COURSES FOR STUDENTS OF GRAZING 36 1 



experts, and, second, the widely trained agriculturalists and pro- 

 fessional foresters. The grazing expert naturally would be 

 expected to cover in detail the entire field of study here outUned, 

 but the general student of agriculture and the forest expert 

 would pursue only such broad grazing subjects as will be 

 mentioned later. 



The educational requirements for professional training in 

 pasture and livestock management should be equal to those for 

 other scientific professions. This implies thorough training in 

 auxiliary subjects. The following schedule of auxihary subjects, 

 including a statement of their application to the management of 

 pasture lands, has been proposed: ^ 



Subject Application 



Botany General management of all forage resources. 



Taxonomy Recognition of important, objectionable, and 



unimportant range plants. 

 Morphology (internal Structure pertinent to the forage value of plants 

 and external) and to revegetation. 



Physiology Response of growth and functions of plants to 



annual cropping. 



Ecology Relation of invasions and successions to range 



management. 



Plant pathology Control of parasitic diseases inimical to forage 



production. 

 Zoology General conception of animal life, animal rela- 

 tionship, and zoo-dynamics fundamentally es- 

 sential to the study of entomology, veterinary 

 science, etc. 



Bacteriology The application of soil flora to soil fertility and 



crop production. 

 Entomology Classification and life history of insects, espe- 

 cially as related to the genera and species de- 

 structive to forage plants. 



Chemistry Constituents of plants and animals; comparative 



nutritive qualities of forage plants and con- 

 centrates; soil-fertility requirements. 

 Geology (including soUs) . . . Relation of soils to intensity of grazing, revege- 

 tation, erosion, etc.
