Ngophuhliso olukhawulezileyo lwetekhnoloji yezolimo echanekileyo, abalimi abaninzi eMelika baqalise ukusebenzisa izinzwa zomhlaba ezisebenza ngeendlela ezininzi ukuphucula imveliso yezolimo. Kutshanje, isixhobo esibizwa ngokuba yi-“7-in-1 soil sensor” siqalise ingcinga kwimarike yezolimo yase-US kwaye siye saba sisixhobo “sobuchwepheshe obumnyama” abalimi abazama ukusithenga. Esi sinzwa sinokujonga ngaxeshanye izalathisi ezisixhenxe ezibalulekileyo zomhlaba, kubandakanya ukufuma, ubushushu, i-pH, ukuqhuba kombane, umxholo we-nitrogen, umxholo we-phosphorus kunye nomxholo we-potassium, nto leyo enika abalimi idatha epheleleyo yempilo yomhlaba.
Umenzi wale sensor uthe esi sixhobo sisebenzisa itekhnoloji ye-Intanethi yezinto (IoT) ephucukileyo ukudlulisa idatha kwifowuni okanye kwikhompyutha yomsebenzisi ngexesha langempela. Abalimi banokujonga imeko yomhlaba ngokusebenzisa isicelo esihambisanayo kwaye balungise ukuchumisa, ukunkcenkceshela kunye nezicwangciso zokutyala ngokusekelwe kwidatha. Umzekelo, xa isensor ibona ukuba umxholo we-nitrogen emhlabeni awonelanga, inkqubo iya kukhumbuza umsebenzisi ngokuzenzekelayo ukuba afake isichumiso se-nitrogen, ngaloo ndlela kuthintelwe ingxaki yokuchumisa kakhulu okanye izondlo ezinganelanga.
ISebe lezoLimo laseMelika (i-USDA) lixhasa ukukhuthazwa kobu buchwepheshe. Isithethi sathi: “Isixhobo sokuvavanya umhlaba esiyi-7-in-1 sisixhobo esibalulekileyo kwezolimo oluchanekileyo. Asinakunceda abalimi kuphela ukwandisa isivuno, kodwa sikwanceda nokunciphisa inkunkuma yezixhobo kunye nokunciphisa impembelelo yokusingqongileyo.” Kwiminyaka yakutshanje, iSebe lezoLimo laseMelika belikhuthaza uphuhliso kwiteknoloji yezolimo ukunciphisa ukusetyenziswa kwezichumisi namanzi ngelixa liphucula isivuno sezityalo kunye nomgangatho.
UJohn Smith, umlimi wase-Iowa, ngomnye wabasebenzisi bokuqala bale sensor. Uthe: “Ngaphambili, besinokugweba kuphela iimeko zomhlaba ngokusekelwe kumava. Ngoku ngale datha, izigqibo zokutyala ziye zaba zezesayensi ngakumbi. Kunyaka ophelileyo, isivuno sam sombona sinyuke nge-15%, kwaye ukusetyenziswa kwezichumisi kwehle nge-20%.
Ukongeza ekuphuculeni ukusebenza kakuhle kwemveliso, i-7-in-1 soil sensor ikwasetyenziswa kakhulu kuphando. Amaqela ophando lwezolimo kwiiyunivesithi ezininzi eMelika asebenzisa ezi zixhobo ukwenza uphando ngempilo yomhlaba ukuphuhlisa iindlela zolimo ezizinzileyo. Umzekelo, abaphandi kwiYunivesithi yaseCalifornia, eDavis bahlalutya idatha ye-sensor ukuze bahlole indlela yokuphucula ukusetyenziswa kwamanzi kwiindawo ezithwaxwe yimbalela.
Nangona ixabiso lale sensor liphezulu, iingenelo zayo zexesha elide zitsala abalimi abaninzi ngakumbi. Ngokwezibalo, ukuthengiswa kwe sensor kuMbindi-ntshona we-United States kunyuke phantse ngama-40% kunyaka ophelileyo. Abavelisi bakwaceba ukuqalisa iinkonzo zokuqeshisa ukuze banciphise umda weefama ezincinci.
Abahlalutyi bakholelwa ukuba ngokusasazwa kobuchwepheshe bezolimo obuchanekileyo, izixhobo ezikrelekrele ezifana ne-7-in-1 soil sensor ziya kuba ngumgangatho wezolimo zexesha elizayo. Oku akuyi kunceda nje kuphela ekusombululeni imingeni yokhuseleko lokutya kwihlabathi liphela, kodwa kuya kukhuthaza ezolimo ukuba ziphuhle ngendlela enobuhlobo nokusingqongileyo nezinzileyo.
