GROWING SUGAR BEETS IN COLORADO.

Fort Morgan (Table IX). The higher acre cost for the former area 
has undoubtedly been due to the fact that the disk was used more 
often there than at Fort Morgan.

Occasionally extra work is done on plowed land in order to accom- 
plish some of the objects which have been referred to under disking. 
On all fall-plowed land weeds may appear early in the spring and some 
cultivation must be given in order to keep the field clean. In this 
study three farms were found that reported tillage operations not 
common to other farms. Two growers in the Rocky Ford district 
used the cultivator, followed by a clod masher. The operation was 
done in 1914 and 1915 with a crew of one man and three horses at a 
cost of 95 cents per acre. One farm in Weld County reported some 
special cultivation with a crew of one man and two horses, at a cost of 
28 cents per acre, 
LEVELING. 
To insure a uniform distribution of water, the surface of the field 
must be smooth and free from depressions. The land leveler (fig. 7) 
accomplishes this result. It takes the soil from the tops of small 
knolls and deposits the material in any slight depressions that may 
exist. Some operators make a practice of leveling diagonally across 
the field, and if this process is repeated at right angles the surface is 
usually left without any serious inequalities. However, leveling also 
serves the purpose of a float, in that it crushes many ol the small clods 
that are frequently present on the recently plowed field. Ninety- 
eight per cent of the growers who are referred to in this study reported 
on leveling, hence it will be seen that this practice was almost uni- 
versal on these farms.
