Amafama aseMinnesota kungekudala aya kuba nenkqubo eyomeleleyo yolwazi malunga neemeko zemozulu ukunceda ukwenza izigqibo ze-agronomic.
Abalimi abakwazi ukulawula imozulu, kodwa banokusebenzisa ulwazi malunga neemeko zemozulu ukwenza izigqibo. Amafama aseMinnesota kungekudala aza kuba nenkqubo eyomeleleyo yolwazi ekuza kutsalwa kuyo.
Ngexesha leseshoni ye-2023, iNdlu yoWiso-mthetho yaseMinnesota yabelwe i-3 yezigidi zeedola ukusuka kwiNgxowa-mali yamanzi acocekileyo kwiSebe lezoLimo laseMinnesota ukunyusa inethiwekhi yemozulu yezolimo. Urhulumente okwangoku unezikhululo zemozulu ezili-14 eziqhutywa yi-MDA kunye ne-24 elawulwa yi-North Dakota Agricultural Weather Network, kodwa inkxaso-mali karhulumente kufuneka incede urhulumente afake iindawo ezininzi ezongezelelweyo.
“Ngalo mjikelo wokuqala wenkxaso-mali, sinethemba lokufaka izikhululo zemozulu ezimalunga nama-40 kwiminyaka emibini ukuya kwemithathu ezayo,” utsho uStefan Bischof, isazi se-hydrologist eMDA. "Injongo yethu yokugqibela kukuba nesikhululo semozulu phakathi kweekhilomitha ezingama-20 kwiindawo ezininzi zezolimo eMinnesota ukuze sikwazi ukubonelela ngolwazi lwemozulu yendawo."
UBischof uthi iziza ziya kuqokelela idatha esisiseko efana nobushushu, isantya somoya kunye nomkhombandlela, imvula, ukufuma, indawo yombethe, ubushushu bomhlaba, imitha yelanga kunye nezinye iimetriki zemozulu, kodwa amafama kunye nabanye baya kukwazi ukubhikica kuluhlu olubanzi kakhulu lolwazi.
I-Minnesota isebenzisana ne-NDAWN, elawula inkqubo malunga nezikhululo zezulu ze-200 kulo lonke elaseNyakatho Dakota, eMontana nasentshonalanga yeMinnesota. Inethiwekhi ye-NDAWN yaqala ukusebenza ngokubanzi ngo-1990.
Musa ukuphinda uqambe ivili
Ngokusebenzisana ne-NDAWN, i-MDA iya kuba nakho ukungena kwinkqubo esele iphuhlisiwe.
"Ulwazi lwethu luya kuhlanganiswa kwizixhobo zabo ze-ag ezinxulumene nemozulu ezifana nokusetyenziswa kwamanzi kwezityalo, iintsuku zedigri ezikhulayo, imodeli yezityalo, ukubikezelwa kwezifo, ukucwangciswa kokunkcenkceshela, izilumkiso ze-inversion zeqondo lokushisa kubafaki-zicelo kunye nenani lezixhobo ze-ag ezahlukeneyo ezinokusetyenziswa ngabantu ukukhokela izigqibo ze-agronomic," uBischof uthi.
"I-NDAWN sisixhobo sokulawula ingozi yemozulu," uMlawuli we-NDAWN uDaryl Ritchison uyachaza. "Sisebenzisa imozulu ukunceda ukubikezela ukukhula kwezityalo, ukukhokelwa kwezityalo, ukukhokelwa kwezifo, ukunceda ukufumanisa ukuba izinambuzane ziza kuvela nini - izinto ezininzi. Ukusetyenziswa kwethu kudlulela ngaphaya kwezolimo."
U-Bischof uthi inethiwekhi yemozulu yezolimo yaseMinnesota iya kusebenzisana noko i-NDAWN sele iphuhlisiwe ukuze kubekwe izixhobo ezingakumbi ekwakhiweni kwezikhululo zemozulu. Ekubeni iNorth Dakota sele ineteknoloji kunye neenkqubo zekhompyutheni ezifunekayo ukuqokelela kunye nokuhlalutya idatha yemozulu, kwakunengqiqo ukugxila ekufumaneni izikhululo ezininzi.
I-MDA ikwinkqubo yokuchonga iziza ezinokubakho kwizikhululo zemozulu kwilizwe lefama laseMinnesota. U-Ritchison uthi iziza zifuna kuphela malunga ne-10-square-yard footprint kunye nesithuba malunga ne-30-foot-tall tower. Iindawo ezikhethwayo kufuneka zibe mcaba, kude nemithi kwaye zifikeleleke unyaka wonke. U-Bischof unethemba lokufumana i-10 ukuya kwi-15 efakwe kweli hlobo.
Impembelelo ebanzi
Ngelixa ulwazi oluqokelelweyo kwizikhululo luza kujoliswa kwezolimo, amanye amaziko afana namaziko karhulumente asebenzisa olu lwazi xa esenza izigqibo, kuquka ixesha lokunxiba okanye lokuphakamisa izithintelo zobunzima bendlela.
UBischof uthi iinzame zokwandisa inethiwekhi yaseMinnesota ifumene inkxaso ebanzi. Abantu abaninzi babona uncedo lokuba nolwazi lwemozulu yendawo ukunceda ukukhokela izigqibo ngezolimo. Olunye kolo khetho lokufama lunempembelelo enkulu.
“Sinenzuzo kumafama kwaye sikwaluncedo kwimithombo yamanzi,” utshilo uBischof. “Ngemali evela kwiNgxowa-mali yaManzi aCocekileyo, ulwazi oluphuma kwezi zikhululo zemozulu luya kunceda ukukhokela izigqibo zezolimo ezingazunceda umlimi kuphela kodwa zicuthe ifuthe lobutyebi bamanzi ngokunceda abo balimi ukuba bawasebenzise ngcono amagalelo ezityalo namanzi.
"Ukwenziwa ngcono kwezigqibo ze-agronomic kukhusela amanzi angaphezulu ngokuthintela ukuhamba ngaphandle kwesiza kwezibulali-zinambuzane ezinokukhukuliseka ziye kumanzi akufutshane angaphezulu, zithintele ilahleko yomgquba kunye neekhemikhali zezityalo ekubalekeni kwamanzi angaphezulu; ukunciphisa ukuvuza kwenitrate, umgquba kunye neekhemikhali zezityalo kumanzi aphantsi komhlaba; kunye nokwandisa ukusetyenziswa kwamanzi okunkcenkceshela."
