IDAHO
H. W. Kiefer, Bingham county.—I have grown alfalfa in Idaho, under irrigation, for 12 years. Have 40 acres on second bottom, heavy clay soil for 12 feet. This subsoil pulverizes by the action of the air, and will produce a good crop of small grain. Water is reached at 100 feet. The 12 feet of clay is dry; the gravel and sand below are more or less moist till water is reached. Land having produced two successive crops of small grain is preferred for alfalfa. Sow 20 pounds, in the spring, and cover lightly with harrow, brush, or drag, or roll. The plants should be vigorous enough to choke out weeds. Amount of hay obtained the first year is governed by conditions and treatment. When sudden freezing and thawing occur, it is liable to winterkill. The frequency of our irrigation is governed by the rainfall, but is usually done when the ground is dry, without regard to stage of growth, allowing the water to run until the soil is wet the depth of a spade; usually average two irrigations to each cutting. Our supply of water comes from Snake river and tributaries, which furnish sufficient for the Snake river valley. Have noticed no difference in amount of water required during first or later years, except as affected by the amount of rainfall. We get three cuttings, averaging about five tons for the season, cutting for hay when in bloom, and for seed when seed is matured, which generally requires the entire season to mature in this locality. The seed crop should be handled as little as possible, to avoid loss of seed. Alfalfa should cure at least two days, and, if dry, will not mold in stack. The cost of alfalfa hay, if irrigated, is about $2 per ton. Cost of baling, $1.75 per ton, in bales weighing 75 to 100 pounds, the keeping being governed more by the solidity than size of bale. During the past six years, hay has averaged about $4 per ton, in the stack, and seed about 8 cents per pound. Alfalfa makes satisfactory pasturage for sheep and horses. Cattle are liable to bloat, but, if taken in time, may be relieved with a gag, and by exercise which will cause the gases to escape; the knife is used as a last resort. The straw from which seed has been threshed has about the same value as green oat straw. The various soils here appear equally favorable to longevity. Usually the third year gives about the best yield. If not damaged by freezing, it will not need reseeding for 10 or 15 years. We have no trouble in ridding land of alfalfa. We cut a hay crop, and plow under, for spring wheat, with good results. Our best alfalfa land is clay, which requires moisture, artificial or natural. Our best yields have been six tons per acre for the season. The feeding qualities of the hay have been well established.
James Otterson, Logan county.—Have had 12 years’ experience growing alfalfa on sagebrush land, that will grow nothing but sagebrush without irrigation. It is fine, sandy loam, extending down 6 to 10 feet, where lava is encountered, which is from 1 to 100 feet deep. The soil is dry until water is struck, which is at a depth of from 100 to 200 feet. There is no water in the soil. When preparing for alfalfa, we plow well, level the ground, and sow 15 to 20 pounds of seed per acre, and harrow lightly, or brush it in. Sow as early as the ground can be worked—about March 1. The first crop, if properly handled, will yield from three to five tons per acre; it will have more or less sunflowers, which are a protection while the plant is getting a start. It seldom winterkills. We irrigate by flooding the ground twice each season from a stream. After the first year, three cuttings are had; 21⁄2 tons per acre the first; 11⁄2 to 2 the second; and one ton per acre the third. Cut for hay as soon as well blossomed. It grows too rank here for seed. Hay should cure in from one to two days, and, if properly cured, stack as other hay. Alfalfa costs, in stack, $3 per ton. The size of bales is immaterial, except in fitting cars. Prices for hay have ranged from $5 to $10 per ton; for seed, from 7 to 15 cents per pound. It is the best hay in use for farm animals. Horses will thrive on it without grain, if properly handled. For swine pasture it is far ahead of clover. It is satisfactory for sheep. In some localities it will cause cattle to bloat; as a preventive, feed well with dry hay before turning them on the pasture. Deep soil is the best for the long life of the plant. The second year it is at its best, and, if properly handled, and does not winterkill, will last for all time. It is much better than Red clover for green manure.
