  • Ancient Trick for Soil Improvement

    Today, when every farmer is facing a battle of food production for a growing population, crop production has become much more intensive. These farm practices, which usually include monoculture, harm soil nutrient composition and deplete this valuable natural resource. Using the same crop on the same field keeps draining the soil of essential nutrients. Monoculture combined with intensive farm ...

  • Potassium and winter hardiness

    The role of Potassium in metabolic processes such as protein synthesis and the movement of sugars within the plant is now well understood and recognised as crucial for maximising quality and yield. But it is now known Potassium also plays a significant role in helping crops resist disease and environmental stresses during winter dormancy and ensuring optimum supplies of Potassium to see crops ...

  • Maximising herbicide efficiency - Case Study

    The most important component in achieving an effective and efficient spray solution will always be the water source, so in hard water areas, using a good quality water conditioner is essential to prevent chemical breakdown and maximise herbicide performance. Around the country water can range from soft to hard and its pH can also vary depending on location. From Yorkshire down ...

  • Biobased Economy opportunities for North-Netherlands

    The three Northern provinces of the Netherlands could join forces to become a major producer and supplier of renewable resources for the regional production of ‘green’ chemicals, plastics and animal feed. This is one of the conclusions from research carried out by Wageningen University & Research, Greenlincs and the University of Groningen. Close collaboration with the German ...

  • An autophagy-related kinase is essential for the symbiotic relationship between Phaseolus vulgaris and both rhizobia and arbuscular mycorrhizal fungi

    Eukaryotes contain three types of lipid kinases that belong to the phosphatidylinositol 3-kinase (PI3K) family. In plants and Saccharomyces, only PI3K class III family members have been identified. These enzymes regulate the innate immune response, intracellular trafficking, autophagy, and senescence. Here, we report that RNAi-mediated down-regulation of common bean (Phaseolus vulgaris) PI3K ...

  • Decoding the Molecular Network that Drives Hypocotyl Elongation

    Auxin and brassinosteroid (BR) promote cell expansion through interdependent and synergistic pathways (reviewed in Hardtke et al., 2007). Although the biosynthetic pathways that produce these phytohormones have been characterized and the downstream response factors that trigger cell expansion are known (Oh et al., 2014), the transcriptional network that brings about localized changes in auxin and ...

  • Synergism between inositol polyphosphates and TOR kinase signaling in nutrient sensing, growth control and lipid metabolism in Chlamydomonas

    The networks that govern carbon metabolism and control intracellular carbon partitioning in photosynthetic cells are poorly understood. Target of rapamycin (TOR) kinase is a conserved growth regulator that integrates nutrient signals and modulates cell growth in eukaryotes, though the TOR signaling pathway in plants and algae has yet to be completely elucidated. We screened the unicellular green ...

  • How the Earthworm Improves the Soil

    Nature has ways of converting vegetable and mineral raw materials into high-quality products. The inconspicuous earthworm provides striking example — it is a minirefinery in the soil. The dew worm or common earthworm, which is native to Europe, is just one of more than 3000 earthworm species in the world. About 30 centimeters long, the powerful earthworm digs ...

  • Mixture toxicity of copper, cadmium and zinc to barley seedlings is not explained by antioxidant and oxidative stress biomarkers

    Metal mixture toxicity analysis to plants is complicated by mutual interactions. Here, mixture effects of zinc (Zn), cadmium (Cd) and copper (Cu) on barley (Hordeum vulgare L.) root elongation were analysed using oxidative stress parameters. The hypothesis was that toxic mixture effects on plant growth are better explained by biochemical parameters than by exposure information, because the ...

  • Can superfoods boost the planet’s health, too?

    As demand for African and Asian tree-based superfoods grows, researchers and entrepreneurs eye ways to maximize benefits for the environment. It can seem like new health food fads pop up every week — fads that often fade as quickly as they appear. Two gaining steam lately, though, may be worth a longer look: baobab and moringa. Traditional fare in parts of Africa (and for moringa, ...

  • Features of impulse sprinkling technology

    The principle of non-stop water supply to plants and soil in accordance with their water intake is progressive. Drip irrigation and impulse sprinkling correspond to this principle. Drip irrigation provides optimal water and nutrient regimes directly to the root system of plants. However, this irrigation is not effective enough under conditions of high temperature (over 25–35 °C) as growth ...

  • Barley root hair growth and morphology in soil, sand, and water solution media and relationship with nickel toxicity

    Barley, Hordeum vulgare (Doyce), was grown in the three media of soil, hydroponic sand solution (sand), and hydroponic water solution (water) culture at the same environmental conditions for 4 d (days). Barley roots were scanned and root morphology was analyzed. Plants grown in the three media had different root morphology and Ni toxicity response. Root elongations and total root lengths ...

  • Germination and early plant development of ten plant species exposed to TiO2 and CeO2 nanoparticles

    Ten agronomic plant species were exposed to different concentrations of nano titanium dioxide (nTiO2) or nano cerium oxide (nCeO2) (0, 250 µg/mL, 500 µg/mL and 1000 µg/mL) to examine potential effects on germination and early seedling development. We modified a standard test protocol developed for soluble chemicals (OPPTS 850.4200) to determine if such an approach might be useful for screening ...

  • Enhanced sonochemical degradation of tetracycline by sulfate radicals

    Tetracyclines (TCs) are widely used antibiotics in human and veterinary medicine and as growth promoters in the world. Sulfate radical-based advanced oxidation processes have been of great interest due to the high oxidizing potential of sulfate radical to degrade refractory organic pollutants in aqueous solution. In this study, the degradation of antibiotic TC in aqueous solution by ...

  • Is the chronic Tier‐1 effect assessment approach for insecticides protective for aquatic ecosystems?

    We investigated the appropriateness of several methods, including those recommended in the Aquatic Guidance Document of the European Food Safety Authority (EFSA), for the derivation of chronic Tier‐1 Regulatory Acceptable Concentrations (RACs) for insecticides and aquatic organisms. The insecticides represented different chemical classes (organophosphates, pyrethroids, benzoylureas, insect ...

  • Control of Microthrix parvicella by aluminium salts addition

    Aluminium and iron chloride were added to a biological nutrient removal pilot plant (1,500 population equivalent) treating urban wastewater to investigate the control of Microthrix parvicella bulking and foaming by metallic salts. Monitoring plant performance over two 6-month periods showed a slight impact on the removal efficiencies. Addition of metallic salts (Me; aluminium or aluminium + ...
