Response of corn to manganese application on Atlantic coastal plain soils
… Mn, Mn deficiencies in corn were suspected on soils where Mn applications had previously increased soybean seed yields. Five experiments were conducted in farmer's fields to evaluate the response of corn to Mn applications. Three band Mn and two broadcast Mn studies were conducted in five field …

Soil mineralogy of an upper coastal plain landscape in Virginia
… for its proposed operation in the Upper Coastal Plain of Virginia due to the high clay content of the deposit. The original intent of this study was to identify the mineralogy present in the proposed mining area and to determine similarities and differences among sampled pedons. …

Effects of Biosolids on Carbon Sequestration and Nitrogen Cycling
… (mainly N and P) and improve organic matter in soils, but the effects of biosolids on C sequestration and N cycling in the Mid-Atlantic region is not well understood. The objectives were: 1) to investigate soil C sequestration at sites with a long-term history of biosolids either in repeated …

Biodegradability of dicamba and 2,4-D in riparian wetland soils
A general review of soils in Virginia counties bordering the Chesapeake Bay reveals that coastal plain soils, especially those most agriculturally productive, are dominantly sandy texture in the subsurface horizon, and have shallow water tables. Considering the high amounts of pesticides used in …

Manganese in Virginia soils and correction of manganese deficiency in soybeans (Glycine max L.)
… to provide basic information on Mn in Virginia soils and to evaluate rates and methods of Mn application to correct Mn deficiency in soybeans. Soil profile samples were analyzed from catenas representing the Appalachian, Piedmont, and Coastal Plain regions. The exchangeable, easily reducible, …

Biodegradation of tertiary butyl alcohol by an introduced Pseudomonas sp. in subsurface soil microcosms
… competed with the Pseudomonas sp. in both soils. A 1.0 mM molybdate amendment stimulated TBA degradation by the indigenous microflora but reduced the rate of TBA degradation by Pseudomonas sp., VT100, in subsurface soil microcosms. A TBA-degrading Alcaligenes sp. was isolated from the …

Soil-Specific, Late-Season Nitrogen and Potassium Applications to Increase Corn Yields in the Mid-Atlantic Coastal Plain
… (N) and potassium (K) availability on sandy coastal plain soils when soil moisture is adequate for high yields. This study evaluated irrigated corn grain yield response to late-season (just prior to tassel) N and K fertilizer applications, and enabled the proposal of a method to predict …

Tillage System Effects On Upland Cotton Yield and Development In Virginia
… agronomic benefits for cotton production in the coastal plain soils of Virginia was the basis for this research. Strip-tillage was evaluated from 2015-2016 on-farm to determine the effects of annual and biennial treatments on plant growth and lint yield, as well as measuring the impacts on soil …

Nutrient availability in mineral sand tailings amended with yard waste compost and wood ash
Mine tailings result from surface mining coastal plain soils and sediments and are redeposited in a slurry form to the mined area. Mine tailing contains a low amount of organic matter, a low pH, and a high P fixation capacity. This research was carried out in the Atlantic Coastal Plain region to …

Phosphorus Losses in Runoff from Virginia Soils
… Nine soil types from the Virginia Piedmont, Coastal Plain, and Ridge and Valley were collected and used in a rainfall simulation study. Phosphorus retention among separated clay fractions and whole soils were related to Al bearing minerals such as hydroxy-interlayered vermiculite (HIV), …

Nitrogen and Sulfur Management in Soybean and Edamame Production in the Mid-Atlantic Coastal Plain
… a study for soybean grown in sandy loam soils in the mid-Atlantic coastal plain system to determine proper S fertilizer rate and application timing. Yields ranged from 1,236-4,051 kg ha-1. Neither S rate nor application timing influenced yield. S treatments increased methionine …

Greenhouse evaluation of potassium application on selected soil and plant properties utilizing four Virginia ultisols
… of corn (<i>Zea mays</i> L.) were grown on four Coastal Plain soils in a greenhouse study to determine the effects of increasing rates of Kon corn growth, elemental composition of corn tissue and soil nutrient levels. Plant height and production of dry matter were measured to determine the effect …

Relationship of selected parameters to farm sale values in three Virginia counties
… over a five year period in two adjacent Coastal Plain counties and 84 farm sales in a Piedmont county were studied in an effort to identify and analyze factors affecting sale price. The effect of soil productivity and landscape characteristics were of particular interest in this study. …

Effect of Poultry Litter-Yard Waste Compost Application on Phosphorus Availability in Diverse Soils
… isotherms were used in this research to select soils with relatively high P fixation capacities. Phosphorus sorption maximum for soils evaluated were as follows: 304 and 449 micrograms of P per gram for A horizon Coastal Plain soils (Series: Kempsville and Myatt, respectively); 487 micrograms of …

Novel Coated Fertilizers as Multi-Nutrient Sources for Soybeans and Tomatoes
Virginia's Coastal Plain region contains the majority of the state's agricultural production despite having low nutrient soils. The soils in this region are predominantly coarse-textured acid soils with low cation exchange capacities (CEC) (< 3 cmol kg-1) and thus frequently exhibit nutrient …

Cultivating Sustainability: Analyzing Soil Health Dynamics and Economics of Cover Crops in the Mid-Atlantic
… performance, and economic returns in Virginia's Coastal Plain. Nine years after integrating NT practices and CCs, improvements in soil physical and chemical properties were observed, including a 22% to 65% increase in soil organic matter (SOM) in the top 5 cm, a 4% reduction in bulk density, and …

Poultry Litter Ash as an Alternative Fertilizer Source for Corn
… separate P, K and N corn studies across Virginia coastal plain soils to determine fertilizer effects on corn plant parameters [(most mature leaf (V6), corn ear leaf (R1), and grain (R6)]. Poultry litter P treatments, averaged over rate, recorded highest yield in both years. At eight of nine field …
