How accurate are the home kits for soil analysis? I recently tested both my veggie bed which was a potting soil/compost/touch of peat moss mix (supplied by my landscaper...who knows what quality he got) and also my native soil where all my fruit trees are sitting in. My native soil is a total clay soil. Veggie bed came back totally nitrogen and phosphorous depleted whereas my clay soil seemed fine in everything except for of course that it's unfortunately not draining very well. Do you guys trust the home kits or send out for professional analysis?
