laud small crops of peas may be turned under green and greatly im- 

 prove the texture of the soil, besides the addition of the fertilizer 

 constituents of the pea. The safest way with moderate size and largo 

 crops is to cut them with a disk harrow or some other implement, 

 allow them to wilt or even dry on the soil, and then turn them under. 

 On light soils the trouble is likely to be more serious, and here it is 

 especially necessary to either cut up large crops or else allow them 

 to remain on the soil until after frost, and even into the winter or 

 early spring. On heavy, as well as light land, this practice is good, 

 as the vines will then become at least partially decomposed and can 

 be turned under during the winter or before planting in the spring. 

 There may be some loss from remaining on the surface, but this will 

 in all likelihood be overcome if not exceeded by prevention from 

 washing. 



The large hay-yielding varieties, as the Iron, Clay, Unknown and 

 Whippoorwill, are best suited for soil improvement.
