used with the same quantity of acid phosphate. The 

 240 pounds of cotton-seed meal contained more Nitro- 

 gen than 96 pounds of Nitrate, and cost more than the 

 Nitrate, yet did not give, as a rule, as good results. As 

 a rule, potash did not pay, except on sandy land. 

 While the "no fertilizer" acre gave only a small yield, 

 the best results were obtained from the combination 

 of Nitrate, phosphate and potash, but where the land 

 was fairly good, the potash did not seem to be 

 necessary. 



Cotton-seed meal has been an economical source 

 of Nitrogen, but it tends to make the soil sour, stale 

 and mouldy. Its use should never exclude the use of 

 Nitrate Nitrogen, i.e., Nitrate of Soda, at the rate of 

 100 pounds to the acre.
