Regen ag in the low rainfall Mallee with Gupta Vadakattu – SA, VIC, NSW
In this Mallee Sustainable Farming (MSF) podcast, Gupta Vadakattu explains the findings from the first phase of the ‘Regenerative opportunities for building resilience in low rainfall farming systems’ project in the low rainfall regions in southern Australia. He explains what regenerative agriculture is and how it operates in low rainfall regions. The findings so far indicate that it is possible to achieve soil and system health, productivity and profitability in these regions. Appropriate management practices that increase soil biological functions include reducing tillage, retaining stubble and diversifying crops. Gupta discussed the use of artificial fertiliser inputs to maintain microbial activity in low rainfall, sandy soils to increase microbial activity. The project also found that grazing crop residues removes soil carbon. Grazing practices need to be modified e.g. by increasing crop diversity. Carbon is the major energy for soil microbes so crops are crucial for maintaining and enhancing carbon in soils. While this podcast was produced for the Mallee regions, the finding would be interest to farmers in other regions (14 September 2022) [17:27].#
This is a carefully curated database of important soil resources. The data base is not exhaustive but rather a library of the resources we believe are the most useful for the audience. Each resource has been added after careful consideration against our selection criteria, including but not limited to its scientific validity, accessibility, and readability. The library generally does not include most academic research papers but may include some open-source papers written in accessible English.
