One Thousand Questions in California Agriculture Answered
Wickson, Edward J. (Edward James)
Agriculture -- California
You have done unwisely in burning the manure. We would have taken the
risk of a single use of shavings for the sake of the manurial matter
associated with them, and this risk of too much lightening of a gravelly
soil would be especially small in connection with deep rooting plants
like ornamental trees and shrubbery. You have left merely the skeleton
of the manure, and much of that of doubtful solubility, if the
temperature ran very high by burning in a mass. You need not be fearful
about using these ashes. Scatter or spread them over the ground just as
you would have spread the manure, let the rains dissolve and carry down
what they can and go on with your usual methods of cultivation.
The Best Fertilizer for Sand.
How can I best fertilize soil that is pure sand?
The best fertilizer for pure sand is well-rotted stable manure, because
it not only supplies all kinds of plant food, but increases the humus in
the soil, which is exceedingly important in making the sand more
retentive of moisture as well as more productive.
Fertilizers in Tree Holes.
Would it be harmful to add 2 or 3 pounds of steamed bone meal to the
hole of a young tree just before planting?
There would be no injury, providing you mix it with a considerable
amount of soil by digging over the bottom of the hole, but our
conviction is that on lands which are good enough for the commercial
planting of fruit trees, it is not necessary to stimulate a young tree
in this way, but that it is better to postpone the use of fertilizers
until the trees come into bearing and show the desirability of more
liberal feeding. Of course, if young trees do not make satisfactory
growth, they may be stimulated either with some kind of a fertilizer or
with a freer use of water, and it is generally the latter that they are
chiefly in need of.
Wood Ashes and Tomatoes.
Is there any harm to vegetable growing to dig sufficient of wood ashes
in for mellowing heavy soil? My tomato plants grew splendidly this year,
but the fruits were all rough and wrinkled. I gave them plenty of horse
and poultry manure at planting and plenty of wood ashes and falling
leaves of cypress later.
Wood ashes do not mellow a heavy soil. The effect of the potash is to
overcome the granular structure and increase compactness. Coal ashes,
because they are coarser in particles and devoid of potash, do promote
mellowness, and are valuable mechanically on a heavy soil although they
do not contain appreciable amounts of plant food. You are overfeeding
your tomato plants, probably. The chances are that you had poor seed.
There is no best tomato, because you ought to grow early and late kinds:
there is also some difference in the behavior of varieties in different
places.
Was It the Potash or the Water?
