METHOD FOR ANALYZING SULFURIC ACID ION CONCENTRATION IN SOIL

摘要

PURPOSE: To obtain a sulfuric acid analysis method which can analyze sulfuric acid concentration in soil at a field simply and readily. ;CONSTITUTION: A chart which shows a relationship between sulfuric acid ion concentration and conductivity in a soil extraction water is prepared previously. The conductivity of the extraction water is measured by sampling the extraction water of the soil whose analysis is desired, thus obtaining sulfuric acid ion concentration corresponding to the conductivity from the chart.;COPYRIGHT: (C)1993,JPO&Japio
