Figure 4 Standing biomass of tall fescue on a Southwest Virginia mine soil experiment over time (Haering et al., 1990). Note that the second year yields were highest for all rock types and then declined with time. This is typical of fertilized mine soil systems, particularly when a vigorous legume component is not successfully established. Also note the pronounced effect of rock type on yield, especially in the early years.
