IV. TURNING IN GREEN CROPS AS A MANURE. 



For the best experiment of turning in green crops as a ma- 

 nure, on not ler* than one acre, - - fifteen dollars. 

 For the second best, - - - - ten dollars. 

 For the third best. . . - - five dollars. 



REMARKS. 



The claimants must give a particular account of their res- 

 pective processes, and the results. The object aimed at is, to 

 ascertain whether land can be manifestly improved by turning 

 under green crops, and to what degree enriched. Each experi- 

 menter will follow his own judgment in his process ; but the 

 following intimations may merit his attention. 



The turning in of green crops is a very ancient, though not a 

 very general practice. Its utility has lately been called in ques- 

 tion. Hence the desire to bring it to the test of fair experiment. 

 Take an acre of land, so far exhausted at the last crop as to 

 render it inexpedient to introduce another without a good ma- 

 nuring. Plough it in the spring, and sow it with oats, barley, 

 buck-wheat, or millet — and not be sparing of the seed. When 

 the crop shall be full grown, but still in blossom, plough it in, 

 and sow it again. When this second crop shall be full grown, 

 plough it in. The next year repeat this process — again plough- 

 ing in two crops ; the last by the beginning of October. It may 

 then be sown with winter rye, to produce a crop of grain at the 

 next harvest — sowing five or six pecks, because sown so late. — 

 Or it may lie till the ensuing May, and then be planted with In- 

 dian corn. The product, compared with the last of the same 

 acre, prior to the commencement of the experiment, especially 

 if a crop of the same kind, will show the value of the green 

 crop ploughed in. 



ANOTHER MODE. 



The acre being divided lengthways into two equal parts, plough 

 the whole uniformly in the spring. Sow on one part two bush- 

 els of oats or of barley, or a bushel of buck-wheat, or three or
