and unfertilized soil, and it never will. Fertilizers, domestic and com- 

 mercial, should be considered in the nature of an investment that 

 entails but little expense after paying the first cost, and they generally 

 repay thb cost and a profit of from loo to 500 per cent. 



Think of it: We have shown that $8.00 worth of a well-balanced 

 fertilizer may be expected to increase the yield of seed cotton, on one 

 ^crc, 1,000 lbs., which are worth $30,00, leaving $22.00 of profit, or say 

 $20.00, which is 250 per cent, on the cost. 



. *'But such results can only be attained by concentrating the fer- 

 tilizer on the best land, not by scattering it at the rate of 100 or 200 

 lbs. to the acre over a large, worn-out plantation. These remarks 

 apply with more or less force to all crops, and especially to those re- 

 quiring a large amount of labor per acre, and particularly to cotton* 

 tobacco and garden crops."

"Experiments made the year before were coniinued, and it was 



found that by far the best results were obtained from a fertilizer which 



would analyze about as follows: 



Available Phosphoric Acid 10 per cent. 



Potash 4 



Nitrogen 3

'*In plot 14 there seems to be almost an unmistakable indication 

 of benefit from potash."

By S. M. Tracy, Director. Annual Report. Soil — Stiff clay, very 

 exhausted. 



*'It will be seen that the greatest increase of yield came from the 

 plots which received 200 lbs. of kainit per acre, and that this increase 

 was secured at the smallest expense per ico lbs. — 53 cents."

 By G. J. FiNLEY, Holly Springs Branch Station. Third Annual Re- 

 port. Soil — Upland clay soil. (Field No. i.) Kainit alone pro- 

 duced a profit of $10.58. 



"The yields from these plots indicate very clearly the necessity for 

 the use of potash fertilizers, and the still better results to be obtained 

 by the use of a fertilizer containing a fair amount of nitrogen and 

 phosphoric acid in addition. Plot 4, which received 200 lbs. of kainit, 

 gave the largest as well as the most profitable yield of any plot
