  • `Standards are desperately needed for plastic and pesticide contamination in soil´

    In addition to plastic in the oceans, plastic contamination in arable land throughout Europe and other parts of the world is a growing problem. No standards exist for these types of soil pollutants, nor for pesticide residues or their degradation products. For this reason, Professor Violette Geissen is calling for standards to be implemented. On 15 June, Geissen will deliver her inaugural address ...

  • Improving Groundwater with Chemical Treatments

    Groundwater contributes to the health and well-being of a natural environment in the area and those systems connected to it. There are times that contaminants create an imbalance in groundwater, and a groundwater treatment system needs to be applied. Here are some chemical treatments that work to help ...

  • Blending and Bagging at Sungro Production Facility

    What’s In The Bag? A recent visit by FibreDust to the Sun Gro Horticulture blending facility, located just outside of Orlando, Florida, gave a glimpse into the business of soilless media and blending. The facility had a massive mixing and bagging line with 14 huge hoppers that added essential ingredients to soilless blends. Numerous tidy bunkers of various additives were scattered ...

  • U.S. Farm-Raised Finfish and Shellfish

    Seafood has long been recognized as an important component of a healthy diet. Seafood contains high quality, complete protein and an important array of nutrients, while it is low in calories, cholesterol, and saturated fats. The health benefits of omega-3 fatty acids found primarily in fish have been clearly documented. U.S. farm-raised seafood is an important center of the plate choice that can ...

  • Seasonality & optimal calf care

    Changing seasons, and challenging seasonal extremes (cold, heat and humidity), add extra challenges for a young calf and the caregivers management must be dynamic in order to provide optimal care. A reminder of calf needs should be outlined, especially with the primary calf worker(s). Topics of focus should involve: Optimal nutrition, the importance of access to clean water, clean and dry resting ...

  • Soil water thermal liquid diffusivity

    The background of the thermal liquid diffusivity (TLD) concept was reviewed. Application of TLD to matric-head-based equations for water flow when a thermal gradient is present have been contradictory to the original development by Philip and de Vries (PdV). Beginning from Darcy's law for liquid water transport and Fick's law for water vapor transport was the foundational and well-known approach ...

  • Bimodal and multimodal descriptions of soil-water characteristic curves for structural soils

    In the last decades several approaches have been developed to describe bimodal or multimodal soil-water characteristic curves (SWCCs). Unfortunately, most of these models were derived empirically. In the presented study, physically based bimodal and multimodal SWCC functions have been developed for structural soils. The model involved two or more continual pore series; the probability density ...

  • Soil water content and soil disaggregation by disking affects PM10 emissions

    Row crop agriculture in California's San Joaquin Valley is a major contributor of particulate matter <10 µm in aerodynamic diameter (PM10). The California Air Resources Board uses fixed PM10 emission values for various tillage operations to monitor and design attainment strategies. However, fixed emission values do not reflect emissions produced by a single implement operating under different ...

  • Measurement of Steady-State Soil Water Flux across a Soil Horizon Interface

    Soil horizon interfaces have been shown to be focal points for localized, three-dimensional redistribution of water and solutes in field soils. Therefore, understanding of the physics of water flow and transport in layered soils requires experimental observations of the magnitude and variability of local soil water flux under a variety of well-defined boundary conditions. We developed a time ...

  • Water Quality, Soil and Managing Irrigation of Crops

    The book entitled Water Quality, Soil and Managing Irrigation of Crops comprises three sections, specifically: Reuse Water Quality, Soil and Pollution which comprises five technical chapters, Managing Irrigation of Crops with four, and Examples of Irrigation Systems three technical chapters, all presented by the respective authors in their own fields of expertise. This text should be of interest ...

  • Soil water repellency development in amended sand rootzones

    Particulate organic matter (OM) and surface area–limited sands are associated with soil water repellency (SWR) in turfgrass systems. The increasing ubiquity of amended sand rootzones warrants investigation of factors contributing to SWR. Our objective was to identify how amendment type and/or inclusion rate affect rootzone SWR over a range of irrigation regimes. A U.S. Golf Association–specified ...

  • Effects of estimating soil hydraulic properties and root growth factor on soil water balance and crop production

    Accurate simulation of plant growth depends not only on plant parameters, but also on soil parameters. Although there is uncertainty in measured soil parameters and root distributions, their effects on simulated plant growth have been much less studied. This study evaluates the simulated responses of six crops, wheat (Triticum aestivum L.), maize (Zea mays L.), barley (Hordeum vulgare L.), ...

  • Effects on macronutrient contents in soil-plant irrigated with different quality waters and wastewaters

    The goals of this research were focused on investigating the effects of irrigation with untreated wastewater, ozone-enhanced primary treated wastewaters (O3EPTW), tap water and tap water + fertilizer on the macronutrient content in soil and plant tissues. The effect on plant development was evaluated by growing Lactuca sativa in soils irrigated with these different quality ...

  • The impact of climate change and soil salinity in irrigation water demand on the Gaza Strip

    The presented work analyzes the potential impacts of the temperature, precipitation changes and water salinity on agricultural water demand. The study was carried out on five representative orchard crops (olive, palm, grapes, citrus and guava) that cover around 83% of the orchard farms in Gaza Strip. To achieve this goal, CropWat modeling software version 8.0 is used to calculate the ...

  • Estimating the impact of seawater on the production of soil water-extractable organic carbon

    The production of water-extractable organic carbon (WEOC) during arctic coastal erosion and permafrost degradation may contribute significantly to C fluxes under warming conditions, but it remains difficult to quantify. A tundra soil collected near Barrow, AK, was selected to evaluate the effects of soil pretreatments (oven drying vs. freeze drying) as well as extraction solutions (pure water vs. ...

  • Arsenic concentrations in irrigation water, soil and selected vegetables in Bangladesh

    The effect of Arsenic (As) concentration in irrigation water on As accumulation in six selected vegetables grown during the dry season (December-May) in Bangladesh has been assessed. Three field sites were selected for the assessment, which included two As affected areas (Chandpur and Narayanganj) and one unaffected area (Bogra). The As concentrations in edible parts of the selected vegetables ...
