What is Living Soil?
Well… it is not dirt! There are more micro organisms in a spoon full of living soil than people on the planet! These micro organisms are part of the “Soil Food Web” that can feed our plants all the nutrients they need, not just N. P. K. and a few others. Our plants need many diverse nutrients to be healthy and so do we! The microbiology also protects our pants from pests! The basic practice of living soil is to copy nature. So look how it is done in the forest and you will find these basic principles:
1. The soil is always covered with organic matter, never bare.
2. The soil is not tilled.
3. No chemicals.
4. Lots of diversity!
After that there are lots of ways we can improve our soil and speed up natures process of soil progression!
Its all about the Biology!

What can you learn from seeing your soil under a microscope?
1st thing you will see is your soil aggregation.
This is Clay. Lots of little fragments, so if you imagine pushing everything together you will have a compact medium. With no air flow and water will run off instead of saturating the soil.
You will see your amount of bacteria and amount of fungi in the soil. Advanced soils have a least a 50/50 bacteria to fungi ratio. Don’t be surprised or disappointed if you see mostly bacteria in your sample… you will then have a goal to achieve more fungi!
If your soil has other microscopic life like Nematodes, Protozoa, or Arthropods. Diversity is they key for a balanced nutrient cycle to get that Soil Food Web going! But too many Arthropods or Protozoa(ciliates) is a sign that your soil is going anaerobic.
Also if you have any non Beneficial’s like Oomycete’s that can lead to problems like Powdery Mildew.
