Switchgrass Cultivar, Harvest Frequency, Fertilizer Source, and Irrigation Effects on Near-Surface Soil Properties in West-Central Arkansas
… frequency (1-cut and 2-cut systems per year), fertilizer source (poultry litter and commercial fertilizer), and irrigation management (irrigated and non-irrigated). Effects on soil properties were assessed on a Leadvale silt loam (fine-silty, siliceous, semiactive, thermic, Typic Fragiudult) at …

Field Measurements of Denitrification From Fertilizer Applied to Turfgrass
Denitrification and mass balance measurements of fertilizer N applied to turf was studied under field and greenhouse conditions. Highly enriched 15N-labeled KNO3 or urea was applied to replicated plots on a Flanagan silt loam soil under Kentucky bluegrass (Poa pratensis L.) or creeping bentrgrass …

The use of fertilizer nitrogen applications to increase productivity of soybean
… soybean [Glycine max (L.) Merr.] may require fertilizer nitrogen (N) to supplement biological N fixation. The objective of this study was to identify the best fertilizer source and the best plant growth stage for N applications to increase soybean yield using N fertilization. Trials were …

A multiple objective approach to evaluate economic and environmental impacts of agricultural management systems from a sustainable development perspective
… of sustainable development recognizes absolute resource scarcity, which is represented by the limited quantity of resources for inputs to economic systems; and is represented by the limits of the assimilative capacity of the environment for waste discharges. Advocates of the capacity of the …

Response of kikuyu grass (Pennisetum clandestinum) to irrigation with saline, sodic wastes and nitrogenous, manganiferous effluent
… waste has been identified as a possible nitrogen fertilizer source. Irrigation of the MMC waste over nearby kikuyu ( Pennisetum clandestinum) pastures could thus potentially solve a waste disposal problem as well as provide fertilization of the pastures, although the high manganese content of the …

Nitrogen and Sulfur Management in Soybean and Edamame Production in the Mid-Atlantic Coastal Plain
… have become more frequent in the U.S. due to fertilizer purity, emissions regulations, and higher yields. We completed 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 …

Applying the diagnosis and recommendation integrated system(DRIS) to Fraser fir Christmas trees
… (Pursh)Poir.] Christmas trees and prescribing fertilizers is not well understood. Agricultural researchers have established critical yield levels for agronomic crops that are objective measures of crop quality and have associated these yields with nutrient status; however, Christmas tree …

Impacts of Spring-interseeded Cover Crops on Late-emerging Weed Suppression and Ground Cover in Corn (Zea mays L.) Production Systems
… be used as a fall forage, act as a slow release fertilizer source the following year, and provide ground cover to reduce soil erosion. In South Dakota, cover crop establishment cannot occur after corn harvest, as the growing season is too short, cold, and often dry. Therefore, interseeding cover …
