For tlio sandy soil of the fields used the following formula for a standard, normal 

 fertili/er is proposed, the standard amount beinjr 1,2(10 pounds per acre, used in two 

 applications: 



Pounds. 



1 f) per cent acid phosphate 1, 200 



S pi-r cent upland meal 400 



1!> per cent nitrate of soda 200 



')) per cent muriate of potash 200 



In the application of 1,200 pounds of such a fertili/er to an acre, the land would 

 receive the following amounts of plant food: 720 pounds of acid phosphate, 240 

 pounds of cotton-seed meal, 120 pounds of nitrate of soda, and 120 pounds of muriate 

 of potash. 



In order to ascertain the hest manner of applying the above formula and also the 

 quantity per acre that would jrive the most profitable results the following applica- 

 tions of this mixture were made to plats 1 to 10, inclusive:

To ascertain the relative importance of each of the plant foods, and as a ruide to 

 the mo.-t desirable proportions to be used, the following experiments are to be made 

 on plats Nos. 12 to 17, inclusive, in which each ingredient is omitted and doubled in 

 turn. Two applications of the fertili/er will be made:
