374 SOILS: PROPERTIES AND MANAGEMENT 



Substances Removed in Drainage Water from One Acre 

 of Land. Pounds in One Year 



It will be seen that the total solids in the drainage 

 water from the Arkansas land and from the planted 

 tank were not greatly different in amount, but that 

 some of the constituents differed greatly. This was 

 notably the case with organic matter and with lime. 

 The former was doubtless carried largely in the run-off 

 and not in the leachings. The latter was probably more 

 abundant in the glaciated soil used in the tank than 

 in the residual soil of Arkansas.
