The Püspökladány Salinization Experimental Yard was founded on 1 October 1924 with Károly Kaán's ambition to elaborate methods of tree planting on lowland areas, especially saline or deep regions. The idea of improving saline soils was not a new one at this time but systematic research was not started yet. In 1911, Gyula Roth proposed a plan for establishing a yard of this Pladany1type that was supported by Jenő Vadas. However, the events of World War I   prevented the realization of the plan. In 1920, János Tuzson suggested that they plant trees on the areas of Püspökladány Religious Foundation's Manor to the North from the chief railway. He believed that when planting trees around heavily salinated woodlots, better grass yield can be achieved, so their management might better benefit from that. Today, this idea is justified by the better grass yield and the species composition of the surrounded meadows. After that, in the meeting in April 1922, the Alföld (the Great Plain) Afforestation Consultancy put on agenda the development of a new experimental plan. In order to start works on the yard, Károly Kaán assigned Pál Magyar forest engineer to assist János Tuzson, and József Galambos forest engineer to assist Elek Sigmund for a one-year study period. At the beginning, the experimental yard operated under the leadership of Pál Magyar as a unit of Debrecen Forest Management. Between 1927-44 it belonged to the Central Forest Experimental Station. From 1927 to 1928, the Head of the yard was József Galambos, then, from 1928 until 1944, Elemér Tury conducted the experiments. After 1945, the Debrecen Forest Management took over the supervision of the yard as a forest district. It became again managed by Elemér Tury from 1 February 1953 and was operating as FRI Experimental Station of Tree Planting on Saline Areas. It has been working as the FRI Tiszantul Experimental Station since 1963, under the leadership of Béla Tóth until 1985, that of Imre Kapusi (1985-93), Béla Tóth (1994-1995), and Imre Csiha (1995-). In addition to the reasearch on tree planting on saline areas, the Station operates a poplar reasearch system of 550 acres that is, netting the whole Alföld (Great Plain), trying to solve questions of variety selection and those of growing technology. Research is also focusing on black locust improvement that is, based on selection, attempting to increase the genetic reserve of Hungarian black locust growing. Technonlogical research is carried out on an area of more than 170 hectares in order to give guidelines to forest practice. In our provenance tests on Hungarian ash, we want to find out more about the ecological tolerance of this species of great value. Russian olive and wild pear selection will increase the genetic value of admixed species that occur in forest communities of the Alföld. Gene preservation research on black poplar is aimed at preservation of the still occurring specimen on their habitat. Experiments are also carried out in order to preserve and propagate them in nurseries. Selection of trees and shrubs in the frame of tree planting on Alföld is carried out in the arboretum that belongs to the Station. Results will improve the ecological stability, game bearing capacity, and the economic value of these forests. The greatest achievement of our work is the domestication of Siberian elm (Ulmus pumila 'Puszta') that, because of its drought tolerance and resistance to Duch elm desease, may play a significant role in the afforestation of Alföld. The evaluation of salinization research is the most important task of the Station. Since the Farkassziget was declared a protected area, we have been investigating whether the methods of forest management that are based on natural processes can be applied to forest steppe climate. We pay a special attention to private forestry. Research on selection of species for plantations and, within that, that of energy forests, technology, and development, putting the results into practice as soon as possible are of great importance.
