| Question: | "We are offered a commercial fertilizer analyzing 15-30-15 at $90 a ton delivered. What is its value in comparison with cottonseed meal at $45.50 a ton delivered?" |

| Answer/Response: | "We compare fertilizers for turf work chiefly on the basis of the nitrogen content since this is the element which is most costly and of most value for growing fine turf. Cottonseed meal usually analyzes 6-3-2. If 6 per cent of nitrogen, such as contained in the cottonseed meal, costs $45.50 a ton, 15 per cent, as contained in the commercial fertilizer you mention, would be worth $113.75 a ton. Therefore on the nitrogen basis alone the commercial fertilizer at $90 a ton would be an economy. We do not, however, recommend a fertilizer analyzing 15-30-15 for regular use on putting greens or fairways, since it is too high in phosphorus (30 per cent) and potash (15 per cent). One or two applications of such a fertilizer to greens or fairways would probably be beneficial, but if used constantly the phosphorus and potash content of the soil might be increased to such an extent as to cause trouble from clover and weeds. Cottonseed meal, pulverized poultry manure, and activated sludge, each of which analyzes about 6-3-2, are in our opinion better balanced for fine turf purposes than the commercial fertilizer to which you have referred. These three 6-3-2 fertilizers possess further advantage in that, being organic fertilizers, they decompose more slowly and thus have a more lasting effect than the inorganic fertilizers. "\Vhere quick results are, however, desired, the inorganic fertilizers are to be preferred. Sulphate ammonia at a cost of about $60 a ton contains 20 per cent nitrogen. Detailed information on determining the value of commercial fertilizers is contained in the article on page 113 of the Bulletin for June, 1928." |
