Soil structure
Aggregation, compaction, and infiltration, the way roots feel it.
How the roots feel it
Structure is the thing no test ever captured well — until now. Aggregation, compaction, infiltration: the shape of the soil, which decides everything else.
What we measure
aggregates crumb size, the soil's skeleton compaction penetration, down to the hardpan infiltration how fast water actually goes in tilth the number the shovel already knew
Why it matters
You can have perfect chemistry in dead, bricked soil and grow nothing. Structure is the chassis.
