Farming sustainably and efficiently has gone from a big tractor problem to a big data problem over the last few decades, and startup EarthOptics believes the next frontier of precision agriculture lies deep in the soil. Using high-tech imaging techniques, the company claims to map the physical and chemical composition of fields faster, better, and more cheaply than traditional techniques, and has raised $10M to scale its solution.
“Most of the ways we monitor soil haven’t changed in 50 years,” EarthOptics founder and CEO Lars Dyrud told TechCrunch. “There’s been a tremendous amount of progress around precision data and using modern data methods in agriculture – but a lot of that has focused on the plants and in-season activity — there’s been comparatively little investment in soil.”
While you might think it’s obvious to look deeper into the stuff the plants are growing from, the simple fact is it’s difficult to do. Aerial and satellite imagery and IoT-infused sensors for things like moisture and nitrogen have made surface-level data for fields far richer, but past the first foot or so things get tricky.
Different parts of a field may have very different levels of physical characteristics like soil compaction, which can greatly affect crop outcomes, and chemical characteristics like dissolved nutrients and the microbiome. The best way to check these things, however, involves “putting a really expensive stick in the ground,” said Dyrud. The lab results from these samples affects the decision of which parts of a field need to (Read more...)
