uncertain for all the requirements of 

 modern agriculture, for it is not available for use for a 

 whole year or even longer. The rapid exhaustion of 

 combined Nitrogen has several times been noticed by 

 eminent scientific men, with reference to food famine, 

 because of a lack of the needful Nitrogenous plant food.

 upon forever. 



This injudicious waste is already reducing the yield 

 of many of the best lands, rendering the use of at least a
