  • Cogeneration experience with Clarke Energy: Carthage Grains CHP Plant, Tunisia

    Carthage Grains is the leader in the Maghreb in the trituration of the soya bean: production of oil and soybean meal. The process of Carthage Grains consumes electrical and thermal energy in the form of steam (30 to 35 tonnes per hour at 12 bar pressure). As the supplier of Nejma Oil (a Clarke Energy customer since 2012), the choice of Carthage Grains for GE’s Jenbacher gas engine ...

  • 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 ...

  • Evaluation of composted green waste in ornamental container-grown plants: effects on growth and plant water relations

    Ornamental nurseries extensively utilize peat in commercial soilless potting media, but its use as an organic amendment with a superior water holding capacity is challenged by economic and environmental pressures so potential alternatives to peat need to be investigated. In our experiment, commercially available peat-based soilless mixes were amended with increasing composted green waste (CGW) ...

  • Effects on macronutrient contents in soil-plant irrigated with different quality waters and wastewaters

    The goals of this research were focused on investigating the effects of irrigation with untreated wastewater, ozone-enhanced primary treated wastewaters (O3EPTW), tap water and tap water + fertilizer on the macronutrient content in soil and plant tissues. The effect on plant development was evaluated by growing Lactuca sativa in soils irrigated with these different quality ...

  • Coal Processing Plant and Machines

    Coal Preparation plant generally use gravity process equipment to separate the refuse from the product (coal). Coal has a specific gravity between 1.35 and 1.5, while the refuse rock has a Specific Gravity of 2.1 to 2.3. Heavy Media is the most popular method of cleaning coarse sizes, jig plants are probably the second most common ...


  • Water plant covers bring operational, safety benefits - case study

    It was time to upgrade the water treatment plan, again. For the third time since commissioning the Kuiper Water Treatment Plant, the City of Aurora, CO, and its engineers, CH2M Hill, began planning another upgrade project. This 70 mgd direct filtration plant was originally built in the late 1960s and had already been expanded twice between 1972 and 1976. Now the plant was to be upgraded again to ...

  • Simple models for carbon assimilation by plants

    The detailed processes in photosynthesis are complicated and hard to model. In many cases, however, it’s possible to simplify the model by focusing on one or more of the limitations to assimilation. Carbon Assimilation Simplified: Light and WaterIn simplest terms, carbon assimilation involves the chemical transformation of carbon dioxide and water to carbohydrate and oxygen within the leaves of ...

  • Desiccation-tolerant plants in dry environments

    The majority of terrestrial plants are unable to survive in very dry environments. However, a small group of plants, called ‘resurrection’ plants, are extremely desiccation-tolerant and are capable of losing more than 90% of thecellular water in vegetative tissues. Resurrection plants can remain dried in an anabiotic state for several years and, upon rehydration, are able to resume normal growth ...

  • Five Ways to Manage the Soil for Planting

    The soil, as the primary resource for food production and the most important tool for every farmer, is crucial for farming. Successful farming begins with the quality soil, which provides water and essential nutrients to the crops. Rich and healthy soil, combined with the appropriate amount of water and sunlight can significantly contribute to global food production. Proper soil management ...

  • The Best Practices for Using Plant Residues

    Plant residue are crop materials such as stems, leaves, and roots, that are left on the field after the harvest. In the past, farmers considered crop residue to be trash, that was usually destroyed by fire. However, today this practice is not recommended and highly is not used by farmers. There are two different ways to manage crop residues. The first method is tillage prior planting when plant ...

  • Using Compost To Control Plant Diseases

    Losses due to soilborne diseases on some greenhouse, nursery and vegetable crops can amount to thousands of dollars per acre annually. Until the 1930s, organic amendments — consisting of animal and green manures, coupled with crop rotation — were principal methods of control. But these approaches were largely abandoned for reasons of cost and inconvenience after commercial fertilizers and the ...

  • Water Stress

    Plants experience water stress either when the water supply to their roots becomes limiting, or when the transpiration rate becomes intense. Water stress is primarily caused by a water deficit, such as a drought or high soil salinity. Each year, water stress on arable plants in different parts of the world disrupts agriculture and food supply with the final consequence: famine. Hence, the ability ...

  • Estimating plant-available water using the simple inverse yield model for claypan landscapes

    Plant-available water (PAW) is one of the fundamental soil factors affecting crop yield, yet quantitative determination of plant-available water capacity (PAWc) at a field scale has been challenging. A simple inverse yield model (SIYM) has been devised and shown to be successful in estimating PAWc at a field scale for well-drained soils by matching simulated corn (Zea mays L.) yield with measured ...

  • Influence of rainfall interception by endemic plants versus short cycle crops on water infiltration in high altitude ecosystems of Ecuador

    Owing to their high water retention, the volcanic ash-soils of the Northern Andean highlands (páramos) can be considered as natural ‘water storage tanks’ for drinking water and for irrigation. Vegetation plays an important role in transferring rain to the soil and in controlling the soil water content. To assess this role, we quantified the stemflow process under rainfall simulations for seven ...

  • Agriculture plant nursery application case studies

    Challenge A plant nursery company had water quality issues from the well water source that there were using for irrigation purposes in their plant growing operations. These water quality issues including total dissolved salts (TDS) around 2500 mg/l, as well as turbidity, mineral hardness and microbiological contaminants. The plants were slow growing. Solution ...

  • Case study: fish processing plant wastewater treatment

    Abstract This presentation describes the full scale installation of a wastewater treatment system at the Ocean Gold Seafood ("OCS") plant in Westport, Washington, USA. Local Government requires that fish processors remove total suspended solids (TSS), fats, oil and grease (FOGs) and colloidal materials almost completely in order to allow for efficient disinfection. The OCS plant had only ...

  • Impact of plant assemblages on nutrient removal in constructed wetlands

    Four different mesocosm scale constructed wetlands - monoculture (Carexstipata), self–designed (passive) community, mixed planted monoculture–passive community and a non–vegetated control - were compared to assess the effects of plant community composition on the removal of inorganic nutrients from agricultural runoff (synthetic tile water). The mixed and self–designed systems consistently ...

  • Case Study - Onion and Garlic Dehydration Plant

    Empire, Washoe County, Nevada, USA Geothermal Development Associates (GDA) designed a geothermal heating system for a large commercial vegetable dehydration plant located in the remote San Emidio Desert, about 160 kilometers north of Reno, Nevada, USA. Phase I of this project utilizes 63 l/sec of geothermal brine at 150°C to dehydrate either onions or garlic, depending ...
