Research Question

What are acidification rates in topsoils and subsoils under local and modern farm practices? What are the most cost effective ways to ameliorate soil acidity and then maintain good soil pH by maintenance liming?

Research Information & Objectives

What is being done?

SFS is a collaborator in this PIRSA led soil acidity project across the southern grains region.

This project will provide the necessary resources to collect much needed long-term data from lime experiments across SA and southern Victoria.

The knowledge generated will:

  • review acidification rates in topsoils and subsoils under local and modern farm practices, including estimates of lime movement down the soil profile,
  • revise lime recommendations, acidity management practices and extension aids,
  • review long-term crop profits for optimised soil pH profiles, and
  • extend and communicate findings to grain growers.

This project allows continuation of two subsoil acidity trials at Rokewood and Stawell aimed at addressing acidity in the subsurface, lime comparison work at Mt Mercer that was part of a pHD project, establishment of a long term trial at our Streatham research site, continuation of the Westmere trial that was established in 2014 and monitoring of a liming demonstration site at Inverleigh.
