On the other hand the large amount of water in the manure of the cow and the pig produces a dense, heavy, cold manure that does not heat and in a large mass does not undergo rapid decay. These characteristics will be referred to in discussing the preservation of manure. VALUE OF MANURE The annual value of the manure of different farm animals per thousand pounds of live weight and per ton is given in table 3. In every case, at the scheduled price of the organic matter and the plant nutrients, the urine is more valuable per ton than the dung. The value per ton of both urine and dung increases regularly with the proportion of dry matter. When all the urine and dung are saved together, the value of the mixed material per ton ranges from $2.30 for the pig to $5.65 for the sheep and $7.25 for the hen. The manure of all these animals, especially of the horse, the sheep, and the hen, is generally handled in a drier form than when freshly voided, that of the sheep and the hen frequently in the air-dried form. Such material has a correspondingly higher value in proportion to the water removed, and poultry FlG. 13. WASTEFUL STORAGE OF MANURE The result of such practice is shown in figure 14 and sheep manure may be worth as much as fourteen dollars per ton at the schedule of prices used. The annual value of the manure of animals per thousand pounds of live weight ranges from twelve to fifteen dollars for the urine and from twenty to twenty-three dollars for the dung, that is, the value of the dung is about twice as much as that of the urine. The total annual value of both urine and dung produced by a thousand pounds of live weight is surprisingly uniform and averages about thirty-six dollars at the prices use...
