  • Perfect poinsettias for Christmas? Controlling compost moisture can remove the need for chemical growth retardants

    Poinsettias, the classic Christmas pot plant, are grown in their thousands in UK nurseries from late July onwards, but growers have to rely on the use of plant growth regulators (PRGs) to ensure that the optimum height and number of bracts is achieved by early December. With protective environmental legislation threatening to reduce the availability and use of such PGR treatments, a project led ...

  • EVI vs NDVI: What’s the difference?

    The wine industry has been using aerial imaging to measure vine vigor for decades. It is becoming more and more common for vineyard managers to use vigor maps to support their decision making in the field. These maps most often use the Normalized Difference Vegetation Index (NDVI) to measure vine vigor. NDVI has been the standard in the wine industry since the Mondavi Project in 1992. NDVI is a ...

  • Measuring CO2 to Optimise the Bulk Storage of Food

    Meeting the food requirements of a growing global population is becoming increasingly difficult. Despite the need for additional food, it is estimated that 50-60% of grain is lost after harvesting, at a cost of about $1 trillion per year.1 One of the major reasons for lost grain is spoilage due to mould or insect infestation during storage.2 To provide a ...

  • Ultrasonic selectivity on depressing photosynthesis of cyanobacteria and green algae probed by chlorophyll-a fluorescence transient

    Ultrasound can inhibit cyanobacterial growth through rupturing cells, but this pathway frequently has the risk to release intercellular toxin (e.g., microcystin). Depressing photosynthesis without cell disruption may provide a new strategy to control cyanobacterial blooms using ultrasound, especially Microcystis blooms. In this work, Microcystis aeruginosa (toxic ...

  • Estimating evapotranspiration using the complementary relationship and the Budyko framework

    Several models have been developed to estimate evapotranspiration. Among those, the complementary relationship has been the subject of many recent studies because it relies on meteorological data only. Recently, the modified Granger and Gray (GG) model showed its applicability across 34 diverse global sites. While the modified GG model showed better performances compared to the recently ...

  • Science for Environment Policy

    The  economic  impact  of climate  change  on European agriculture A new study has estimated how changes to climate might affect the value of European farmland. Based on data for over 41 000 farms, the results suggest that their economic value could drop by up to 32%, depending on the climate scenario considered- Farms in southern Europe are particularly sensitive to ...

  • Comparing RGB-based vegetation indices with NDVI for agricultural drone imagery

    Abstract Agribotix conducted a post hoc test of two vegetation indices, VARI and TGI, that used only the three visible-band signals from an unmodified CMOS camera. The results were compared to NDVI, which is generally considered to be a reliable measure of field health and the underlying RGB image. While the results are somewhat encouraging in limited cases, it is clear that neither VARI nor ...

  • Validation of evapotranspiration and its long-term trends in the Yellow River source region

    In this paper, the ground observations were compared to the ERA-Interim, NCEP-DOE AMIP-II Reanalysis, MODIS ET product, and emerging offline SEBS ET data sets in the Yellow River source region of the Tibet Plateau. In general, the slopes of linear least squares exhibit differences, with ERA-Interim, NCEP–DOE, MOD16, and SEBS slopes of 0.88 ± 0.05, 0.64 ± 0.07, 0.66 ± 0.17, and 1.24 ± 0.97 ...

  • The Value of Humic Substances in the Carbon Lifecycle of Crops

    Everyone who works in agriculture is aware of the basic lifecycle of crops: plants are seeded, they are nourished and they grow, they are harvested, and what is not consumed by (us) higher life forms is returned to the soil—where it is broken down through mineralization and by microorganisms so that it can be used to nourish the next cycle of crops. That relatively simple scenario is ...

  • The efficacy of disinfectants against plant pathogens

    In late 2015, a journal article from the European Journal of Plant Pathology was published on research regarding the efficacy of different disinfectants against plant pathogens in irrigation water. All testing as done by the Department of Primary Industries here in Australia for the horticulture and agriculture industries.  The disinfectants tested included chlorine, chlorine dioxide (using ...

  • 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 ...

  • Landscape trees benefit from potassium-based superabsorbent polymer-amended backfill soil

    Weiner (1975) put it aptly when he stated that “However rewarding the act of tree planting may be, watching a young tree slowly die can be spiritually defeating.” Landscape plants, noted Richard Harris (1983) in his well-known “Arboriculture” book, “probably suffer more from moisture-related problems than from any other cause.” The success of tree planting ...

  • Farming in a Controlled Environment

    There is considerable pressure on today’s farmers. This is because of farming, as a special type of manufacture, largely depends on climate and natural resources. Climate changes have led to unpredictable weather conditions that can endanger farmer’s efforts with frequent hail, frost or drought. With increased global population, that is predicted to reach a number of 9.6 billion by ...
