You can sow any garden peas as late as December 25, if the ground is in good condition and the temperature not too low. They are grown as a winter crop except when the ground freezes. You would not get as much good for the grove by growing these peas for the market as you would by plowing the whole growth under green, but you certainly will get advantage from the decomposition of the pea straw and of the root growth of the plant.
Grass for Green Manuring.
I wish to sow this fall some green grass to be plowed in next spring to
improve the soil of part of my land. I read for that purpose a bulletin
I had from the government, but the conditions are so different here in
California that I am very much puzzled which kind to select.
There is no grass which grows quickly enough to be worth seeding in the fall for spring plowing. It is a good deal better to use a grain, either barley or rye, for the seed is cheap, the growth quick and you can get a good deal of green stuff to plow under. Legumes are, of course, better because of their ability to absorb atmospheric nitrogen, but any plant which makes a large green growth is good, and it is better to have a heavy weight of wild vegetation than to have a light growth of an introduced legume.
Manure with a Clover Crop.
I have an old apple orchard in which I intend to sow burr clover. In order to get the clover to grow I know that I shall have to use fertilizer of some kind and this is what I want your advice about.
If you can get it, use stable manure at the time of sowing the clover seed. Stable manure alone will restore the humus and overcome the rebellious behavior of the soil. Possibly you cannot secure sufficient quantities of it. In that case a little with the burr clover seed will give the plant a good start, or use a complete fertilizer to secure the growth of a legume in the freest and quickest way.
Fenugreek as a Cover Crop.
Fenugreek has been recommended to be as a nitrogen-gathering plant, but I cannot find information as to the amount of nitrogen it gathers in its roots and tops, nor the amount of crop per acre.
Fenugreek is a good nitrogen gatherer and is desirable for green manuring wherever you can get a good growth of the plant. You can count it worth as much as peas, vetches, etc., if you can get as much growth of the plant. It is most largely used in the lemon district near Santa Paula. The best way to proceed would be to try a small area of all the nitrogen gathering plants of which you can get the seed easily, and determine by your own observation which makes the best growth under your conditions.
