  • LG Sound, controlling algae in irrigation reservoirs

    Algae growth in irrigation water can cause a serious problem. Algae in irrigation tanks can clog the entire irrigation system, such as the pumps, filters, drip-installation and sprinkler nozzles. Besides that the algae and their by-products can also be spread over the irrigated area. In addition, some types of fungi, also present in these waters, can be harmful for the plants grown. Typical ...

  • Lg Sonic Ultrasonic Algae and biofilm control for irrigation case study

    Water used for irrigation can contain high levels of nutrients, some of these nutrients are beneficial for the plants watered, but can also lead to extensive algal growth. Algae in irrigation tanks can clog the irrigation system and can also be spread over the irrigated area. In addition, some types of fungus, also present in these waters, can be harmful for the plants grown. Therefore the ...

  • Cultivating energy crop production

    A NEW Farm Bill is moving through the Congressional legislative process. Along the way, commercial agriculture is debating the energy impacts of future corn and soybean production. The growth of corn-based ethanol and soybean-based biodiesel has created competition for the feed inputs into animal agriculture, namely corn and soybeans. While most of agriculture discusses energy production from ...

  • Toxicity of major cations and anions (Na+, K+, Ca2+, Cl−, and SO 42−) to a macrophyte and an alga

    In many freshwater systems around the world, the concentrations of major ions (Na+, K+, Ca2+, Mg2+, Cl−, HCO 3−, CO 32−, and SO 42−) are exhibiting increasing trends, approaching the concentrations historically found mainly in estuaries. The objectives of the present study were to determine at what concentrations these salts are toxic to an aquatic plant and a green alga, to investigate two ...

  • Recovery of photosynthesis and growth rate in green, blue–green, and diatom algae after exposure to atrazine

    We evaluated the recovery of photosynthesis and growth rate in green (Pseudokirchneriella subcapitata), blue‐green (Anabaena flos‐aquae), and diatom (Navicula pelliculosa) algae after pulsed exposure to atrazine. Subsequent to a grow‐up period of 24 to 72 h to establish requisite cell density for adequate signal strength to measure photosystem II (PSII) quantum yield, algae were exposed to a ...

  • Control of algal production in a high rate algal pond: investigation through batch and continuous experiments

    For decades, arid and semi-arid regions in Africa have faced issues related to water availability for drinking, irrigation and livestock purposes. To tackle these issues, a laboratory scale greywater treatment system based on high rate algal pond (HRAP) technology was investigated in order to guide the operation of the pilot plant implemented in the 2iE campus in Ouagadougou (Burkina Faso). ...

  • Simulations of nutrient emissions from a net cage aquaculture system in a Brazilian bay

    Hydrodynamics and transport simulations were conducted with the modeling software TELEMAC-2D on Icó-Mandantes bay, a branch of the Itaparica reservoir. The bay has a maximal operational water level amplitude of 5 m and is suffering from eutrophication and algae bloom. Therefore, we investigated low and high water level scenarios with two different high resolution meshes, with the purpose to ...

  • Qualitative algal analysis from the fish-gut: Tested in the rice fish cropping system

    Abstract: Algae constitute a major proportion of fish food in rice-fish culture system. Study of algal preferences and their availability in the natural environment might be important for developing natural fish feed. Preparation of formulated feeds using under-exploited materials such as algae not only reduces production costs, but also increases procurement accessibility of locally available ...

  • Seasonal Dynamics of Periphyton in a Large Tropical Lake

    Tropical aquatic systems are generally assumed to have little seasonality in productivity patterns. However, this study indicated that there was substantial seasonal variation in epilithic productivity and biomass in tropical Lake Tanganyika, due primarily to seasonal patterns in lake hydrodynamics that influence nutrient availability. Although they support much of the lake’s biological ...

  • Field trial carried out in the ebro valley, Spain case study

    Rice farmers in Spain experience two major problems with their rice crops: After the flooding and fertilisation of the rice fields algal growth rapidly develops and covers the surface of the water in the paddy. This greatly reduces the availability of sunlight received by the seedlings until they have grown above the water level. This results in early stage plant loss which can be severe. The ...

  • Salmon aquaculture could incorporate seaweed and sea urchins to reduce nitrogen enrichment

    Farming fish together with seaweed and other species could help improve the sustainability of aquaculture and reduce pollution. A new study provides a tool for designing sustainable fish farming systems and calculates their potential to recycle waste. An example of a salmon farming system incorporating seaweed and sea urchins could reduce nitrogen releases to the environment by 45%. Over half of ...

  • The advantages and disadvantages of culturing fish.

    The advantages and disadvantages of culturing fish. Experts develop practical recommendations for decision-makers, scientists and producers for a sustainable development of Mediterranean aquaculture. Human demand for fish is growing steadily. With fisheries decreasing worldwide, aquaculture is becoming an important socio-economic alternative and a source of proteins and healthy oils. ...

  • Monitoring greenhouse gases from biofuel crops

    Global issues such as climate change and energy security have driven rapid growth in renewable energy production - wind, solar, tidal, geothermal, hydro, biofuels etc. However, logically, each of these methods should deliver a net benefit in terms of greenhouse gas (GHG) reduction, so researchers in the United States have employed portable FTIR analysers to study the GHG emissions of biomass ...

  • Nutrient Regulation on Streams: The Macrophyte Quandary

    ABSTRACTSince promulgation of the Clean Water Act in the 1970s and implementation of technology-based treatment requirements, such as secondary treatment for publicly owned treatment works, the nation’s water quality has improved dramatically. Current water quality concerns are no longer attributed to excessive loads of carbonaceous and nitrogenous biochemical oxygen demand. Rather, the largely ...
