Off‐road vehicle (ORV) use is an increasingly popular form of outdoor recreation throughout the United States. This form of motorized recreation, however, can sometimes lead to serious erosion of trail running surfaces, with resulting export of sediment into forested ecosystems causing environmental degradation. This project was conducted to determine the feasibility of using two types of soil ...

SUMMARY The impact of a Pseudomonas fluorescens strain, genetically modified for kanamycin resistance and lactose utilisation (the GMM), could be enhanced by soil amendment with lactose and kanamycin. Lactose addition decreased the shoot to root ratio of pea, and both soil amendments increased the populations of total culturable bacteria and the inoculated GMM. Only kanamycin perturbed the bact...

Amending contaminated soils with organic wastes can influence trace element mobility and toxicity. Soluble concentrations of metals and arsenic were measured in pore water and aqueous soil extracts following the amendment of a heavily contaminated mine soil with compost and biochar (10% v:v) in a pot experiment. Speciation modelling and toxicity assays (Vibrio fischeri luminescence inhibition a...

Composting has emerged as a valuable route for the disposal of urban waste, with the prospect of applying composts on arable fields as organic amendments. Proper management of urban waste composts (UWCs) requires a capacity to predict their effects on carbon and nitrogen dynamics in the field, an issue in which simulation models are expected to play a prominent role. However, the parameterizati...

Recently problems relating to environmental pollution and the need to protect and preserve the environment from further deterioration has drawn increasing research attention. The goal of any remediation based on soil amendments is to achieve maximum reduction in the bioavailability of heavy metals by immobilization in soils. Modern remediation approaches increasingly focus on in situ environmen...

To reduce Cd phytoavailability in calcareous soils, the effects of soil amendments of red mud, rape straw, and corn straw in combination with zinc fertilization on Cd extractability and phytoavailability to spinach, tomato, Chinese cabbage and radish were investigated in a calcareous soil with added Cd at 1.5 mg kg-1. The results showed that water soluble and exchangeable Cd in soils was signif...

The growth and biomass production by willow (Salix viminalis L.) was studied in lysimeters containing Oxford clay landfill cap soil with different amendments, bulk densities and watering regimes. Three years from planting, stem biomass in well-watered plants was least (0.28 kg plant(-1)) with high bulk density soil (1480 kg m(-3)) and no nutritional amendment but was increased 10-fold (2.53 kg ...

the aim of this study was to evaluate the effect of bio-fertilizers on growth and development of plants in pots containing (v) vermicompost and (m) cow manure: (soil amendments) and (s) garden soil separately and in combination. in the first experiment, treatments included s (control), sm (soil + 15%m + 0%v), smv10 (soil + 15%m + 10%v), and smv20 (soil + 15%m + 20%v) by dry weight (w/w). in the...

The quantification of nitrogen (N) supplying capacity of organic amendments applied to a soil is of immense importance to examine synchronization, N release capacity, and fertilizer values of these added materials. The aims of the present study was to determine the potential N mineralization and subsequent nitrification of separate and combined use of poultry manure (PM), wheat straw residues (...
