The successful functioning of a bioretention system depends on the use of suitable soil media. Predictive computer modelling of a bioretention system (e.g. using the MUSIC software) assumes specific characteristics of the soil media to achieve a certain level of stormwater treatment. Therefore, the soil media used in the construction of a bioretention system must exhibit the required characteri...

An experiment was conducted to study the effects of different soil media on seed germination and seedling growth of peach during 2001 and 2002 in Orakzai Agency. Different soil media alone and in combination used for seed germination of peach were Farm Yard Manure, Saw dust, Canal silt, FYM + Sawdust, FYM + Canal silt, Sawdust + Silt and FYM + Sawdust +Silt. Different media showed non significa...

Recent federal and state regulations require storm water runoff to be treated by structural controls in ultra-urban development. Several practices have been used in North Carolina; however, a less common storm water management practice is the greenroof. Two extensive greenroofs have been constructed within the Neuse River Basin of North Carolina. Each greenroof retained approximately 60% of the...

Study on corrosion propensity of welded mild steelbar in soil media around the coastal area of University of Lagos has been carried out using gravimetric method. Six (6) samples each for welded and unwelded mild steels were cut, their initial weights were recorded and buried in two selected soil. The weight losses of these coupons were measured at regular intervals for a period of six months (1...

Interrelationships between pyrogenic polycyclic aromatic hydrocarbons (PAHs) were assessed in air, soil, water, sediment, and tree leaves by using multi-media monitoring data. Concurrent concentration measurements were taken bimonthly for a year for the multi-media at urban and suburban sites. PAH level correlations between air and other media were observed at the urban site but were less clear...

composting of organic agricultural wastes is a sustainable method for recycling of the wastes. for determining the effects of tea waste compost (twc) and tree bark compost (tbc) on growing media and some quantity and quality of greenhouse lettuce cv. grate lake 118 this experiment was carried out based on a completely randomized design of four replications. the treatments were different mixture...

Studies were undertaken to determine the genetic needs for the survival of Pseudomonas fluorescens Pf0-1, a gram-negative soil bacterium potentially important for biocontrol and bioremediation, in soil. In vivo expression technology (IVET) identified 22 genes with elevated expression in soil relative to laboratory media. Soil-induced sequences included genes with probable functions of nutrient ...

UNLABELLED PREMISE OF THE STUDY Effects of drought stress and media type interactions on growth of Pinus ponderosa var. scopulorum germinants were investigated. • METHODS AND RESULTS Soil properties and growth responses under drought were compared across four growth media types: two native soils (dolomitic limestone and granite), a soil-less industry standard conifer medium, and a custom-m...

We report the results of a research carried out in Turkey in 2004 to determine the effectiveness of different levels of pumice amendments to soil using strawberry plants. Two grades (2-4 mm and 4-8 mm) of pumice were added to soil and three amendment levels (15%, 30% and 45% by volume) were applied. Finally 6 different growing media types were formulated. The amount of moisture retained at diff...
