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 
ee ron borax, gave satisfactory results as measured by actual 
yields.
