7 he ash elememts which remain as solids when plants are 

 burned in the open air, also called the mineral or inorganic 

 part of the vegetable structure, though constituting a 

 very small part of plants, are nevertheless of prime import- 

 ance to the vegetable economy, and hence to the agricul- 

 turist. 



The following table shows the principal elementary sub- 

 stances, found in the ash of plants, and the compounds 

 which they form with oxygen, or with each other. With 

 the exception of sulphur, none of these elements are found 

 in nature, but they exist in the soil and in plants as com- 

 pounds with oxygen, or with each other. Since these com- 

 pounds are not found in the atmosphere, they must be 

 taken into the plant through the roots, and must, therefore, 

 be present in the soil in an available form to secure the 

 normal development of plants. 



Other elementary bodies occur in some plants in very 

 small quantities, but have no important relation to the 

 general vegetation of the farm.
