Put it through the silo cutter as soon as you can get it from the field.
Do not let it cure at all, and be sure to cut and pack well. If at all
dry, use water at the time of filling, and some salt then also, if you
desire. There is no danger of firing if you put it in with good
moisture, and by short cutting and hard packing you exclude the air. If
you do not do this you will get a silo full of manure, and possibly have
a fire while it is rotting.
Soil for Alfalfa.
What kind of soil is best for alfalfa on a dairy ranch?
An ideal soil for alfalfa is a deep well drained soil into which the
roots can run deeply without danger of encountering standing water or
alkali. Still we are finding that alfalfa is very successful on soils
which are not strictly ideal, providing the moisture is supplied in such
a way that the soil shall not be waterlogged nor the water be allowed to
remain upon the surface during the hot weather, because this kills the
plant.
Handling Young Alfalfa.
I have alfalfa that is doing very well for the first year. My soil is
sandy loam with light traces of white alkali, although it does not seem
to be detrimental to the growth thus far. I am in the dairy business and
will have by winter enough manure to top-dress the field. Would it be
good policy to use the manure, or would it be more satisfactory to
top-dress with gypsum? Would it injure alfalfa to pasture lightly after
the last cutting?
Presumably your soil contains enough lime, and therefore the application
of gypsum at this time of the year would not be necessary. It may be
desirable to top-dress with gypsum near the end of the rainy season to
stimulate the growth of the plant. Gypsum, however, has no effect upon
white alkali. So far as alkali goes, gypsum merely changes black alkali
into white, thus making it less corrosive.
There would be no objection to pasturing lightly this fall. Be careful,
however, to keep off the stock while the land is wet and not to
overstock so as to injure root crowns by tramping. The manure can be
used as a top dressing during the rainy season, unless you think it
better to save it for the growth of other crops. Alfalfa is so deep
rooting where conditions are favorable that it does not require
fertilization usually on land which has been used for a long time for
grain or other shallow-rooting plants.
Alfalfa Sowing with Gypsum.
I intend sowing alfalfa this fall on land that has some very compact
hard spots. I aim to doctor these spots with gypsum at the rate of about
1000 pounds per acre and cultivate the gypsum in thoroughly two or three
weeks before sowing the alfalfa seed. Would this be all right? Is there
danger of injury to seed by coming in contact with gypsum?
Gypsum will not hurt the alfalfa seed. It is not corrosive like an
alkali. Whether it will have time enough to ameliorate the soil in the
spots in the period you mention depends upon there being moisture enough
present at the time.
