Soil Aeration and Tree Health: Correlating Soil Oxygen Measurements With the Decline of Established Oaks

L. R. Costello, J. D. MacDonald, K. A. Jacobs, 1991

The paper studies how environmental stress on urban trees can be reduced by understanding the soil aeration required for the growth of healthy trees. As a part of the experiment methodology the researchers, measure the soil aeration status at different field locations. It measures the oxygen levels to compare the health of these trees. The results of the study show that the oxygen diffusion rate of the soil and moisture content in it are interdependent and promote healthier growth of the tree.
