﻿EFFECT OF BORAX ON GROWTH AND YIELD OF CROPS. 29 



The experiments on Caribou loam in Maine showed that 5 pounds 

 of borax applied in the drill at the time of planting produced 

 definite injury, but the methods of applying the fertilizer-borax 

 mixtures, such as early application before planting and broadcasting, 

 tended to reduce the degree of injury at the lower concentrations. 



While there was evidence of borax remaining in the soil for a 

 period of some months even with considerable rainfall, the injury 

 was practically confined to the drill rows with high initial application 

 of borax. In a commercial field under observation no injury could 

 be observed the second year after the failure of the cotton crop 

 caused by borax in the fertilizer used. 



In all of the work where comparisons were made, it was shown 

 that the potash salt from Searles Lake, Calif., when practically 

 free from borax, gave satisfactory results as measured by actual 

 yields.
