Abstract Organic producers in the mid-Atlantic region of the USA are interested in reducing tillage, labor and time requirements for grain production. Cover crop-based, organic rotational no-till grain production is one approach to accomplish these goals. This approach is becoming more viable with advancements in a system for planting crops into cover crop residue flattened by a roller–crimper. However, inability to consistently control weeds, particularly perennial weeds, is a major constraint… 

Cover Crop-Based, Organic Rotational No-Till Corn and Soybean Production Systems in the Mid-Atlantic United States

Cover crop-based, organic rotational no-till (CCORNT) corn and soybean production is becoming a viable strategy for reducing tillage in organic annual grain systems in the mid-Atlantic, United

Overcoming Weed Management Challenges in Cover Crop–Based Organic Rotational No-Till Soybean Production in the Eastern United States

Abstract Cover crop–based organic rotational no-till soybean production has attracted attention from farmers, researchers, and other agricultural professionals because of the ability of this new

Integrated Weed Management Strategies in Cover Crop—based, Organic Rotational No-Till Corn and Soybean in the Mid-Atlantic Region

Testing the cumulative effects of a multitactic weed management approach in a 3-yr hairy vetch/triticale—corn—cereal rye—soybean—winter wheat CCORNT rotation indicates that HR cultivation is necessary to achieve adequate weed control in CCOR NT systems.

Using mulch from cover crops to facilitate organic no-till soybean and maize production. A review

Sustainable cropping systems that balance agricultural productivity and ecological integrity are urgently needed. Overreliance on soil tillage and herbicides to manage weeds has resulted in a number

Extreme Grain-Based Cropping Systems: When Herbicide-Free Weed Management Meets Conservation Tillage in Northern Climates

Overall, flexible crop production programs such as the former Manitoba Pesticide Free Production program and the “Agriculture raisonnéeTM” program in Québec are more likely to promote sustained environmental, economic, and social prosperity than rigid adherence to organic or no-till practices.

Fall-sown cover crops as mulches for weed suppression in organic small-scale diversified vegetable production

Abstract Cover crop-based reduced tillage (CCBRT) has achieved positive impacts in organic row crop systems, contributing to the conservation of soil resources and the facilitation of weed

A Comparison of Reduced Tillage Implements for Organic Wheat Production in Western Canada

Low-tillage systems are needed to improve soil conservation in organic farming. This study evaluated three no-till/low-till cover crop termination strategies on the basis of weeds, N dynamics and

No-till seeded spinach after winterkilled cover crops in an organic production system

Abstract 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,

Investigating tarps to facilitate organic no-till cabbage production with high-residue cover crops

Abstract High-residue cover crops can facilitate organic no-till vegetable production when cover crop biomass production is sufficient to suppress weeds (>8000 kg ha−1), and cash crop growth is not



Potential long-term benefits of no-tillage and organic cropping systems for grain production and soil improvement

There have been few comparisons of the performance of no-tillage cropping systems vs. organic farming systems, particularly on erodible, droughty soils where reduced-tillage systems are recommended.

Integration of soil, crop and weed management in low-external-input farming systems

Summary Greater adoption and refinement of low-external-input (LEI) farming systems have been proposed as ways to ameliorate economic, environmental and health problems associated with conventional

Legume Cover Crop Contributions to No-Tillage Corn Production

To identify optimum corn fertilizer nitrogen (FN) rates following cover crops, hairy vetch, Austrian winter pea, crimson clover, and wheat were evaluated.

Effects of tillage intensity on nitrogen dynamics and productivity in legume-based grain systems

In 1988 an experiment was established at the Rodale Institute Experimental Farm to study weed control and nitrogen (N) management in rotations with grain crops and N-fixing green manures under

Effects of a grass-selective herbicide in a vetch-rye cover crop system on corn grain yield and soil moisture

A 2-yr study evaluated a grass-selective herbicide applied in late March to a pure rye cover and a vetch-rye mixture, allowing the vetch to accumulate N until early May, and found corn grain yield was greater following pure stands of vetch than following any other cover crop treatment, regardless of kill date.


This article reviews literature about the impacts of cover crops in cropping systems that affect soil and water quality and presents limited new information to help fill knowledge gaps. Cover crops

Is conservation tillage suitable for organic farming? A review

Conservation tillage covers a range of tillage practices, mostly non‐inversion, which aim to conserve soil moisture and reduce soil erosion by leaving more than one‐third of the soil surface covered

Nitrogen fertilizer timing and application method affect weed growth and competition with spring wheat

Abstract Managing crop fertilization may be an important component of integrated weed management systems that protect crop yield and reduce weed populations over time. A field study was conducted to

Control of cereal rye with a roller/crimper as influenced by cover crop phenology.

Predicting when cereal rye can be successfully controlled using a roller/crimper along with the use of the thermalbased phenological model should aid growers in decision-making regarding cereal rye planting and termination dates.

"No-Till" Farming Is a Growing Practice

Most U.S. farmers prepare their soil for seeding and weed and pest control through tillage—plowing operations that disturb the soil. Tillage practices affect soil carbon, water pollution, and
