  • Organic fertilizer drum granulator production line

    Organic fertilizer drum granulator production line Organic fertilizers are rich in nutrients needed for crop growth and can continuously supply crops with them.In addition to mineral nutrients, the decomposition of organic matter in soil produces carbon dioxide, which can be used as ...

  • Impact of Snow on Soil Greenhouse Gases

    Spring is finally in the air, and while the thermometers are slowly but steadily rising, we wanted to explore the impacts of the exceptionally snowy winter on the soil greenhouse gas emissions. For this post, we interviewed a researcher, Boris Tupek, who is based in Luke, the Natural Resources Institute Finland.  ...

  • LED or HPS for Growing Cannabis?

    “What lighting source should I use for my licensed cannabis grow?”; “I am comparing LED to HPS for my cannabis operation. Which source do you recommend?” These are questions people ask me almost on a daily basis. We have covered this question in past posts on our blog, like this one by our very own head of marketing: LEDs vs ...

  • Demystifying Light Levels for Cannabis Grows

    As more and more investors, opportunists and growers are jumping onto the green rush that is the cannabis industry right now there is also a big influx of folks who are learning as they go.  Lighting is a major purchase for this industry as a big margin of growers still prefer the better climate control and security of growing indoors and even those who choose to grow in a greenhouse are ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Enhancing growth of Chlamydomonas reinhardtii and nutrient removal in diluted primary piggery wastewater by elevated CO2 supply

    The coupling of primary piggery wastewater as a culture medium with elevated CO2 aeration is thought to be an economically feasible option for the cultivation of microalgae. However, little information is available regarding the photosynthetic characteristics of microalgae and nutrient removal from wastewater at different CO2 concentrations. It was found that elevated CO2 ...

  • Photodamaged Chloroplasts are Targets of Cellular Garbage Disposal

    Autophagy, or "self eating," is the process cells use to consume unwanted intracellular structures such as damaged organelles, excess membranes, and unneeded proteins (Mizushima and Komatsu, 2011). Typically, the unwanted structure becomes surrounded by an autophagosomal membrane, which then fuses with the membrane of either the vacuole (yeast and plants) or the lysosome (animals) to deliver its ...

  • Identification of a Chlorophyll Dephytylase Involved in Chlorophyll Turnover in Arabidopsis

    Abstract Chlorophyll turns over in green organs during photosystem repair and is salvaged via de- and re-phytylation, but the enzyme involved in de-phytylation is unknown. We have identified an Arabidopsis thaliana thylakoid protein with a putative hydrolase domain that can dephytylate chlorophyll in vitro and in vivo. The corresponding locus, CHLOROPHYLL DEPHYTYLASE1 (CLD1), was ...

  • Agroforestry Mitigates Climate Change

    Climate changes, as one of the biggest threats to a global food security, highly influence natural resources that are essential for crop production. Farming is not only affected by the impact of climate changes, but it’s also a significant contributor to global greenhouse gas emissions. Intensive farm practices that include both farm production and change of land use, directly affect the ...

  • It’s Not Easy Not Being Green: Breakthroughs in Chlorophyll Breakdown

    Plants can dispose of organs such as leaves and recycle the nutrients in these organs into new leaves, seeds, or storage organs. However, when separated from its photosystem proteins, chlorophyll can be phototoxic, absorbing light and producing high-energy electrons. The complex chlorophyll degradation pathway solves this problem by breaking down chlorophyll into colorless catabolites that are ...

  • Effect of recycled water applied by surface and subsurface irrigation on the growth, photosynthetic indices and nutrient content of young olive trees in central Iran

    Water shortage has encouraged the quest for alternative sources of water for food production and agricultural development. Recycled water (RW) is one of the most available water resources with great potential for use in farm irrigation. This experiment was carried out to investigate the use of RW as the irrigation source and its application method, subsurface leaky irrigation (SLI) system or ...

  • 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 ...

  • Can genetic engineering help quench crops’ thirst?

    Researchers around the world are exploring how GMO technology might boost food production under hot, dry conditions. Roger Deal is trying to figure out how plants remember drought. An assistant professor of biochemistry and genetics at Emory University, Deal says most plants have a kind of memory for stress. When experiencing water shortage, for example, plants close ...

  • Nitrogen and phosphorus pollution alter the mutual relationship between corals and algae

    phosphorus pollution change the relationship between the pistillata and the algae living inside its tissues, a recent study has found. The researchers say the pollutants, mainly from urban and agricultural discharges, affect algae photosynthesis and the essential transfer of carbon from algae to the coral. Nitrogen and phosphorus pollution change the relationship between the tropical coral ...

  • Extreme Makeover: Photosynthesis Edition

    Plants are far better than humans at turning sunlight into food. But they’re not nearly as good as they could be: Thanks to quirks in the systems that have evolved to capture solar energy and use it to build sugars from carbon dioxide and water, the conversion efficiency of photosynthesis is but a few percent at best. With the need to produce more crops growing even faster than human ...

  • Better photosynthesis for a better world?

    There’s no question that plants are better than most other life forms at converting carbon dioxide and sunlight into the sugars that form the basis of our global food web — and eventually, humans’ entire food supply. But fact of the matter is, with conversion rates hovering around 2 percent for our best crop fields, they’re by no means great. Even a slight increase in the ...

  • Seasteading could be the answer to sustainably feeding 9 billion people

    Self-sufficient nation states in the middle of the ocean might be our ticket to a sustainable future. Oceans cover 71 percent of Earth’s surface, yet provide less than 2 percent of the food we eat. The growing demand for seafood, however — predicted to rise to 8 percent during the next decade — from an already depleted and exhausted ocean is forcing ...
