The larger labs will have a box you can check for per acre or per 1000 sq ft. Unless your garden is huge, the 1000 sq ft can really help you math wise. I agree with brownrexx that its important to find a lab that you can understand. The lab i use has a graph feature and will do recommendations of how much you need to apply for optimum results. The test i order is a complete lab work up with npk, ph, om, macro, and micros. Cec, enc, on and on. I grow giant watermelons as a hobby so i like to tune into all the nutrients.
