It depends then upon
circumstances whether shavings can be concited by Prof. Snyder in his
"Soils and Fertilizers," cows fed on hay straw is more valuable not only
because more easily decomposed, but because its content of plant food is
greater.
Handling Grape Pomace.
In the case of grape pomace, would not the large value shown by analysis
be chiefly in the seeds? My observation is that these are exceedingly
slow to became available in the soil. Would composting break down the
shell of the seed?
Grape pomace is slowly available because of the slow disintegration you
mention. It could be hastened by drying and grinding, but we doubt if
this or other treatment would return its cost. Decay by moisture
promoted by composting with manure, kept at a low temperature by
continuous moisture would render it sooner available, but this would
involve labor which, at our wage rates, would probably make the material
cost more than it is worth. This is probably a cost in which time is
cheaper than money.
Sheep and Goat Manure.
I can buy goat manure from an inclosure where this is deposited to an
amount of about five carloads. Will goat manure be of great value in
fertilizing an orchard? If so, how much of it should be spread an an
acre?
Accumulations of sheep and goat manure in a dry situation, that is,
where not leached out by heavy rainfall, have been found to run as high
as $13 per ton in fertilizing constituents.
