CONCLUSIONS REGARDING THE USE OF FERTILIZERS. 



The Bureau of Entomologj'' has not conducted any special tests of 

 fertilizers. However, in the prosecution of a great number of the 

 general experiments, it has been necessary to make use of commer- 

 cial fertilizers. In view of the lack of exact knowledge regarding 

 the proper use of fertilizers in Texas, due to conditions which are in 

 many respects dissimilar to those in regions where experiments with 

 fertilizers have been conducted, it is considered advisable to present 

 some of the incidental results along this line. 



The uncertainty connected with field experiments during a single 

 season is nowhere more marked than in the use of fertilizers. The 

 benefits derived from the use of fertilizers depend upon soil and 

 climatic conditions, as well as upon the preparation the ground is 

 given. The climatic conditions may cause some fertilizers to be 

 available during one season, while during another season no results 

 might be evident from their use. During the season of 1904, the 

 results of the use of fertilizers were confusing. However, some of 

 the results that are doubtless of more or less general application are 

 referred to in the following paragraphs. That these conclusions are 

 approximatelv correct is shown by the fact that the}' agree in a gen- 

 eral way with the results of the various State experiment stations 

 which have conducted fertilizer experiments in the South.
