The acreage shown in Wisconsin is mostly marsh hay and that in theWestern States is located largely in moist mountain valleys or on high plateaus(see Pig. 3). A Graphic Summary of American Agriculture. 451. Pig. 42.—Alfalfa demands soUk that are not add, and it is most cured in aclimate that is not rainy during the summer. Consequently, it thrives best m theWMtern States where it is grown mostly under irrigation, and fairly well in thelimlstoSe sections of the B^stf where its culture is increasing rapidly. This increasehf«, be?n notable in the slightly subhumid section of eastern Kansas and NebraskaSphere rtP acreage has increased over sixfold in the past 20 years. Alfalfa replaceswnd lay in th?sarea as the major hay crop. Seven-eighths of the alfalfa acreage iswest of tJie Missouri River (see Figs. 4, 6, and lb). 452 Yearbook of the Department of Agrictdture, 1921.
