MANAGEMENT OF SPECIAL SOILS 291 



(2) Mixed farming, which may provide for the utiliza- 

 tion of the native vegetation, and which permits the use 

 of (1) grain crops for hay, (2) Swede turnips for suc- 

 culent winter feed, and (3) the profitable use of frost- 

 damaged grain as feed. 



(3) The use of early classes of grain crops, such as 

 oats, barley or rye in preference to wheat ; and the use 

 of early varieties such as Prelude or Ruby wheat ; sixty- 

 day, Orloff or Daubeney oats; Early Six barley and 

 Early White peas. 



(4) Soil management practices that result in earlier 

 germination or earlier maturity such as (a) packing the 

 land, (b) less frequent fallowing, (c) shallow plowing 

 of the fallow, (d) later plowing of the fallow, and (e) 

 the use of manure to warm up cold soils. 



(5) Thicker seeding No combination of practices 

 will result in preventing damage to grain crops from 

 summer frosts, but a few days earlier maturity may les- 

 sen the probability of injury from fall frosts. Thick 

 seeding results in somewhat earlier maturity of the crop.
