GENERAL OUTLOOK. 



The fertilizer requirements^ of the leading field crops of Louisiana 

 and the best method of restoring fertility to worn-out soils are sub- 

 jects that have occupied prominent places in the investigations of the 

 Louisiana stations ever since their organization. The fertilizer experi- 

 ments conducted simultaneously at the three stations during the past 

 decade indicate that nitrogen is the element most needed by the soils 

 of Louisiana for the production of every crop grown and that phos- 

 phoric acid is next in importance. The best method of restoring fer- 

 tility has been found to be a system of rotation of crops, in which 

 legumes figure prominently. Closely connected with these investiga- 

 tions is a systematic soil survey of the State, in which the officials of 

 these stations have been engaged for a number of years. A geological 

 survey of the State is also going forward under station auspices, 

 special attention being given to sources of artesian water supply. The 

 principal crops receiving attention are sugar cane, cotton, and tobacco, 

 and with each of these a great deal of valuable work has been done. 

 At the same time other crops are receiving attention and considerable 

 effort is being directed to the introduction of the live-stock industry. 

 The work is vigorously and intelligently prosecuted and is increasing 

 in importance from year to year.
