The Sassafras sandy loam produced the best quality if not the best 

 yield — that is, more sugars, solids, and vitamin C. On the other hand, 

 the Edgemont stony loam gave the poorest quality. The sugars were 

 low, the titratable acids high, and vitamin C low. 



SOIL FERTILITY FACTORS 



The above-mentioned information shows that the quality of tomatoes 

 grown on different soil types varies. It is believed that the quality of 

 tomatoes, as influenced by soil types, is primarily a question of differ- 

 ence in soil fertility factors. 



Soils with obviously abnormal soil fertility factors were selected and 

 25 pounds of Rutgers tomato fruit were taken from each field for the 

 purpose of ascertaining the influence of fertility factors upon the quality 

 of the crop. Chemical analyses of the soils from these fields are given 

 in Table III. For example, the Adelphia sandy loam, a poorly drained
