Název v původním jazyce

Availability of soil nitrogen mediated by rhizosphere

Popis výsledku v původním jazyce

Understanding to the relationships and interactions between the soil, plants and soil organisms in the rhizosphere is the most important step in understanding to the essence of soil fertility. According to the rhizosphere concept, firstly formulated by Lorenz Hiltner in 1904, rhizosphere is an area of active interchange between plants and soil bacteria, where photosynthate fuels microbial growth and activity, ultimately resulting in the stimulation of specialized microorganisms. In extremely heterogeneous environment such as soil act bacterial populations co-operatively and do so by the process, known as quorum sensing (QS). Immediate capturing of available nutrients from the soil solution by microorganisms is followed by their rapid growth and activity. Soon are the current sources of available N exhausted. Microorganisms respond to this pulse by production of extracellular enzymes for the mineralization of insufficient nutrients from poorly available part of soil organic matter (SOM). Despite the initial uptake of N mineralized from SOM by microorganisms, their much shorter life cycle compared with that of plant roots leads to the release of acquired N back into the soil; this mineral N is then available for root uptake in higher amounts than at the beginning. Presented concept of soil fertility stemming from the interactions in the environment surrounding plant roots is by the intensive agriculture unfortunately overlooked.
