other use. The kinds of use are defined below and acreages were based 

 on the 1966 crop year. 



Irrigated Cropland is that acreage on which water is applied by an 

 adapted method on a recurring basis as an integral part of crop produc- 

 tion. It does not include land with water-spreading systems that are 

 dependent on runoff from shower activity. 



Non-Irrigated Cropland is that acreage to which no supplemental water is 

 applied on a recurring basis. It does include haylands on which water- 

 spreading systems provide some additional moisture from natural runoff. 



A. Cropland in tillage rotation 



1. Field Crops 



a. All row crops - Corn (grain or silage), sugar beets, 

 potatoes, beans, peas, vegetables and grass seed 

 cultivated in rows. 



b. Close growing field crops - Small grains and other 

 close seeded crops not usually grown in rows and 

 tilled. Includes wheat, barley, oats, flax, rye and 

 the like. It also includes the above crops if they 

 are cut for hay or temporarily used for pasture. 



c. Summer Fallow - Includes lands used primarily for 

 the production of close growing field crops in 

 alternate years. Lands are left idle for one year 

 to store the needed moisture to make crop yields 

 worthwhile harvesting in a semi-arid climate. 

 Although it is profitable to produce grain on an 

 annual basis in some areas, acreage allotments 

 have established a land use pattern of a fallow- 

 crop system. 



2. Rotation hay and pasture - Includes grasses and/or legumes 

 used for hay or pasture as part of a rotation system. 

 Lands must have been used for field crops at least one 

 year out of six, or hay and pasture stands reestablished 

 every five years to qualify. 



3. Hay land - Lands on which forage production is harvested 

 as hay rather than pastured. It includes grasses and/or 

 legumes not in rotation which are harvested as hay or seed 

 and then pastured or left to grow forage. It includes both 

 native and meadow grassland that are harvested as hay.
