  • Moisture Increase in Expansive Soils at Developed Sites

    The purpose of this paper is to provide information pertinent to post-development depth-of-moisture increase in expansive soils underlying developed sites. In southern California, the developments are generally accompanied by irrigation around buildings and other improvements. Local experience indicates that the major source of water that contributes to moisture variation in expansive soils is ...

  • Estimating the contribution of groundwater to rootzone soil moisture

    In the Huaibei Plain basin, China, soybean is a main crop. During the soybean growth period, rainfall can vary largely and depth to watertable can also vary largely. The amount of water supplied to the soybean rootzone by groundwater affects soybean growth and yield. Accurate simulation of groundwater contributions to soybean rootzone soil moisture (groundwater contribution) can be important for ...

  • Performance of a new capacitance soil moisture probe in a sandy soil

    Rapid population growth and increasing urban demand reduce the availability of water for agriculture in Florida. The water-holding capacity of sandy soils in the Central Florida Ridge area is very poor ( ...

  • The role of soil moisture accounting in estimation of soil evaporation and transpiration

    In this study, we explore how the differences in soil moisture accounting affect the estimation of actual soil evaporation (E) and transpiration (T). The main objective is, therefore, a comparative assessment of a vapor flux estimation method which has explicit soil moisture accounting, against a vapor flux estimation method that uses satellite observed soil moisture data. ...

  • Improved Water Supply Forecasts Using Soil Moisture Data

    HydraProbe used to improve water supply forecast from 3 SNOTEL sites in Idaho over traditional antecedent conditions using the principle component forecast model Much of the water in the Western United States used for irrigation, municipal supplies and hydro-electric production originates as winter snow pack at higher elevations. Since the early 1900s, the correlation between stream flow and the ...

  • Impacts of elemental S applied under various temperature and moisture regimes on pH and available P in acidic, neutral and alkaline soils

    We evaluated the effect of elemental S (S0) under three moisture (40, 60, 120% water-filled pore space, WFPS) and three temperature regimes (12, 24, 36°C) on changes in pH and available P (0.5 N NaHCO3-extractable P) concentrations in acidic (pH 4.9), neutral (pH 7.1) and alkaline (pH 10.2) soils. Repacked soil cores were incubated for 0, 14, 28 and 42 days. Application of S0 did not alter the ...

  • Utilisation of Municipal Solid Waste Compost as landfill cover soil for reducing greenhouse gas emission

    Municipal Solid Waste Compost (MSW-C) was introduced for improving landfill cover soil properties and enhancing methane oxidation. The landfill cover soil was irrigated with leachate for maintaining appropriate moisture content for methane oxidation reaction. It was found that MSW-C was an effective landfill cover material for landfill gas emission control exhibiting the highest Methane Oxidation ...

  • A Tale of Two Sites - Enhanced Bioremediation of Explosives Impacted Soils

    The problem with OE compounds in soil A variety of organic explosive (OE) compounds have been used for military, geological and industrial applications throughout North America, and in most industrialized nations. During their manufacture, formulation and storage, these compounds have migrated to the soil. Compounds such as 2,4,6-trinitrotoluene (TNT), hexahydro-1,3,5-trinitro-1,3,5-triazine ...


  • Quantifying soil surface photolysis under conditions simulating water movement in the field: A new laboratory test design

    Soil surface photolysis can be a significant dissipation pathway for agrochemicals under field conditions, although it is assumed that such degradation ceases once the agrochemical is transported away from the surface following rainfall/irrigation and subsequent drainage of soil pore water. However, as both downward and upward water movement occurs under field conditions, relatively mobile ...

  • Soils Characteristics of The Bassendean and Spearwood Sands of the Gnangara Mound (Western Australia) and their Controls On Recharge, Water Level Patterns and Solutes of The Superficial Aquifer

    The flow pathways of water in the soils of the Gnangara Mound are highly irregular and depend upon the moisture content, the repellency and preferential wettability potential of the soils. The occurrence of preferential flow is more evident in dry soils. As the soil wets during the rainy season, the water repellence and differential wettability decreases, the fingering and the preferential flow ...

  • Japanese Organics Recycling Association Formed

    Another backyard composting adage states that compost should have the feel of a wrung-out sponge — damp but not dripping wet. Actually, a wrung-out sponge may be on the dry side for composting, but the analogy does provide a great image for understanding the reasons for balancing moisture. Like a compost pile (or windrow or material in a vessel), a sponge is a solid mass containing an enormous ...

  • Phthalates: W.R. Grace - Dewey & Almy Chemical Division, New Jersey, USA

    Project Ex situ Treatment of Soils Impacted with Bis (2-ethylhexyl) phthalate Summary Soil impacted with bis (2-ethylhexyl) phthalate (BEHP) was treated ex situ in two covered land treatment cells containing approximately 450 yards of excavated soil. Concentrations of BEHP as high as 7,710 mg/kg, were reduced by 91.1% to 99.5% following 10 months of active ...


  • Monitoring the holy ground of FC Basel - Case Study

    The grass on athletic grounds, particularly in large stadiums, is not only an important concern for sports but also one of the largest cost drivers. Therefore, the monitoring and care of the grounds takes on special significance. PlantCare has installed a soil moisture monitoring system as part of the redesign of the entire playing field at St. Jakob-Park stadium in Basel. The system measures ...

  • Bioventing

    Introduction Bioventing is a promising new technology that stimulates the natural in situ biodegradation of any aerobically degradable compounds in soil by providing oxygen to existing soil microorganisms. In contrast to soil vapor vacuum extraction, bioventing uses low air flow rates to provide only enough oxygen to sustain microbial activity. Oxygen is most commonly supplied through direct air ...

  • Terramend, Heavy Oil & Diesel Fuel, Ontario, Canada

TERRAMEND™ effectively reduced contaminant concentrations to below the ...


  • Phtalates Confidential Client, Northeast, USA

    Project In Situ Treatment of Bis (2-ethylhexyl) phthalate (BEHP) Impacted Soil Summary DARAMEND® technology was selected as the remedial option of choice for the in situ treatment of 14,000 tons of BEHP impacted soil at a former plastics manufacturing facility in New Jersey. Surface soil (0-2 ft) was cleared of oversized debris and boulders (>6') using a ...


  • Land Treatment

    Introduction Land Treatment is a full-scale bioremediation technology in which contaminated soils, sediments, or sludges are turned over (i.e., tilled) and allowed to interact with the soil and climate at the site. The waste, soil, climate, and biological activity interact dynamically as a system to degrade, transform, and immobilize waste constitutes. Wastes are periodically tilled to aerate the ...

  • Scalewatcher Banishes Limescale In Gardens And Greenhouses

    In hard water areas, automated watering systems, sprinkler irrigation systems and greenhouse-misting systems clog with limescale, plant leaves develop white scale deposits and over-spray causes limescale build-up on greenhouse windows.
