EFFECT OF BORAX ON COTTON AT MUSCLE SHOALS, ALA. 8 



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 harvest was not made, as the broken stand appeared to make it 

 useless.
