Changing grazing and land management practices to bolster ecosystem functions is positive for the environment but may not necessarily lead into trading soil carbon.

The Macedon Ranges Shire Council’s draft Road Management Plan takes no account of increasing numbers of pedestrians on some minor rural roads and increased wildlife population on roadside verges and surrounding farm and public land. It provides no data on vehicle road maintenance diesel use and their greenhouse gas emissions trends.

Anecdotal examples of increasing soil carbon stocks by changing livestock grazing and pasture management are common, but long term statistically significant trial data demonstrates making a significant change is likely to be difficult especially in perennial pasture paddocks where the existing carbon level in above 3%

Trees age. And at some point, they die. When that happens, decay begins, sending carbon back into the atmosphere as CO2. Other smaller trees will then take over, thereby leaving a fairly stable CO2 stock in the forest.

Applying artificial climate treatments to pasture species without including different grazing regimes is absurd, it makes the research conclusions around pasture species resilience in face of climate change irrelevant.

Some native grass species will respond to increased plant available phosphorus, but best practice grazing management is critical to ensure their persistence when fertiliser is applied.

Regen Ag has emerged over the last five years under the misapprehension of providing a more holistic methodology for profitable farming while improving ecosystem functions compared to conventional or agricultural science based farming.

The challenge for agricultural science surrounding increasing or maintaining soil organic carbon level, is to provide farmers with knowledge that gives them confidence that the practice changes being recommended will achieve the desired outcomes under their individual soil type, climate, enterprise and business circumstances.

Our phase two pasture renovation program currently in place is producing pastures which are providing us with significantly improved pasture quantity and quality year round, lower ruminant greenhouse gas emissions, higher lamb meat eating quality, and outstanding biodiversity habitat, under a trend for lower spring and autumn rainfall over the last 20 years.

David Pollock contends there is an argument in some pastoral areas such as where Wooleen station is, for using dingoes as a means to reduce uncontrolled grazing pressure of kangaroos and feral goats because the station livestock carrying capacities are so low due to land degradation that the pastoral businesses cannot afford to contribute to the costs of dog control.

Pollock’s insights into the connections between ecosystem functions, pastures and grazing management, put him into a rare group of outstanding farm/station ecosystem managers, observers, and influencers in the industry.

According to 2019 Farrer Medalist, Professor Tim Reeves, agricultural sustainability successes have resulted from the combined efforts of scientists and farmers working together to identify, develop and adapt new technologies and systems to both address continuing challenges to productivity and profitability, and to also seize the new opportunities that continually arise.

Kangaroos do the most damage to the environment during extended dry periods when perennial grasses are forced to go into dormancy. Australia would probably be better off financially and environmentally if properties were fenced to protect them from kangaroos. Alan Lauder explains why.

The community won’t accept avoidable sheep deaths on boats as a cost of doing business, its members know that these unavoidable outcomes will end once the sheep live trade from Australia ends.

All mixed species perennial pasture paddocks on Moffitts Farm carry a high load of pasture dry matter which when combined with high soil organic carbon (4 – 5% soil organic carbon) means all rainfall (except in extreme rainfall events – over 50mm in 24 hours) is absorbed by the soil sponge. When enough rainfall is absorbed it takes days or weeks to move by sub-surface drainage to replenish the creek ponds (springs).
