CROPS AND SOIL IMPROVEMENT 



the fertilizers were applied immediately after the 

 first hay crop of the year was removed. Three 

 hundred and fifty pounds of acid phosphate and 

 50 pounds of muriate of potash per acre is the 

 mixture recommended. When old alfalfa plants 

 do not stand thickly enough on the ground, grasses 

 and other weeds come in readily. They can be 

 kept under partial control by use of a spring- 

 tooth harrow, the points being made narrow so 

 that no ridging will occur. The harrow should be 

 used immediately after the harvest, and will not 

 injure the alfalfa. 



It does not pay to use alfalfa for pasturage in 

 our eastern states because the practice shortens 

 the life of the seeding. 



Alfalfa makes a seed crop in profitable amount 

 only in our semi-arid regions. No attempt to 

 produce a seed crop in the east should be made.
