Mbolea
& quot; Idadi ya watu wasio na lishe ulimwenguni inabaki kuwa kubwa bila kukubalika karibu milioni 925. Maswala ya usalama wa chakula ulimwenguni yapo sasa, na ni ya kutia wasiwasi kutazamia mbele wakati idadi ya watu ulimwenguni inatarajiwa kuongezeka kwa karibu 35% katika kipindi cha miaka 40 ijayo. Pato la kilimo litahitaji kuongezeka kwa kiasi kikubwa kutoshea idadi ya watu inayoongezeka. Ongezeko kubwa linatarajiwa kutoka kwa kuzalisha zaidi kwenye shamba lililopo (kwa mfano, kuongezeka), ingawa shamba mpya litahitajika. Kuongeza mavuno ya mazao na kuziba pengo kati ya mazao halisi na yanayoweza kupatikana inaweza kupatikana kwa utekelezaji na maendeleo ya mazoea na teknolojia anuwai, pamoja na mazoea ya usimamizi wa virutubisho na teknolojia za mbolea. Tathmini ya tafiti za muda mrefu imeonyesha kuwa asilimia wastani ya mavuno yanayotokana na pembejeo za mbolea kwa ujumla yalitoka karibu 40 hadi 60% katika hali ya hewa ya joto (USA na England), na ilikuwa ya juu zaidi katika nchi za hari. Vitu vyote vinavyozingatiwa, mbolea isiyo ya kawaida ina jukumu muhimu katika usalama wa chakula ulimwenguni, lakini ni lazima itambulike kuwa mavuno mengi ni katika mifumo mingine matokeo ya kutumia vyanzo vya virutubishi visivyo vya kawaida. Kupitishwa kwa chanzo cha virutubisho-haki cha kanuni za 4R kwa kiwango sahihi, wakati unaofaa, na mahali pazuri-kusaidia kuhakikisha matumizi sahihi ya rasilimali za virutubisho na tija iliyoboreshwa. & Quot;
