Question

The study “Evaluation of Prescribed Burning in Relation to Available Deer Browse” was undertaken at the Virginia Polytechnic Institute and State University in 1964 to determine if fire can be used as a viable management tool to increase the amount of forage available to deer during the crucial months in late winter and spring. Calcium is a required element for plants and animals. The amount taken up and stored in the plant is closely correlated to the amount present in the soil. It was hypothesized that fire may change the calcium levels present in the soil and thus affect the amount available to the deer. A large tract of land in the Fishburn Forest was selected for a prescribed burn. Soil samples were taken from 12 plots of equal area just prior to the burn on May 20, 1964, and analyzed for calcium. On July 16, 1964, postburn calcium levels were analyzed from the same plots. These values, in kilograms per plot, are presented in the following table. Do these data support the hypothesis?
