VEGETABLE GARDEN IN a 



Ground limestone may be used to supply lime. This 



has the advantage of not destroying humus, as is the case 



with quicklime. The lime is not, however, given up as 



quickly to the plant, but gradually becomes available. 



COMPOSITION OF VEGETABLES AND MANURES 



In the following tables are shown the amounts of 

 fertilizing elements contained in vegetables and in the 

 various farm manures and commercial fertilizers. These 

 figures are from eastern United States and European 

 sources. The climatic conditions in these places are quite 

 different from those in many sections of the Western 

 states, where the actual amount of ash ingredients in 

 plants, especially in dry years, may greatly exceed the 

 amounts here given. The relation or these tables to one 

 another is worthy of special study, since they show what 

 the plants need and what the fertilizing materials supply.
