From the campaign «It’s time to #SoilYourUndies… in the name of soil conservation», of the SOIL CONSERVATION COUNCIL OF CANADA.
The Soil conservation council of Canada started a campaign in order anyone can investigate biological activity in farm fields or backyard gardens:
Bury a pair of 100 per cent white cotton underwear in topsoil for about two months and then check the level of decomposition. If there’s not much left of the underwear you have good biological activity, which indicates healthy soil. These same soil organisms can break down plant materials in much the same way.
WHAT YOU’LL NEED
• New pair of white 100% cotton briefs (no dyes or polyester blends)
• Marker flag
