Application of bioeffector soil inoculation method development in a pot experinment with tomato
183-189Views:113Fertilizers, pesticides, soil disinfectants and other agrochemicals enormously have increased the agricultural productivity recently. Beside the well-accepted positive yield-effects, however, the structural soil-degradation, acidification, decrease of soil life and soil health is also known. Alternative technologies are urgently needed to develop for the sustainable agri-, horti-, viti- and silvicultural productions. The beneficial microorganisms, used as biofertilizers, biopesticides and/or soil-vitality products can reduce those disorders; therefore their use is increasing simultaneously. Bioeffector (BE) products, containing vital strains of the beneficial microorganisms might improve the qualitative and quantitative properties of the plants. The effects of BE1 - Trichoderma harzianum T-22; BE2 - Pseudomonas sp.; BE3 - Bacillus amyloliquefaciens Rhizovital 42 F1 were tested in large-pot experiment of using tomato (var. Mobil) in 4 replicates. The BE-s were applied according to the instructions of the producers, in 1 step with the sewing. Before the emergence of the tomato seedlings the BE products was enhancing primarily the growth of the weeds, which is known to develop much faster, than the host. Among the tested bioeffectors, the BE 3, known to enhance P-uptake proved to be the most efficient, both as single and as combined inoculums. Result was comparable with the fertilizer (triple-superphosphate) addition. Study has shown, that the application of BE products might be accompanied more seriously with the used agricultural technology and the physiological properties of the living biofertilizer strains. A second inoculation after the seed emergence and/or the plantation could be highly suggested mainly with BE 3, which might mobilize the hardly available phosphorous in the soil.

Studies on the Land-Use History of Kétsoprony Village in the 19th-20th Century with Focus on the Changes of the Biotope Network
332-340Views:119The biotope network has an important role in the case of intensive agricultural landscapes. Our aim was to examine the history of land-use of an intensively managed area – as Kétsoprony village – in the Alföld (Great Hungarian Plain) region and to study the changes in the biotope network, especially the tree rows in time. The biotope network and mainly the tree rows may be importance from the aspect of nature conservation because land use has been dominated by arable lands in the research area for centuries. We have identified the main stages of structural changes by studying historical maps and considering quantitative and qualitative features. We have found that the rate of arable lands was continuously growing while the length of tree rows was decreasing in the 19-20th centuries.
