Hyt. When turned under green, has a 

 slight fertilizing influence, but not equal to its 

 cost. 



Spurrey. Woght's Spurrey is much used, 

 and with good results. If a field is consecu- 

 tivel}^ sown, and turned under green in March? 

 June and August, the effect of these three 

 herbages will equal 2,600 lbs. manure per 

 acre. This plant thrives only in sandy soils 

 and moist climates. 



Buck-wheat. According to Schwartz,Buck- 

 wheat, in Germany, is never turned under 

 until all hopes of a harvest are lost. Its (dry) 

 straw contains 0.54 of Nitrogen, and 0.48 

 after having been further dried in the air. 



Madia Sativa. This plant has been used, 

 as a green manure, by many farmers. Bous- 

 singault and Payen consider, that the resinous 

 exudations, enveloping it, render necessary a 

 maceration previous to its being turned under. 

 The fanes of this plant contain 0.66 per ct. of 

 nitrogen, in a dry state, and after being fur- 

 ther dried in the air 0.53. 



Rape-seed. This, of all other plants, has 

 been, and is the most generally used, as a ma- 

 nure. Its seed has the great advantage of being 

 cheap, and 10 to 15 lbs. suffice to sow an acre*
