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 system to enhance soil conservation, reduce labor requirements, and decrease diesel fuel use compared to traditional organic production. This system is based on the use of(More)
Organic producers in the mid-Atlantic region of the USA are interested in reducing tillage, labor and time requirements for grain production. Cover crop-based, organic rotational no-till grain production is one approach to accomplish these goals. This approach is becoming more viable with advancements in a system for planting crops into cover crop residue(More)
Rye (Secale cereale L.) residue is known to suppress weeds in agronomic environments and to produce benzoxazinoid (BX) compounds which are phytotoxic. Experiments were conducted to determine the duration of indicator plant inhibition and BX soil concentrations in response to field incorporated or surface rye residue. Surface rye residue was highly(More)
I n the Mid-Atlantic region of the United States, forage radish winter cover crops planted before 1 September suppress winter annual weeds from fall through early April (Lawley et al., 2011). This weed suppression may be used by farmers to provide pre-plant weed control for a subsequent crop while taking advantage of the soil quality and nutrient benefits(More)
The transport of runoff with high copper concentrations and sediment loads into adjacent surface waters can have adverse effects on nontarget organisms as a result of increased turbidity and degraded water quality. Runoff from vegetable production utilizing polyethylene mulch can contain up to 35% of applied copper, a widely used fungicide/bactericide that(More)
Metabolomics provides a view of endogenous metabolic patterns not only during plant growth, development and senescence but also in response to genetic events, environment and disease. The effects of the field environment on plant hormone-specific metabolite profiles are largely unknown. Few studies have analyzed useful phenotypes generated by introducing(More)
Above: Corn growing in a no-tillage system plot as part of the long-term Sustainable Agriculture Demonstration Project at Beltsville, Maryland. The high residue cover is typical of long-term no-tillage crop production in the mid-Atlantic area. N o-tillage cropping systems are known to provide many benefits to soils that can enhance production of grain(More)
