Our approach
We start with the soil, not the spray schedule
Healthy ground grows crops that resist pests and hold yield through dry spells. Every Tilth plan begins with a baseline soil test and builds organic matter year on year, so certification becomes the result of good farming rather than a box to tick.

MONTH 0
Baseline

MONTHS 1–12
Transition
Cover crops, rotation changes and approved inputs only. Record-keeping starts on day one.
MONTHS 12–36
Build
Fertility builds, yields settle. Crops can be sold as transitional but not yet labelled organic.
MONTH 36+
Certified
After inspection, harvests can carry the USDA Organic seal.
The ruleUSDA organic land must be free of prohibited substances for 36 months before the crop is harvested.
