Herbicide Carryover to Cover Crops and Evaluation of Cover Crops for Annual Weed Control in Corn and Soybeans
While cover crops are actively growing, they compete with winter annual weeds. Studies were conducted to determine the ability of early planted cover crop monocultures and mixtures and a fall applied residual herbicide to compete with winter annual weeds. Cereal rye containing cover crops provided …

Technological Innovations for Mid-Atlantic Cropping Systems
… risk of lodging and made only after the barley crop has broken dormancy and a substantial increase in air temperature is not forecasted in the week following application. Chapter two compared the efficacy of eight vegetation indices calculated from three satellites (Landsat 8, Sentinel 2, and …

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 …

Using Winter Annual Cover Crops in a Virginia No-till Cotton Production System
… (<i>Gossypium hirsutum</i> L.) is a low residue crop, that may not provide sufficient surface residue to reduce erosion and protect the soil. A winter annual cover crop could alleviate erosion between cotton crops. Field experiments were conducted to evaluate selected winter annual cover crops …

Soil quality in organic cropping systems
… to organic production. Four studies examining crop yield, soil quality and weed control were conducted in Boone County, MO on a Mexico silt loam soil (fine, smectitic, mesic Vertic Epiaqualfs) from 2012-2014. Achieving a cover crop biomass sufficient for weed suppression was a challenge when …

High Residue Cover Crops for Annual Weed Suppression in Corn and Soybean Production and Potential for Hairy Vetch (Vicia villosa) to be Weedy
After termination, cover crop residue can suppress weeds by reducing sunlight, decreasing soil temperature, and providing a physical barrier. Experiments were implemented to monitor horseweed suppression from different cover crops as well as two fall-applied residual herbicide treatments. Results …

Value of Cover Crops in Suppressing Weeds and Protecting Cotton Yields and Likelihood of Residual Herbicide Carryover to Cover Crops
… conducted to investigate the potential for using cover crops to suppress problematic weeds in cotton as well as chemical options for cover crop dessication, and sensitivity of cover crops to residual herbicides were evaluated. No differences were observed for cereal rye biomass production and …

Nitrogen Management and Weed Suppression in Organic Transition
… soils, 2) to evaluate the ability of leguminous cover crops lablab (Dolichos lablab L.), soybean (Glycine max L.), sunn hemp (Crotalria juncea L.) and a sunn hemp and cowpea mixture (Vigna sinensis Endl.) to supply N and suppress weeds and, 3) to compare the effect on N availability and broccoli …

Using Thermal Units to Predict Biomass Accumulation and Total Nitrogen Uptake for Cover Crops in Arkansas
<p>Including cover crops in agricultural production systems is an important management practice. Cover cropping can improve soil health, increase plant-available nitrogen (N), provide surface residue to prevent erosional soil loss, increase water infiltration, and increase weed suppression. Cover …

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 …

Evaluation of Cover Crops, Conservation Tillage, and Nitrogen Management in Cotton Production in Southeastern Virginia
… hirsutum L.) to legume and small grain cover crop establishment, in-season nitrogen (N) rate, and fertilizer N placement was investigated in two experiments located in coastal plain Virginia and North Carolina. The first experiment examined 1) soil compaction and cotton yield response to …

Impacts of Spring-interseeded Cover Crops on Late-emerging Weed Suppression and Ground Cover in Corn (Zea mays L.) Production Systems
<p>Any alternative crop management strategy will only be adopted by growers if yield is not negatively impacted, fits within a current management practice, is easily implementable with minimal cost, or provides other beneficial features such as weed control or suppression. Corn production that …

Nutrient release from winter cover crops exposed to freeze-thaw events
Winter cover crops are widely promoted due to their numerous soil and water quality benefits. However, recent research has highlighted some concerns about the potential leaching of phosphorus (P) and nitrogen (N) from cover crop biomass after cycles of freezing and thawing. These freezing events …

A fresh soil health perspective: Soil health dynamics and improved measurement techniques
… practices such as reduced tillage and cover crops may require better understanding of the effect of these practices on soil health. The overall objective of this study was to quantify soil health dynamics due to conservation agriculture practices and address methodological gaps in terms …

Effect of cover crops on suppressing soilborne diseases of soybean and the association of green stem disorder with anthracnose, charcoal rot, and soil moisture
… to what would develop in a conducive soil. Some cover crops can foster the development of suppressive soils. Cover crops are more commonly used in the management of soilborne diseases of high value crops like fruits and vegetables and there is less information on their effectiveness in agronomic …
