Blue color development revealing soil phosphorus, and a $60 colorimeter, in the low-cost soil test. Left vial shows the color of a soil extract for phosphorus before reacting it with an added reagent package designed to test for phosphorus; right vial is after reagent addition.
Stable soil aggregates from the aggregate stability test, on one prototype of a low-cost soil sieve for testing the relation between soil biological and physical properties.
