Soil Health Principles

You Can Cut Fertilizer Dramatically

Real farming uses the natural microlife in the soil, not synthetic fertilizers.

Soil ecologist Dr. Christine Jones lays out five core principles for rebuilding soil biology — and why that biology, not another bag of fertilizer, is what actually restores fertility. In short: photosynthesis feeds soil microbes through living roots, those microbes make minerals plant-available, and synthetic nitrogen and phosphorus routinely short-circuit that whole exchange while eroding the soil structure underneath it.

01

Keep Something Green, Year-Round

Photosynthetic capacity — how much living green cover you have, and how actively it's growing — is the single biggest lever for pulling carbon into the soil. Bare ground has none, and it's losing carbon the whole time it's bare.

02

Diversify What You Grow

Multi-species cover crops and mixed plantings feed a wider range of soil microbes than a monoculture ever can — and diverse stands hold up far better under drought stress.

03

Go Easy on Nitrogen

Only 10–40% of applied nitrogen fertilizer is actually taken up by the crop — the rest is lost to volatilization and leaching, and heavy N use trains plants to stop feeding their own microbial partners.

04

Go Easy on Phosphorus

Most soils already hold decades of P from past applications — it's often locked up, not absent. Activating the microbes that unlock it beats adding more.

05

Avoid Aggressive Tillage

Tillage looks like a quick fix but depletes carbon, wrecks mycorrhizal fungi and earthworms, and leaves soil more exposed to erosion.
