dressing of 50 to 75 pounds of nitrate of soda per acre may be applied. 

 When the plants are free from rain or dew, this will usually be found 

 to be profitable. 



With the high or moderately high phosphoric acid soils, the amounts 

 of phosphoric acid in the fertilizer mixture might in many cases be 

 reduced. Especially would this be so when the organic-matter supply 

 of these soils has been materially increased.

With all the mixtures given above, as the amount of organic matter 

 turned back into the soil is increased, especially that from leguminous 

 crops that are being grown on the land with the formation of nodules 

 on their roots, the amounts of cotton-seed meal and other nitrogenous 

 fertilizing materials required in the fertilizer mixtures to give most 

 profitable returns may be materially reduced. In fact, when the supply 

 has become liberal in the soil it might possibly be entirely left out of 

 the fertilizer mixture in nitrogen-carrying nuiterial. It should be the 

 aim of every farmer in the county, as nearly as practicable, to obtain 

 this condition with his soils, for under normal conditions nitrogen is 

 the constituent that is most expensive and the one that is most elusive, 

 and thereby easily lost from the soil when the conditions in the soil are 

 not just right. 



CROP ROTATION NECESSARY FOR A PERMANENT SYSTEM OK AGRICULTURE 



IN THE COUNTY 



It is the duty of every owner of farm lands in this county, as well as 

 of other counties in the State, to follow methods of crop rotation and 

 fertilization that shall at least maintain the producing power of the 

 soils and build up tlio.se that are yielding only small returns at the pres-
