Loam
The gold standard — a balanced blend of sand, silt and clay.
- Strengths
- Holds water and nutrients while still draining well. Easy to work and naturally fertile.
- Weaknesses
- Rare in nature and easily degraded by tillage, compaction and loss of organic matter.
- Biology upgrade
- Biology maintains loam's crumb structure — fungi and worm castings keep it from collapsing into hardpan.
