FERTILIZERS AND FERTILIZING. 3H 



ble materials, without putting in some make-weight. This 

 is frequently done, land plaster and other materials being 

 used for the purpose. Land plaster, as a source of lime, 

 is valuable to some extent. Sand or other extraneous 

 matter is also used, but anything of this kind always 

 adds to the cost of handling. It is recommended that the 

 make-weight be omitted, in which case a smaller amount 

 of fertilizer should be applied to each tree, if the total 

 amount is less than one ton, and more if it is more than 

 one ton. Formula No. 1, for instance, without the make- 

 weight, calls for 1,614 pounds of material and this weight 

 contains as much actual phosphoric acid and nitrogen 

 as a ton weight of fertilizer analyzing 6 per cent phos- 

 phoric acid, 8 per cent, potash and 4 per cent, nitrogen. 

 It should then be used in place of one ton of fertilizer. 

 On the other hand some of the formulas call for more than 

 a ton of materials. These should be used as a ton would 

 be.
