| Question: | "I have read a good many articles during the last six months, some of them prepared by men of national repute in their line, on the dangers of applying fertilizers with high nitrogenous content in the hot summer months, basing their advice not on opinion but on fact. One would be apt to gather from these articles that fertilizers high in nitrogenous content would, under such conditions, do more harm than good. I recognize, of course, that such fertilizers have to be used with extreme care; but at the same time I am unable to see how, if you apply no nitrogen through the summer months, you can make up for the loss incurred by grass due to constant close cutting. It would seem that theoretically the ideal fertilizing plan would be to bring one's greens to perfection in the late spring, with the grass not forced but strong and vigorous, and then to hold that balance, varying treatments with weather conditions. Such a plan would call for replacing in exact amount the various chemicals lost. In such a case nitrogen would certainly be required. If such a plan is theoretically sound it would seem to be not a matter of withholding nitrogen for fear of injury to the grass, but of learning the correct amount to be applied and correct method of application. Condemning its use because of its constant misuse is not the best method of encouraging cautious experiments. If my understanding in this matter is not sound I should appreciate your advice." |

| Answer/Response: | "Reports have recently appeared from many reputable turf experts warning against the overfeeding of turf with nitrogen during the hot months. We are in accord with this advice, since there is ample reason to suspect that a soft, lush grass is not hardy enough in hot weather to withstand various fungous diseases or physiological changes to which the plant is subjected. Often there is sufficient nitrogen being released by soil micro-organisms from material already in the soil to attend to the needs of turf grasses during the hottest months of the summer. Most soils on putting greens would be fertile enough to support the grass during hot weather without other than very light feeding with nitrogenous fertilizers. The grass grows rather slowly in such seasons and does not require much plant food. Furthermore it is better to have the turf go on color a little than to have it a luxuriant green and hence liable to infections or injury common to turf in humid hot weather. We are in perfect accord with you that theoretically the ideal fertilizing plan would be to have the greens in perfect condition in the late spring, with the grass of normal vigor. The fertilizing of the grass should be reduced in the late spring. This is what horticulturists call hardening off. It would not be advisable to have a fast-growing, soft grass enter the hot summer. You are perfectly correct in doubting that fertilizers high in nitrogen are particularly dangerous. If greenkeepers would study the needs of the grass, correct amounts could be used according to requirements; and if soft growth were not forced during hot weather we think there would be less trouble with turf." |
