Fertilizing materials, E. B. Yoorhees, M. A. — This includes 

 the trade values of fertilizing ingredients for 1800, suggestions as to 

 the economical purchase and rational use of nitrogen, phosphoric acid, 

 and potash, formulas for mixtures of these ingredients for dift'erent 

 crojjs, and suggestions regarding the home mixing of fertilizers. 



It is not claimed that the buying of raw materials and mixing at home is the best 

 and cheapest method of getting fertilizers under all conditions; however, the import- 

 ant points in favor of the method will bear repeating, viz.: (1) that a definite 

 knowledge of the quality of the materials is secured; (2) that where farmers know 

 "what they want and unite in purchasing car lots, there is a decided saving in the 

 cost of the plant food. * * » 



It should be remembered in this connection that mtrogen, plwsphoric acid, and potash 

 are necessary for the full development of farm crops, and that the difi'erent crops have 

 different capacities for using them ; it is also true that when no increase in crop fol- 

 lows the proper application of any one or all of these elements, the crop has sources 

 at command which provide sufficient quantities to develop it to thatlimit fixed by the 

 existing conditions of climate and season. 



In view of these facts, the hestfertiliztr resolves itself into the best or most economi- 

 cal quantify of vilrogoi, p]io><2)lioric acid, or potash io be used uuder the varying conditions 

 of crop, soil, and seaso)i. * * * 



Individual farmers must determine for themselves whether for their land and their 

 crops single elements uiiiy not be more profitable than any combination of two or more; 

 the physical condition of the soil, and its previous cropping and manuring must also 

 guide the farmer in deciding whether the amounts given in the table should be 

 increased or diminished. As a broad, general rule, greater immediate profits are 

 secured from heavy dressings on land in a high state of cultivation than on farms of 

 average fertility.
