Studies of peat swamps in Sarawak with particular reference to soil-forest relationships and development of dome-shaped structures
… rate and water-table fluctuation. Almost all the nutrient elements show a surface concentration indicating the effect of the standing vegetation. Below the topsoil, the degree of decomposition and the levels of most nutrient elements show a decreasing trend down the profile. The trend is reversed …

Estimates of above-ground phytomass and nutrients in the understory vegetation in an Appalachian oak forest in Virginia
… and shrub stratum to above-ground phytomass and nutrients (N, P, K, Mg and Ca) in four different vegetation types in an Appalachian oak forest in southwestern Virginia. The study area is located at midslope on the southeast aspect of Potts Mountain in four non-contiguous compartments which are to …

Influence of plant growth regulators on turfgrass polar lipid composition, tolerance to drought and salinity stresses, and nutrient efficiency
… A higher uptake efficiency of most essential elements was found in PPC and FSE-treated Kentucky bluegrass (Poa pratensis L.) than in the control (without PGR treatments). This effect was greater at lower than at higher fertilization levels. The utilization efficiency of some major nutrient …

Oxalic acid production by the ectomycorrhizal fungus Hebeloma westraliensis and its role in the nutrient acquisition and growth of Eucalyptus diversicolor in calcareous soil
… the solution concentrations of both of these nutrient elements, due partly to sequestration of these elements in fungal and plant tissues. Plant tissue P concentration was decreased and tissue Ca concentration increased in the calcareous systems. Mycorrhization increased the concentrations of …

The Neoproterozoic São Francisco Basin, central Brazil: tectonic evolution, paleoclimate, and mineral systems
… global changes in the biogeochemical cycling of nutrient elements. The basal Macaúbas Group (ca. 950-650 Ma), composed of rift-related sediments, accumulated during breakup of the supercontinent Rodinia. Deposition was punctuated by globally correlative Sturtian glacial deposits (ca. 717-660 Ma). …

Application of silicon to improve yield and quality of potatoes (Solanum Tuberrosum L.)
… Recent studies have shown that non essential nutrients such as Silicon (Si) are beneficial to plants in terms of yield, protection from fungal diseases and improved uptake of phosphorus. Since very little research has focused on the role of Si in improving potato production, three glasshouse …

Conyza bonariensis glyphosate tolerance as affected by origin temperature and growth stage
… with foliar manganese and other foliar-applied nutrient elements, in particular cations such as Mn2+, Zn2+, Fe2+, etc, are known to decrease glyphosate efficacy. The aim of the present study is to determine if growth stage has an influence on glyphosate tolerance in C. bonariensis, if highly …

Investigating the role of nonantibiotic chemical contaminants in the evolution of antibiotic resistance
… temperature, pH, salinity, and different nutrient elements would affect the growth of resistant and susceptible bacteria. The results showed that several physicochemical parameters (e.g., pH, KCl, Fe-limited condition) could affect the relative fitness of susceptible bacteria and resistant …
