The Rural Voice, 1988-06, Page 57completes its growth, it goes through a cycle of depleting and then storing food reserves in its roots. This stored food is necessary for each new growth and is essential to winter sur- vival. All new growth uses up food reserves for about three weeks. From then on, some of the food manufac- tured in the leaves, but not needed for growth, is stored in the roots. This reserve cycle is completed at the bloom stage, or about six weeks after growth begins. Soil Requirements ... Alfalfa has very little tolerance for poor drainage conditions. The crop will soon kill even where run-off water lies for only a few days during the spring melt. Alfalfa feeds heavily on calcium, and requires well -limed soil. Lime is also necessary for nodulation by N - fixing bacteria in the roots. A soil pH of 6.5 to 7 is desirable. Potassium and phosphorus are also very much needed for successful alfalfa production. A soil test is the best way to ensure proper levels of all these nutrients. Manure is an excellent fertilizer for alfalfa, although the N it contains is not needed by the crop and may be more useful elsewhere. (Never apply manure when the alfalfa is covered with snow, as ice frequently forms under the manure and spreader wheel marks, killing the plants.) The benefits of alfalfa, both as a valuable crop in itself as well as to succeeding crops, can be easily appreciated. It is known as the best source of economical, home-grown protein for livestock. Only through a full understanding of the peculiarities of this leguminous plant, however, can its benefits to agriculture be fully realized.0 KASCO Protective Helmets for Chemical & Dust Protections Bob cr Marilyn french SPRATEK ENTERPRISES R.R. 2, Mitchell, Ont.
