Abstract
A laboratory robot has been used to assess the performance of a commer cially available flow-through junction pH electrode. The electrode was tested for accuracy and precision in the determination of soil-water pH (pH(w)) and the Shoemaker, McLean, and Pratt buffer solution pH (pH (SMP)). The significance of the pH(SMP) determination lies in subseque nt calculations of soil lime requirement(LR). Response times and hyste resis effects were compared under different operating conditions.
