  • Changing climate changes soils

    Varied predictions for soil organic matter as climate changes The hottest months. The snowiest winters. Catastrophic floods and droughts. Climate change impacts lives across the world in drastic and unpredictable ways. This unpredictability also extends to the more subtle – yet still important – effects of climate change. For example, it is ...

  • 3 Great Ways to Use Your Farm Drone During the Off-Season

    You may have finished up your 2016 harvest, or perhaps getting a jump start on planning for the 2017 growing season, but think twice before putting away your farm drone for the winter. Just because you’re not actively working in the field does not mean your quad-copter shouldn’t play an active role in your off-season operations. Here are some great ways you can use your farm ...

  • Five Ways to Manage the Soil for Planting

    The soil, as the primary resource for food production and the most important tool for every farmer, is crucial for farming. Successful farming begins with the quality soil, which provides water and essential nutrients to the crops. Rich and healthy soil, combined with the appropriate amount of water and sunlight can significantly contribute to global food production. Proper soil management ...

  • Need for national soil policies for developing countries - some facts

    As a soil scientist working for more than 25 years, I am very much concerned with soil protection and conservation. In this process, I started collecting information related to national soil policies of different countries. To my surprise I could not get a well defined national soil policy for any one of the developing country? A developing country can be defined as , that country which has a ...

  • Assessing short-term responses of prokaryotic communities in bulk and rhizosphere soils to tall fescue endophyte infection

    Abstract In contrast to endophyte-free (E−) tall fescue, endophyte-infected (E+) tall fescue pastures appear to enhance soil carbon sequestration. A hypothetical mechanism that may account for the enhanced carbon sequestration is that the E+ tall fescue affects the soil microbial community or components of it that are involved in organic carbon turnover. A 60-week mesocosm study with a ...

  • The Relationship Between the Soil-Water Characteristic Curve and the Unsaturated Shear Strength of a Compacted Glacial Till

    Soils compacted at various “initial” water contents and to various densities should be considered as “different” soils from a soil mechanics behavioral standpoint even though their mineralogy, plasticity, and texture are the same. The engineering behavioral change from one specimen to another will vary due to differences in soil structure or aggregation. The shear strength of an unsaturated soil ...

  • Long-term Polyacrylamide formulation effects on soil erosion, water infiltration, and yields of furrow-irrigated crops

    Two formulations of water-soluble anionic polyacrylamide (WSPAM) are used in agriculture to reduce erosion and manage infiltration in furrow irrigations, although few if any reports have compared their effectiveness. A control and two WSPAMs, a granular form and the inverse emulsion, or oil-based liquid form, were applied to irrigation water supplied to furrows formed in a silt loam soil with ...

  • Extractability, plant yield and toxicity thresholds for boron in compost

    Boron (B) is a trace element essential to crop growth in small soil concentrations (0.2-1.5ppm), yet may produce plant toxicity symptoms readily as the amount in the soil solution increases over 2ppm. Boron is present in significant amounts in recycled materials such as municipal solid waste (MSW) and coal fly ash, and therefore composts containing these ingredients may potentially exceed ...

  • Regional Assessment of Nutrient and Pesticide Leaching in the Vegetable Production Area of Rattaphum Catchment, Thailand

    Regional groundwater vulnerability maps to indicate the impact of leaching of chemicals under different management scenarios were prepared for the Rattaphum Catchment using several leaching models and GIS techniques. The Attenuation Factor (AF) model was used to simulate the leaching potential of several pesticides for selected soils in the catchment under different rates of recharge from ...

  • Woodland Burial Sites

    The Funeralcare Co-operative Plan Bee Wildflower Meadow Creation As part of the ambitious Plan Bee project (which aims to save the plight of honey bees and pollinators across the UK), the Funeralcare Co-operative Woodland Burial Sites have been awarded funding to create bee friendly wildflower corridors. BritishFlora are managing the habitat ...

  • Moisture Content and Density of Smectites

    The measured density of smectites, using ASTM Test Method for Specific Gravity of Soils (D 854) and ASTM Method for Laboratory Determination of Water (Moisture) Content of Soil, Rock, and Soil-Aggregate Mixtures (D 2216), vary as a function of heating temperature and time. For example, the measured moisture content of air-dry Otay bentonite, heated to 110°C, varied from 16.48% moisture to 19.0% ...

  • Accumulation and mobility of heavy metals in fenugreek (Trigonella foenum-graceum L.) and tomato (Lycopersicum esculentum Mill.) grown in the field amended with urban wastes, and their composts and vermicomposts

    Accumulation of cadmium (Cd), lead (Pb), zinc (Zn), copper (Cu) and manganese (Mn) in roots, stems and leaves of fenugreek and tomato grown on lateritic soil amended with municipal solid waste, market and floral waste, and their composts and vermicomposts prepared using three earthworm species, were assessed. The heavy metal accumulation in the plant parts showed significant correlations with ...

  • Development and comparison of four methods for the extraction of antibiotics from a vegetative matrix

    Studies have shown the potential for antibiotic uptake into food crops from irrigation water and soils containing pharmaceuticals. The objective of this study was to develop and compare methods quantifying uptake of antibiotics in food crops. Four methods were evaluated utilizing freeze and thaw cell lysing (FT), mechanical maceration (MAC), tissue sonication (SON), and microwave assisted ...

  • Editorial - Slam Dunks For Compost

    ISSUE deadlines dictate life in our office. This time around, I just couldn’t stop myself from learning more about the subject matter of the article I was writing. As a result, the entire issue was prepared, and there were three pages left for one of the most exciting articles I have worked on — converting brownfields and vacant lots into highly productive farms and gardens in neighborhoods that ...

  • Carbon Sequestration: Addressing Climate Change and Food Security through Sustainable Agriculture

    Introduction To meet the demands of a growing, increasingly urban global population (approximately 9 billion by 2050), the World Bank calculates that global food production must increase by 70% in the next 35 years. This is a great challenge not only because of the volume of food that must be produced, but because agricultural conditions will not remain constant or predicable ...

  • Rice growth, grain yield, and floodwater nutrient dynamics as affected by nutrient placement method and rate

    The loss of major nutrients can be high in rice (Oryza sativa L.) fields, particularly rainfed rice, where water flowing from field to field during periods of high rainfall not only reduces the nutrient use efficiencies but also has the potential for environmental degradation. We examined the influence of deep point placement of N, P, and K briquettes compared to broadcast incorporation of N, P, ...

  • What is Hydroseeding?

    Hydroseeding is a method that can be used for planting grass for purposes of erosion control, or to grow new lawns entirely; it has been around since the 1950s. It is also an efficient, inexpensive alternative to laying sod in an area where grass or a lawn is desired. Hydroseeding can also be referred to as hydraulic mulch seeding, hydromulching, or hydroseeding. How does it work? ...
