In the Edible Learning Lab, students test pH, NPK, moisture, and even the soil biota. But the soil profile includes much more. There are micronutrients, heavy metals, pesticide residues, and unknown compounds that a professional soil testing lab can measure and quantify.
Send a soil sample out to a professional lab for testing. Ask for testing that includes more than just NPK. Review the results and devise a plan to amend the soil with as many local and natural inputs as possible to remedy any deficiencies.
