Finding the Balance Between Corn Yield and Cover Crop Biomass November 29, 2016

Cover crops can provide either ecosystem services or forage benefits but understanding how they fit in cropping systems is still limited. This study assessed the effects of planting date (early and late), plant population (low, average, and high) and corn maturity (80 to 115 days relative maturity) on corn yield.

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.

Student Research: Does the Grazing of Cover Crops by Cattle Compact Soil? November 2, 2016

Undergraduate Rebecca Clay shares the results of her study on whether grazing cover crops contributed to soil compaction at four sites in west central and eastern Nebraska. Clay, an undergraduate student in the Iowa State University Department of Agronomy, conducted the study as part of a UNL Research and Extension Experiential Learning Fellowship in summer 2016.

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.

Student Research: Cover Crop Effects on Soil Properties October 5, 2016

Undergraduate Andi Nichols shares the results of her study on how cover crops may affect soil properties. Nichols, an undergraduate student in plant and soil sciences at the Oklahoma State University Department of Agronomy, conducted the study as part of a UNL Research and Extension Experiential Learning Fellowship in summer 2016.
