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.
