Question:"We are sending you three pieces of sod from three different greens on our course. During the past season each of these greens suffered several attacks of what appeared to be brown-patch. These greens have not received any lime. Several other greens on our course were treated with lime in April, and they have suffered less from brown-patch. We should be glad to have your advice as to whether or not these greens could be expected to improve with applications of lime. We are using a 7-9-2 fertilizer on our greens in spring and fall. Is this a well balanced fertilizer?"
Source of Question:Missouri
Answer/Response:"We have tested the soil of the samples of sod which you have sent us and find the soil in all three of the samples to be neutral in reaction, all testing around pH 7. With this condition we should not expect that lime would be of any particular benefit to these particular greens. The soil of your No. 1 and No. 2 greens is a clay loam, and we find that the soil immediately below the turf is packed or puddled. This condition has greatly restricted the root development of the grass, the turf lying on top of the hard clay like a thin blanket. The seperation is further accentuated by a thin layer of peat which lies just below the turf. The condition of your No. 3 green is similar except that the surface soil is a silt and not a clay. We feel that the correct treatment for these greens is to remove the sod, put on a layer of coarse sand, then a layer of well rotted manure or other organic material, then plow these into the soil, and follow with a thorough disking. This treatment would give you a bed of good, friable soil to a depth of 6 or 8 inches. The mixing of sand and manure into the soil would put it in good physical condition. The area could then be rolled and hand-raked and the sod replaced. While this work is being done such tile drainage as might be found necessary should be installed. The 7-9-2 fertilizer which you are using is what would be called a complete fertilizer in general agricultural practices. For turf growing purposes however a fertilizer higher in nitrogen than either phosphorus or potash is to be preferred. The use of complete fertilizer on putting greens in early spring and fall is desirable, but during late spring and summer we advise the use of fertilizers of high nitrogen content and containing little or no phosphorus or potash."
