the lands with superphosphates plus green manure, 

 and got the following crops of oats : 



AVERAGE PER ACRE IN MAUNDS OF 80 LB. 



1st year . . . . . . 12 = 960 Ib. 



2nd year .. .. .. .. 19-5=11,56015. 



3rd year 23 = 1,840 Ib. 



This combination of manures supplied nitrogen and 

 phosphorus presumably there was sufficient potash 

 in the ground. On page 32 Mr. Davis states that 

 at Pusa the application of superphosphates only 

 had raised the crop of maize from " 10 maunds to 

 15 maunds per acre." By continued green manuring 

 plus superphosphates the crop of maize was raised 

 from 6 maunds per acre to 19 J maunds per acre. 

 He says that " in 1899, at Dalsingsarai, superphos- 

 phate manuring increased the crop of mustard seed 

 from 6 maunds to 27 maunds per acre, that is a gain 

 of 21 maunds per acre." 



In the Proceedings of the Board of Agriculture at 

 Pusa, December i, 1919, page 84, Anstead, Norris 

 and Samson reported that " India suffers from soil 

 exhaustion " due to " want of manure " " failure 

 to use human excreta," and also suffers from exports 

 of seeds, oil-cakes, bones, and they advise the 

 stoppage of these exports. On page 125 the following 

 figures are given : With no manure the crop of 

 maize was 752 Ib., straw 1,732 Ib. With green 

 manure and superphosphates the crop was 1,458 Ib. 

 grain and 2,841 Ib. straw. In the case of oats without 

 manure the grain crop was 562 Ib. and straw 1,175 Ib.
