Tillage and cover cropping effects on soil properties and crop production
Cover crops (CCs) have been heralded for their potential to retain nutrients in the field and improve soil properties, but their adoption within the Midwestern Corn-Belt remains limited. We assessed the effects of integrating five sets of CCs into corn-soybean rotations under no-till and chisel …

Effect of winter cover cropping practices on maize yield and nutrient cycling
… and phosphorus from an annual rye winter cover-cropped treatment to a conventional tillage control (fall chisel and spring field cultivation) by measuring preseason fertility, nutrient flux in subsurface tile lines, end of season soil fertility, and crop yields for each treatment. Best …

Optimizing nitrogen fertilization practices under intensive vineyard cover cropping floor management systems
Under-trellis cover crops have become more prevalent in East Coast grape growing regions through either intentional planting or adoption of native vegetation, to minimize the potential for erosion and to help regulate grapevine size and vigor. These companion crops, however, have sometimes resulted …

Cover Cropping: A Strategy to Healthy Soil and Nitrogen Management in Corn
… in order to improve crop N management decisions. Cover crops have been recognized as an effective tool for protecting soil and enhancing soil function including N cycling. This recognition has increased the adoption of cover cropping in the United States. Despite this growing popularity, there is …

The effects of winter cover cropping on nutrient leaching through repacked soil columns
Winter cover cropping has been identified as a conservation practice with the potential to decrease nutrient transport from agricultural fields, which consequently reduces nutrient loading to water bodies, eutrophication, hypoxia, and degradation of local ecosystems. This study utilized …

Exploring the motivations, practices, perceived benefits and challenges of cover cropping among Stellenbosch winegrowers
ENGLISH ABSTRACT: Cover cropping is an effective practice for improving biodiversity and agroecosystem functioning in vineyards. Understanding the factors that influence winegrowers’ decision-making around cover cropping would help guide future research and agricultural extension services to …

Global meta-analysis and metagenomics approach on the soil microbiome associated with cover cropping
… that threatens future global food security. Cover cropping is a promising sustainable agricultural method with the potential to enhance soil health and mitigate consequences of soil degradation. As one of the agricultural practices that can affect cover cropping, effects of tillage on cover …

Soil microbial aspects of cover cropping as conservation practice for corn monocultures under heavy nitrogen fertilization
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2022-11-15 without embargo terms

Agroecological approaches to warm-season cover cropping in northern climate vegetable systems and building collaborations with farmers
Summer cover crops are a management tool that vegetable farmers can use to counteract the negative effects of soil degradation by physically protecting soil, contributing biomass to soil organic matter (SOM), suppressing weed growth, and enhancing nutrient cycling, but their use may be limited in …

Root restriction, under-trellis cover cropping, and rootstock modify vine size and berry composition of Cabernet Sauvignon
… included root manipulation, under-trellis ground cover, and rootstock. Treatment levels were root bag (RBG) or no root manipulation (NRM); under-trellis cover crop (CC) or herbicide strip (HERB); and one of three rootstocks: 101-14, Riparia Gloire, or 420-A. Effects of these treatments were …

Cover Cropping on the Canadian Prairies: A Mixed Methods Study to Gain Understanding of Cover Crop Agronomic Practices Among Farmers
Cover crops (CC) can provide multiple benefits to farmers and society by reducing greenhouse gases, improving soil health and regional biodiversity, increase climate resiliency, and provide ecosystem services. However, currently within the Canadian Prairie agriculture systems, the recent use of CC …

Exploring Diversified Vineyard Ecological Soil Management Strategies: Impacts of cover cropping, Spanish River Carbonatite, and smooth pigweed (Amaranthus hybridus) interactions on an agroecosystem
… of an agroecosystem, forms the base for cropping systems and how it is managed matters. My research focused on investigating how two ecologically-based soil management techniques, cover cropping (using a species mixture of Cichorium intybus, Raphanus sativus, Medicago sativa, Trifolium …

Mapping agroecosystem management practices from space and quantifying their impacts on crop productivity
… agricultural management practices, including cover cropping and planting dates, is very limited. Recent advances in satellite remote sensing provide a promising solution for detecting field-level, long-term, and large-scale agricultural management practices. Thus, this dissertation aimed to …

Relationships among Root Traits, Nitrogen Availability, and Mineral-Associated Organic Carbon
… root traits, nitrogen (N) fertilization, and cover cropping influence soil organic carbon (SOC) and MAOC. In the first chapter, a greenhouse experiment with 30 herbaceous plant species found that non-N-fixing plants exhibited stronger positive correlations with MAOC compared to N-fixing …

Effect of an alternative viticulture on native entomopathogenic nematodes and other organisms linked to their soil food web in DOCa Rioja vineyards
… is one of the most intensively managed cropping systems. Therefore, approaches rather than reliance on mechanization and agrochemicals are needed to achieve more sustainable viticulture. We hypothesized that alternative strategies to tillage for soil management and the release of …

Nitrous oxide emissions under different corn field managements in the United States
… between plots differing in fertilizer rate, cover cropping, and tillage. In addition, corn fields in Illinois, Minnesota, and Colorado were modeled using the process-based Denitrification Decomposition (DNDC) model, which is used to predict trace gas emissions from agriculture based on field …

Integration of High Residue/No-till and Farmscaping Systems in Organic Production of Broccoli
High-biomass cover cropping enhances marketable yields in organic production of vegetables, linked to the improvement of soil quality and weed control. Although, during transition from chemical to organic cover-cropping production, especially with no-till systems, reduction of nitrogen availability …
