Farm Types in Nebraska

200.12 acres of cultivated land in the Hitchcock area were 
about equivalent in 1909 to 83.19 acres of cultivated land in the 
Cass area. It is readily seen that this is a ratio of 100 acres 
to 41.6 acres, and that the crop index of the Hitchcock culti- 
vated land must therefore be 41.6 per cent. 
Wild hay occupies such a small acreage on the Hitchcock 
type of farm that there is little difference between the area 
of cultivated land and the area of crop land. This being true, 
it is not surprising to find that the crop index of crop land 
measures very nearly the same as the crop index of the culti- 
vated land. 
The value of land is here assumed to be in harmony with 
the normal yield of native pasture grasses. (Field studies 
in many parts of the State indicate that this is in general 
true.) If the inventory of live stock and the use of pasture 
in one area could have been directly compared with the in- 
ventory of live stock and the use of pasture in another area, the 
carrying capacity of the land rather than its value would have 
been used as an index to pasture yields. When pasture land is 
added to crop land the index to yields is decidedly lowered. 
This is especially true of western areas where the greatest 
difference exists between the quantity of plant growth on the 
land selected for crops and the quantity of plant growth on 
the land left for pasture.
