SciiooL, Wetumpka, in 1901. 



Dark gray iQiim soil toith reddish siihsoil. 



This upland field is reported as having been cleared about 

 twenty years before of its growth of longleaf pines and small 

 water oaks. 



For the three years preceding the experiment it was un- 

 cultivated and grew up in grass and briers. 



There was little or no black rust. The stand was uni- 

 form. 



The average results indicate that the chief need was for 



phosphate. Neither kaiuit nor cotton seed meal was of 



much use the first year after the plowing in of large amounts 



-of vegetable matter,. The need for phosphate is also sug- 



jgested by the results of the 1'903 inconclusive experiment on 



-the same farm. See pages 47 and 71. 



The largest net profit was from plot 5, $4.65. 

 Increase of seed cotton pertecre when cotton seed meal was added:

To acid phosphate plot 116 lbs. 



To kainit plot 63 lbs. 



To acid phosphate and kaini-t plot — 93 lbs. 



Average increase with cotton seed meal 37 lbs. 



Increase of seed cotton per acre when acid phosphate was added: 



To unfertilized plot 170 lbs. 



I'o cotton seed meal pl®t 222 lbs.
