Undersowing Red Clover Into Winter Wheat as an N Source for Corn

In 2011/2012, 2012/2013 and 2013/2014, we grew red clover in an organic soybean-winter wheat-corn rotation near Mead, NE with the goal of providing N to the following corn crop. The results from the drought year 2012/13 are not included because red clover failed to grow. We compared red clover to a control that did not […]

Perennial Row Mow Project

Woody Van Arkel, Long time cover crop user and striptill/notill farmer Right now I’m trying to develop a perennial/row crop system to try to meet my goals 1 keep the soil covered as much as possible 2 keep a living root system in my soil for 365 day/yr 3 do as little tillage as possible

Spring-planted Cover Crops for Weed Control in Organic Soybean

Weed control in organic soybean usually includes frequent pre-plant tillage operations but spring rains often make it difficult to get into the fields for timely tillage. As a result, weed pressure can be high. Cover crops can help suppress weeds, but after corn harvest it is often too late to establish cover crops. Spring-planting cover […]

Considerations when Planting Green

An increasing number of growers are ‘planting green’ or have asked questions regarding this practice. ‘Planting green’ means the corn or soybean is planted directly into a growing cover crop (most often a small grain like rye or wheat) without killing it by herbicide or mechanical means first. Research on this topic is limited but […]

Dryland Cover Crops as a Grazing Option for Beef Cattle

A two-year grazing study was conducted to evaluate forage quality and utilization of cover crops (CC) in dryland cropping systems compared to crested wheatgrass pastures (CWP). The CC mixture consisted of oats, peas and turnips planted in March with a no-till drill

Double-cropped cool-season annuals (cover crops) for late fall and early spring forage

The cropping systems that offer the greatest chance of success for realizing fall forage production from a forage double-crop are those following wheat, hybrid seed corn, and corn silage. Planting winter sensitive species (such as oats, spring varieties of other cereal grasses, and brassicas) between August 10th and September 10th in Nebraska can result in […]

Cover Crop Options after Corn or Soybean Harvest

In drought conditions there is less residue than normal in many fields. In some, the crop was harvested as a forage or cut as silage, leaving very little residue at all. Without residue to absorb the energy of raindrop impact and keep the wind off the soil surface, soil erosion will be greater and surface […]

Cover Crops for Storm-Damaged Fields

Fields that were hailed, flooded, wind-blown, or where planting was prevented this season need cover crops for all of these reasons since a growing crop isn’t achieving these purposes now. A key soil health concept is that there should be something green and growing during as much of the year as possible (Figure 1). This […]

5 On-Farm Cover Crop Studies from 2014 Show Varied Results

Five growers worked with the Nebraska On-Farm Research Network in 2014 to assess the use of cover crops for their farming operations. Specifically, these producers were concerned with the impact of cover crops on the yield of the subsequent cash crop. The cover crop mixtures and cash crops varied by location. The results of these […]

Long-term UNL Study Examines Impacts of Cover Crops on Soil, Water

Through a $1 million USDA-NRCS grant, UNL Water Resources Engineer Suat Irmak and his research team have been conducting trials in multiple fields since 2012. This research will help identify quantifiable, predictable, and actionable relationships between cover crops and related management practices and between cover crop growth and termination timing for maximum soil fertility and […]

Corn and Soybean Herbicide Options for Planting Cover Crops for Forage in Fall

It can be difficult to find information on which herbicide(s) to use or avoid for certain cover crops, especially when planning to use the cover crop for forage or feed (forage double crop). Due to the crop rotation interval specified on the label, the herbicides listed below can be applied in corn or soybean and […]

Study Initiated on Cover Crops in Corn and Soybean Systems

Researchers at UNL are working on a new study funded by the Nebraska Corn Board and Nebraska Soybean Board to investigate the effects of integrating cover crops into soybean and corn cropping systems. The team working on the project includes researchers in Lincoln, Concord, Clay Center, and North Platte with expertise in cropping systems, soil […]
