ground cover, and looking after the soil biology.

Phosphorus, nitrogen and potassium are essential elements for all living organisms.

AWI research investments target more efficient use of both natural and applied soil phosphorus to:

  • Promote efficient use of phosphorus in pastures.
  • Better match soil phosphorus levels to pasture stocking rates.
  • Reduce woolgrowers' cost of production by reducing phosphorus fertilizer input costs.
  • Minimise phosphorus leaching into waterways to reduce the environmental footprint of wool, and biodiversity losses from poor water quality and algal blooms.

AWI projects

AWI invests in significant projects that have a range of objectives to enhance the health of the soil and efficiency of the management practises of woolgrowers.

P-efficient Pasture Systems
The project will identify new legumes and other pasture species that have a reduced phosphorus requirement and can adapt to variable climates. To accompany this result, the project aims to develop methods to estimate residual phosphorus and provide guides for the optimal phosphorus requirements for some of the new novel legumes. Develop low-phosphorus pasture systems that slow the rate of phosp...

The project will identify new legumes and other pasture species that have a reduced phosphorus requirement and can adapt to variable climates.

To accompany this result, the project aims to develop methods to estimate residual phosphorus and provide guides for the optimal phosphorus requirements for some of the new novel legumes.

Develop low-phosphorus pasture systems that slow the rate of phosphorus accumulation in soil. Accumulation of organic phosphorus in soils is a major inefficiency in fertilized pasture systems.

Dryland Legume Pasture Systems
This project is trialling newly obtained and collected legume species to meet the changing climate and production needs of mixed farmers (livestock and cropping producers). They are being trialled in areas previously not idenitfied as "ideal" and are providing positive results. New legume species including Biserrulla, Serradellas, Clovers, Vetchs and Medics will be recommended after trialling t...

This project is trialling newly obtained and collected legume species to meet the changing climate and production needs of mixed farmers (livestock and cropping producers). They are being trialled in areas previously not idenitfied as "ideal" and are providing positive results.

New legume species including Biserrulla, Serradellas, Clovers, Vetchs and Medics will be recommended after trialling to support mixed farming and livestock enterprises.

These legumes will offer options to producers with previously unproductive land, non-wetting soils and those experiencing dryer seasons as a result of climate change.

Producer guides and a seed commercialisation option is being developed to progress adoption.

Acid Soils
Soil acidity and associated high levels of aluminium and manganese can significantly reduce pasture productivity. In partnership with the NSW Department of Primary Industries, AWI funded research determined the cost effectiveness of applying lime to acid soils for wool production. The MASTER (Managing Acid Soils Through Efficient Rotations) project ran for over 10 years, investigating the econo...

Soil acidity and associated high levels of aluminium and manganese can significantly reduce pasture productivity.

In partnership with the NSW Department of Primary Industries, AWI funded research determined the cost effectiveness of applying lime to acid soils for wool production.

The MASTER (Managing Acid Soils Through Efficient Rotations) project ran for over 10 years, investigating the economics of incorporated lime to manage surface and subsoil acidity, pasture and sheep productivity.

A second project looked at the economics of surface-spread lime and phosphorus to manage soil acidity, pasture and sheep productivity in non-arable areas. Until this project, very little information was available on the effectiveness and economics of surface spread lime to reduce both surface and subsoil acidity.

Phosphorus application
The Five Easy Steps tool combines years of research, data and information into five steps for woolgrowers to follow when making decisions around an investment in phosphorus. Up to 30 per cent of soil tests show soil phosphorus (P) levels are above optimum. Many woolgrowers could justifiably decrease P applications without impacting on production.

The Five Easy Steps tool combines years of research, data and information into five steps for woolgrowers to follow when making decisions around an investment in phosphorus.

Up to 30 per cent of soil tests show soil phosphorus (P) levels are above optimum. Many woolgrowers could justifiably decrease P applications without impacting on production.

Five Easy Steps is available to help woolgrowers make more accurate decisions on P applications. The tool was developed by CSIRO and NSW Department of Primary Industries, with funding from AWI and Pastures Australia members.
