NEW OPPORTUNITIES AND CHELLENGES FOR SUSTAINABLE LAND MANAGEMENT (SLM)
Published August 21, 2020
31-37

Special literature sources have been discussing the concept of sustainability and the feasibility options only for about three decades. Sustainable development has several definitions; it is defined both in narrow and wider sense. The definition of sustainability is regarded inevitable because the sustainability of agriculture can be interprete...d only within this fixed conceptual framework. Our study is primarily dealing with issues of sustainability in farming practices being peculiar to countries, regions of the European Union. In frames of current research, we are providing the analysis of the ability to produce value added within the agricultural sector, the intensity of farming, the non-renewable external input use, farm structure as well as the European-level relations being directed towards the preservation of land productivity.

Application of bioeffector soil inoculation method development in a pot experinment with tomato
Published August 6, 2020
183-189

Fertilizers, 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 devel...op 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.
