This book discusses the difficult questions of fer- 

 tilizers in such plain and untechnical language that 

 those who are wholly unlearned in chemistry can 

 use it. There are no elaborate tables. The book 

 instructs upon the fundamental principles of the use 

 of fertilizers, so that the farmer is able, when he 

 reads it, to determine for himself what his practice 

 shall be. It is not an advocate for commercial fer- 

 tilizers, but tells simply and directly what the truth 

 is respecting their value. It explains the latest 

 results of experiments to determine what fertilizers 

 are best for given soils and given crops. 



FERTILIZERS includes the following : The Natural Fer- 

 tility of the Soil, and Sources of Loss of the Elements of 

 Fertility; The Function of Manures and Fertilizers, and the 

 Need of Artificial Fertilizers; Nitrogenous Fertilizers; Phos- 

 phates; Superphosphates and Potash; Miscellaneous Fertiliz- 

 ing Materials; Purchase of Fertilizers; Chemical Analyses of 

 Fertilizers ; Methods of Use of Fertilizers ; Fertilizers for 

 Cereals and Grasses, Potatoes, Sweet Potatoes, Tomatoes and 

 Sugar Beets ; Green Forage Crops ; Market -garden Crops ; 

 Orchard Fruits and Berries j Fertilizers for various special 

 crops.
