Peak Root is a planning aid. A pass or a fail is the result of the method described in the app, applied to the numbers you enter and to published climate normals. It is not agronomic advice, not a guarantee of yield, and not a substitute for measuring your own soil and weather.

Soil constants are class midpoints. Crop coefficients follow FAO-56 tables, and where a crop is absent from those tables the app names the stand-in it uses. Climate values that are not in the station file are marked as defaults.

The app is provided as is. You are responsible for the irrigation decisions you make from it.
