If you need to feed/top dress two buckets of corn each day, get yourself 6-8 buckets. Put tight screens on the tops of these. Start with the first two - fill them with corn about 1/2 to 3/4 full (allowing for expansion). Fill with water and soak for 18 to 24 hours. Drain. Rinse each day, inverting to drain the water out and leaving on an angle to ensure they fully drain. At end of three to four days, you have sprouts.
If you fill two buckets each day with corn, then use the water from each to fill the rinse buckets, ending up with some very nutritious water which can be used on your potted plants or simply fed to livestock. Every four days, you feed out the corn in two of the buckets as top dressing for the feed. Extra protein and vitamins. Probably great for pregnant cows as well, keeping their weight up over winter.
Building some sort of swivels so that the buckets could be easily inverted would be the next step. Plus some sort of tray underneath to catch any drips (or simply raise an indoor garden underneath...)
Living and Raw Foods: Sprouting: a brief overview:
"Jars and Cloth: Two Suggested Sprouting Methods
Jars: use wide-mouth, glass canning jars, available at many hardware stores. You will need screen lids - cut pieces of different (plastic) mesh screens, or buy some of the special plastic screen lids designed for sprouting. Sprouting in jars is quite easy: simply put seed in jar, add soak water, put lid on. When soak is over, invert jar and drain water, then rinse again. Then prop jar up at 45 degree angle for water to drain. Keep out of direct sunlight. Rinse seed in jar 2-3 times per day until ready, always keeping it angled for drainage.
Cloth: soak seed in flat-bottom containers, in shallow water. When soak done, empty seed into strainer and rinse. Then take flat-bottom bowl or saucer, line bottom with wet 100% cotton washcloth, spread seed on wet cloth. Then take 2nd wet cloth and put on top of seed, or, if bottom washcloth is big enough, fold over wet seeds. Can add additional water to washcloths 12 hours later by a) sprinkling on top, or b) if very dry, remove seed from cloth, rinse, re-wet cloth, put seed back between wet cloths. Cloths used should be 100% cotton (terrycloth) or linen, used exclusively for sprouting, and of light colors. Cheap cotton washcloths (and cheap plastic bowls) work well and will last a long time.
