You will have to make an estimate from the above data to
serve your purpose and you can figure it either by the number of animals
or by the tonnage of the feed.
Value of Fresh and Dry Manure.
What is the relative value of the weekly or semi-weekly corral scrapings
which are tramped fine and air-dried; and of the fresh, wet manure from
the stable? I do not understand that the latter has appreciable water
added, and the amount of sand in the corral scrapings would be small.
Fresh, mixed animal manure is usually calculated to contain about 75 per
cent of water. Manure which has been quickly dried, without fermentation
and without leaching by rains, may be worth four or five times as much
per ton. Nothing, however, short of analysis would determine the value
of any particular lot, for that depends somewhat upon the way the
animals are fed, as well as upon the moisture content.
Shavings in Stable Manure.
Is barnyard fertilizer containing shavings instead of straw, desirable?
Barnyard manure containing shavings is chiefly objectionable because of
the amount of inert material. The shavings are exceedingly slow to
decompose, and in light soil in considerable quantities would cause a
serious loss of moisture. If applied, on the other hand, to a heavy soil
and accompanied by sufficient irrigation water, the effect of making the
soil more friable might be very desirable.
