Food Plot Crop Rotation
Filed under: Ask Grant
Dr. Woods, Thank you for answering my previous questions. You did such a good job I have another question. I was recently told that I should not plant a brassica in the same field for more than two consecutive years because the field will get a fungus and will not produce. Is that true? We have enjoyed much success with brassicas (especially turnips). There are a couple areas right in front of stand sites that we have planted in brassica the last two years and would like to do so again next year. I understand crop rotation is best, but since it is a fall annual and we fertilize do I need to be concerned with the fungus? Once again, I really enjoy your site and the knowledge you share. Thanks, Jeff
Jeff,
Yes, crop rotation is an excellent practice for several reasons! Different crops pull different micronutrients from the soil. An intensive regime of soil analysis and adding trace minerals in the fertilizer is necessary to partially compensate for a less than desirable crop rotation program.
Another reason to rotate crops is to reduce the buildup of crop-specific pests. Rotating crops breaks the life cycle of many pests (but not all). Planting the same crop repetitively allows crop-specific pests to multiply rapidly. I’ve never noticed any more of a problem with brassicas than any other common food plot crop. You should consider planting clover or a small grain crop (wheat, rye grain, or oats) for a year to benefit from the practice of crop rotation!
Growing Deer together,
Grant
