Soil testers help to determine whether your soil has the right nutritional balance for plant growth, or whether you need to take steps to treat your soil. By soiling testing, you’ll know whether your the soil is too alkaline (basic, or PH), too acidic, or in the neutral zone where plants grow best. Some soil testing kits also include systems that will indicate whether there is enough calcium and other minerals for even better growth results. Zoro sells soil testing kits that include all of the chemicals, labware, probes and reference materials needed for full scale testing, as well as simple soil PH test kits. Kits vary by inclusions.
