High Residue Cover Crops of Annual Weed Suppression in Corn and Soybean Production and Potential for Hairy Vetch to be Weedy

After termination, cover crop residue can suppress weeds by reducing sunlight, decreasing soil temperature, and providing a physical barrier. Experiments were implemented to monitor horseweed suppression from different cover crops as well as two fall-applied residual herbicide treatments. Results suggest that cover crops, other than forage radish in monoculture, can suppress horseweed more consistently than […]

Living Soil for a Sustainable Future: Cover Crop Effects on Soil Health and Productivity

The purpose of this study was to examine the effects of cover cropping on the soil biological and chemical features that contribute to soil fertility. The study looked at two summer cover crops –cowpea (Vigna unguiculata)and sorghum-sundangrass (Sorghum xdrummondii) in comparison with no-cover control –and their effects on soil respiration, soil organic matter and nitrogen […]

2018 Cover Crop Variety Trial

Boosting and maintaining soil health can provide a multitude of benefits to the farming operation. Cover cropping is a strategy that can be used to improve soil health. Cover cropping prevents soil erosion, maintain and/or improve soil nutrients, improve soil aggregation, prevent nutrient loss from runoff, and increase water retention. Such soil improvements can promote […]

Performance of Green Manure Species Seeded into Spring Barley

Producers have expressed interest in the best agronomic practices for cultivating spring barley and the use of interseeded cover crops (also known as green manures or living mulches) to increase barley yields and quality. Cover crops grown as living mulches grow with field or row crops to reduce weed pressure, prevent soil erosion, maintain and/or […]

Soybean Cover Crop Trial

As cover cropping expands throughout Vermont, it is important to understand the potential benefits, consequences, and risks associated with growing cover crops in various cropping systems. In an effort to support the local soybean market and to gain a better understanding of cover cropping in soybean production systems, the University of Vermont Extension Northwest Crop […]

Evaluating the Use of Forage Radish to Enhance Winter Rye Cover Crop Performance

As farmers in the northeast face ever-mounting pressure and desire to protect water quality, increase soil health, and maintain productive and sustainable farms, they are increasingly turning to cover crops as a way to accomplish these goals. This study evaluated whether the addition of forage radish (Raphunus sativus L. var. longipinnatus) to a winter rye […]

Interseeding Cover Crops In Corn Silage Cropping Systems

With increasing focus on managing environmental impacts from agriculture, farmers are looking for ways to minimize environmental impacts without sacrificing crop productivity. Cover cropping is one strategy that has been promoted to help retain nutrients and soil on farms to minimize losses to the environment. However, with the short growing season we experience in this […]

2016 Cover Crop Mix in Corn Silage Trial

Late harvest of corn silage can limit the ability to properly establish cover crops in the fall. Interseeding cover crops or earlier corn harvest can help get cover crops seeded earlier and help increase the overall benefits of the cover crop. In this trial, our goals were to evaluate the effect of three cover crop […]

2015 Cover Crop Mix in Corn Silage Trial

While growing corn silage,it is important to plan for soil health management during the season. Cover cropping is one way to prevent soil erosion, maintain and/or improve soil nutrients, improve soil aggregation, prevent nutrient loss from runoff, and increase water retention. Such soil improvements can promote conditions that add resiliency to a crop, especially in […]

2014 Summer Cover Crop Mix Trial

Many farmers have realized the multitude of benefits cover crops provide in terms of soil health and fertility. Most farmers, however, plant cover crops in the fall to protect their soils from erosion through the winter into spring while they do not have a crop planted. Summer cover cropping may be another option for growers […]

The Feasibility of Cover Crops in Dryland Cropping Systems in SW Colorado and SE Utah

This project stems from the need to protect our soil and water resources, reduce our dependence on chemical inputs, improve soil health and fertility, and increase dependable production of healthy foods. We hope to achieve some of these benefits by incorporating cover crops in dryland cropping systems and by doing so, enhance their sustainability in […]

Cover Crop Variety Adaptation Trials in Corvallis, OR Second Year Progress Report

Cover crops have the potential to provide many soil health and crop production benefits, but their success depends upon selection and use of species and varieties adapted to the local climate and soils. In order to evaluate the adaptation and growth potential of common, commercially available cover crop species and varieties, the NRCS Plant Materials […]

Allelopathic effects of small grain cover crops on cotton plant growth and yields

In west Texas, no-till planting cotton into rye or wheat cover crops reduced growth and lint yield of cotton compared with no cover crop. Production of allelopathic compounds, a known phenomenon in small grains, was suspected. Field and greenhouse trials verified cotton plant suppression by these small grain residues and by direct application of allelopathic […]

The Nebraska On-Farm Research Network approaches topics that are critical to farmer productivity, profitability, and sustainability. These topics include nutrient management, pest control, irrigation strategies, conservation programs, new technologies, soil amendments, cultural practices, and hybrid and variety selection.

COVER CROP IMPACTS ON SOIL MICROBIAL POPULATIONS AND NITROGEN CYCLING OF DRYLAND AGRICULTURAL PRODUCTION IN THE TEXAS ROLLING PLAINS

The Rolling Plains of Texas are characteristic of a low input, high risk environment with semi-arid conditions and sporadic, high intensity storms followed by periods of long drought. Agricultural practices that increase input costs are not readily adopted in the region; however, better management practices might be needed to tolerate global climate change. Cover crops […]
