FERTILIZERS AND AGRICULTURAL LIME 7 



potash, is a fair one if the comparison is confined to fertilizers to be applied to 

 soil. For hydroponic use, that is for growing plants in nutrient solutions or in 

 sand, etc., it is advantageous to use mixtures made from chemically pure water- 

 soluble ingredients. The cost of these ingredients is considerably higher than 

 that of similar commercial-grade fertilizer materials ordinarily used in the manu- 

 facture of solid fertilizers. This higher cost of raw materials must naturally be 

 reflected by a higher price on the mixed products.
