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).
Plants need specific types of soil to grow properly. When you have acidic soil and you need an alkaline or neutral soil, adding lime reduces the total acidity. However, you first need to know how the current level of acidity in the soil.By taking a test sample, you can find the soil's pH level.When tested, if the pH falls below 7, the soil is acidic, anything above 7 begins to become alkaline. Lime adds calcium and magnesium to the soil and counteracts the negative effects of a low pH.y taking a test sample, you can find the soil's pH level.
