Description

Ohranjanje rodovitnosti tal je temeljna zaveza človeštva, saj saj tla omogočajo pridelavo hrane. Mikroorganizmi imajo pri tem prav posebno pomembno vlogo, saj omogočajo kroženje hranil in so zaradi tega nepogrešljiv partner rastlinam. Velja pa tudi obratno. Največ mikrobne aktivnosti je vezano na rizosfero, to je tisto območje v tleh, kjer se čuti vpliv rastlinskih korenin in delovanja mikroorganizmov. V prispevku bodo prikazani različni načini, kako v rizosferi prihaja do teh interakcij.


Soil fertility is the fundamental characteristic of soil that supports plant life and enables food production. Microorganisms are indispensable in maintaining soil fertility due to their ability to sustain nutrient cycling. The majority of soil microbial activity is located in rhizosphere, a narrow region of soil that is directly influenced by root secretions and associated soil microorganisms. In the article many different ways how microorganisms and plants interact in the rhizosphere will be discussed.
