Green browse plots provide attractive and nutritious forage to complement native food supplies. They may also attract an abundance of insects which are vital for turkeys and quail during the spring and summer months.
Many types of green browse plots may be established for wildlife depending on objectives. An all-purpose plot of legumes within a thin stand of grass provides green forage for turkeys, deer and rabbits, and insects for turkeys and quail. The addition of Summit, Kobe, or Korean lespedeza to the plot will provide lespedeza seed for quail, as well as green forage for other wildlife during summer periods when clovers may become dormant.
If interested primarily in deer or rabbits, plots of legumes, cereal grains, brassicas and other plants will produce much more green forage. However, such lush stands are not preferred by turkeys or quail.
Select a site which is open and tillable but adjacent to suitable cover. Stay at least 50 feet from any woodland edge to reduce competition with trees and to permit the establishment of a buffer strip of perennials and shrubs between the food plot and the timber. Plots should be placed on flat ridge tops, bottomlands, or along the contour of gentle slopes.
For deer and turkey: The plots should be placed about 1/4 mile apart, or one per 40 acres and be a minimum of one acre in size. For rabbits: The plots should be spaced one per six acres and may be as small as 1/4 acre.
Seedbeds for green browse plots are typically prepared in August thru or early October. Fertilizer should be applied and worked into the soil at the time of seedbed preparation. However, it may be beneficial to apply lime several months in advance. Correct fertilization is essential for successful establishment and long term maintenance of the plots. If possible, a soil sample from the plots should be taken to the County Extension Office for analysis of fertilizer needs. (Emphasize the purpose of the food plot and species to be planted). Extension will then provide recommendations for both initial fertilization and annual top dressings of fertilizer. In absence of soil test recommendations, the following starter application should be sufficient.
If the site has not been limed previously, apply 3–5 tons per acre.
Apply approximately 30 pounds of nitrogen (N), 90 pound of phosphorus (P) and 90 pounds of potassium (K) per acre. An application of 400 pounds per acre of 6-24-24 fertilizer will provide 24 pounds of nitrogen, 96 pounds of phosphorus and 96 pounds of potassium per acre. Care should be taken not to apply more than 40 pounds of nitrogen plant food because it will stimulate excessive growth of grasses and weeds which may crowd out the legumes.
Clip the plots each year between July 1 and 15 and top dress with 50 pounds of phosphate plant food and 50 pounds of potash plant food each September. Omit nitrogen fertilizer if possible. If you must use a fertilizer containing nitrogen, apply less than 20 pounds of nitrogen plant food per acre. Renovate and reseed when grasses or weeds have crowded out the desired legumes.
For maximum value to wildlife, plantings must be protected from excessive grazing. Light grazing that would remove about one-half of the growth during the last half of June is desirable in lieu of clipping. Do not graze during the fall or winter months.
