САЖЕТАК:

U poslednje vreme, svedoci smo kontinuiranog rasta cena fosfornih đubriva koja postaju sve manje dostupna, naročito u zemljama u razvoju. Pored toga, mala pokretljivost fosfora u zemljištu i njegova imobilizacija u oblike nedostupne biljkama doprinose manjoj efikasnosti fosfornih đubriva primenjenih preko zemljišta. Da bi se ovi problemi umanjili, teži se pronalaženju alternativnih rešenja za snabdevanje višegodišnjih krmnih leguminoza fosforom, koja bi u budućnosti mogla doprineti ekonomičnom i efikasnom rešavanju problema nedostatka fosfora u biljkama. Jedno od takvih rešenja je folijarno đubrenje. Međutim, danas se radi i na oplemenjivanju biljaka u pravcu stvaranja genotipova sa boljom arhitekturom korena. Takođe, radi se na selekciji genotipova koji mogu da koriste fosfor iz teško rastvorljivih fitiata, kao i selekciji u pravcu intenziviranja simbioze sa mikoriznim gljivama koje doprinose mobilnosti fosfora u zemljištu.
