International Agrophysics Vol. 3. No. 4. 1987 [antikvár]

GUEST EDITORIALThis is a "Debrecen issue" of the journal. In Debrecen there is a long tradition of physics and today Debrecen is a fairly active centre of physical research activities in Hungary.As is well-known, the laws and methods of physics are equally valid for the whole of Nature: in the microcosm and in the Universe, in inorganic matter and in biological tis-sues. Thus, it is not a surprise that they are of significance in theprocessesandphenomena in soii, in plants and in animals which are important from the point of view of agro-sciences.The term "agrophysics", however, appeared relatively late, in comparison, e.g. with agrochemistry. It should be mentioned in the introduction of a Debrecen issue of this journal that in Hungary the first committee to deal with the organization and surveying of the research in this field was förmed within the framework of the Debrecen Section of the Hungárián Academy of Sciences in 1981/ although such investigations were alsó performed in institutions located in other parts of the country. It is for this reason that the activities of this committee, initiated by the recently deceased Dr. B. Schlenk, were of a national character up to this year, when an Agrophysics Committee began to operate within the framework of the Hungárián Academy of Sciences in Budapest.In this issue of International Agrophysics, the contributions are primarily from the Agricultural University of Debrecen and from other institutions in Debrecen, e.g. the Institute of Nuclear Research of the Hungárián Academy of Sciences (ATOMKI), Kossuth University, The Tobacco Research Institute. At the same time, however, there are works carried out in cooperation and so the authors are in these cases from institutions in quite different parts of the country, nameiy from the Research Centre of the Seed Company, Nyíregyháza; the Cereal Research Institute, Szeged; the Research Institute of Debrecen Agricultural University, Karcag.
