Borax ix Fertilizers. 



The large amount of loss due to borax carried in fertilizers 

 in 191 9 led to investigations by the Station. Preliminary results 

 have been published in Bulletin 288. And the results of a rather 

 extensive greenhouse investigation undertaken in cooperation 

 with the seven Stations in the Northeastern group of States is 

 practically ready for publication. 



Early in 1920 the Commissioner of Agriculture prepared 

 cards that were sent to all on the Department and Station mail- 

 ing lists urging that in view of the borax trouble of the preced- 

 ing year, farmers send samples to the Station for prompt exam- 

 ination for borax. 



All the samples sent by correspondent;; and the official sam- 

 ples were tested for borax. In most cases they carried no ap- 

 preciable amount of borax and in no instance was the amount 

 large enough to have, in the light of the experiments above re- 

 ferred to, toxic effect. While growers should continue to send 

 samples to the Station in accordance with the suggestion of the 

 Commissioner of Agriculture, there is little .likelihood that any 

 commercial fertilizer will again be offered with appreciable 

 amount of borax.
