Hello all
I have a project in which I am evaluating the effects of adding limestone to the surface of a large area (over 100 acres) of stored river/canal dredge material. After applying the limestone, it is then disked into the soil. The objective is to determine whether adding the limestone can help to keep the pH of soil pore water (from the unsaturated zone) at a target of about 6.5.
Monitoring methods for this project include the use of suction lysimeters and monitoring wells for characterizing soil pore water and groundwater, respectively.
I am questioning the use of the lysimeters and am trying to determine if there is any benefit to measuring soil pH instead of pore water pH. Soil pH tests are cheaper and less complicated than collecting samples from lysimeters.
I am wondering if anyone has experience with lysimeters and whether it seeems reasonable to jettison them in favor of soil pH tests.
Thx for any info.
