| Question: | "We are sending you a sample of some humus which we can buy for $7.50 a ton delivered. We are also sending you a printed circular giving its analysis. We should appreciate your advice as to the value of this material for use as top-dressing on our greens. We seem to be unable to procure any other good top-dressing material, finding that the preparation of compost is a rather irregular and uncertain proposition." |

| Answer/Response: | "The types of peat or humus of which you send us a sample are valuable chiefly for their content of organic matter and possess practically no fertilizing value, since the nitrogen, phosphorus, and potash which they contain are in a very insoluble or inactive form and could not be rendered available to the plant except under special treatment. The price of your material is therefore, in our opinion, out of proportion to its value. Good garden loam may be procured much more cheaply; and by mixing 100 pounds of sulphate of ammonia, 100 pounds of acid phosphate, and 25 pounds of muriate of potash with 4 or 5 tons of garden loam, a very good top-dressing material would be obtained, provided of course the material were comparatively free from weed seeds and of a good physical structure. Good loam could probably be obtained by you for from $2 to $3 a ton. Also strawy manure of any kind is far more valuable than peat or commercial humus. The plant food in the manure is not only more readily available, but the manure aids bacterial action in rendering soil constituents available as plant food, and also is practically 100 per cent organic matter. Peat has nevertheless a place on the golf course when good loamy soil can not be procured and when sufficient manure is not obtainable. In the construction of compost piles or soil beds, peat may largely replace manure, which is generally used. It is, however, well to use some fresh manure in the compost pile or soil bed along with the peat in order to stimulate bacterial action. Frequent cultivation of such a mixture of peat, soil, and manure renders the peat more available and develops a fair soil structure by thoroughly mixing the constituents. Often natural beds of peat can be located nearby a golf course." |
