will be in blossom and should be care fully rut down, 

 and then a second will spring up, and in six or 

 eight weeks, may be as large as the first. Then 

 plow all in together, and by the 1st of Anjru>t, put 

 in sowed corn, as a mulch for wheat, as directed in 

 Chapter VII. 



Take notice to this remarkable fact, that we have 

 lour green crops, and the wheat actually put in the 

 "round, with only two plowings! 



If your soil should be a heavy clay, and you wish 

 to plow it thre^ 1 times, the rye may be turned in 

 about the middle of May, and Hungarian grass or 

 some other quick growing plant be sown for the Miird 

 crop. 



To conclude this subject, let us examine the 

 relative value of green buckwheat, compared with 

 barnyard manure. In the three crops which you can 

 plow in between two crops of wheat, it will be safe 

 to estimate them all together at 45 tons per acre. 



Then on a field of 20 acres, you will have 900 

 tons, containing 7200 pounds of nitrogen, 2700 pounds 

 of phosphoric acid, and 9900 pounds of potash. Now 

 it will Take 720 tons of stable manure to yield as 

 much nitrogen as we get in our triple crop of buck- 

 wheat. And nearly as much for the phosphoric acid 

 and potash. If the last crop of buckwheat, should 

 absorb any material from the mouldering ruins of 

 the first, it may be possible, that we only gain from 

 the soil about two-third.-; of the amount above given. 

 But that will be amply sufficient for a good crop of 

 wheat.
