CONDITIONS FOR STACKING
If the hay is to be stacked, there are also special conditions that the experienced insist should be observed. This is not to say that alfalfa hay stacked under conditions quite different may not give fair results, and much depends on the locality and the climate. However, the result desired is palatable and nutritious hay and not such as is moldy, stack-burned or dusty. Stacking the hay directly on the ground is sure to mean a loss of some portion of it. Elevate the bottom of the stack with poles, timbers or other like material; put straw at the bottom and, preferably, build a rick rather than a round stack. Start the bottom sixteen or eighteen feet wide and build straight up instead of tapering or slanting the sides, as alfalfa hay will not shed rain or snow water. If there is much moisture and it is convenient to do so, use a layer of straw or dry hay of some kind every five or six feet. Keep the stack full in the middle, or a little higher than the sides, and well tramped all the time. When the stack has reached the desired height, top it out with slough grass, or dry timothy or prairie hay, or very green alfalfa, or protect with tarpaulins or boards; the boards may be nailed and chained together, lapped and weighted at the corners, making a very satisfactory roof. If these directions are followed, the losses will be kept at a minimum. The Kansas experiment station authorities say that in an experiment made there an application of salt to the hay when being stored seemed to decrease, if anything, rather than increase its feeding value. Lime applied in stacking is claimed to have a beneficial effect in preventing mold.
The raised bottom and layers of straw are useful accessories for the stack, shed or mow, while the barrel or other ventilating contrivances should not be overlooked in either sheds or mows.
