Research on soil-water flow to plant roots has basically followed microscopic and macroscopic approaches. For simplicity, many researchers have turned to the macroscopic approach to the root extraction process to represent the withdrawal of soil water by a crop root system. The macroscopic approach was followed in this study to characterize the effect of rooting densities on water extraction patterns as a function of soil-water potentials (matric, osmotic, and gravitational). A statistical evaluation of the neutron-probe gauge reliability was performed according to the manufacturer's manual. The results obtained from the period May 14 to July 15, 1988, indicate that the neutron probe was operating properly. It was concluded from this analysis that performanceevaluation is a valid technique for detecting unusual gauge problems. ... |
