(c) Climate is a limitation In terms of temperature and moisture as 

 it affects the choice of crops and systems of fanning. Much of the 

 cropland in Montana has less than 120 days growing season and annual 

 precipitation received necessitates a fallow system of dryland farming 

 in much of the State. Soils having only a climatic limitation are of 

 high quality and not subject to erosion under proper management. About 

 34 percent of the dry cropland and nearly 19 percent irrigated cropland 

 in Montana has climate as its major limitation.
