soils. Its application upon heavy loam or clay lands should be par- 

 ticularly beneficial, since the sandy nature of this marl would 

 improve the texture of the soil while its chemical elements supplied 

 essential plant foods. 



The Collington sandy loam is justly recognized as a good soil for 

 general farming operations, but its adaptability to special crops is 

 only partly realized. It is an area excellently adapted to market 

 gardening and medium and late truck crops. It produces fruits of 

 excellent quality and its special adaptation to the production of 

 nursery stock is already utilized. It should also furnish excellent 

 crops for canning factory purposes. 



The present system of general farming practiced on this soil type 

 should give place to a much more specialized type of agriculture, 

 accompanied by a decrease in the average size of the land holdings 

 and by much greater profits per acre. 



The following table gives mechanical analyses of typical samples 

 of soils and subsoils of Collington sandy loam :
