Serious lawn enthusiasts who treat their turf like a professional sports field cannot afford to guess when it comes to soil health. This Rittenhouse probe is a vital diagnostic tool that takes the mystery out of lawn care by pulling precise 3/4" x 6" core samples for deep analysis. Instead of blindly throwing down fertilizer, you can actually see your soil composition to decide if aeration is truly necessary for root development.
