Implementation of Cover Crops in Corn and Soybean Systems in Nebraska November 29, 2016

A short review of cover crop research conducted at four University of Nebraska research fields (two irrigated, two dryland) to study the feasibility and impact of winter cover cropping on soil quality, soil water, and crop yields in corn-soybean systems. Objectives were to quantify cover crop emergence, fall and spring biomass production, soil water changes, soil chemical and physical property changes, and crop yields.

Forage, Feed, and Grazing Restrictions for Row Crop Herbicides November 1, 2016

As the end of corn harvest nears, some producers will soon be turning their cattle into corn stalks or cover crops to graze. Before taking this step, take time to review the labels from in-season and fall-applied herbicides for any grazing restrictions.
