as corn meal, shorts and middlings. The combinations are vastly 

 superior to the prepared fertilizers on the market, chiefly because 

 they are entirely soluble and contain a high per cent, of potash." 



The general conclusions of all the experiments are summed up as 

 follows: "On an average, on New Hampshire soils and with general 

 crops, li.oo invested in the best prepared fertilizers has given an in- 

 crease of crop valued at $2.34, while $1.00 invested in the chemicals — 

 dissolved bone black, muriate of potash and sulphate of ammonia — 

 has given an increase valued at $3.56, a difference of $1.22 in favor of 

 and due entirely to the substitution of chemicals for prepared fer- 

 tilizers, at equal cost." 



The difference is due chiefly to the wrong proportions of plant-food 

 in the prepared fertilizers, and more to the deficiency of potash than 

 any other cause —

 "Few if any of the brands of mixed fertilizers have as high a per- 

 centage of potash as most truck crops require, and the practice of 

 home mixing of the fertilizer ingredients is annually becoming more 



common."

"For soils containing an abundance of lime, but little phosphoric

"The results are so marked as to strongly indicate that for corn 

 potash is a fertilizer needed on the soil of the Experiment Station Farm. 



"This holds true for potatoes also. The results on hemp and 

 tobacco prove the same to be true of these crops, and there are strong 

 indications that the wheat will be greatly benefited by the application
