| Question: | "Does cottonseed meal introduce clover on soils where legumes occur naturally?" |
|---|
| Source of Question: | Colorado |
|---|
| Answer/Response: | "Cottonseed meal in itself would not introduce clover, but if clover seed gets into a green through top-dressing or by natural distribution the 3 per cent of phoshoric[phosphoric] acid and 2 per cent of potash contained in the meal would favor the development of the clover. At the same time some phosphoric acid and some potash are necessary for the best development of grass, especially on soils which may be deficient in one or both of these fertilizing constituents. The compost with which putting greens are fertilized usually takes care of this need, but occasionally on some soils a deficiency of phosphoric acid or potash is shown by the quick and vigorous growth of grass after one or both of these fertilizing elements are supplied. An excess of either phosphoric acid or potash would stimulate the growth of clover and various weeds, but with an occasional application of cottonseed meal, which is relatively low in these elements and high in nitrogen, clover is not stimulated at the expense of the grass. Apparently the best means of supplying a little phosphoric acid and potash to the turf each year is the use of the organic form of fertilizer, since organic matter is beneficial to soils, helping to conserve soil moisture and open up and otherwise improve the physical condition of the soil. Cottonseed meal is rather high in price at present, but other organic fertilizers, such as activated sludge, soy bean meal, pulverized poulty manure, and castor bean pomace, which are relatively low in phosphoric acid and potash, may be used in its place. Once greens are well weeded the turf should receive what it requires, and in the spring and fall growing seasons a little phosphoric acid and potash are safe to use. The supply of nitrogen should, however, be kept up, as it will stimulate the grass; but apparently clover does not require much artificial nitrogen, since due to its peculiar root system it is able to make use of the nitrogen which is taken from the air by certain bacteria which inhabit its roots. Usually some weeds and clover are introduced into a green through top-dressing, but if the nitrogen content is kept high in fertilizers there need be no fear of stimulating these beyond a good development of the grass." |
