What we don’t know
187 of the numbers behind these plans are ones this project does not stand behind. Here they are.
Every measurement in the corpus carries a confidence tier. Most are recorded from a land-grant extension publication and checked. These are not: they are either estimated — a plausible figure nobody has confirmed against a source — or contested, where the sources disagree with each other. The planner still uses them, because a garden plan needs a number and refusing to plan is not more honest than planning with a stated estimate. What it will not do is let you believe they are measurements.
This list is generated from the corpus itself, so it cannot go stale: a number leaves this page the day it is verified, and a new estimate appears the day it is recorded.
Contested · 4
The sources disagree. Where a plan depends on one of these, the app says so at the point it matters rather than here.
- Common Bean nitrogen reaching neighbours the same season
- Corn smallest block that pollinates
- Tomato night temperature it stops setting fruit
- White Clover nitrogen reaching neighbours the same season
