giving an average yield of about 20 bushels per acre. Some sugar 
beets are planted, producing from 10 to 15 tons per acre of beets of 
good quality. In southern Wisconsin the binder type of tobacco 
i.* grown on this phase, giving yields of 1,000 to 1,500 pounds per 
acre. Potatoes are grown chiefly for home use. 
It is a common practice on the deep phase of the Miami silt loam 
to use a rotation consisting of corn, followed by a small grain, either 
oats, barley, or wheat, then seeding to timothy and clover. The 
small grain is sown either one or two years. Hay is usually cut for 
one or two years, and the land is sometimes pastured for an addi- 
tional year. The field is then manured and again plowed for corn. 
General farming, consisting mainly of the production of hay and 
grain, and dairying are the dominant types of agriculture practiced 
on this phase. Where local market facilities are good the growing of 
special crops, such as sugar beets, peas, beans, and tobacco, is prac- 
ticed in conjunction with the production of the more common farm 
crops. 
The farms on the deep phase of the Miami silt loam are commonly 
well equipped with buildings, work stock, and machinery, and indi- 
cate a generally prosperous condition. While farming conditions 
are fairly good, the average yields produced upon this phase are 
somewhat below the natural capacity of such a soil. The rather 
general lack of organic matter in the surface soil should be cor- 
rected by the use of stable manure and the plowing under of green 
manuring crops. The use of ground limestone at the rate of 1 ton 
or more per acre would assist in securing a better stand of clover, 
and alfalfa can be grown successfully only where such an applica- 
tion is made. 
The Miami silt loam, in its different phases, is a fairly good general 
farming soil, suited to the growing of small grains and grass and 
giving fair to good results with corn. The flat phase is rather poorly 
drained and yields are generally low in years of excessive rainfall. 
It is also difficult to secure good yields under drought conditions be- 
cause of the tendency toward the baking of the surface soil. Under- 
drainage and the incorporation of large quantities of organic matter 
will tend to remedy this condition. 
The normal phase of the type is usually sufficiently rolling to have 
fair natural drainage, although some nearly level areas and many 
small depressed areas are in need of tiling. The rolling areas of this 
phase are adapted to a wide range of farm crops and are also better 
suited than any other part of the type to the growing of home 
orchards of winter apples and other fruits. The deep phase of the 
type is generally well drained and somewhat superior to other parts 
of the type, especially for corn production.
