The research found that “a large-scale dietary shift towards potatoes, combined with better growing methods, could reduce the greenhouse gas emissions of these staples by up to 25%”.
Indeed, Carbon Brief4 reported in August 2021 that a new study published in Nature Food demonstrated that a dietary shift from rice to potatoes in China, could “notably reduce” the climate and environmental impacts of staple crop agriculture.
Potatoes were shown to have the lowest levels of greenhouse gas emissions when compared to both pasta and rice. Potatoes were also shown to have significantly lower levels of overall water usage than rice.
Quinninup grower Glen Ryan is passionate about potatoes and is concentrating on setting up the soil and soil biology for the upcoming crop.
He will be implementing a range of regenerative practises to reduce use of fertilisers including adding specific biological inputs at certain stages. Cultivating at designated points during the potato plant growth also aids in stimulating microbes, reducing weeds, increasing drainage around the tubers and incorporating any top up fertilisers.
Stronger, healthier plants can ward off disease and pest incursions much more easily. A well developed and extensive root system aids in this, as well as increases its ability to source nutrients and water.
