Vineyard soil matters: exploring the influence of soil physical and chemical properties on Eastern U.S. grape production
The relationship between soil and wine quality has been recognized for generations but has had limited scientific validation. Vineyard soils in the eastern United States are largely unstudied although proper site selection and good soil management have the potential to improve fruit composition for …

The Effects of Prescribed Burning on Soil Water Infiltration Rates and Other Select Soil Physical and Chemical Properties in East Texas
… focused on whether prescribed burning affects soil physical and chemical properties, especially water infiltration, in Western Gulf Coast forests. Soil water infiltration rates were measured 1) pre-burn (before the fire), 2) post-burn (one month after the fire), and 3) at vegetation green-up …

Effect of Scrubber Sludge and Fly Ash on Soil Properties and Crop Growth
… produce large quantities of scrubber sludge and fly ash that must be disposed of responsibly to avoid environmental degradation. Field and greenhouse studies were conducted to determine the effect of land application of these waste products on soil physical and chemical properties and on corn …

Cotton Yield as Related to Selected Physical and Chemical Properties of Soils of the Coastal Plain of Virginia and North Carolina
… with indeterminant growth habit. In 1995, 42,500 and 300,000 hectares were grown in Virginia and North Carolina, respectively. Soil physical and chemical properties may limit cotton yields. The objective of this study was to; 1) determine influences of soil physical and chemical properties on …

Determination of fertility rating (FR) in the 3-PG model for loblolly pine (Pinus taeda L.) plantations in the southeastern United States
Soil fertility is an important component of forest ecosystem, yet evaluating soil fertility remains one of the least understood aspects of forest science. Phytocentric and geocenctric approaches were used to assess soil fertility in loblolly pine plantations throughout their geographic range in the …

Quality Soil Management in Illinois Using Winter Cover Crops
… of information regarding the effects of WCC on soil productivity. The objective of this study was to assess the effects of different crop rotations on several soil physical and chemical properties. Three crop sequences including WCC were compared with winter fallowing (control) in a corn (Zea …

Relationships Among Soil Properties and Soil CO2 Efflux in a Loblolly Pine-Switchgrass Intercropped System
The components of soil CO2 efflux are affected by many soil properties including temperature, moisture, microbial abundance and activity, and other soil physical and chemical properties. Changes in these factors can result in high spatial and temporal variability of total soil CO2 efflux. Low …

Earthworms in the Urban Environment: Can Population Augmentation Improve Urban Soil Properties?
… forests perform essential ecological functions, and their performance is dependent on soil quality, which is often degraded by human activity. Because earthworms play a key role in soil health, augmenting earthworm populations in urban soils may improve tree performance. However, we know very …

Effects of Black Walnut and Honey Locust on Forage Growth, Soil Water, and Soil Quality Indicators
… was to determine the interactions between forage and tree components of a silvopasture system. Two studies were performed on adjacent sites established in 1995 at Virginia Tech's Kentland Research Farm. The objectives of the studies were to: 1. Determine the influence of honey locust and black …

Long-term n fertilization affects soil bacterial communities in agronomic fields
Soil microbial communities influence plant productivity, chemistry and structure of soil and nutrient cycling. In turn, long-term nitrogen fertilization changes soil physical and chemical properties and thus influences soil microbiomes. In-depth understanding of the long-term nitrogen fertilization …

The effects of winter cover crops and soil compaction treatments on soil properties and soybean production in Illinois
… a tool to alleviate compaction while improving soil properties. However, WCC have also been reported to have detrimental effects on the following crop. Our goals in this study were twofold: i) to evaluate the short-term ability of radish and companion cover crops to alleviate induced soil …

Soil conditions and early crop growth after repeated manure applications
Development of the swine and cattle industries has led to an increase of manure application to agricultural lands in Saskatchewan. Studies have been conducted to determine the nutrient benefits of swine manure application. However, a need was also identified for information on the effects of manure …

Genetics by Nutrient Availability Interactions on Short-term Carbon Pools and Fluxes in Young Pinus taeda Plantations
… of this research was to determine how genetics and nutrient availability influence C cycling in intensively managed southern pine forests. This work consisted of a two year field and a complimentary one year greenhouse study each split into above- and below-ground pools and fluxes. Both the …

The Maya Footprint: Soil Resources of Chunchucmil, Yucatan, Mexico
… Yucatán are constrained by climate, thin soils, and low fertility. Despite this, the ancient Maya city of Chunchucmil Yucatán, Mexico, boasted an immense, dense, and wealthy population during the Middle Classic period (ca A.D. 400-700). Soil physical and chemical properties were explored …

Selectivity and soil behavior of chlorsulfuron
Response of barley (<i>Hordeum vulgare</i> L.) and wheat (<i>Triticum aestivum</i> L.) to root-applied chlorsulfuron (2-chloro N-[[(4-methoxy-6-methyl-1,3,5-triazin-2-yl) amino] carbonyl] benzenesulfonamide), a herbicide for use in small grains, was investigated. The results showed that, although …
