56 VEGETABLE FORCING 



the very small percentage of organic matter as compared 

 with the Boston greenhouse soil. The Ashtabula soils 

 are famous for their production of lettuce and cucumbers, 

 and tomatoes are also grown to a considerable extent in 

 this soil. 



Cleveland soils. The best vegetable forcing soil of the 

 Cleveland district is known as the Dunkirk fine sandy 

 loam. Although not quite so coarse in texture as the 

 Dunkirk sandy loam used at Ashtabula, it is highly 

 satisfactory for the growing of lettuce and tomatoes. 

 Cucumbers are also grown in this soil to some extent. A 

 mechanical analysis shows the following results : 



Fine gravel 0.7 



Coarse sand 2.7 



Medium sand 3.7 



Fine sand 39.5 



Very fine sand 32.4 



Silt 11.2 



Clay 9.2 



Toledo soils. The typical trucking soils of the Toledo 

 district belong to the Miami series. The Miami sand is 

 best adapted to vegetables. It is variable in composition, 

 but contains, according to mechanical analysis made by 

 the U. S. Bureau of Soils : 



Gravel Less than one per cent 



Coarse gravel 1.64 to 3.74 



Sand 7.08 to 24.74 



Fine sand 37.66 to 51.34 



Very fine sand 5.50 to 33.54 



Silt 5.45 to 15.60 



Clay 2.54 to 3.59 



Lansdale silt loam. Tomatoes are grown quite ex- 

 tensively in this soil, near Lansdale, Pa. It is regarded 

 as a good soil for general farm crops. The drainage is 

 good and the soil does not puddle very easily. The 

 following is a mechanical analysis of the soil :
