Abstract Organic systems in the southeastern USA offer unique challenges and solutions to crop production due to regional soil and climate characterized by highly weathered soil types, high precipitation and the capacity to grow cover crops in the winter. Recently, the interest of producers and researchers in high-residue cover crops and conservation tillage systems has increased. Various designs of the roller–crimper to manage cover crops have been invented and demonstrated to growers in the… 

Cover Crops for Weed Management in Southern Reduced-Tillage Vegetable Cropping Systems

Investigation is necessary to identify appropriate cover crop and tillage systems for use in other agricultural settings, such as vegetable crops and organic production systems, and resultados promisorios in varios sistemas.

Cover Crop Effectiveness Varies in Cover Crop-Based Rotational Tillage Organic Soybean Systems Depending on Species and Environment

In a changing climate, future research should focus on establishing flexible decision support tools based on multi-tactic cover crop management to ensure more consistent results with respect to cover crop growth, weed suppression, and crop yields.

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

Organic zero-till in the northern US Great Plains Region: Opportunities and obstacles

Abstract The use of killed cover crop mulch for weed suppression, soil erosion prevention and many other soil and crop benefits has been demonstrated in organic no-till or zero-till farming systems

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

Screening Five Fall-Sown Cover Crops for Use in Organic No-Till Crop Production in the Upper Midwest

Organic no-till systems continue to draw interest from organic producers across the upper Midwest in the United States. Fall-planted cover crops, terminated in the spring through the use of a

Tillage System and Cover Crop Management Impacts on Soil Quality and Vegetable Crop Performance in Organically Managed Production in Tennessee

. Research is lacking on the impact of alternative reduced tillage (RT) systems on vegetable crop performance and soil quality, especially in organic production systems, where weed control cannot

Cover crops and compost prevent weed seed bank buildup in herbicide‐free wheat–potato rotations under conservation tillage

It is concluded that subsidiary crops, mulches, and potentially compost are important management tools that contribute to the success of RT in herbicide‐free cereal‐based systems in temperate climates.

Agro-ecological services delivered by legume cover crops grown in succession with grain corn crops in the Mediterranean region

Abstract Grain corn is the main cereal produced in Portugal. It is grown in intensive monoculture cropping systems that may have negative effects on soil quality, affecting long-term fertility and

Conservation Agriculture in Organic Farming: Experiences, Challenges and Opportunities in Europe

Conservation tillage includes a range of tillage practices, mostly non-inversion, which aim to reduce soil erosion by leaving the soil surface covered by crop residues. Despite conservation tillage

The Role of Cover Crops in North American Cropping Systems

SUMMARY The benefits of cover crops in cropping systems have long been recognized. Legumes have historically been used lo provide biologically fixed nitrogen to cash crops, and it has been shown that

Cover crops and living mulches

Abstract Cover crops and living mulches bring many benefits to crop production. Interest in winter annual cover crops such as winter rye and hairy vetch for ground cover and soil erosion control has

Crop Productivity and Economics during the Transition to Alternative Cropping Systems

Many environmental benefits accrue from reducing tillage and increasing crop diversity; however, economic factors often encourage the continued use of intensive tillage and specialized crop

Timing of Cover-Crop Management Effects on Weed Suppression in No-Till Planted Soybean using a Roller-Crimper

It is found that the degree of synchrony between weed species emergence and accumulated cover-crop biomass played an important role in defining the extent of weed suppression.

Comparison of mechanical and chemical winter cereal cover crop termination systems and cotton yield in conservation agriculture.

Results showed that rolling followed by reduced glyphosate rates as low as 0.42 kg ae/ha can effectively and reliably terminate mature cereal winter cover crops; thus maintaining cotton population and protecting growth.

Rolled Rye Mulch for Weed Suppression in Organic No-Tillage Soybeans

Rising demand for organic soybeans and high price premiums for organic products have stimulated producer interest in organic soybean production. However, organic soybean producers and those making

Nitrogen Release from Grass and Legume Cover Crop Monocultures and Bicultures

Results of this study demonstrate only slight reductions in N release from grass-legume bicultures compared with legume monocultures.

Impact of Rye Rolling Direction and Different No-Till Row Cleaners on Cotton Emergence and Yield

Cover crops have been recognized as a vital component of conservation agriculture. However, cover crops must produce substantial biomass to be effective. Because of the large amount of residue
