METHOD FOR DIAGNOSING ACID BUFFERING CAPACITY OF FOREST SOIL AND ACID RAIN USEFUL LIFE, AND METHOD FOR DISTRIBUTING AND ANALYZING DIAGNOSTIC RESULT IN REGION

Japanese Patent JP3715589

B2

PROBLEM TO BE SOLVED: To provide a method for diagnosing a general acid buffering capacity of a forest foil and to provide a method for diagnosing an acid rain useful life of the forest soil and a method for effectively reducing the collecting number of analyzing a soil sample in these methods.
SOLUTION: The method for diagnosing the general acid buffering capacity of the forest soil according to a total value (Σ) of measured values after the forest soil is sorted according to each constituting factor and the acid buffering capacity of each constituting factor is measured under optimum conditions is obtained. The method for calculating the acid rain useful life (Y) of the forest soil according to a calculation formula of "Y=(Σ×30)/R" from the total value (Σ) and a proton amount (R) in an annual rainfall amount is obtained. The method for grasping the general acid buffering capacity or the acid fail useful life annual amount of object region by an analysis of the soil sample by deciding the collecting point and the sample amount of the necessary and soil sample without waste from a γ-ray dose distribution diagram of the object region is obtained.
