Abstract :

Microbial diversity in soil may be limited under natural conditions by inappropriate environmental factors such as: limited food resources, environmental and physical factors, tillage system and interspecies interactions prevent the occurrence or maintenance of the species in the environment. The aim of this work was to determinate structural biodiversity and functional microorganisms in in soil under long-term maize monoculture. The reaction of maize cultivated in perennial monoculture for the direct sowing was investigated and compared to full tillage monoculture and crop rotation full tillage cultivation in the following phases: six leaves, twelve leaves, flowering phase, before harvest and after harvest. Three objects were included into this research: maize cropped continuously monoculture - zero tillage, maize monoculture cropped continuously �?�?�?¢�?�?�?�?�?�?�?�? full tillage, crop rotation (spring barley, winter wheat, maize) �?�?�?¢�?�?�?�?�?�?�?�? full tillage. The evaluation of the structural biodiversity of the soil was based on the next-generation sequencing (NGS). The functional and metabolic profiles in soil were determined by Biolog EcoPlate System. The research methods used in this subject have contributed to a better understanding of genetic diversity and composition of the population of microorganisms in the soil environment under the influence of the changes that have taken in soil under long-term maize monoculture.

Biography :

Anna Ga�?�?�?�?zka is a head of the Department of Agricultural Microbiology at IUNG (since 2013). She is specialized in the evaluation of microbial diversity of soils associated with agricultural practice and environmental protection (research in molecular biology; evaluation of genetic differentiation and identification of microorganisms and characterization of metabolic profile of bacteria and fungi). She is participating in international and several national projects in IUNG, coordinating research project on biological activity and determination of microbial diversity of soil. She was a task manager in Aiming Project „Developing New system of tillage for sustainable agriculture” WND-POIG. 01.03.01-00-042/09 (2010-2013) – Determination of biological activity in soils and executor in projects: N305 080 32/2776 Evaluation of usefulness of Azospirillum spp. and Pseudomonas stutzeri inoculum in increasing of phytoremediation; project CZ.3.22/1.2.00/12.03445, Risk and benefits of application of exogenous organic matter on soil. Operational programme of cross-border co-operation Czech Republic – Poland 2007-2013. She was training of „Genomic of Nitrogen-Fixation Organisms” in 2008, Ghent, Belgium and participated in numerous courses and trainings in the field of molecular biology and microbiology. She works with NJF Nordic Association of Agricultural Scientists (keynote speakers on Seminar (483) 22-25.09.2015 Vezaiciai, Lithuania “Application of soil biological and biochemical parameters as indicator of soil health and fertility as influenced by different agrotechnical practices”). Member of Polish Microbiological Society since 2004 and author over 50 publications.
