This product is an on board nitrogen generator. Most companies purchase nitrogen in cylinders at about 2000 p.s.i. We at Pit Crew Tire Service have chosen to invest in a system that will create nitrogen on demand and store it in an on-board 80 gal storage tank at low pressure. (170 p.s.i. for safety concerns) The USA trails European tire technology by about 10 years.
The pH scale indicates acidity or alkalinity. A soil with a pH number below 7 is acid, while one with a pH above 7 is alkaline. Garden plants typically grow best in neutral or slightly acid soil (pH 7 or slightly below; see illustration at left).
You can buy your own soil pH tester, which can be found at your local garden center, or you can bring a sample of your soil to your local garden center and have them test it for you. Whether youâre an expert, or starting your first garden, this will give you a definitive starting point. Another way to tell if you need to raise soil pH, is if you have a lot of weeds or moss in your lawn. Because weeds and moss thrive at a lower pH (ie. a more acidic soil), an excess of them in your yard can be a good indication that your soil is too acidic, and soil pH needs to be raised. Still yet another sign that you need to raise your soil pH, is when fertilizer applications do not seem to be helping.
