Slakes: Soil Health Test

Unlock the power of soil health assessment with the Soil Health Institute's Slakes app. Easily and accurately measure wet aggregate stability – a key indicator of soil health.

Key Features: • Open access to a reliable method for soil health assessment • A simple process for photographing three air-dried soil aggregates before and after a 10-minute water submersion • Automatic soil area estimation using an advanced pixel thresholding algorithm • Calculation of a dimensionless aggregate stability index, indicating soil health • Index values ranging from ~0.1 to 1, with higher values representing greater aggregate stability
