The currently led researches in the soil microbiology as well as those conducted by the numerous scientists worldwide, particularly by those in genetic engineering, have emphasized the potentials and an indispensability of altering the existing farming production being practiced as yet. The basic principle of the new farming technology ought to be nourishing soil, as a source of plant life and of the biologically active environment, and not nourishing plants. This technology is mainly oriented to exerting biological soil activity to sustain and to further increase soil fertility. The research results have highlighted the existence of effective methods in acting on the microbe soil community when microbiologically managing the biochemical processes in keeping up such potential and when effectively increasing soil fertility via protecting and improving agroecosystem in finding solutions to protein deficit.

ULOGA MIKROORGANIZAMA U UNAPREĐENJU I ZAŠTITI  AGROEKOSISTEMA, KAO I U REŠAVANJU BELANČEVINSKOG DEFICITA

Naša istraživanja u oblasti zemljišne mikrobiologije, kao i istraživanja velikog broja naučnika sveta u ovoj oblasti, a posebno u oblasti genskog inženjeringa, ukazuju na mogućnost i potrebu određene promene postojeće prakse poljoprivredne proizvodnje. Osnovni princip nove tehnologije poljoprivredne proizvodnje treba da bude – hraniti zemljište, kao izvor života biljaka i biološki aktivnu sredinu, a ne biljke. Ova tehnologija je usmerena, uglavnom, na podsticanje biološke aktivnosti zemljišta pa, prema tome, na održavanje, a zatim i na povećanje plodnosti zemljišta. Rezultati istraživanja ukazuju na postojanje efektivnih metoda uticaja na mikrobne zajednice zemljišta, koje omogućavaju mikrobiološko regulisanje biohemijskih procesa u pravcu očuvanja potencijalne i povećanja efektivne plodnosti zemljišta, unapređenja, zaštite agroekosistema i rešavanje belančevinskog deficita.

Ključne reči: agroekosistem, belančevine, deficit, mikroorganizmi, unapređenje, zaštita.
