With the only two negative points considered, the more important conditions upon which success will depend may be discussed. One chief essential is the advance preparation. Many of the most successful growers begin their preparations two or three years before they sow the seed. There must be, by rights, the most perfect physical condition of the soil. It should have been plowed deep for at least two years, and in most fields in the central and northern states a two- or three-inch subsoiling along with a seven- or eight-inch plowing will be very helpful.
If corn is to precede a spring sowing, the ground should have a liberal dressing of stable manure plowed under for humus, to encourage earthworms and to introduce the particular bacteria so essential to alfalfa’s welfare or at least furnish favorable conditions for bacteria, and the harrow should follow the plow each day. The soil’s condition should be like that for a garden. Care should be taken never to work with the ground when too wet, as such working almost inevitably results in clods and baked soil. The corn should be cultivated often, and a liberal sowing of cowpeas just before the last cultivation, which should be shallow, has been found quite helpful. This crop will repress and take the place of weeds, furnish a rich food for fattening pigs or lambs after the corn is cut, add fertility to the soil, and also introduce bacteria similar to the bacteria for the alfalfa. The cowpea, being a legume, prepares the way for alfalfa, its near relative.
