How often do we see manure lying under the eaves of an unspouted shed or barn, where one of our heavy showers will saturate it in a few minutes, and yet where it will lie for hours, and days, and weeks, until it would seem that a large proportion of its soluble matter would be washed out of it! The loss is unquestionably very great, and would be greater if it were not for the coarse nature of the material, which allows the water to pass through it rapidly and without coming in direct contact with only the outside portions of the particles of hay, straw, etc., of which the manure is largely composed. If the manure was ground up very fine, as it would be when prepared for analysis, the loss of soluble matter would be still more serious. Or, if the manure was first fermented, so that the particles of matter would be more or less decomposed and broken up fine, the rain would wash out a large amount of soluble matter, and prove much more injurious than if the manure was fresh and unfermented. “That is an argument,” said the Deacon, “against your plan of piling and fermenting manure.” “Not at all,” I replied; “it is a strong reason for not letting manure lie under the eaves of an unspouted building--especially _good_ manure, that is made from rich food. The better the manure, the more it will lose from bad management. I have never recommended any one to pile their manure where it would receive from ten to twenty times as much water as would fall on the surface of the heap.” “But you do recommend piling manure and fermenting it in the open air and keeping the top flat, so that it will catch all the rain, and I think your heaps must sometimes get pretty well soaked.” “Soaking the heap of manure,” I replied, “does not wash out any of its soluble matter, _provided_ you carry the matter no further than the point of saturation. The water may, and doubtless does, wash out the soluble matter from some portions of the manure, but if the water does not filter through the heap, but is all absorbed by the manure, there is no loss. It is when the water passes through the heap that it runs away with our soluble nitrogenous and mineral matter, and with any ready formed ammonia it may find in the manure.” How to keep cows tied up in the barn, and at the same time save all the urine, is one of the most difficult problems I have to deal with in the management of manure on my farm. The best plan I have yet tried is, to throw horse-manure, or sheep-manure, back of the cows, where it will receive and absorb the urine. The plan works well, but it is a question of labor, and the answer will depend on the arrangement of the buildings. If the horses are kept near the cows, it will be little trouble to throw the horse-litter, every day, under or back of the cows.
