I just moved to a new area, and am planning to start my own garden. Not just a “hobby”, I will be depending on the success of my crops. The best think you can do is know what kind of soil you are dealing with. This company has their own lab. and are “professionals”. I collected the soil as instructed – it is an extremely simple process – and mailed it on the pre-paid envelope. In less than 2 weeks, I had my results online and printable, along with recommendations for amendments. WORTH EVERY PENNY – if you are serious about your garden. I highly recommend purchasing this soil test kit.
