Comparing the influence of organic matter and fertiliser inputs on soil organic carbon and grain production

To identify on-farm management strategies to increase soil organic carbon (SOC) and quantify any associated risks and benefits in a grain production system.

In this trial the Facey Group wanted to determine whether:

  1. Altering inputs to increase plant biomass would subsequently increase soil carbon and
  2. Amending soils with compost would increase soil carbon storage or provide agronomic benefits.

Comparison of different green manure crops as tools for renovation cropping and evaluating economic benefits at Mullewa on a heavy soil

This research determines to assess the benefits (economic and environmental) of a green manure phase under current cropping systems in areas with a poor nutritional status. 

To evaluate crop types and incorporation techniques to rejuvenate poor performing soils using a green manure phase, as well as to identify and evaluate the potential longevity of benefits on a heavy loam soil in Mullewa, Western Australia over five years.

Does increasing soil organic carbon alter nitrous oxide emissions?
  • To increase understanding of the interaction between increasing soil organic carbon and greenhouse gas emissions. In particular to quantify the influence of soil organic carbon on nitrous oxide and methane emissions in a grains cropping system.
  • To determine whether increasing soil organic carbon lowers the amount of nitrogen fertiliser required for grain production.

The profitability of green manuring - discussion paper

This paper assesses the economic benefits of green manuring and the potential costs. It also investigates the circumstances in which green manuring will be profitable and those that result in losses to growers.

The short term effect of different soil treatments on organic carbon and barley yield on a sandy soil

To assess the effects of physical, chemical and biological soil manipulation (or inputs) on soil organic carbon in relation to changes in long term crop yields and quality.
