The bright-yellow color of the soil indicates a lack of organic matter. 

 This can be corrected b}' plowing under green crops and by the applica- 

 tion of stable manures. The tendency toward puddling and baking 

 may be corrected by the application of lime. 



As has been, indicated in the comparison of this soil with the residual 

 soils of limestone areas, the Leonardtown loam is a type best adapted 

 to the production of grass and grain crops, and certain portions of the 



area found in St. Mary's County are at present producing good hay and 

 grain crops. The gradual introduction of live stock should largely 

 increase the producing capacity of this soil, since the crops best suited 

 to the soil can be fed directly to cattle. The saving in the fertilizer bill 

 in this connection is an important item in farm economics. 



The above analyses show the texture of the Leonardtown loam soil and 

 subsoil. 



The Susquehanna Gravel. 

 The layer of gravel which almost uniformly underlies the upland 

 soil types, particularly the Leonardtown loam, reaches the surface along 

 all the more deeply cut stream valleys and along the slopes separating
