Impacts of timber harvesting on soil physical properties in wetlands
… Hurricane Hugo in the fall of 1989. High soil moisture conditions during salvage operations resulted in soil compaction and deep rutting (puddling) on primary skid trails. Two studies were established to assess the effects of trafficking on soil physical properties and hydrologic …

The Influence of Plant Diversity on Soil Physical Properties in Grasslands.
… virtually nothing is known about the response of soil physical properties to plant biodiversity change, which represents a serious gap in our knowledge given the key role soil physical structure has in providing an essential medium for plant growth; microbial activity; carbon storage; nutrient …

On-the-go soil physical properties characterization using acoustic emission detection
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2021-05-01

Corn root growth and distribution as influenced by soil physical properties
… in the field and by observing the influence of soil physical stresses on corn seedling root growth in controlled environments. The field soil was Groseclose silt loam (clayey, mixed, mesic Typic Hapludult). Groseclose A horizon material was used for the growth chamber experiments where corn was …

Effects of severe cattle treading on soil physical properties and pasture productivity
… one of the severest forms of treading damage to soil, and occurs when soil is grazed while near saturation, resulting in plastic and liquid soil deformation. The research objectives were to quantify effects from one-off treading events, at different severities, on soil physical properties and …

Soil Structure and Organic Matter Dynamics: Influence of Tillage and Soil Physical Properties
Understanding structural controls over soil organic carbon (SOC) dynamics might improve our ability to predict inconsistent tillage influences on SOC sequestration. This research investigated the influence of soil structure on SOC mineralization and SOC fraction dynamics. A laboratory incubation …

A wetland trafficability hazard index based on soil physical properties and site hydrology evaluations
… activities are performed on wetland soils highly susceptible to rutting and puddling. Potential decreases in pine productivity have been connected with increased soil strength and decreased aeration that are commonly remnants of site disturbances associated with wet-weather …

Tillage effects on soil physical properties, weed seed distribution in soil and shifts in species
… a study on how long-term tillage systems affect soil strength, bulk density, soil water characteristics, weed seed distribution in soil, and shifts in species. The experiment included a corn-soybean rotation with both crop grown each year. For this study, only the corn crop was considered. The …

Slash Mulching and Incorporation as Mechanical Site Preparation for Pine Plantation Establishment and Subsequent Effects on Soil Moisture and Site Hydrology
… activities may have adverse effects on soil physical properties, site hydrology, and overall site productivity. Substantial quantities of wood residues are often left on these sites by timber harvesting operations, and it was hypothesized that the incorporation of this slash into the …

Topdressing and aerification programs on creeping bentgrass fairways
… effect that these two cultural practices have on soil physical properties have not been fully assessed. The first objective of this study was to determine the optimum timing of topdressing and aerification for golf course fairways. The second objective was to determine if varying schedules of …

Rehabilitation of Severely Compacted Urban Soil to Improve Tree Establishment and Growth
… development restricts tree growth by damaging soil structure and removing organic matter. Mechanical loosening and organic amendment may improve soil physical properties and tree establishment and growth. Effects of typical post-construction practice and improved methods of soil restoration on …

Assessment of Site and Soil Characteristics of Rill Erosion Following the Lockheed Fire in the Little Creek Watershed, Swanton Pacific Ranch
… determine how the impacts of the fire affect the soil physical properties where rill erosion occurred. In order to address this goal, the soil physical properties were characterized on two hillslopes influenced by three different types of parent material: Santa Cruz mudstone, Santa Margarita …

Disturbance, Functional Diversity and Ecosystem Processes: Does Species Identity Matter?
… on vegetation dynamics, physicochemical soil properties, and ecosystem processes. Additionally, plant functional diversity has been suggested as the key to ecosystem processes such as productivity and nutrient dynamics. I investigated how disturbance and functional composition both singly …

Variabilidade espacial de atributos físicos em latossolo amarelo de área experimental
Knowledge of the variability of soil properties constitutes an important tool that we can employ a more appropriate management. The objective of this study was to investigate the spatial variability of soil physical properties in the area of production under experimental Oxisol. The study was …

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 …

Investigation of electro-mechanical properties of soil materials
The variations of soil physical properties throughout the world play a significant role in agricultural production and understanding where these variations occur may lead to enhancement of crop production and soil protection. Methods used to determine these properties today present a significant …

Integrating Above and Belowground Components of Biodiversity across Spatial Scales: The Role of Host Plants in the Distribution of Arbuscular Mycorrhizal Fungi
… extra-radical mycelium extends throughout the soil and absorbs nutrients that are transferred to their host plant in exchange for a purely phytogenic carbon supply. Due to their ubiquity and their functional importance, they are the subject of much research into their community ecology, yet …
