For folks who like a deep dive, Grist outlines an unexpected benefit of fiber to the farm…

Fiber optic cables, of all things, have now exposed just how badly tilling messes with a farm’s ability to retain moisture. Using a technology known as distributed acoustic sensing, or DAS, scientists analyzed how seismic waves disturbed the cable as they rippled through harrowed fields compared to adjacent undisturbed plots. This created subtly distinct signals, showing that plowing obliterates the “capillaries” that carry water like tiny interconnected reservoirs.

The findings point to a serious problem with modern agriculture, to be sure, but also to solutions. “Regenerative farming practices based on principles of no-till — combined with cover crops and a diversity of crops — can basically lead to less agrochemical reliance, better soil organic matter contents, comparable yields, [and] lower diesel use,” said David Montgomery, a geomorphologist at the University of Washington and coauthor of a new paper describing the research.
