Effects of Cover Crops on Pratylenchus penetrans and the Nematode Community in Carrot Production

Cover cropping is a common practice in U.S. Midwest carrot production for soil conservation, and may affect soil ecology and plant-parasitic nematodes—to which carrots are very susceptible. This study assessed the impact of cover crops—oats (Avena sativa), radish (Raphanus sativus) cv. Defender, rape (Brassica napus) cv. Dwarf Essex, and a mixture of oats and radish—on […]

2019 MSU Cover Crop Variety Test Report

Cover crops have great value for improving soil and controlling weeds in many types of cropping systems. This variety test aims to provide information on suitability of cover crops in Michigan.

Cover Crops & Green Manures

Cover crops are grown to protect and/or enrich the soil rather than for short term economic gain. When turned into the soil, a cover crop is called a green manure, so the terms are reasonably interchangeable.

Getting Legume Cover Crops to Work in Mid-Atlantic Field Crop Rotations

The purpose of this project is to evaluate a novel cover crop interseeder technology, which allows growers to drill cover crops into a standing soybean crop. This practice could transform growers’ ability to integrate legume cover crops into a grain rotation and offset inorganic nitrogen fertilizer needs in the corn phase.

No-Till Seeded Spinach After Winterkilled Cover Crops in an Organic Production System

Organic no-till (NT) management strategies generally employ high-residue cover crops that act as weed-suppressing mulch. In temperate, humid regions such as the mid-Atlantic USA, high-residue winter cover crops can hinder early springfield work and immobilize nutrients for cash crops. This makes the integration of cover crops into rotations difficult for farmers, who traditionally rely on […]

Nitrate Leaching from Winter Cereal Cover Crops Using Undisturbed Soil-Column Lysimeters

Cover crops are important management practices for reducing nitrogen (N) leaching, especially in the Chesapeake Bay watershed, which is under total maximum daily load (TMDL) restraints. Winter cereals are common cool‐season crops in the Bay watershed, but studies have not directly compared nitrate‐N (NO3–N) leaching losses from these species. A 3‐yr cover crop lysimeter study […]

Evaluation of Cover Crops Drill-Interseeded into corn across the Mid-Atlantic

This article reports on field experiments that addressed two primary objectives: (1) compare cover crop establishment and biomass production of drill-interseeded grass and legume cover crops and corn performance across the Mid-Atlantic region and (2) determine if timing of interseeding cover crops into corn (V2–V6) influences cover crop performance and corn grain yield.

INTERSEEDING COVER CROPS INTO DOUBLE-CROP SOYBEANS – INITIAL FINDINGS

The mid-Atlantic region has the highest percentage of arable acreage in cover crops in the United States, with some reports placing Maryland and Delaware as the two states with the highest percentage of total cropland planted with cover crops (Wade et al., 2015; Hamilton et al., 2017). However, the majority of producers in the region […]

Cover Crops Impacts on Louisiana Corn Production and Soil Properties

Conventionally managed, continuous monoculture row-crop production has depleted the soil of nutrients, organic matter, and overall productivity. This has increased the need for external inputs, specifcally N, to meet crop demand. Despite the growing interest in conservation practices, including minimal tillage and cover crops, little work has been reported in the Mid-South region.

Cover Crops and Cover Crop Mixes: Stratification of Biological Effects

The potential nutrient cycling benefits from legumes (e.g. N2-fixation) and the high biomass potential of cereal rye are well known. Further studies are warranted to evaluate bi-culture mixtures and their effects on soil nutrient stratification and microbial enzyme activity because these two properties may be differently expressed (enhanced) by legume/grass mixes. The objectives of this […]

INTERSEEDING COVER CROPS TO SUPPRESS WEEDS IN CORN-SOYBEAN ROTATIONS IN KENTUCKY

Cover crops are typically sown between cash crops and can suppress weed emergence and growth. If cover crops are sown after cash crop harvest the system is left susceptible to weed emergence while they establish. Interseeding cover crops into a standing cash crop may limit this bare period by allowing cover crops to become established, […]

Biomass Production of Single Species Cover Crop

Cover crops can benefit agricultural production by improving soil health and productivity, reducing weeds, and providing biomass for grazing. In this one-year study, biomass production was measured in 17 different single species summer cover crops and a fallow control.

Using Cover Crops as an Effective Weed Control Method in Southeast Kansas

Weed control is important to optimize crop production. This study was conducted to compare the effectiveness of different methods of fall-implemented weed control strategies. These strategies included different cover crop mixes, chemical control, and mechanical control. The cover crop mixes included four different commonly-planted winter cover crops.
