These deep sandy soils are very open and droughty. The underlying 

 material consists of beds of varying sizes of sand, mostly of granitic origin. 

 Gravelly material is present in some cases. These soils were formed from 

 materials deposited by our present streams. The lower lying areas are sub- 

 ject to frequent overflow during normal high water, although this usually 

 occurs before spring seeding and after harvesting. The very coarse sandy 

 character of these soils permits water to move freely throughout the upper 

 part of the soil and the underlying material. Where these soil areas are 

 only a few feet higher than the adjacent streams, the depth to the water 

 table makes for a somewhat better moisture relationship than is found for 

 similar soils lying at a much higher elevation above the streams. In their 

 natural state, the very droughty condition puts them in the low potential 

 bracket for agricultural production, although a little more than one fourth 

 of this land is used for crops at the present time. Soil-building rotations are 

 a necessity in farming these soils. The presence of streams adjacent to these 

 soil areas provides the definite possibility of irrigation to improve the 

 poor moisture relations. For irrigation to be profitable, the land must be 

 limed, fertilized, and manured. Streambank erosion control is a major 

 problem that needs careful consideration.
