The Cecil sandy loam is capable of being built up to a higher state 

 of productiveness by deeper plowing, increasing depth gradually, better 

 cultivation, and by the incorporation of green manuring crops, such 

 as clover, cowpeas, and soy beans. The clay subsoil enables the soil to 

 hold the improvements, and beneficial effects of manures are quite lasting.
