  • Soil organic matter content effects on dermal pesticide bioconcentration in American toads (Bufo americanus)

    Pesticides have been implicated as a major factor in global amphibian declines and may pose great risk to terrestrial phase amphibians moving to and from breeding ponds on agricultural landscapes. Dermal uptake from soil is known to occur in amphibians, but predicting pesticide availability and bioconcentration across soil types is not well understood. This study was designed to compare uptake ...

  • 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 ...

  • Getting Down to the Roots: Why Soil Matters for Climate Stabilization (and More)

    Following 2015’s designation as the International Year of Soils by the UN Food and Agriculture Organization, soil carbon sequestration is experiencing something of a renaissance among policy and scientific circles. Farmers are also getting involved, most recently through the Climate Leaders program of the National ...

  • Relevance of plant functional types based on leaf dry matter content for assessing digestibility of native grass species and species-rich grassland communities in spring

    Little research has been done on the nutritive value of species-rich permanent grasslands in spite of their recognized ecological value. We proposed a new method based on the concept of plant functional type (PFT) to rank grass species and grasslands according to the organic matter digestibility (OMD) of the plant material. The PFTs are based on leaf dry matter content (LDMC). The objectives of ...

  • Effect of implementing organic farming on chemical and biochemical properties of an irrigated loam soil

    Conventional agriculture can lead to reduced soil organic matter and depletion in soil fertility. For that reason, Food and Agriculture Organization of the United Nations (FAO) recommends organic matter incorporation to soils to increase their agronomic quality. This work studies the effect of the transition to organic farming on chemical and biochemical properties of a loam soil (Xerofluvent), ...

  • Analysis of Organic Fertilizer Market

    Organic fertilizer is processed by fermenting the animal and plant residues, it not only contains major elements that plant required such as nitrogen, phosphorus and potassium, also contains microelements such as molybdenum, zinc, iron, copper and other trace elements which is ...


  • Regulation of nitrogen contents of Composts during composting first experimental results

    More than 3 Mio. Mg of compost were produced in Germany in 1998 (Wiemer and Kern 1998). Kitchen and garden waste from households as well as waste from landscaping and parks were used as substrates to a high extent. The composts were mainly used in landscaping, recultivation, horticulture, substrate production and in agriculture. Applied on cultivable land compost can improve the soil structure ...

  • Value of composted organic wastes as an alternative to synthetic fertilizers for soil quality improvement and increased yield

    One of the major problems with agricultural soils in the tropical region of the western Pacific islands is their low organic matter content, which results from rapid decomposition due to the hot and humid environment. Composted organic material is frequently applied on agricultural fields as an amendment to provide nutrients and also to increase the organic matter content and to improve the ...

  • Arsenic in irrigated paddy soils

    Natural arsenic pollution of drinking water has been reported from over 70 countries world-wide, affecting an estimated 150 million people (Ravenscroft et. al., 2008). About 50 million of these people live in Bangladesh, 30 million in India and 33 million in six other countries of south and south-east Asia. It has recently been recognised that arsenic-contaminated groundwater used for irrigation ...

  • Sustainable Soil Health

    “A Nation that destroys its soil destroys itself.” – Franklin D. Roosevelt. We have learned some harsh lessons about how to treat our soil. While most of us are aware of the problems of the past, some agricultural operations in the world are not heeding those lessons. We all know that healthy soil is essential to feed the ever-increasing ...

  • 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 ...

  • Are Conventional Farmers Becoming Interested in Organic Practices?

    Despite the fact that farming is one of the most important human activities that brings food to our tables, it contributes significantly to global pollution. Unsustainable farm practices result in the loss of biodiversity, climate changes, erosion, and the pollution of soil and water. However, when managed in a sustainable way, farming can be a source of solutions for future demands. Organic ...

  • Sugar industry press mud as alternate organic fertiliser source

    Organic materials are added to soil for improving soil physico-chemical properties. In the present study different doses of press mud along with NPK were applied to wheat crop in pot and field experiments. The increasing levels of press mud application improved soil physical conditions like increase in total porosity and reduced bulk density. Organic matter content, NPK, Fe, Mn, Zn and Cu content ...

  • Effects of wastewater irrigation on soil properties and turfgrass growth

    Reuse of treated wastewater for turf irrigation is often viewed as one way to maximize existing urban water resources. The aim of this study is to evaluate the applicability of treated wastewater for turfgrass and assess the effects of continuous use of treated water on the soil and crop. Two turfgrass plots irrigated with drinking water and treated wastewater were monitored over a two-year ...

  • Tillage effects on soil carbon balance in a semiarid agroecosystem

    Tillage systems may affect soil C sequestration, with a potential impact on crop productivity or organic matter mineralization. We evaluated crop yield, C inputs to the soil, and in situ CO2–C fluxes under no-till and conventional tillage (disk tillage) during the 3- to 6-yr period from the installation of an experiment in an Entic Haplustoll of the Semiarid Pampean Region of Argentina to ...

  • 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 ...

  • Degradation of Methyl Iodide in soil: effects of environmental factors

    Received for publication March 7, 2008. Methyl iodide (MeI) is a promising alternative to the phased-out fumigant methyl bromide (MeBr); however, there are concerns about its environmental fate following soil fumigation. Laboratory experiments were conducted to investigate the effect of various environmental factors on the rate of MeI degradation in soil. The chemical was added to soil at 48.6 mg ...

  • Ordinances To Amend Soils Boost Compost Demand

    Municipalities everywhere are realizing that some of the environmental issues they are grappling with locally may be mitigated by healthier soils. In the late 1990s, when Puget Sound Chinook salmon was listed as threatened, Washington State officials scrambled to find ways to improve water quality in the Puget Sound and protect spawning streams. They identified a number of methods to reduce ...
