As climate change continues and farming areas get hotter and drier—as expected in the Southern Great Plains and Southwest—erosion could increasingly take the form of dust storms when bone-dry fields are plowed. It’s a recurring ecological disaster that causes hardship for people who make their living from fishing, shrimping, and tourism.
He would let the cover crop grow and overwinter and then plow down the following spring for green manure. Whereas at one time she advocated organic approaches and specific practices to deal with singular issues with pests or crop fertility, she now fosters a system based on ecological farm design.
Your book talks a lot about “road ecology.” Ben Goldfarb: Road ecology is the field of scientific study that looks at how roads and other transportation infrastructure affect nature and what we do about those impacts. A lot of road ecology is about why roadkill happens and what its effects on populations are and how to prevent it.
She currently uses a tractor with an automatic steering system that improves planting and plowing efficiency and requires much less work, which she credits as one of the pivotal reasons shes able to successfully manage her hundreds of acres of fields on her own. Photography via Shutterstock.

Industrial agricultural practices such as tillage (plowing) and leaving fields bare between growing seasons degrade soil structure, reduce water infiltration, lower water storage capacity, and increase runoff (the flow of water across the soil’s surface).
year after year, usually with a non-cover fallow, intensive moldboard plowing, and the additions of synthetic nitrogen fertilizer. Until then, it seems to me a comprehensive, ecological approach is what’s needed. For this, we need the courage and imagination to live within our limits, just like ecology has been trying to teach us.
But European settlers were remarkably effective at shooting and poisoning prairie dogs and plowing up their burrows. Across years, enhanced forage quality may help to offset reductions in forage quantity for agricultural producers, a study published in 2019 by Rangeland Ecology and Management reported.
The plowing of agricultural land during the 19th and 20th century released vast stores of carbon dioxide , only a small part of which has since been returned to the soil. Side by side with that loss of diversity was a long growth in greenhouse gas emissions that has only recently begun to be addressed.
I also argued that non-farmers should pay more attention if they want to counter the long-time dominance of Big Agriculture in decisions shaping which basic commodities get produced, how, how much, by who, and with what long-term ecological and societal impacts. Most readers of this blog know about the Farm Bill (its generic label).
