the fall application of manure resulted in a greater saving of moisture 

 than the spring application. Some of the pots to which manure was 

 applied evidently had something wrong with them and did not allow 

 the water to percolate as it should. This is particularly true of the 

 Miller fine sandy loam, and also the Lufkin fine sandy loam.
