Abstract:

Serpentine soils select for unique plant communities, often with sparse vegetation. Mycorrhizal fungi mediate the interaction between plants and soils, yet little is known about the mycorrhizal fungi of serpentine-tolerant plants. Ectomycorrhizas and hypogeous fungal sporocarps were sampled on paired serpentine and nonserpentine soils in southwestern Oregon. We hypothesized that conifers on serpentine soils would have fewer species of mycorrhizal fungi, a distinct assemblage of ectomycorrhizal fungi, and fewer hypogeous sporocarps with less species richness. Sporocarps were sampled and soil co

The Sumas River watershed, located in the intensive agricultural region of the Lower Fraser Valley of British Columbia (Canada), contains serpentine asbestos from a natural landslide. Serpentinic soils have a high Mg to Ca ratio that can affect soil fertility, including soil-solution P relations.

Abstract:

Metal hyperaccumulators are plants that store heavy metals or metalloids in their leaves, often to concentrations much higher than in the soil. Though most occur exclusively on metalliferous soils, some species are facultative, occurring on both metalliferous and nonmetalliferous soils. Psychotria grandis Sw.(Rubiaceae) occurs from Central America through the Caribbean on many soil types, and hyperaccumulates nickel (Ni) on serpentine soils in several localities. In this study, four Puerto Rican populations of P. grandis – two from serpentine soil and two from non-serpentine soil – were examin

AbstractSuccessful colonization of newly introduced species is driven by a multitude of factors and is highly dependent on the species. It has long been hypothesized that preadaptation and postestablishment natural selection of introduced species can facilitate their invasion; however, to date, limited research has been dedicated to these theories. In addition, although the correlation between establishment of invasive species and disturbance has been noted and widely studied, the susceptibility of undisturbed habitats to invasion remains unclear.

We hypothesised that the structure and foliage elements of the eucalypt forests could be used as biological indicators of the severity of the serpentine soils.

Abstract:

Serpentine soils are a stressful growing environment for plants, largely due to nutrient deficiencies and high concentrations of toxic heavy metals (e.g., Ni). Plants have evolved various adaptations for tolerating these extreme environments, including metal hyperaccumulation into above-ground tissues. However, the adaptive significance of metal hyperaccumulation is a topic of debate, with several non-mutually-exclusive hypotheses under study. For example, the inadvertent uptake hypothesis (IUH) states that heavy metal accumulation is a consequence of an efficient nutrient-scavenging mechanism

Abstract:

Easily dissolved fertilizers release nutrient in excess amount to be assimilated by plant roots. Some portions these fertilizers leach out from the root zone and adversely impact the environment. Controlled-release fertilizers are more favorable to reduce fertilizer loss, labor cost, and environmental impact. Urea-formaldehyde (UF) was synthesized by polymerization of urea and 40% formaldehyde solution using H3PO4 as a catalyst. Three mole ratios of urea:formaldehyde, namely, 1.0:1.0, 1.5:1.0 and 2.0:1.0 were synthesized. Mineralization of the UF was conducted using eight different mixtures, f

Abstract:

A description of mobile Ni contents in various subtypes of calcareous black soils from the area of the mountain massif of Rajac, is given in the present paper. A hundred soil samples were analysed in all, originating from four subtypes of calcareous black soil (organogenic, organo-mineral, brownized and loessivized black soils). The extraction of mobile Ni was carried out with 1.0 N HCl and its content was determined by atomic absorption spectrophotometry. The obtained results indicate that mobile Ni content in the investigated soils varies within a wide range, from 5.0 to 251.3 mg/kg that it

Abstract:

Abstract The aim of this study was to assess the condition of soil after serpentine fertilisation by determining the activity of phosphatase and some physicochemical properties of soil. The study was conducted in southern Poland in the Wisła Forest District (49°8’12.92N 18°58’56.36E). The following variants: C - control - no fertiliser; S - ground serpentinite; SN - serpentinite + nitrogen; SP - ground serpentinite + P; SNP - ground serpentinite + NP; SNPK - ground serpentinite + NP (as above) + K. Fertilisation of serpentinite stimulates the activity of phosphatase in soil under spruce stands
