The equation represents the Performance Index (PI) related to the draft of an agricultural implement, such as a plough. Here: PI: Performance Index of draft. dAIP: Change in AIP (Aerodynamic Implementation Pressure) during draftmeasurement. D: Depth of draft measurement. The Performance Index of draft provides insight into the draft efficiency of an agricultural implement. It's a measure of how effectively the implement can penetrate the soil and perform its task with minimal resistance.
