You can grow alfalfa successfully on land which is from four to six feet deep if you irrigate rather more frequently and use less amounts of water each time, so that the plant shall be adequately supplied and yet not forced to carry its roots in standing water. The Eastern alfalfa grower is fortunate when he gets half the depth you mention, although it does seem rather shallow in California. Shallow lands are distributed over the valley quite widely. A deepening of the available soil is usually accomplished by dynamiting, especially so if the hardpan is underlaid by permanent strata. Alfalfa will penetrate some kinds and thicknesses of hardpan when it is kept moist, but not too wet, to encourage root growth. Winter-growing green crops are less affected by shallow soil because they generally make their growth while the moisture is ample, if the season is good. Curing Alfalfa with Artificial Heat. It is current rumor that "out in California they are hauling alfalfa green and curing it by artificial heat," thus reducing loss through bad weather and producing a superior hay for feeding or milling purposes. It is true that alfalfa is being cut green and dried by artificial heat, but this is only being done in preparation for grinding. No one thinks of doing it for the making of hay for storage or for feeding. This method is undertaken, not because the alfalfa hay does not dry quickly enough in the field, but because after drying in the field so many leaves are lost in hauling to the mill. We have no trouble sun-drying alfalfa for ordinary hay purposes; in fact, we have to be very careful that it does not get too dry. Cheap Preparation of Land for Alfalfa. I am about to put a piece of land into alfalfa, and want to use the most economical system of preparing the land for irrigation. My neighbors tell me that it will be necessary for me to have the land leveled; at a cost of $6 to $10 per acre. Now I am informed that in Alberta, and some places in California, they do not go to the expense of leveling land, but use a system of preparing land for irrigation at a cost of about 60 cents per acre. Nothing except a highly educated gale of wind, with discriminating cutting and filling ability of a very high order, could do it for that price. The cheapest way to prepare land for irrigation is the contour check method, which is largely used, or the flooding in strips between levees at right angles to the supply ditch; but neither of these could be put in properly for that money, even if the land was naturally in such shape that a minimum amount of soil-shifting is necessary. Where Alfalfa is Grown. In what counties is alfalfa most successfully grown? By this I mean where three crops of hay may be had each growing season. Also, will corn grow good paying crops in same sections?
