MISSOURI AGRICULTURAL REPORT. 



Using the same valuation as before, the increase from the com- 

 bination of acid phosphate with muriate of potash has had a total value 

 for each rotation of $18.02 per acre during the first period, and of 

 $26.08 during the second. Deducting the cost of the fertilizer we have a 

 net gain of $9.12 per acre for the first period and of $17.18 for the 

 second. 



When nitrate of soda has been substituted for muriate of potash the 

 increase has been as shown in table V. 



V.-AVERAGE INCREASE PER ACRE FRJM ACID PHOSFHATE AND NITRATE OF 



SODA. 



The increase from this combination thus shows a total value for 

 each rotation of $19.98 for the first period and of $35.24 for the second, 

 leaving a net value of $5.58 for the first period and of $20.84 ^of the 

 second. 



On the land receiving the complete fertilizer, made up of acid 

 phosphate, muriate of potash and nitrate of soda, the increase has been as 

 shown in table VI.

The total value of the increase in this case amounts to $25.72 lor the 

 first period and $42.47 for the second, leaving a net value of $4.82 for 

 the first period and $21.57 for the second. 



It will be observed that in every case the fertilizers have produced 

 a very much greater increase in the cereal crops during the second period 

 than during the first, while the hay crops have shown a marked falling 

 oflf in the rate of increase during the second period, except where nitrate
