plants as alfalfa, or upon timothy meadows where the root is good 

 but a lack of nitrogen is apparent, an application of 100 pounds an 

 acrp will often give an increase in the crop of from 1,000 to 2,000 

 pounds of hay. 



Phosphoric acid and potash are best applied in and not on the 

 soil as they become fixed very near where they are left. Lime and 

 the nitrates work down into the soil and may be applied on top or 

 near the surface of the ground. 



For the profitable growing of all kinds of leguminous plants tho 

 use of lime has become necessary on nearly all soils, especially those 

 in southern New York. 



The use of salt on the land is practiced by some farmers, ah 

 though on many crops its benefit is very doubtful. The results 

 obtained from its use could, in many cases, be more economically 

 obtained by lime or other substances. Often its application is 

 clearly detrimental. Five hundred pounds an acre should be the 

 maximum used. 



Whenever a farmer applies any such material he should always 

 leave a check and carefully note results. In this way he can deter- 

 mine for himself whether or not it was a profitable investment.
