Michael Raviv, Agricultural Research Organization, Newe Ya'ar Research Center, ISRAEL

How photoselective covers and pathogen-suppressive substrates can facilitate greenhouse Organic production?

Michael Raviv Prof. Michael Raviv completed his Ph.D. in plant physiology, in the Hebrew University of Jerusalem, in 1978. Since then he worked at the Newe Ya'ar Research Center as a scientist in the Dept. of Environmental Horticulture, until retirement at 2013. Between the years 1998 and 2006 he served as the Scientific Director of the Research Center. Between the years 1995-2013 he also served as a Professor at the Faculty of Agriculture, Rehovot at the Hebrew University of Jerusalem, where he taught a course on "Scientific issues in Organic Agriculture".

Most of his career, Prof. Raviv devoted his research to various issues related plant production is soilless culture. In 2008 he, together with a colleague from UC Davis – Prof. Heiner Lieth, published a book devoted to this subject, called "Soilless Culture – Theory and Practice" published Elsevier: (http://www.elsevier.com/wps/find/bookaudience.cws_home/713460/description#audience). Currently, and based on the request of the Publisher, they, together with a new co-editor, Dr. Asher Bar-Tal, are concluding a 2nd edition of this book.

Being recognized as one of the leading researchers in the field of plant production in substrates, Prof. Raviv was nominated on 2014 to serve as the Chair of the ISHS commission of Plant Substrates and Soilless Culture (http://www.ishs.org/plant-substrates-and-soilless-culture). In addition to the above he has edited/co-edited 7 books and proceedings, 17 book chapters and 103 scientifically-reviewed papers.

During the last 25 years, the focus of his research was the process of composting of organic wastes, to be served both as growing media and for soil application. He mostly concentrated on the production of compost suppressive against soil-borne diseases.

Another part of his research was devoted to photoselective covers of greenhouses, aimed at reducing the damage caused by foliar diseases. Six papers were published on this subject, some of them highly-cited.

Michael Spent sabbatical leaves at Cornell Univ., at the University of Minnesota, St. Paul and two sabbatical leaves at UC Davis.


Rodney Thompson, University of Almeria, Spain

Reducing Nitrate Leaching Losses from Vegetable Production in Mediterranean Greenhouses

Rodney Thompson Rodney (Rod) Thompson is from Melbourne, Australia where he studied Agricultural Science at the University of Melbourne. He completed a PhD at the Department of Soil Science at the University of Reading, England on N transformations associated with manure applied to land. He completed post docs at CSIRO, University of California, Davis and the USDA at Beltsville, Maryland in which he worked on N transformations in vegetable and cereal production, and decision support systems. He then moved to Almeria, Spain where he is now a Full Professor in the Department of Agronomy in the University of Almeria. In Almeria, together with Marisa Gallardo, he established a research program with vegetable crops grown in plastic greenhouses to optimise N and irrigation management in order to reduce nitrate leaching loss. This work is focussed on developing combined modelling (prescriptive management) and monitoring based management approaches (corrective management) for both N and irrigation. For N, various monitoring approaches are being studied including the use of proximal optical sensors (reflectance, fluorescence, chlorophyll measurement), sap and leaf analysis, and monitoring available N in the soil. For irrigation, various soil moisture sensors and stem diameter measurements have been evaluated. The research group of Rod and Marisa has worked with various crop simulation models (e.g. EU-Rotate-N) and has developed the VegSyst model, with minimal input requirements, for determining crop N uptake and ETc of greenhouse-grown vegetable crops. VegSyst has been incorporated into the user-friendly decision support system (VegSyst-DSS) to determine N and water requirements for the major vegetable species in south-eastern Spanish greenhouse production, which operates on Windows computers. In Almeria, the group has worked on regional studies of water use, drainage and nitrate leaching associated with greenhouse vegetable production. Since 2013, Rod has made nine invited presentations at diverse international conferences and research centres, has worked as an Associate Editor for Agricultural Water Management, and been the coordinator of the Working Group of Fertilisation and Irrigation of EUVRIN (European Vegetable Research Institute Network). He participated in the EIP-AGRI Focus Group on “Fertiliser efficiency - focus on horticulture in open fields”, and was a member of the Technical Working Group on Environmental Management Practice for the Agriculture, for European Commission, JRC-IPTS.


Yosepha Shahak, ARO TheVolcani Center, Bet-Dagan, Israel

Netting and Photoselective Netting: Friendly Solutions for High-Quality Production Together with Crop Protection

Yosepha Shahak Dr. Yosepha Shahak has four decades of academic and applicative research experience in bioenergetics, plant physiology and horticulture. She is a renowned expert in the area of plant-light interactions and its practical implications in agriculture. Her academic background includes PhD in biochemistry and photosynthesis from the Weizmann Institute of Science, Rehovot, Israel; EMBO fellowships in Germany; post-doctorate and sabbatical year in Brookhaven National Lab, NY, USA; and multiple sabbatical periods in UC-Davis, CA, USA. Following a Senior-scientist position at the Biochemistry Department, the Weizmann Institute of Science, Dr. Shahak assumed a research Prof. position at the Institute of Plant Sciences, ARO, the Volcani Center, where she established and headed a photo-biology research lab for 25 years. Dr. Shahak additionally served in numerous leading functions in Israel, including Head of Citriculture Department at the Volcani Center; Scientific Director of the Northern R&D Center (Mop-Zafon); the ARO Assistant Director for the Israel Regional Agricultural R&D Centers.

Dr. Shahak is well known for the developing of Photoselective Netting as a new concept in protected agriculture. Her pioneering studies of photoselective / light-dispersive netting in ornamental crops, vegetables and fruit trees, had established the beneficial functions of this technology in inducing photoselective physiological responses, alongside with its microclimate and protective functions.

Dr. Shahak was the head of the ISHS Photoselective Netting sub-working group for 8 years; the convener of international symposia and workshops (e.g. CIPA Conference on Plastics in Agriculture 2012; Photoselective Netting WS in IHC2006; Screens and Netting WS in IHC2014); and presented lectures and key-notes in many international meetings during the years.
