AI.FAI.FA. . . . The report of the Kansas state board of agriculture , which has just been published , is devoted to a discussion of forage plants , paying particular atteu- tion to alfalfa. Alfalfa is no longer an experiment. It has been established that it is peculiarly adapted to the soil and climatic conditions of the western states. THE CONSERVATIVE publishes the following relative to the preparation of the soil and the method of planting , as described by Geo. L. Clothier , M. S. of Manhattan , Kansas : "The most desirable soil for alfalfa is that of fertile creek or river 'bottom' land , well drained and not subject to inundation. Any soil which retains standing water on its surface forty-eight hours will not successfully produce alfalfa. With this reservation , I believe it safe to assert that it will grow on any soil that will produce corn , and on a good many soils where corn will not grow. It prefers a soil , however , that is rich in the mineral elements of plant- food , such as potash , lime , magnesia , phosphoric acid , and sulphur. A soil formed from decomposed limestone is ideal for the growth of alfalfa. It will also thrive exceedingly well in a soil composed of almost pure sand , provided the water table is within reach of its roots , and the underground water contains - tains enough mineral to supply it with a large quantity of its food. In central and western Kansas "alkali gumbo , " such as is frequently found on the creek bottoms of that section , is considered the most valuable alfalfa land. It is reported ns thriving close up to the edges of "alkali sinks , " on Mr. H. D. Watson's great ranch at Kearney , Ne braska. This is accounted for by the fact that the plant is a gross feeder upon some of the identical minerals compos ing the alkali. "In eastern Kansas , the clay subsoil apparently contains inexhaustible sup plies of plant-food for the growth of alfalfa. The difference in yields re ported from bottom laud and upland is not duo to a difference in fertility of the soil , but to a difference in the available water supply to the roots. Although alfalfa has been known to survive periods of excessive dryness in western Kansas so severe as to kill out the buffalo-grass , yet it is an undoubted fact that the plant uses as much water in the pro duction of a ton of dry matter as any other crop. Hence , if large yields are expected , the soil must bo such that largo quantities of moisture are avail able to the growing plants. Alfalfa is not likely to be a permanent and heavily yielding crop upon a soil underlaid with an impermeable substratum of rock or hard-pan within two or three feet of the surface. Preparation of tlio Soil In Kiintorii KUIISUH. The preparation of the soil should rightly begin two or three years before the time of seeding. In the older culti vated lands of eastern Kansas the soil should be freed from weed seeds by clean tillage with hoed crops , such as corn , potatoes , or roots. If the land is so weedy that it cannot bo cleaned by cultivation , it should be fallowed for one season prior to the seeding. If it is desirable to subsoil the land , this should bo done a year before seeding , and may be followed either by fallow or a culti vated crop. Time enough should inter vene between the subsoiling and the seeding to allow the soil to settle , and to store a bountiful supply of moisture against dry weather. "Although alfalfa roots penetrate very stiff soils , it generally pays to subsoil such to a depth of fifteen to twenty inches , so that the young plant roots may not meet with discouraging diffi culties too early in life. In a fairly porous soil o. vigorous alfalfa plant thirty days old will have a tap-root fifteen or eighteen inches long. The soil should be put in such perfect tilth that the farmer need have no fears of dry weather or weeds injuring his young alfalfa. The seed-bed should be as fine as an onion bed , and the subsurface be rather firm and well supplied with moisture. If the soil is deficient in humus , a liberal coating of barn-yard manure plowed under at the time of subsoiliug will add greatly to its physical condition , and thus help to start the young plants out in life with less diffi culties to encounter. If the soil is very sandy , the manure will be of great value in preventing the sand from blowing and in conserving moisture. A very sandy soil is not benefited by deep plow ing or subsoiliug. If the soil is heavy , and it is not practicable to subsoil , it should be plowed to a depth of eight or ten inches several mouths prior to seed ing. If the land is allowed to lie fallow after this treatment , or has been fall- plowed , it should be thoroughly disked every three weeks during the summer or autumn , as the case may be , to keep a dust mulch on the surface and prevent evaporation. "If the soil has had the thoroughly extended preparation outlined above , the immediate preparation will bo very simple , and may be accomplished by running a smoothing harrow over the ground a day or two before the drill. If there are dead furrows or ditches , or other inequalities of surface in the field that can be easily remedied , it will be profitable to give some time to leveling or smoothing the field so that the mower can bo run with comfort and safety over every foot of the ground. "If avoidable , alfalfa should never be sown on freshly plowed land. Yet , since it is the custom of many farmers to follow this more uncertain method , I will attempt advice for the alleviation of the difficulties likely to result : If such sowing is done in the fall the seed might just as well be thrown away. If , on the 1st day of May , one has a clean piece of corn stubble which he is anxious to seed at once , ho could in all probabil ity secure a better stand by thoroughly disking and cross disking the ground , and , after smoothing with a harrow , seeding without plowing. If it is neces sary to plow the ground , put on enough teams and do the work as rapidly and thoroughly as possible. Each afternoon go over all the plowing of that day with a Campbell subsurface packer or a similar implement , heavily weighted. The second day , in the forenoon , this ground should be given a thorough treatment with an Acme harrow , or with some other pulverizer , leaving a fine dust mulch on the surface. If the work is done rapidly evaporation will be so retarded that the ground will be in good condition for seeding after the first shower that moistens the dust mulch. Seed with a press drill , running a smoothing harrow over the ground before the drill to break up the crust that may have been formed. If ex cessive rains should occur within two weeks after seeding , as are frequent in May and June , 1 would expect to lose my seed , no matter how well put in , at this late spring season. It is not a good practice to sow after May 1 in eastern Kansas , unless it be in the fall. "The better way to prepare clean land for spring seeding is by fall or winter plowing. The ground should be disked a number of times at varying intervals before seeding , to keep it covered with the beneficent dust blanket. If the soil is likely to blow , the disks weighted down and set so as to ridge the ground may be made to prevent this. Ground prepared in this way , after receiving the immediate harrowing always necessary , should bo seeded early in April in the north half of Kansas. The preparation should qualify the soil to become a great sponge , drinking in the rains that fall , and giving this moisture back to the air through the leaves of the plants instead of through the surface of the ground. As alfalfa roots extend to great sub terranean depths , the rain-water should penetrate to these depths with facility. Time of Seeding. The time of seeding is of great im portance. This should be determined more by the absence of unfavorable con ditions than by the season. Alfalfa has been successfully sown in Kansas in every month from March to September. Where the ground is not weedy , spring seeding has been practiced with success. The cold rains of spring , however , when excessive , sometimes cause the young plants to rot off , as would be the case with the adult plant when submerged for two or three days. The farmer meeting loss in this way , in his dis couragement , then gives out the report that "alfalfa can't stand wet feet , " and will not grow in his locality. He forgets
