APPENDIX E 



Definition of Treatment Needs 



An adequate drainage system is needed for the removal of excess 

 surface or internal water that interferes with the planting and 

 harvesting of crops. It does not include acreage in range and 

 pasture use that has excess water that is beneficial to both the 

 grazing resource and to wild life. 



Cultural or management measures only are needed to maintain the 

 proper air, water and soil relationship. It applies to irrigated 

 land only and there must be an adequate irrigation system to provide 

 for the proper application of water. 



Improved irrigation systems are needed for the proper application of 

 irrigation water to prevent soil loss and the over use of water needs 

 It includes such measures as the reorganization of existing systems, 

 land leveling, ditch lining, erosion control structures and drainage 

 for the removal of excess surface or underground water that interfer 

 with the planting and harvesting of crops. 



Irrigation water management is needed to control soil erosion and 

 prevent excess water loss, and to time water applications to meet 

 crop needs. It is presumed an adequate irrigation system is pro • 

 vided and management is the only need to achieve proper use. 



PASTURE AND RANGE 



No treatment needed - Pasture or range is adequately treated. (Plant 

 cover is in good or better condition based on the ecological aspects of 

 the site.) 



1. No treatment feasible - Pasture or range will not return a reasonable 

 benefit on the investment of conservation measures needed to improve 

 the site. Sites are usually barren shale or rock outcrop areas that 

 have limited plant cover and normal geologic erosion removing soil as 

 rapidly as it is formed. Some small isolated tracts of range in crop- 

 land areas are also included. 



2. Protection of plant cover from overgrazing - The pasture or range is 

 in an overgrazed condition but can be corrected by livestock manage- 

 ment and/or the installation of watering facilities to improve graz- 

 ing patterns. The desired vegetation is present but has been damaged 

 by overuse. With proper management and distribution of livestock, 

 the range or pasture will recover and improve by natural reseeding.
