Great Kit Test

Purchased this kit for a middle school garden research project. With basic safety training and the printed directions from the kit, 12-year-olds were able to generate a spreadsheet for the macronutrients and pH in our raised beds, a turf research area, and a small, high density orchard. The soil book and test interpretation materials with the kit are very clear and provide all information needed to compare crop needs to test results. Would like a means of replenishing the kit instead of purchasing a new one.
