80 acres Corn seeded on 30-inch rows
One 15 inch slice on each side of GPS coordinate.
4 GPS point, 120 inch of soil slices all right angle to farmers seeing practice
Each pail will have 2 to 3 gallons of soil in them. They are hand mixed and then each pail is mixed to the same procedure that a grain sample would be mixed to create one unison sample to represent his harvest. Place that into a bag that represents a static representation of all particles that make up the A horizon of his soil. Each particle of sand, silt, clay, organic matter, fertilizer, past application and present
In order to do this with a soil probe is impossible. I have tested thousands of fields with a probe and once compacted into a pellet in the probe it hard to see what’s A and what’s B horizon let alone all the cross-contamination and never knowing what you’re really getting.
To take 120 soil probes all in one line to one depth and have the knowledge of what each particle your gathering looks like, impossible and yet we can extract samples as fast as any probe.
If your soil was a horse and it was sick and you needed a horse doctor, what kind of horse doctor would you want?
