  • Writing an equation for soil success

    Soil isn’t one size fits all. It may look the same under your feet – but under a microscope, that’s a different story. A plant’s roots, tiny bugs – these things can tell one soil from another quite easily. Soil scientists typically measure different aspects of soil — how much air it contains, how well it retains water, heat, and more — to ...

  • Research to restore the fertility of earth`s soils

    In keynote addresses at the FAO Workshop on Sustainable Agriculture in Riyadh, Saudi Arabia on April 28 and April 29, 2009, soil fertility experts from the Nutrition Security Institute, (NSI) a non-profit organization located in Bellevue, Washington, presented advances and understandings in biotic soil fertility as a proven solution to the serious problems facing global agriculture. Their dual ...

  • Effects of chemical fertiliser and animal manure on soil health compared

    Fertilising crops with cattle manure can lead to better soil quality than when synthetic fertiliser is used, recent research indicates. The use of cattle manure in the study led to greater soil fertility by encouraging higher microbial activity, and the researchers suggest that it could potentially improve soil’s ability to cope with periods of difficult growing conditions. The ...

  • Cultivation affects pesticide–soil interactions

    Pesticides are often used to enhance crop production by killing unwanted animals or plants. Unfortunately, they can also negatively impact humans and environmental health. The degree of impact, in part, depends on the fate and behavior of pesticides in the environment. The latter is governed by complex interactions of pesticides with soil components. One such important interaction is sorption of ...

  • Controlled ‘reset’ for nematode-infested soil

    Harmful nematodes that damage the soil can be controlled by creating an environment in which they are temporarily deprived of oxygen. Covering the soil with plastic film or a layer of water encourages anaerobic bacteria to produce fatty acids, which will kill most nematodes. “It does sometimes take a while,” says Leendert Molendijk, soil expert at Wageningen UR. Molendijk and his ...

  • `We need a new approach for better soil`

    ‘Dutch agricultural soils are not future-proof’ was a widely accepted statement at the final meeting of the Public Private Partnership (PPP) Sustainable Soil. Breeders, chain partners, suppliers, the government and the science sector see a gradual deterioration in soil quality and are joining forces within the PPP to find a solution. “It isn’t a simple matter,” says ...

  • A model to measure soil health in the era of bioenergy

    One of the biggest threats to today’s farmlands is the loss of soil organic carbon (SOC) and soil organic matter (SOM) from poor land-management practices. The presence of these materials is essential as they do everything from providing plants with proper nutrients to filtering harmful chemical compounds to the prevention of soil erosion. Sustainable management practices for crop residues are ...

  • Method developed to measure solute movement in soils

    Scientists from Aarhus University and Aalborg University in Denmark have developed a new method for measuring the movement of solutes in intact soil. Improving on the existing method, the new procedure can be used on intact, undisturbed soil and provides more confident estimates. Movement, or diffusion, of solutes in soils is involved in many processes of agronomical, environmental and technical ...

  • Phosphorus-rich soils support larger invertebrates

    In a recent study, researchers have defined the relationship between soil conditions and nutrients with the health of soil ecosystems. The results suggest that organic grassland, rich in phosphorus, is supportive of large populations of bigger invertebrates. All living things are made up of chemical elements in certain proportions and the availability of these elements in the environment can ...

  • Target the crop not the soil - to reduce fertiliser use

    Feed the crop not the soil’ is the message of a new review into sustainable phosphorus use. Currently, phosphorus fertiliser is applied to the soil, and plants then take it up through the roots. However, more precise nutrient management is needed on farms, the researchers say, so that the phosphorus is targeted at the crop just as it needs it. Modern agriculture is dependent on phosphorus, ...

  • Fewer indicators may be sufficient to assess soil quality

    Although soil quality is best assessed using a wide range of indicators, a smaller set may be more practical and still provide the necessary information needed to choose between land management systems. This is the conclusion of a new study in Brazil that evaluated three different indexes of soil quality based on three sets of indicators. In order to ensure farming is sustainable, there is a ...

  • Using rotation crops to improve soil quality

    Soil quality issues are being researched within two crop rotation experiments that started in 1994 at Narrabri. They compare several crop rotations that include or exclude legume phases. The data presented here relate to the most recent 2-year cycles of these experiments. Following cotton harvest at the end of the previous cycle, rotation crops are sown (winter cereal, faba beans (grain) or vetch ...

  • Soil biodiversity: functions, threats and tools for policy makers

    Human societies rely on the vast diversity of benefits provided by nature, such as food, fibres, construction materials, clean water, clean air and climate regulation. All the elements required for these ecosystem services depend on soil, and soil biodiversity is the driving force behind their regulation. With 2010 being the International Year of Biodiversity and with ...

  • Eucalyptus essential oil as an alternative to chemical pesticides

    Controlling pests with natural products can have greater environmental benefits than using chemical pesticides. A recent study reviews the use of eucalyptus essential oil as a natural pesticide and offers recommendations for its future application. Chemical pesticides have played a major role in securing food supplies the world over. However, excessive use has led to increased environmental ...

  • Fungi and roundworms as non-chemical substitutes for pesticides

    The use of some pesticides is a recognised concern for health and the environment. A new UK study identifies some naturally occurring alternatives to control wireworm, a widespread pest of potatoes. The wireworm causes major problems in arable crops, including potatoes, in many parts of the world. Wireworms are the larvae of click beetles. Their damage to potatoes can drastically reduce yield. ...

  • Soil science society of America announces 2010 award recipients

    The Soil Science Society of America (SSSA) will present the following 2010 Awards during their Annual Meetings on Oct. 31-Nov. 3 in Long Beach, CA, www.acsmeetings.org. Kirk Scheckel – Marion L. and Chrystie M. Jackson Soil Science Award. Kirk Scheckel is a research soil scientist in the National Risk Management Research Laboratory of ...

  • Increasing diversity through crop rotation boosts soil microbial biodiversity and productivity

    Planting a variety of crop species in rotation in agricultural fields increases the diversity of soil microbes below ground, recent research has found. This in turn positively affects soil organic matter, soil structure and aids the healthy functioning of the soil. The researchers say that rotational diversity can help farmers to grow crops in a more sustainable way that promotes soil stability. ...

  • Genetic change could make crops thrive on salty soils

    Scientists have genetically modified plants to tolerate high levels of salt — offering a potential solution to growing food in salty soils. The researchers inserted a gene to remove salt — in the form of sodium ions — from water taken up by the plant before it reaches the leaves, where it does most damage. The research was published in The Plant Cell this month (7 July). High salinity reduces ...

  • Ultra-fine coatings on sediment grains influence nitrate and sulfate storage in soil

    Tiny sediment grains are covered with a very fine-grained, complex mixture of minerals in an open fabric that results in a large surface area in contact with water between the grains. Scientists at the U.S. Geological Survey (USGS) are studying this microscopic layer and finding that the mineral composition of these coatings on sediment grains in the unsaturated zone (i.e., between land surface ...
