Towed soil sampler MSP

This is the world’s first commercially available on-the-go sensor for soil pH—or for any soil chemical property. How it works is surprisingly simple, in fact it has only one moving part—a soil sampler shoe. Think of it like a large soil probe on its side. When the hydraulic cylinder pushes it in the ground, soil flows through. When the cylinder picks up the shoe, the soil in the shoe trough is pressed against pH electrodes. After a few seconds the shoe is lowered again to collect more soil. As it does, the new soil coming in moves the previous soil sample out the back of the shoe trough—and spray nozzles clean the pH electrodes. The shoe raises, and the process is repeated—with no action from the operator and no stopping. Approximately 10 samples per acre, thousands of samples per day—delivering affordable, accurate maps of pH variability.
