New path to monitor soil carbon

An eye in the sky and machine-learning methods could be as accurate as old-fashioned soil testing

By
Just how much carbon is in the soil? That’s a tough question to answer at large spatial scales, but understanding soil organic carbon at regional, national or global scales could help scientists predict overall soil health, crop productivity and even worldwide carbon cycles. Classically, researchers collect soil samples in the field and haul them back

Tech firm aims to boost regenerative ag through A.I., machine learning

Terramera proposes to cut emissions, sequester carbon through efficiencies

By ,
A Vancouver ag tech firm is pitching a proposal to both public- and private-sector investors that would use Microsoft technology to help the ag sector “pull carbon from the air.” Terramera on Monday put forward a $730 million proposal for an initiative it calls the Global Centre for Regenerative Agriculture, which would oversee efforts to

Canadian farmers have made significant emissions reductions

But their contributions are little understood or recognized, a new report says

By
Canadian farmers receive too little credit for their progress in curbing carbon emissions that cause climate change, according to a new study. The Canadian Agri-Food Policy Institute (CAPI) recently released the report, which took full aim at another recent report from the Intergovernmental Panel on Climate Change. CAPI says it fails to mention “the Canadian

Study shows grassland environmental contributions

The University of Alberta in partnership with Alberta Environment and Parks has undertaken 
a number of studies looking at the impacts of land use and grazing on soil carbon levels

By
Grasslands punch above their weight when it comes to carbon sequestration. That’s the conclusion of a researcher who started his career on an Alberta-wide study of how land use affects that province’s carbon pool. Daniel Hewins, now an assistant professor at Rhode Island College in Providence, R.I., says grasslands can and do store an enormous

OMAFRA seen needing a soil health ‘tuneup’

By ,
Ontario’s environmental commissioner is calling on the provincial ag ministry to rebuild its soil health expertise and find ways to encourage farmers to adopt soil-friendly production practices, to deal with what she calls a “catastrophic” loss in soil organic matter levels. The report recommends better soil carbon level monitoring and 10-year programs to financially encourage

Human security at risk as depletion of soil accelerates, scientists warn

Change is needed so that valuable, non-renewable fertilizers are recycled

By ,
Steadily and alarmingly, humans have been depleting Earth’s soil resources faster than the nutrients can be replenished. If this trajectory does not change, soil erosion, combined with the effects of climate change, will present a huge risk to global food security over the next century, warns a review paper authored by some of the top

Researchers Peg GHG Value Of Wetlands

Farmers who switch to zero tillage may brag about sequestering climate-altering carbon in their soil. But if they also drain a few swamps on their land, they’re just spewing hot air – or rather, greenhouse gases. That’s called “leakage” in the carbon credit market: the taking on of one agricultural practice to offset greenhouse gas

Organic Farming May Help Meet Climate Goals

The conversion of all U. K. farmland to organic farming would achieve the equivalent carbon savings to taking nearly one million cars off the road, the Soil Association said Nov. 26. Britain’s largest organic certification body, issuing results of a research project, said on average organic farming produces 28 per cent higher levels of soil

Grazing changes may improve climate

By
Simple changes in grazing practices could soak up millions of tonnes of carbon a year, helping fight climate change, improving farm productivity and earning farmers carbon credits, a scientist said Jan. 20. But such measures needed to spread globally to more than 120 million farmers working grazing lands, such as savannah and shrubland, according to
