The Use of History Plots in the Nursery

Each mechanical inventory involves up to 32 long plot counts per nine 400-foot beds. The development of statistical inference reduced the necessary number of counts to 0.1 percent for the spring inventory and 1.0 percent for the fall inventory. The plots are selected at random, with an average of 20 counts per nine 400-foot beds. Now, with the establishment of history plots and controlled mechanical planting, only one to three counts are necessary per nine 400-foot beds.
