Measuring Soil Biology with a Pair of Skivvies
Healthy soil means hungry soil. With proper management, the ground beneath your crops should teem with millions of tiny lifeforms—bacteria, fungi, protozoa, nematodes, arthropods, earthworms—all busy transferring nutrients, eating, and decomposing organic material through nutrient cycling in processes that help plants thrive. So how do you measure the biological activity of your soil? Enter the “Soil Your Undies” test. Simply bury a pair of white, 100% cotton undies beneath your soil, come back two months later and dig them up. Sterile, lifeless soil will keep your tighty- whities clean and intact whereas busy, organically thriving soil will eat away at your briefs, leaving nothing but an elastic strap!
