harvesting of the crop. The best growers, especially upon well- 
drained land, obtain yields which range from 18 to 25 bushels. 
These are decidedly profitable, and beans should constitute an im- 
portant field crop upon all of the better drained and more porous 
members of the Clyde series of soils. 
CABBAGE, ONIONS, AND CHICORY. 
Cabbage is grown on a small acreage upon several types of the 
Clyde series. Upon the Clyde sand and fine sandy loam cabbage is 
produced for local markets and constitutes an early special crop. 
The yields range from 8 to 14 tons per acre and the crop is ready for 
market in August or early September. The total acreage, thus 
grown, is small and confined to the near vicinity of city markets. 
Cabbage is also grown as a shipping or storage crop upon the 
heavier members of the Clyde series, particularly upon the Clyde 
loam, clay loam, and silty clay loam. The acreage on the Clyde loam 
is small, but the yields obtained are fair. A production of 8 to 15 
tons per acre of marketable heads is common. 
The Clyde clay loam and silty clay loam are far more extensively 
used for cabbage growing than any other members of the series. In 
the vicinity of Racine, Wis., several hundred acres of cabbage are 
annually grown, both for the local city markets and for shipment to 
southern cities. Danish Ball Head, Flat Dutch, and other shipping 
varieties are chiefly planted. The crop is grown in regular rotation 
with other field and truck crops and the average yields vary from 10 
to 15 tons per acre, dependent upon seasonal variations, chiefly. It 
has been found that cabbage should follow onions in the truckers 
rotation, while they may be grown upon clover sod or after corn in 
the general farming rotation. Cabbage should not be grown more 
frequently than once in four years upon the same land in either rota- 
tion. This interval is essential to assist in the control of fungous 
diseases. It is a good practice to lime the land where cabbage is to 
be grown, using either a ton of burned lime per acre or an equivalent 
in the form of 2 or more tons of ground limestone. The source of 
supply for the latter material is near at hand in the case of the 
Racine, Wis., area and not usually remote in other instances. Stable 
manure, plowed under in the fall before, the crop is planted, consti- 
tutes one of the best fertilizers for cabbage, while various commercial 
fertilizers in moderate amounts are used by some truckers. Usually, 
the general fertility of the soil is chiefly depended upon for the grow- 
ing of cabbage upon the Clyde soils. The yields obtained are high 
under these circumstances. Wherever there is a fair local market or 
an opportunity to ship to advantage, cabbage growing might well be 
extended upon the heavier soils of the series.
