Effects of Cover Crop Treatments on Apple Trees
<p>Ground cover management systems affect soil quality and health and thereby orchard growth and productivity. There have been few studies in the southern US on the effects of managed drive-rows using cover crops as part of a sustainable apple orchard management system. A field study used …

MEASURING AND MODELLING COVER CROP GROWTH AND AGRONOMIC EFFECTS
Cover crops are cultivated during the bare soil period between the harvest of a cash crop and the sowing of the next one. Their cultivation puts into effect the permanent soil organic cover principle of conservation agriculture and exerts several agro-ecological services, among which the most …

Cover crop management strategies for driver weeds in Kansas
… in the north central region to understand how cover crops influence weed suppression and seedbanks. As cover crops increase on farm production hectares, management strategies must be evaluated to discover which ones result in optimum weed control. The effects of cereal rye cover crop on Palmer …

Water Quality Impacts of Cover Crop/Manure Management Systems
Crop production, soil system, water quality, and economic impacts of four corn silage production systems were compared through a field study including 16 plots (4 replications of each treatment). Systems included a rye cover crop and application of liquid dairy manure in the spring and fall. The …

Cover crop residue effects on machine-induced soil compaction
Crop production systems which utilize the biomass produced by rye (<i>Secale cereale</i> ) to suppress weed growth and conserve soil moisture have been developed at Virginia Tech. The success of alternative, reduced-input crop production systems has encouraged research into the potential for …

Interactions between cover crop residue and microbial community affect weed suppression
… for agricultural weed control. Incorporation of cover crop residues is an important approach that contributes to alternative weed management systems. The cover crop residue-associated allelochemicals can inhibit weed germination, growth and production. Soil microbial communities are especially …

Influence of Cover Crop Termination Timing on its Volunteers and Weed Suppression
Cover crops are widely planted in the mid-Atlantic region for their environmental and agronomic benefits, but incomplete or delayed termination can lead to cover crops becoming weeds in the subsequent cash crop, known as volunteers. Studies were conducted from 2020-2022 to evaluate the effect of …

Estimating the Contributions of Soil and Cover Crop Nitrogen Mineralization for Corn
… include site-specific estimates of N supply from cover crops (CCs) or soil organic matter (SOM). Recent research successfully predicted the contribution of N from SOM and CCs to corn (Zea mays L.) in Pennsylvania. The objective of this work was to validate the biophysical model developed in …

Motivation, Challenges, and Farm Resilience: Examining Cover Crop Adoption using a Survey Approach
… highlighting soil health practices like cover crops key to boosting climate resilience. Despite cover crops benefit for soil health and sustainability, adoption remains low at ~5% in the USA. Cover crop adoption depends on a “complex web” of multilevel and multiple factors of …

Residual Nutrient Removal by a Winter Cover Crop From Broiler Litter Amended Soils
… is the possible nutrient build-up in pasture and cropland as a result of broiler litter application. Studies were conducted at Western Kentucky University using sorghum sudangrass (Sorghum bicolor (L.) Moench) as a forage to possibly remove excess nutrients. This project led to a consideration of …

Entomological considerations for domestication of pennycress, Thlaspi arvense, as a cash cover crop
… regions, is being domesticated as a winter cover crop and oilseed crop for the Midwest U.S. corn-soybean rotation. This domestication presents significant agricultural and environmental benefits; however, understanding of the interactions between pennycress and insect herbivore communities …

Fostering Populations of Arbuscular Mycorrhizal Fungi Through Cover Crop Choices and Soil Management
… of land plants, including many key agricultural crops, form a beneficial, symbiotic relationship with arbuscular mycorrhizal (AM) fungi. This has triggered interest in the potential role of these fungi in sustain-able food production for an increasing population. However, it is known that many …

Optimizing Weed Suppression Via Cover Crop and Herbicide Programs in the Mid-Atlantic
Many Virginia farmers include cover crops in their corn (Zea mays L.) and soybean (Glycine max (L.) Merr.) production due to government subsidies and agronomic benefits. Progressive farmers have optimized cover crop management for specific goals, such as weed suppression and nitrogen fertilizer …

Soil microbial community dynamics in response to cover crop implementation and P fertilizer management
… in response to management practices that include cover crop usage and P fertilizer treatments at an early transition to no-tillage (less than 5 years) site at the Kansas Agricultural Watershed Field Research Facility. Objective one examined soil samples from the spring and fall of 2018 and 2019 at …

Efficacy, Phytotoxicity, and Cover Crop Response of Herbicide Combinations in Dark Fire Cured Tobacco
… to evaluate efficacy, phytotoxicity, and cover crop response of herbicide combinations in dark fire cured tobacco. A randomized complete block design was used with nine treatments replicated three times. Hydroponic tobacco transplants (c.v. 'TND950') were established on May 20,1999 in a …

Measurement of Cover Crop Evapotranspiration and Impacts on Water Management in Crop Production Systems
<p>Cover cropping is a popular agriculture practice that provides many benefits to the soil and subsequent cash crops. However, eastern South Dakota lies in a transitional climatic zone between the subhumid climate to the east and the semiarid climate to the west, an area susceptible to both excess …

To Mix or Not to Mix: Performance and Management of Diverse Cover Crop Mixtures
Cover crops (CC) are planted in between cash crops to improve soil quality and to supply nitrogen (N) to cash crops through biological N fixation or soil N scavenging. Most producers use single species CC, in part because potential benefits of using mixtures of three or more CC species are poorly …
