Walnuts In Alfalfa
Will the walnut trees be injured in any way by irrigating them at the
same time and manner as the alfalfa - that is, by flooding the land
between the checks? Will the walnuts make as good a growth when planted
in the alfalfa, and the ground cultivated two or three feet around the
tree, as though the alfalfa was entirely removed? Is it advisable to
plant the trees on the checks rather than between the checks?
Walnut trees will do well, providing you do not irrigate the alfalfa
sufficiently to waterlog the trees; providing also that you do use water
enough so that the trees will not be robbed of moisture by the alfalfa.
This method of growing trees will be, of course, safer and probably more
satisfactory if your soil is deep and loamy, as it should be to get the
best results with both alfalfa and walnuts. It would be better to have
the trees stand so that the water does not come into direct contact with
the bark, although walnut trees are irrigated by surrounding them with
check levees. Planting walnut trees in an old stand of alfalfa is harder
on the tree than to start alfalfa after the trees have taken hold,
because the alfalfa roots like to hang on to their advantage. In
planting in an old field, we should plow strips, say, five feet wide and
keep it cultivated rather than to try to start the trees in pot-holes,
although with extra care they might go that way.
