The stand of alfalfa secured is sometimes thin and uneven. This may arise from such causes as sowing too little seed; whether over-dry or through the crowding of the young plants. When this happens, in many situations it is quite practicable to thicken the stand by disking the ground more or less, adding fresh seed, according to the need of the crop, and then covering the seed thus added with the harrow. Such renovation would be comparatively easy on clean land, were it not for fact that the alfalfa plants already rooted overshadow the young plants, always to their injury, and sometimes to their total destruction. The spring will probably be the best season to attempt such renovation, but there may be instances where the winters are not severe, in which autumn seeding will succeed as well or better than spring seeding. Because of the uncertainty of the results of such renovation, the aim should be so to prepare the land and sow the seed that a good, thick stand will be secured at the first. Should the alfalfa fields be spotted, because in places the nurse crop lodged and smothered the plants, or because excessive moisture destroyed them on the lower portions of the field in an abnormally wet season, the renewing process is simple indeed. It consists in disking those parts so thoroughly as to destroy all vegetation that may have become rooted on them, and sowing seed in the usual way without a nurse crop. But should the low places be such as to hold an excess of water at any time of the year under normal conditions for days in succession, even though it should not rise to the surface, the attempts to make alfalfa grow successfully on these will prove abortive.
