EFFECT OF BORAX ON COTTON AT MUSCLE SHOALS, ALA.® 
PLANTINGS ON COLBERT SILT LOAM. 
An experiment with cotton similar in plan to that at Arlington 
and at other locations with potatoes and corn was made on Colbert 
silt loam at Muscle Shoals, Ala. It included the application of 
fertilizer in the row as well as broadcast and also the immediate 
and delayed planting of seed after applying fertilizer. The quantity 
of borax used varied from 1 to 400 pounds per acre, and two rows 
each 70 feet long were used for each treatment. The fertilizers were 
applied on May 10. The rainfall for the month prior to starting the 
experiment and for a like period afterwards was exceedingly heavy. 
The soil became very compact from the excessive rains, and a very 
poor stand over the entire area was secured. The experiment was 
continued, however, in order to observe the effects of the borax, but 
a ead was not made, as the broken stand appeared to make it 
useless.
