WebJan 1, 2002 · Root growth decreases linearly with increasing penetration resistance, until practically stopping above 300 psi. Remember, however, that roots may still penetrate soil with a penetration resistance greater than 300 psi if natural cracks and pores are present. How to use the Penetrometer WebThe atmospheric pressure is all we need. Again, the unit for gauge pressure is PSIG, and for absolute pressure is PSIA. You convert between them by adding or subtracting atmospheric pressure. 1 PSIG = 1 PSIA - atm. and conversely: 1 PSIA = 1 PSIG + atm. At sea level, the pressure of the atmosphere is 14.7. While you may not be operating at sea ...
