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 …

Effects of Excessive Soil Phosphorus Accumulation on Loblolly Pine (Pinus taeda L.) Seedlings
… biomass (above and below ground), survivability, foliar nutrient content, and ground needle color Munsell color transformation comparison. Growth trends in the study were positive for growth relationship to P treatment level increase. However, at the end of the first growing season seedlings …

Two Year Survival and Growth of Loblolly Pine Seedlings from Two Texas Seed Sources on Lignite Minesoils
… during the second growing season. Standard foliar analyses were conducted at the end of the second growing season. East Texas seedlings grew more in height and root-collar diameter, and had higher survival percentages than Lost Pines. No growth response from treatment with P. tinctorius was …

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 …

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 …

Survival and growth of pine seedlings on strip-mined sites
… growth, ectomycorrhizal colonization, and foliar nutrient levels of container-grown white (Pinus strobus L.), loblolly (P. taeda L.), and Virginia pine (P. virginiana Mill.) seedlings were studied on a recontoured and a fiat bench strip-mine site in Southwestern Virginia. One-half of the …

Water and Nutrient Reuse within Closed Hydroponic Systems
… research exists on the maintenance of individual nutrient balance within the nutrient solutions of closed hydroponic systems and how this maintenance may result in reductions in water and nutrient consumption. In this study, a nutrient solution management procedure was developed to maintain …

The effect of soil nutrient availability on resource allocation in tropical tree species
… functional variation among tropical trees in nutrient use, and the implications of this functional diversity of tropical forest nutrient and carbon cycling. Through a comparison forest litterfall patterns along a natural fertility gradient and experimental nutrient addition, I show that …

Effects of different canopy tree species on belowground biogeochemistry in a wet lowland tropical forest
… Interspecies differences in both the demand for nutrients and in foliar nutrient concentrations could drive differences in litter chemistry that affect both pools and fluxes of belowground resources. Yet, our understanding of the effects of aboveground biogeochemical heterogeneity on belowground …

Innovative foliar micronutrient sources in high-yielding corn environments
"Under high-yield conditions, adequate nutrient availability often limits corn (Zea mays L.) growth and productivity. Nitrogen (N), potassium (K), and boron (B) accumulation mainly occurs before flowering compared to the uptake of phosphorus (P), sulfur (S), and zinc (Zn), which primarily occurs …

Nitrogen dynamics after site preparation in three loblolly pine plantations on the Virginia Piedmont
… for the s-o, and S,R,D areas, respectively. Pine foliar nutrient concentrations determined after the second and third growing seasons provided no evidence of existing or impending nutrient deficiencies. These results show that short-term pine nutrition and growth were not adversely affected by …
