Theoretically, this fertilizer ought not to contain azote; potash 

 ought to be exhibited in the form of a carbonate. The nitrate of 

 potash is substituted on account of the price. The quantity of azote 

 introduced in the fertilizer rises to only 24 pounds the acre, and is too 

 small a quantity to be injurious. 



I now pass to cultures by rotations.
