APPENDIX E 



Definition of Treatment Needs 



CONSERVATION TREATMENT NEEDS 



The treatment needs data are mutually exclusive by types of treat- 

 ments to avoid overlapping of acreages. Even though problems occur in 

 combinations that require two or more such treatments, only the more 

 severe problem based on the kind of farm operation is considered in the 

 acreage estimate. It is assumed that good soil management practices 

 such as fertilizing and the addition of soil amendments where needed 

 will be over and above those treatments provided for in the treatment 

 categories for cropland. 



Needs were based on judgment of trained conservationists in line 

 with local technical guides used to achieve the proper use and manage- 

 ment of our soil and water resource, 



CROPLAND 



Adequately treated land is land on which the current conservation 

 treatment is adequate to meet the conservation problem. This applies 

 to both irrigated and non-irrigated use. 



1. Crop residue, annual cover crops or other annual recurring measures 

 used locally only are needed to meet the conservation problem. Hay- 

 land requiring stand improvement but not establishment is included. 



2. Sod in crop rotation only is needed to meet the conservation problem. 

 Hay land needing reestablishment is included. 



3. Contouring only is needed to control soil erosion and reduce runoff 

 when land is in cultivated crops. This requires farming operations 

 to be done on the contour. 



A. Strip cropping, terraces, or diversions are needed to treat and 



protect the land in addition to other measures needed to supplement 

 these practices. This includes strip cropping of all kinds, and 

 diversion that may be needed on long slopes. Complete terrace 

 systems for water erosion control or for conservation of water are 

 needed when strip cropping alone is not adequate to meet the conser- 

 vation problems. Acreages needing a system of sod waterways or 

 windbreaks are included. 



5. A change to a permanent cover of grass or trees is needed for better 

 use of the land. Lands unsuited for intensive cultivation should be 

 in a perennial cover most of the time to protect the soil resource.
