The produce of an acre may be estimated by taking 15 lbs. as the average weight of each 
plant, and assuming that it will occupy a square yard. An acre will produce, according 
to the estimate, 36 tons, containing 30 tons of water and 6 tons of dry matter. The nitro¬ 
genous matter of an acre, according to the foregoing calculation, will be 357’6 lbs. in the 
green plant, and 2148 lbs. in the dry. A ton of the green plant contains 15*8 lbs. of in¬ 
organic matter, and 139'38 lbs. in the dry plant. There will be removed from an acre, 
569 lbs. of inorganic matter. A ton of the green plant contains 1768 lbs. to 232 of dry 
matter.
