The clearing out of the corridor behind #4 green will provide us with much better air flow to the green. Gas exchange in the soil is extremely important for a greens survival under stressful conditions. While plants utilize carbon dioxide and release oxygen in the leaf tissue, the process in the root zone soil is just the opposite. If a green doesn't receive air flow, the pour space in the soil is too often inhabited by water and there is no room for oxygen. Basically if a grass plants roots cant breathe then you have an unhealthy plant. Better air flow is especially helpful when we are able to open an area that is facing west from which the prevailing winds are derived. There will be a noticeable difference in the performance of #4 green this season.
