  • Method for irrigation scheduling based on soil moisture data acquisition

    The water requirements of crops are dependent on evapotranspiration (ET), soil chemistry, and the crop’s maximum allowable depletion (MAD). Direct measurements of root zone soil moisture, water application along with published ET values and soil textures, can be used in a soil water balance model that can significantly optimize irrigation efficiency. Over the past five years, advancements in ...

  • Group method of data handling (GMDH) in modelling of growth dynamics of trees irrigated with wastewater

    This paper describes the formulation and analysis of growth dynamics models for trees irrigated with wastewater. The models can be used to obtain the characteristics of a species, depending on treatment conditions and climate factors, at all stages of growth. The experiments were carried out at the University of Patras to identify the characteristics (height rate and mortality) of the forest tree ...

  • Group method of data handling (GMDH) application for modelling of mechanical properties of trees irrigated with wastewater

    Experiments have been carried out to identify the mechanical properties of trees irrigated with wastewater, as well as mathematical modelling of measurement results via the group method of data handling (GMDH) method. Eucalyptus trees were cultivated and irrigated with processed wastewater from a treatment plant. Characteristics of wood quality (axial compression and bending, etc.) were measured ...

  • Digging for data on Africa’s climate future

    The cardboard box is covered with a layer of dust so thick it must have been tucked away in this Kenyan basement for decades. The researcher wipes off the dust and rummages through the papers stored inside by someone long since retired. Sheet after sheet of neatly typed paper emerges, the faded rows of numbers detailing rainfall, temperature and wind speed. In a way, the researcher is hunting for ...

  • Data Logger the size of a credit card

    Negligent handling of temperature sensitive goods can have fatal consequences. Of course it is advantageous to control temperatures, however temperature data loggers of the past were often bulky and unmanageable. Now there is a data logger which has been reduced to the size of a credit card. Goods are not always treated gently during transportation. Shipping businesses are increasingly under ...

  • A Moment Matching Approach for Generating Synthetic Data

    ABSTRACT Synthetic data are becoming increasingly important mechanisms for sharing data among collaborators and with the public. Multiple methods for the generation of synthetic data have been proposed, but many have short comings with respect to maintaining the statistical properties of the original data. We propose a new method for fully synthetic data ...

  • Pesticide decay in turf: A review of processes and experimental data

    Received for publication November 26, 2007. Decay rates are central parameters in modeling pesticide fate and transport in the environment. Pesticide decay is usually modeled as a first-order process, and variations in half-life can have significant impacts on model predictions. Decay rates for the foliage and thatch components of turf are scarce, and most simulation efforts must resort to values ...

  • Assessing The Health of Marine Ecosystems Through Fisheries Data

    Ecosystem Health Assessment (EHA) started to be applied in environmental management in the late 80s. Since then, a considerable number of ecological indicators have been applied for EHA. Jørgensen et al. (2005a) have classified these indicators into eight levels corresponding to: indicators based on specific ...


  • India needs micro-level data for climate action

    India needs micro-level scientific assessment at the state, district and village levels for effective planning and implementation of measures to combat climate change, a national workshop has highlighted. The workshop on climate-resilient ...

  • Waterquality in irrigation canals and boreholes - Greece

    Background Kavala is located in the North East of Greece, 680 km from the capital Athens. The population of the prefecture of Kavala is around 85,000 people. The River Nestos which flows through this prefecture is very important for the agriculture of the area. To allow for a fair distribution of the water for irrigation purposes, a number of Boreholes and canals have been established. The ...

  • Implementing participatory irrigation management in Thailand

    Participatory Irrigation Management (PIM) was formally adopted in Thailand in 2004. The involvement of farmers in water management decision making is necessary to meet the implementation challenges of this initiative. As such, the research presented in this paper considered the level of farmer involvement in water management and decision making, and the lessons learned by both government ...

  • CIRAS-2 Export function-simplified data format with numerical and graphical data views

    Perhaps some of the most exciting moments for CIRAS-2 Portable Photosynthesis System users come when the time arrives to view meaningful data sets. What many new users will not realize is that they have the option of viewing these data in two formats: raw CIRAS-2 format (.dat) and a much streamlined Export format (.tab). Both formats easily and automatically import and parse into spreadsheet ...

  • Plan B 4.0 by the numbers - data highlights on the global food supply

    World agriculture today faces pressure from many sources. On the production side, the amount of unused arable and worldwide has dwindled. Overworked soils are becoming eroded and degraded, and overpumped aquifers are being depleted. Meanwhile, as the global population grows and increasing biofuel production converts grain into fuel for cars, demand for food continues to climb. In Chapters 2 and 9 ...
