  • Prevent harmful conditions from damaging crops with sensor alerts

    Your algae monitoring and control system is all set up, humming along efficiently, and the algae is growing well. Your solenoids are controlling the CO2 input so that your pH is always on target. Coolers (or heaters) are controlling your temperature. Maybe you even have automatic harvesting based on the density of your algae. But what happens if one of the devices breaks down? Pumps, valves, ...

  • Measurement of photosynthetic performance in crop plants under South African climatic conditions

    A key objective of the research conducted by Dr Riekert van Heerden (riekert.vanheerden@nwu.ac.za) at North-West University, Potchefstroom, South Africa and Drs Kobie de Ronde (and team members) and Joseph Asiwe at the Agricultural Research Council (ARC–Vegetable and Ornamental Plant Institute & ARC–Grain Crop Institute) is to increase the production of crops important for the ...

  • Strategies to improve nitrogen use efficiency in winter cereal crops under rainfed conditions

    Developing fertilizer strategies that increase nitrogen use efficiency (NUE) could reduce unnecessary input costs to farmers and environmental impact of N losses. Two field experiments were performed in northern Spain to evaluate alternative N fertilization strategies to improve NUE in winter cereal crops (wheat [Triticum aestivum L.] and barley [Hordeum vulgare L.]). The strategies were: (i) ...

  • Alternative crop rotations under mediterranean no-Tillage conditions: biomass, grain yield, and water-use efficiency

    In Mediterranean semiarid areas, barley (Hordeum vulgare L.) and wheat (Triticum aestivum L.) are major crops because they are well adapted to limited-water environments. In this study we tested the performance of alternative rotations to the typical barley and wheat monocultures in a rainfed Mediterranean semiarid area of northeastern Spain under a no-tillage (NT) system. Four rotations were ...

  • Co-digestion of bovine slaughterhouse wastes, cow manure, various crops and municipal solid waste at thermophilic conditions: a comparison with specific case running at mesophilic conditions

    A co-digestion process was evaluated when mixing different ratios of agro-industrial residues, i.e. bovine slaughterhouse waste (SB); cow manure (M); various crop residues (VC); and municipal solid waste (MSW) by anaerobic batch digestion under thermophilic conditions (55 °C). A selected study case at mesophilic condition (37 °C) was also investigated. The performance of the ...

  • Crop response to rotation and tillage in peanut-based cropping systems

    Production of peanut (Arachis hypogaea L.) in reduced tillage systems has increased in the United States during the past decade. However, interactions of tillage system and crop rotation have not been thoroughly investigated for large-seeded, Virginia market type peanut. Research was conducted at two locations in North Carolina during 1999 to 2006 to compare yield of corn (Zea mays L.), cotton ...

  • Jojoba: A Potential Desert Oil Crop

    Jojoba (Simmondsia chinensis usually grows to a height of 1-2m and may reach heights of three meters or more under ideal growing conditions. S. chinensis has a normal life span of at least 100 years and may live more than 200 years. Pollination is via wind or insects. The fruit is a green capsule enclosing as many three seeds. When ripe (3-6 months after fertilization) the capsule splits and ...

  • Emissions from Crops - POST Note

    Agriculture contributes 9% of the UK’s greenhouse-gas (GHG) emissions burden and 10-12% globally. Although there is a long-term declining trend from UK agriculture, the sector may account for a larger share of overall emissions in the future as other sectors reduce emissions. This POSTnote focuses on reducing GHG emissions from growing and storing arable and horticultural crops. ...

  • The problems with the arguments against GM crops

    New evidence shows that arguments against GM crops are unfounded, says Margaret Karembu. The year 2013 marked the 18th consecutive year of commercial cultivation of genetically modified organisms (GMOs) or now commonly referred to as biotech crops. And in just under two decades, the volume of ...

  • Nitrogen fixation of Sulla under Mediterranean conditions

    Sulla coronaria (L.) B.H. Choi & H. Ohashi (=Hedysarum coronarium L.) is a Mediterranean forage legume grown extensively in rainfed Italian environments. Here we report the field quantification of its seasonal and annual N fixation, using the 15N isotopic dilution (ID) method, the influence of various nonfixing reference species on these estimates, and the allocation of fixed N between the ...

  • Worms & Black Castings for an Abundance of Healthy Crops

    Earthworms are more than just good fishing buddies, they naturally incorporate organic material into the soil, increasing the amount of microbes, improving the health of the soil, and increasing plant productivity. Both worms and black castings from worms provide your garden or farm with a nutrient rich and robust environment, able to ...

  • One crop, two ways, multiple benefits

    Nitrogen fixation is one of the best examples of cooperation in nature. Soil microbes – naturally occurring bacteria in the soil – work with plants to pull nitrogen from the air. They turn the nitrogen into a form the plant is able to use. In return, the plant lets the microbes eat some of the sugars it makes. Faba beans (also called fava beans) are one example of plants that work ...

  • 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 ...

  • Enriching African soils key to boosting crop yields

    In African countries where farmers have access and can afford to buy fertiliser, there is a profound difference in agricultural yields, a feature in Nature notes. The red soil found across much of the continent is low in organic matter and key nutrients, and intensive farming in ...

  • Simulating switchgrass growth and development under potential and water-limiting conditions

    Anticipating a demand for switchgrass (Panicum virgatum L.) as a source for biofuel production, a crop simulation model of this crop can be a component of a biofuel decision support system. The objective of this effort was to develop and test a model for switchgrass, based on robust empirical relationships between plant behavior and the environment. The model simulates date of annual growth ...

  • Fate of indicator microorganisms under nutrient management plan conditions

    Nutrient management plans (NMPs) for application of wastewater from concentrated animal feeding operations are designed to meet crop water and nutrient requirements, but implicitly assume that pathogenic microorganisms in the wastewater will be retained and die-off in the root zone. A NMP was implemented on a field plot to test this assumption by monitoring the fate of several fecal indicator ...

  • Affordable Orlando Organic Fertilizers, Healthy Soil for Vegetables & Crops

  • Aquacrop—the FAO crop model to simulate yield response to water

    This article introduces the FAO crop model AquaCrop. It simulates attainable yields of major herbaceous crops as a function of water consumption under rainfed, supplemental, deficit, and full irrigation conditions. The growth engine of AquaCrop is water-driven, in that transpiration is calculated first and translated into biomass using a conservative, crop-specific parameter: the biomass water ...

  • Crop protection 2.0: reducing environmental impact in the EU Is it feasible?

    By 2023 all EU member states must be complying with more stringent guidelines related to Integrated Pest Management (IPM). “The essence of the new guideline is reducing the environmental impact of pesticides,” says Piet Boonekamp, manager of the Bio-interactions and Plant Health business unit at Wageningen UR. “In principle this European goal can be achieved, as has been shown ...

  • Growing cool-season crops could save California water

    Farmers base their decisions on which crops to grow based on a number of factors, including yield, water availability, and return on investment. In California, farmers most often decide to plant crops that thrive between March and October. Cool-season crops — those grown between October and June — may ultimately use less irrigation water according to new research from the University ...
