Abalimi baseMinnesota kungekudala baza kuba nenkqubo yolwazi oluqinileyo malunga neemeko zemozulu ukunceda ekwenzeni izigqibo zezolimo.
Abalimi abanakulawula imozulu, kodwa banokusebenzisa ulwazi malunga neemeko zemozulu ukwenza izigqibo. Abalimi baseMinnesota kungekudala baza kuba nenkqubo yolwazi eqinileyo abanokuyithatha kuyo.
Ngexesha leseshoni ka-2023, iNdlu yoWiso-mthetho yesizwe saseMinnesota yabela iSebe lezoLimo laseMinnesota i-$3 yezigidi kwiNgxowa-mali yaManzi acocekileyo ukuphucula uthungelwano lwemozulu yezolimo lwesizwe. Okwangoku iphondo linezikhululo zemozulu ezili-14 eziqhutywa yi-MDA kwaye ezingama-24 zilawulwa yiNorth Dakota Agricultural Weather Network, kodwa inkxaso-mali yesizwe kufuneka incede iphondo lifake ezinye iindawo ezininzi.
“Ngalo mjikelo wokuqala wenkxaso-mali, sinethemba lokufaka izitishi zemozulu ezimalunga nama-40 kwiminyaka emibini ukuya kwemithathu ezayo,” utshilo uStefan Bischof, ingcali yamanzi ye-MDA. “Injongo yethu ephambili kukuba nesitishi semozulu esikumgama weemayile ezingama-20 ukusuka kuninzi lwemihlaba yezolimo eMinnesota ukuze sikwazi ukubonelela ngolwazi lwemozulu lwasekuhlaleni.”
UBischof uthi ezi ndawo ziza kuqokelela idatha esisiseko efana nobushushu, isantya somoya kunye necala, imvula, ukufuma, indawo yombethe, ubushushu bomhlaba, imitha yelanga kunye nezinye iindlela zokulinganisa imozulu, kodwa abalimi nabanye baya kukwazi ukufumana ulwazi oluninzi.
IMinnesota isebenzisana neNDAWN, elawula inkqubo yezikhululo zemozulu ezimalunga nama-200 kulo lonke elaseNorth Dakota, eMontana nakwintshona yeMinnesota. Inethiwekhi yeNDAWN yaqala ukusebenza ngokubanzi ngo-1990.
Musa ukuyila kwakhona ivili
Ngokusebenzisana ne-NDAWN, i-MDA iya kukwazi ukusebenzisa inkqubo esele yenziwe.
“Ulwazi lwethu luza kufakwa kwizixhobo zabo zezolimo ezinxulumene nemozulu ezifana nokusetyenziswa kwamanzi ezityalo, imihla yokukhula, imodeli yezityalo, ukuqikelela izifo, ishedyuli yokunkcenkceshela, izilumkiso zokutshintsha ubushushu bezixhobo zokusebenza kunye nenani lezixhobo ezahlukeneyo zezolimo abantu abanokuzisebenzisa ukukhokela izigqibo zezolimo,” utshilo uBischof.
“I-NDAWN sisixhobo sokulawula umngcipheko wemozulu,” ucacisa uMlawuli we-NDAWN uDaryl Ritchison. “Sisebenzisa imozulu ukunceda ukuqikelela ukukhula kwesityalo, njengesikhokelo sesityalo, isikhokelo sezifo, ukunceda ekumiseleni ukuba izinambuzane ziza kuvela nini - izinto ezininzi. Ukusetyenziswa kwethu kukwadlula kakhulu ezolimo.”
UBischof uthi uthungelwano lwemozulu yezolimo eMinnesota luza kusebenzisana noko sele kuphuhlisiwe yi-NDAWN ukuze kusetyenziswe izixhobo ezingaphezulu ekwakheni izitishi zemozulu. Ekubeni iNorth Dakota sele ineteknoloji kunye neenkqubo zekhompyutha ezifunekayo ukuqokelela nokuhlalutya idatha yemozulu, bekusengqiqweni ukugxila ekufumaneni izitishi ezininzi.
I-MDA ikwinkqubo yokuchonga iindawo ezinokubakho zezikhululo zemozulu kwilizwe laseMinnesota elisemaphandleni. URitchison uthi iindawo zifuna kuphela indawo engama-square-yard ezili-10 kunye nendawo yenqaba ende engama-30 eemitha. Iindawo ezikhethwayo mazibe zithe tyaba, kude nemithi kwaye zifikeleleke unyaka wonke. UBischof unethemba lokufaka ezili-10 ukuya kwezili-15 ehlotyeni.
Impembelelo ebanzi
Nangona ulwazi oluqokelelwe kwizikhululo luza kugxila kwezolimo, ezinye izinto ezifana neearhente zikarhulumente zisebenzisa ulwazi ukwenza izigqibo, kuquka nokuba kufuneka zibeke nini okanye ziphakamise nini imiqathango yobunzima bendlela.
UBischof uthi umzamo wokwandisa uthungelwano lwaseMinnesota ufumene inkxaso ebanzi. Abantu abaninzi babona ukubaluleka kokuba nolwazi lwemozulu lwasekuhlaleni luncede ekukhokeleni izigqibo zezolimo. Ezinye zezo zinketho zokulima zinefuthe elikhulu.
“Sinenzuzo kubalimi kwaye sinenzuzo nakwimithombo yamanzi,” utshilo uBischof. “Ngemali evela kwi-Clean Water Fund, ulwazi oluvela kwezi zikhululo zemozulu luya kunceda ukukhokela izigqibo zezolimo ezingazuzisi nje kuphela umlimi kodwa zinciphise nempembelelo kwimithombo yamanzi ngokunceda abo balimi basebenzise ngcono izixhobo zezityalo kunye namanzi.
"Ukuphucula izigqibo zezolimo kukhusela amanzi angaphezulu komhlaba ngokuthintela ukuhamba kwezibulali zinambuzane ezinokutsalela emanzini angaphezulu akufutshane, ukuthintela ukulahleka komgquba kunye neekhemikhali zezityalo xa zibaleka ziye emanzini angaphezulu komhlaba; ukunciphisa ukuvuza kwe-nitrate, umgquba kunye neekhemikhali zezityalo emanzini angaphantsi komhlaba; kunye nokwandisa ukusetyenziswa kwamanzi okunkcenkceshela."
