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

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.

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

Cover crops for weed suppression in organic vegetable systems in semiarid subtropical Texas

Overall, the results indicate that cover crops, especially those with the ability to grow quickly and develop a closed canopy or known to have allelopathic properties, have the potential to control weeds in organic vegetable farms in semiarid subtropical Texas.
