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).
If your soil is alkaline, you can lower your soil's pH or make it more acidic by using several products. These include sphagnum peat, elemental sulfur, aluminum sulfate, iron sulfate, acidifying nitrogen, and organic mulches. pH of 5.5 is 10 times more acidic than a pH of 6.5. Conversely, a pH of 8.5 is 10 times more alkaline than a pH of 7.5. A soil test will determine pH. The soil pH is important because it affects the availability of nutrients in the soil.
