The Living Soil Cycle

How the System Works

Everything MicrobeGrower teaches follows one circle, and each step feeds the next.

Producing a lot of manure or farm waste? See Compost Services to turn it into biologically complete compost.

1. Make It

Build biologically complete thermal compost and worm castings from materials you already have on hand.

2. Check It

Look through the microscope to see whether your compost, tea, or soil holds the bacteria, fungi, protozoa, and nematodes your plants need.

3. Use It

Apply compost, extracts, and teas so the right biology reaches your soil and your plant roots.

4. Rebuild

As soil life takes over nutrient cycling, your soil needs less from you every season. Then the cycle starts again, with better compost and better soil every time.

Find Your Path

Where Do You Want to Start?

Become a Student

Learn thermal composting and vermicomposting step by step, so you can make biologically complete compost yourself.

Test Your Compost or Soil

Mail in a sample of your compost, tea, or soil and find out exactly what is living in it, with organism counts, photos, and recommendations.

Shop Living Amendments

Jumpstart your soil biology with Biological Complete Soil Starter or BioChar MicroBlend while your own compost gets going.

Everything I Teach Comes From Soil I Built Myself

Wendy Mickle, Soil Food Web School Certified Consultant, Maine

I am a Soil Food Web School Certified Consultant who trained in Dr. Elaine Ingham's methods, and on my homestead in Parsonsfield, Maine, I run thermal compost piles, a flow-through worm bin, and my own microscope work. Every course I teach and every assessment I write comes from soil and compost I have built and checked myself, so you are learning a system that has been tested in the ground, not just on paper.
