Environmental Physics and Irrigation

  1. TANNY JOSEF e-mail Team:Dr. Shabtai Cohen
    Irrigation of protected crops during their initial growth using dynamic evapotranspiration estimates and its effect on yield
    Currently there is very little knowledge of irrigation requirements of protected crops based on the internal atmospheric water demand. Most irrigation practices use external meteorological conditions to estimate evapo-transpiration (ET) and a tabulated empirical factor based on field studies. Therefore, the actual water demand under cover is not considered. Moreover, most estimates are based on the Penman-Monteith model, which assumes full plant cover, which is hardly realized for row crops, and especially during their initial growth stages. The major goal of this research is to develop irrigation demand estimates for greenhouse crops during their initial growth, based on internal meteorological conditions and real time leaf area index (LAI), using dynamic ET models that are capable of partitioning between soil evaporation and plant transpiration.
    Education requirements
    Ph.D. in one of the following: Agricultural Sciences, Environmental Engineering, Atmospheric Sciences, Mechanical Engineering
    Scientific experience
    Processing and analysis of meteorological data from field experiments. Estimation of evapotranspiration by Penman-Monteith or a similar models.
    Skills
    Scientific programing in MATLAB. Data analysis in EXCEL. Technical skills and experience in installing and operating data loggers and meteorological sensors in the field. Reading and writing abilities in technical English.
  2. ROZENSTEIN OFERR e-mail Team:Prof. Eyal Ben-Dor (TAU)
    Developing remote and proximal sensing models to support precision agriculture (precision irrigation and fertilization)
    Spectral and temporal modelling of processes in agricultural crops: photosynthesis, water consumption, vegetative and reproductive development, with respect to the dynamics of water flow in the soil-plant-atmosphere continuum.
    Education requirements
    Ph. D. in: Earth and Atmospheric Sciences, Agricultural Sciences, Environmental Sciences, Geography, Engineering or a related field with emphasis on remote sensing.
    Scientific experience
    Experience handling remote sensing and GIS data, spatial – spectral – temporal analysis. Programming skills, extensive knowledge in signal / image processing, spectroscopy, machine learning, and statistics / geo-statistics are a plus.
    Skills
    Good English communication; Reading and writing of technical / scientific documents in English; Technical skills related to remote sensing and spectroscopy

    Water Flux Density Measurements (WFD) for Irrigation Control
    The main objective is to develop the heat-pulse method for measuring WFDs that are typical for agricultural system, in the range of 5 to 50 mm per day. Rootzone WFDs are correlated to the amount of irrigation and water uptake, and therefore have the potential for enabling management of irrigation based on real-time in-situ data. However methods for measuring WFD under variably saturated conditions are needed for this purpose. In this project: (1) the heat-pulse method will be developed using numerical and analytical models; (2) heat-pulse sensors will be constructed based on these results; and (3) tested in the laboratory under saturated and unsaturated conditions, in soil columns.
    Education requirements
    any of: hydrology; soil physics; mechanical engineering; environmental engineering
    Scientific experience
    conducting water experiments; scientific computing; math - calculus, linear algebra, differential equations
    Skills
    computing language (python, matlab, etc...), handy for planning and constructing experiments

Soil Chemistry, Plant Nutrition and Microbiology

  1. MINZ DROR e-mail Team:Eddie Cytryn
    Plant microbe interactions- plant microbiome
    Microorganisms are crucial for plant growth, development, health and nutrition. The plant microbiome structure and function is determined by many environmental parameters and it's study is currently among the "hottest" topics in science. We aim at studying the interactions between the plant and its microbiome in order to be able to control and design it according to our needs.
    Education requirements
    Microbiology, bioinformatics, molecular biology, microbial ecology
    Scientific experience
    the candidate should have experience in either microbiology (preferably environmental microbiology or microbial ecology), plant sciences or bioinformatics.
    Skills
    Independence yet ability to work in a team. Ability to read and write well in English. Willingness to work long hours when needed. Creativity, ability to think "out of the box". Experience in microbiome (metagenome/metatranscriptome/metabolome is preferable.
