One Thousand Questions in California Agriculture Answered
Wickson, Edward J. (Edward James)
Agriculture -- California
It should be pulverized so that there shall not be lumps and masses in
the same place for fear of root injury. Of course, the strength depends
upon how much earth is gathered up with the manure. Sometimes there is
so much waste material that it can be handled just as ordinary farm
manure is.
We should not use over 20 pounds of clean droppings to a young tree and
should mix it with the soil for a considerable distance around the tree.
Old bearing trees might stand two or three tons to the acre if
distributed all over the ground. The material contains everything that
is necessary for the growth of the tree and formation of the fruit.
Ashes and Poultry Manure.
It is said that ashes mixed with chicken manure is not good. I use ashes
altogether on the drop boards because I can keep the boards cleaner. The
refuse is then scattered around the fruit trees.
Wood ashes and lime should never be used as you propose, because they
set free the nitrogen compounds which are the most valuable content of
poultry manures. This action is conditioned largely upon the presence of
moisture, and if the droppings are kept dry and hurried into the soil
the loss is lessened. Coal ashes, on the other hand, are a thoroughly
good absorbent when the coal burns to a fine ash or is sifted. They do
not act as wood ashes do, because they do not contain soluble alkali.
They also have a good mellowing effect on heavy soil.
Caustic Lime Not a Good Absorbent.
Would air-slackened lime be suitable to sprinkle over the dropping
boards in hen houses?
Gypsum is greatly superior to air-slacked lime for the hen houses, as it
has every beneficial effect of the latter, while the air-slacked lime
will set free much of the fertilizing value of the manure, which the
gypsum will not do.
Too Much Chicken Manure for Young Trees.
I have peach trees and apple trees, 3 to 6 years old, that are very
thrifty but grow only wood. The soil was poor when planting, and I have
put on plenty of sweepings from the chicken-yards. I suppose that is the
cause of the trouble.
