  • A method of calibration and variance analysis with respect to the Penman-Monteith equation for the Turc, Hargreaves and Abtew potential evapotranspiration models

    Introduction: The full ASCE/FAO-56 Penman-Monteith evapotranspiration (PM-ET) equation and crop coefficients are often employed for irrigation scheduling of open-field crops. To obtain PM-ET derived water-use figures requires access to full weather station datasets, which includes radiation, air temperature, wind-speed, and relative humidity measurements. Over the years there have been many ...

  • An Instrumented Rhizotron to Investigate the Root Growth In Wheat - Case Study

    There has been much recent interest in modifying root system properties to overcome the effects of soil abiotic stress on crop growth and yield (Lynch 2007; Ghanem et al. 2011). Plant root systems are usually exposed to heterogeneous environmental conditions due to vertical differences in soil moisture and strength. Strong subsurface layers of soil can confine root systems to shallower soil ...

  • Irrigation Application Management

    The Irrigation Applications management takes all measurements of the inlet discharge and pressure at the pivot point and pivot end. Especially when the ground is uneven, where we take readings at the highest point. Preferably, this pressure value should be at least 5 PSI higher than the rated value of the pressure regulator, to ensure safety and proper operation, as the regulator must be ...

  • The Accurate Way to Soil Moisture Sensing

    Why Acclima soil moisture sensor technology is superior in terms of accuracy and cost Permittivity is a property of matter and is well characterized especially for materials that are electrically non-conductive. Water in its pure form is non-conductive. Permittivity quantifies the charge holding capacity for insulating materials. It is the ratio of stored electric charge to an applied ...

  • Modelling water requirements of greenhouse spinach for irrigation management purposes

    Estimating water requirements of plants cultivated in greenhouse environments is crucial, both for the design of greenhouse irrigation systems and the improvement of irrigation scheduling. Spinach is one of the main vegetables sold as ‘ready-to-eat’ bagged produce; it is very sensitive to water stress and thus requires accurate irrigation. In this work, a water balance model simulating the ...
