If the manure in the heap is too dry, it is a good plan, when you are killing hogs, to throw on to the manure all the warm water, hair, blood, intestines, etc. You may think I am making too much of such a simple matter, but I have had letters from farmers who have tried this plan of managing manure, and they say that they can not keep it from freezing. One reason for this is, that they do not start the heap early enough, and do not take pains to get the manure into an active fermentation before winter sets in. Much depends on this. In starting a fire, you take pains to get a little fine, dry wood, that will burn readily, and when the fire is fairly going, put on larger sticks, and presently you have such a fire that you can burn wood, coal, stubble, sods, or anything you wish. And so it is with a manure-heap. Get the fire, or fermentation, or, more strictly speaking, putrefaction fairly started, and there will be little trouble, if the heap is large enough, and fresh material is added from time to time, of continuing the fermentation all winter.
Another point to be observed, and especially in cold weather, is to keep the sides of the heap straight, and the top level. You must expose the manure in the heap as little as possible to frost and cold winds. The rule should be to spread every wheel-barrowful of manure as soon as it is put on the heap. If left unspread on top of the heap, it will freeze; and if afterwards covered with other manure, it will require considerable heat to melt it, and thus reduce the temperature of the whole heap.
It is far less work to manage a heap of manure in this way than may be supposed from my description of the plan. The truth is, I find, in point of fact, that it is not an easy thing to manage manure in this way; and I fear not one farmer in ten will succeed the first winter he undertakes it, unless he gives it his personal attention. It is well worth trying, however, because if your heap should freeze up, it will be, at any rate, in no worse condition than if managed in the ordinary way; and if you do succeed, even in part, you will have manure in good condition for immediate use in the spring.
As I have said before, I keep a good many pigs. Now pigs, if fed on slops, void a large quantity of liquid manure, and it is not always easy to furnish straw enough to absorb it. When straw and stalks are cut into chaff, they will absorb much more liquid than when used whole. For this reason we usually cut all our straw and stalks. We also use the litter from the horse-stable for bedding the store hogs, and also sometimes, when comparatively dry, we use the refuse sheep bedding for the same purpose. Where the sheep barn is contiguous to the pig-pens, and when the sheep bedding can be thrown at once into the pig-pens or cellar, it is well to use bedding freely for the sheep and lambs, and remove it frequently, throwing it into the pig-pens. I do not want my sheep to be compelled to eat up the straw and corn-stalks too close. I want them to pick out what they like, and then throw away what they leave in the troughs for bedding. Sometimes we take out a five-bushel basketful of these direct from the troughs, for bedding young pigs, or sows and pigs in the pens, but as a rule, we use them first for bedding the sheep, and then afterwards use the sheep bedding in the fattening or store pig-pens.
“And sometimes,” remarked the Deacon, “you use a little long straw for your young pigs to sleep on, so that they can bury themselves in the straw and keep warm.”
“True,” I replied, “and it is not a bad plan, but we are not now talking about the management of pigs, but how we treat our manure, and how we manage to have it ferment all winter.”
A good deal of our pig-manure is, to borrow a phrase from the pomologists, “double-worked.” It is horse or sheep-manure, used for bedding pigs and cows. It is saturated with urine, and is much richer in nitrogenous material than ordinary manure, and consequently will ferment or putrefy much more rapidly. Usually pig-manure is considered “cold,” or sluggish, but this doubleworked pig-manure will ferment even more rapidly than sheep or horse-manure alone.
Unmixed cow-manure is heavy and cold, and when kept in a heap by itself out of doors, is almost certain to freeze up solid during the winter.
We usually wheel out our cow-dung every day, and spread on the manure heap.
