Ongororo ichangoburwa yakaburitswa mupepanhau rePotato Research inojekesa zvinokonzeresa shanduko yemamiriro ekunze pakurima mbatatisi muSouth Korea. Vatsvagiri kubva kuLeibniz Center for Agricultural Landscape Research (ZALF) neBrandenburg University of Technology Cottbus vakabatana pachidzidzo ichi kuti vaongorore mhinduro dzembatatisi dzechirimo nezhizha pakuchinja kwemamiriro ekunze mudunhu.
Dr. Yean-Uk Kim, munyori anotungamira wechidzidzo ichi uye nyanzvi yezvesainzi kuZALF, anoburitsa zvakawanikwa zvinoratidza kugona kwe CO2 fertilization mhedzisiro yekudzikisa kushata kwekukwira kwematembiricha pambatatisi dzechirimo. Nekugadzirisa nguva dzekudyara, izvi zvinogona kuwedzera goho rembatatisi yechirimo nekusvika 60%. Iyo CO2 fertilization mhedzisiro inoreva chiitiko apo kukwirisa kwemuchadenga CO2 mazinga anovandudza photosynthetic kushanda kwezvirimwa, zvichikonzera kukurumidza kukura uye kuwedzera kubereka.
Chidzidzo ichi chinosimbisa kukosha kwekutora mhando dzembatatisi dzinoshingirira kumamiriro ekunze senzira yekugadzirisa matambudziko emunguva yemberi. Vatsvagiri vanokurudzira kudyara kwekutanga kwembatatisi dzechirimo mumamiriro ekunze ari kushanduka uye kusimbisa kukosha kwekuberekesa marudzi anoshivirira kupisa mumamiriro ekunze akanyanya. Kune mbatatisi dzezhizha, kuwedzera kushivirira kune tembiricha yakakwira inobuda seyakanyanya kutariswa nzvimbo, zvisinei nekufungidzirwa kwekuchinja kwemamiriro ekunze.
Dr. Kim vanosimbisa kukosha kwezviwanikwa izvi mukugadzira maitiro ekurima anoenderera mberi uye kuve nechokwadi chekuchengetedza chikafu kwenguva refu mudunhu. Ongororo iyi inoratidza kuti musanganiswa wemhando dzekurima nemamiriro ekunze ungabatsira sei mukugadzira nzira dzekugadzirisa mamiriro ekunze ari kusanduka.
Tichifambira mberi, boka rekutsvakurudza rinoronga kuongorora kukanganisa kwekuwedzera kwezviitiko zvemamiriro ekunze zvakanyanya, izvo zvisina kutaurwa muchidzidzo chezvino. Nekuwana ruzivo rwematambudziko anokonzerwa nekushanduka kwemamiriro ekunze-kunokonzerwa nekunyanyisa kwemamiriro ekunze, vatsvakurudzi vane chinangwa chekupa mamwe maitiro akarongedzerwa uye anobudirira ekugadzirisa kutsigira varimi mukufamba kuoma kwemamiriro ekunze ari kubuda.
