Mine soil properties influencing white pine (Pinus atrobus L.) growth in Southwest Virginia
… used to identify minesoil, plant moisture, and foliar nutrient properties influencing white pine growth on reclaimed mine sites in southwest Virginia. PRESSAll (SAS Views, 1984) was used to determine relationships between soil properties and growth, soil properties and functional environmental …

Factors affecting loblolly pine growth following site preparation
… areas were randomly selected for analysis of foliar nutrients, soil nutrients, and competing vegetation. Herbaceous, woody shrub, and hardwood competition levels were not significantly different among site preparation treatment areas after four years. However, hardwood competition levels had …

Responses of two grass species to plant growth regulators, fertilizer N, chelated Fe, salinity and water stress
… creeping bentgrass (Agrostis palustris Huds.) to foliar applications of two plant growth regulators (PGR) and/or chelated Fe (Na Fe diethylene triamine pentaacetate). Environmental variables considered were N levels, soil moisture regimes, and saline irrigations. The two materials investigated for …

Adaptive Silviculture in an urban floodplain forest: exploring functional traits and soil responses for climate ready forests
… photosynthetic performance, water relations, and foliar nutrients of the individuals and communities in the experiment. In addition to exploring tree ecophysiology, we also measured soil moisture and temperature dynamics at multiple depths to assess whether the experimental treatments that vary in …

Applying the diagnosis and recommendation integrated system(DRIS) to Fraser fir Christmas trees
The process of diagnosing the foliar nutrient status of Fraser fir [Abies fraseri (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 …

Ecological site quality, site index, and height growth of white spruce stands in the sub-boreal spruce zone of British Columbia
… (Moench) Voss] height growth, vegetation, soil, foliar nutrient, and stem analysis data were obtained from 102 white spruce-dominated stands across a wide range of sites throughout the Sub-Boreal Spruce (SBS) biogeoclimatic zone of central British Columbia. The data were analyzed using the …

Growth and nutrient relations in black cottonwood in South-Coastal British Columbia
… and among site temporal and spatial variation of foliar nutrients, and spatial variation of soil nutrients to assess the sampling methods employed, and to provide background for the interpretation of nutrient-site index interactions. The study then examined relationships between the growth of …

Evaluation of Topsoil Substitutes for Restoration of Appalachian Hardwoods on Strip Mined Land
… americana, Q. rubra and microbial populations. Foliar nutrient analysis indicated that L. tulipifera was highly dependent on nutrient levels and was unable to grow well on any of the spoil types due to deficiencies. Inoculation with topsoil increased tree growth on the GUH spoil, and increased …

The effectiveness of actively accumulating dust in rejuvenating soils and ecosystems in a super-humid, high weathering and leaching environment, West Coast, South Island, New Zealand
… as an important rejuvenator by supplying nutrients and unweathered mineral material to ecosystems. While deposition rates have been regularly quantified for terrestrial environments in the past, the rejuvenating effect of dust on soils and terrestrial ecosystems and the accessional …
