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).
Soil pH is a measure of a soil alkalinity or acidity. A soil is acidic, or sour, if it has a pH below 7.0 (neutral). You may need to add lime to your soil if a soil test indicates a pH level below the optimum of 6.0 or 7.0.Soils can be naturally acidic but can also be acidified over time by natural leaching, the use of some nitrogen fertilizers, excessive rainfall or irrigation, and acidic water sources. soil is acidic, or sour, if it has a pH below 7.0 (neutral). You may need to add lime to your soil if a soil test indicates a pH level below the optimum of 6.0 or 7.0.
