Zero-emission cows? This might seem impossible if it weren’t for an Australian farmer who just sold 700 head of climate-neutral cattle. This turns out to be not such a difficult task.
Emission-free cattle breeding
How many times have you heard and read that cattle breeding has a negative impact on the climate by emitting significant amounts of greenhouse gases (mainly methane due to intestinal fermentation)? Meanwhile, one Australian put the lie to this claim and organized a net zero greenhouse gas cattle auction.
The Guardian reports on the unusual auction. Australian farmer Robert MacKenzie sold seven hundred Angus cows and heifers from a farm run in the so-called system at the auction he organized last Thursday. carbon neutral agriculture.
Unfortunately, MacKenzie did not find a way to convince his cows not to undergo enteric fermentation, but he achieved their “emission-free” status in another way. In theory, each of the cows did not emit a single kilogram of net greenhouse gases from the day they were born until they were sold, because the Australian’s farm absorbed more carbon dioxide than the cows emitted.
MacKenzie, using carbon farming, sequestered enough carbon dioxide in the soil on his farm to offset emissions from cattle farming. Simple, right? How beautiful the name “emission-free cows” sounds!
Carbon farming on the MacKenzie farm
In Australia, carbon farming, carbon sequestration and carbon credit projects are already quite widespread, and attempts to implement them have been progressing for years. It is worth noting that the Australian meat production sector has set a 2030 target for net zero greenhouse gas emissions.
In 2022, Robert MacKenzie tested the soil for organic carbon content on his Macka’s Pastrol farm with an area of 6,500 ha to obtain “baseline” results.
The farmer then implemented carbon farming practices designed to promote carbon sequestration in the soil: intensive rotational grazing of pastures, seeding a variety of grass mixtures, and organic fertilization aimed at improving soil health.
Already in 2023, soil tests have shown an increase in soil carbon content by 40%. and carbon dioxide sequestration of 540 kg of CO2/ha.
Soil sequestration neutralized not only emissions from cattle, but also from fuel and electricity consumption on the farmer’s farm.
