A description of characteristics for each species is included, as well as, other information on habitat, geographic distribution, potential toxicity problems, and similar species. This book also includes a vegetative key to the weeds, numerous identification tables, and a glossary. I spent some of my time at winter meetings reviewing the benefits of well thought out crop rotations that avoided long rotations of corn or alfalfa. Our experiences in the field in 1997 are reinforcing my belief in the need for a sound crop rotation plan. Here's my top ten list for rotations in 1997.
Rotations enhance no-till success.
Stand problems and delayed emergence in 1997 no-till corn on corn were common. Corn stands were better following other crops. Rotations reduce insects. This year corn rootworm beetles are high on corn following corn and corn rootworm damage is common- even on some treated fields. Rotations increase drought tolerance.
