  • Agronomic performance of different pea cultivars under various sowing periods and contrasting soil structures

    Yield variability of spring pea (Pisum sativum L.) in farmers' fields is mainly due to soil compaction at sowing and abiotic stresses during the reproductive period. Winter peas flower earlier, and thus should be less sensitive to abiotic stress at the end of the cycle, but because of their sensitivity to frost they must be sown late in autumn when soils are very wet. Pea breeders are working on ...

  • Electronic sow feeding system

    In 2013, the company Börde Porc GmbH & Co. KG set up a modern sow management farm in one of the most fertile plains of Germany, the so-called "Magdeburg Börde". The new houses provide space for around 2,400 productive sows and 600 gilts. Once again, Big Dutchman was allowed to prove its capability by providing the required sow equipment.  To date, Börde Porc's location ...

  • Sowing the seeds of smarter transport policy

    Did we miss something? Last year, the European Commission didn’t propose a single new legislative measure to clean up transport. To be fair, it has been spending most of its time worrying about the future of the Eurozone. As a result, for T&E this was the sort of year where seeds for smarter transport policy were sown. We’re optimistic that next year could bring a decent crop of ...

  • Nitrogen Fixers

    Here’s a bit of geeky plant science. On this image of the roots of white clover, you can plainly see bumps along the roots that are called nodules. Over millions of years, the plant has evolved a symbiotic relationship with certain species of soil-dwelling bacteria called Rhizobia. This group of bacteria has the ability to take nitrogen from the atmosphere and “fix” it by ...

  • Sow management: Bongdong trumpets stellar production - Case Study

    The past decade has seen changes in the South Korean pig industry landscape. From more than 12,000 pig farms in 2005, the number declined to 6,000 in 2012. Despite this, total pig inventory in the country has gone up to almost 10 million heads from roughly nine million heads during the same period, evidence of the growing efficiency and productivity of the country’s pig producers.  ...

  • Goosegrass and Bermudagrass competition under compaction

    Goosegrass (Eleusine indica L.) is a serious weed in trafficked areas of bermudagrass (Cynodon spp.) golf and sports turf. The objective of this study was to evaluate soil compaction and canopy cover as determinants of goosegrass competition in bermudagrass turf in sand soil. Goosegrass cover, plant density, and soil penetration resistance (SPR) were measured in traffic and no-traffic plots in ...

  • Emergence of polymer-coated corn and soybean influenced by tillage and sowing date

    No tillage often delays soil warming and drying, thus sowing too early in the spring may compromise seed viability due to prolonged exposure to cold and wet soil in the northern Corn Belt. Coating seed with a temperature-activated polymer may circumvent the adverse effects of exposing seeds to cold and wet soil. Germination and emergence of noncoated and polymer-coated corn (Zea mays L.) and ...

  • How three U.S. mini-farms are sowing the seeds of global food security

    Tiny, biointensive operations show smallholder farmers from around the world how they can grow far more food than conventional approaches. Her face shaded by a wide-brimmed straw hat, Olawumi Benedict is cheerfully tending to her “little babies” — kale seedlings growing in shallow wooden flats until they’re hardy enough for transplantation into soil beds. Three miles over ...

  • Nitrogen fixation of Sulla under Mediterranean conditions

    Sulla coronaria (L.) B.H. Choi & H. Ohashi (=Hedysarum coronarium L.) is a Mediterranean forage legume grown extensively in rainfed Italian environments. Here we report the field quantification of its seasonal and annual N fixation, using the 15N isotopic dilution (ID) method, the influence of various nonfixing reference species on these estimates, and the allocation of fixed N between the ...

  • Sowing and flowering delays can be an efficient strategy to improve coexistence of genetically modified and conventional Maize

    The coexistence between genetically modified (GM) and non-GM maize (Zea mays L.) fields is subjected to regulation in several countries. A strategy to reduce cross-pollination from GM to non-GM fields was evaluated, on the basis of reducing the flowering coincidence by sowing at separate times. The trial included narrow plots in which transgenic maize was sown before, simultaneously, and after ...

  • Consolidation Behavior of Clayey Soils Under Radial Drainage

    For Barron´s degree of consolidation, Ur, versus the time factor, Tr, relationship for soils undergoing consolidation with radial drainage for the equal vertical strain condition, a simple method has been developed to determine the value of the coefficient of consolidation with radial drainage, cr. Theoretical log10(d2e/t) versus Ur curves where de is the diameter of influence and t is the real ...

  • Valuation and Management of Fishing Resources Under Price Uncertainty

    The traditional expected-net-present-value methods cannot properly capture the management flexibility and strategic value aspects of a fishery, and may understate its value. Instead, this paper develops a Real Options model to conceptualize and evaluate fishery exploitation flexibility. Specifically, general models to value the opportunity to either exploit or invest in a fishery are presented. ...

  • Lessons learned from potato growers down-under

    Andy Alexander, specialist potato consultant and agronomist, has provided advice across the UK and Australia for over 35 years, and has travelled to the southern continent over 17 times. He explains how adapting to change in a volatile climate has been key to success for growers in Australia, and what lessons UK growers can take from this. “My role is to provide business ...

  • Regeneration of teak forests under joint forest management in Gujarat

    In order to understand the impact of JFM in Gujarat, a study was conducted in three divisions viz., Baria, Rajpipala and Sabarkantha covering 24 villages. Vegetation parameters such as species richness, density of trees, basal areas, Shanon Weiner's diversity index, woody biomass and MAI were observed and compared with control plots in a non-JFM village. Stem density, species richness, species ...

  • Simulation of soil carbon dynamics under sugarcane with the CENTURY model

    Currently there is a trend for the expansion of the area cropped with sugarcane (Saccharum officinarum L.), driven by an increase in the world demand for biofuels, due to economical, environmental, and geopolitical issues. Although sugarcane is traditionally harvested by burning dried leaves and tops, the unburned, mechanized harvest has been progressively adopted. The use of process based models ...

  • Antibiotics in groundwater under locations with high livestock density in Germany

    Antibiotics are deployed in large quantities both in human and in veterinary medicine. Studies show that antibiotic residues occur in the environment (e.g. soil and surface waters). In some cases they were also detected in ground and drinking water. However, the degree of groundwater pollution by antibiotic residues from livestock farming is unknown. Therefore, the federal environment agency ...

  • Comparison of runoff quantity and quality under annual cropping and forages

    Conversion from annual cropping to perennial forages may be a beneficial management practice (BMP) to reduce runoff quantity and improve surface water quality. Runoff variables were determined in two 30 ha producer's fields over 4 years (2004–2007) using a rainfall simulator. Field 1 was cropped to barley (Hordeum vulgare L.) in 2004 and then an alfalfa (Medicago sp.) and grass mix used for ...

  • Effects of cadmium and arsenic on Pteris vittata under hydroponic conditions

    Pterisvittata is known to hyperaccumulate arsenic, and a large number of studies on this fern species can be found in the literature aimed at evaluating its behavior when coexposed to other toxic elements. In the present study, P.vittata was treated with different concentrations of As and/or Cd in a hydroponic system, that is, under complete bioavailability of the elements, with the objective of ...

  • Temporal yield variability under conventional and alternative management systems

    Year to year variation in yield is an inherent risk associated with crop production and many growers rely on intensive mechanical or chemical inputs to preserve crop yield in the face of fluctuating environmental conditions. However, as interest grows in alternative crop management systems which depend less on external inputs, determining the degree to which management systems can impact the ...
