Better Aggregates, Better Soil: Farmers Dig Into Aggregates for Soil Health
Soil aggregates are the backbone of the soil’s ability to grow plants and support life. They’re small clumps of soil that are held together by the compounds released when organic matter from plants and manure is decomposed and transformed by soil microbes.
Three farmers—Lee Tesdell, Dave Struthers, and Paul Lengeling—share their perspective on how aggregate stability has correlated with improvements on their farms. Plus, we’ll show you how to measure aggregate stability using a slake test. Check it out!
