Agricultural land rehabilitation

Semi-arid and savannah regions form the majority of Queensland and Australian pastoral enterprises. Rainfall deficiencies and inherently nutrient poor soils are the primary limiting factor to productivity.

It begins with soil biological communities
The University of Queensland has partnered with BHA and AgForce to develop innovative approaches to address declining soil fertility by capitalising on Australia’s natural biological resources. Fundamental to improving soil fertility and land productivity are soil biological communities (SBCs). By placing the emphasis on SBCs as the productive component of soil fertility we can maximise seasonal SBC biofertilisation.
SBCs provide an environmentally sound basis for improving biofertilisation
  • SBCs accelerate the rehabilitation of unproductive land
  • Biofertilisation leads to increased productivity
  • New and innovative technologies are developed with SBC inoculum
  • SBC biofertiliser can reinvigorate soil function
  • Biofertilisation results in long-term productivity gains

 BHA PARTNERSHIP RESEARCH FOCUS

 

Real future impact for farmers can be achieved

BHA supports an innovative approach to maximising soil fertility

Research is aimed at SBC biofertilisation

Outcomes are directed at the real need for increasing land productivity

Seasonal biofertilisation (especially nitrogen) can be targeted

Farmers can predict peak SBC inputs

On-farm trials will provide examples of the effectiveness of SBC biofertilisation
