Understanding Soil
This excerpt covers:
What color is soil?
What do different colors of soil indicate?
What does soil smell indicate?
How can you test soil drainage?
Indicators of aerobic/anaerobic soil activity
Soil texture, including:
- particle size
- Loamy, good texture forms a ball but remains crumbly, feels slippery, like talcum powder (silt also feels slippery)
- Sandy soil, when you add water, the ball falls apart and your hands get dirty, and feels gritty
- Clay soil, when you add water and form a ball, it sticks together - even when thrown against a wall (editorial note - choose your wall carefully) and feels sticky - Most soils are a mixture of sand, silt, and clay
- Most earth has layers of various types of soil
Biological activity tests:
Dig a hole, 1x1.5 feet and count your earthworms. You should have 6-10 during growing season (temperate)
Examine how long it takes biological material to decompose. Faster means more active and diverse microbial activity
