Mikrobna ekologija agroekosistemov

Opis predmeta

Vloga mikroorganizmov pri kroženju elementov (C, N, S, P, Fe, Mn, O, H, Si, Ca, Hg, Cr, Pb, Zn, Cu).
Biorazgradnja rastlinskega materiala.
Mikrobna ekologija rizosfere in filosfere
Simbiontske interakcije mikrooroganizmov in rastlin (mikoriza, fiksacija dušika).
Vloga mikrobnih združb v različnih agroekosistemih.

Cilji in kompetence

Študent spozna vlogo mikroorganizmov pri delovanju različnih agroekosistemov. Mikroorganizme zna izkoriščati v proizvodne namene.

Metode poučevanja in učenja

Predavanja po posameznih sklopih.

Problemsko voden seminar prilagojen potrebam posameznega študenta. Seminar lahko študent v dogovoru z nosilcem opravi teoretično ali praktično v laboratoriju.

Predvideni študijski rezultati

Študent razume funkcioniranje sistema rastlina-mikrob v rizosferi in filosferi.

Razume vlogo mikroorganizmov pri biorazgradnji, kroženju snovi in energije v ekosistemu in pomenu le tega za prehrano rastlin. V podrobnostih razume mikorizo in biološko fiksacijo in ju zna izrabiti v praksi.
