Kwifama enkulu yaseCentral Valley yaseCalifornia, utshintsho lwezolimo oluqhutywa bubuchwephesha lwenzeka ngokuzolileyo. Ifama enkulu yasekuhlaleni, iGolden Harvest Farms, isandula ukwazisa ubuchwepheshe be-RS485 sokuhlola umhlaba ukuze ijonge idatha ebalulekileyo efana nokufuma komhlaba, ubushushu kunye netyuwa ngexesha langempela, ngaloo ndlela kufezekiswa ukunkcenkceshela ngokuchanekileyo kunye nokugcinwa kwamanzi ngokufanelekileyo.
ICentral Valley yaseCalifornia yenye yezona ndawo zibalulekileyo zemveliso yezolimo eMelika, kodwa imbalela eqhubekayo kunye nokunqongophala kwamanzi kwiminyaka yakutshanje kuzise imingeni emikhulu kwezolimo zasekuhlaleni. IGolden Harvest Farm ikhulisa iintlobo ngeentlobo zezityalo ezinexabiso eliphezulu, kuquka ii-almond, iidiliya kunye neetumato. Ukuphendula imeko yokunqongophala kwamanzi, abalimi bagqibe ekubeni basebenzise iteknoloji ye-RS485 yokubona umhlaba ukuze baphucule ulawulo lokunkcenkceshela kunye nokunciphisa inkunkuma yamanzi.
I-RS485 somhlaba sisiva-sensor esichanekileyo kakhulu esisekelwe kwiprotocol yonxibelelwano ye-RS485 enokuqokelela idatha yomhlaba ngexesha langempela kwaye iyithumele kwinkqubo yolawulo oluphakathi ngenethiwekhi eneentambo. Abalimi banokujonga iimeko zomhlaba bekude ngeefowuni eziphathwayo okanye iikhompyutha, kwaye balungise izicwangciso zokunkcenkceshela ngokusekelwe kwidatha ukuqinisekisa ukuba izityalo zikhula phantsi kweemeko ezifanelekileyo.
UMichael Johnson, umphathi wemisebenzi yeGolden Harvest Farm, uthe: “Ii-RS485 solar sensors zitshintshe ngokupheleleyo indlela esinkcenkceshela ngayo. Ngaphambili, besinokugweba kuphela xa kufuneka sinkcenkceshele ngokusekelwe kumava, kodwa ngoku sinokwazi ukuba umhlaba ngamnye udinga amanzi angakanani na. Oku akugcini nje ngokusindisa imithombo yamanzi emininzi, kodwa kukwaphucula nesivuno sezityalo kunye nomgangatho.”
Ngokwedatha yefama, emva kokusebenzisa izinzwa zomhlaba ze-RS485, ukusetyenziswa kwamanzi okunkcenkceshela kuncitshiswe ngama-30%, isivuno sesivuno sinyuke nge-15%, kwaye ityuwa yomhlaba ilawulwa ngokufanelekileyo, oku kuthintela ukuwohloka komhlaba okubangelwa kukunkcenkceshela kakhulu.
Iingcali zezolimo kwiYunivesithi yaseCalifornia, eDavis ziyakuqonda oku. ULisa Brown, uprofesa kwiSikolo seSayensi yezoLimo nezeNdalo kule yunivesithi, uthe: “Izinzwa zomhlaba ze-RS485 zisisixhobo esibalulekileyo kwezolimo oluchanekileyo. Zinokunceda abalimi ukuba basebenzise amanzi ngokufanelekileyo kwiindawo ezomileyo ngelixa bephucula ukuzinza kwemveliso yezolimo. Oku kubaluleke kakhulu kwezolimo eCalifornia nakwihlabathi liphela.”
Amava aphumeleleyo eGolden Harvest Farm akhuthazwa ngokukhawuleza eCalifornia nakwamanye amazwe ezolimo. Abalimi abaninzi baqala ukuqaphela nokwamkela iteknoloji ye-RS485 yokubona umhlaba ukuze bajongane nemingeni enzima yemithombo yamanzi.
“Isixhobo sokuvavanya umhlaba i-RS485 asincedi nje kuphela ukonga iindleko, kodwa sikwasinceda ukuba sikhusele okusingqongileyo ngcono,” wongezelela uJohnson. “Sikholelwa ukuba obu buchwephesha buza kuba ngundoqo kuphuhliso lwezolimo kwixesha elizayo.”
Malunga ne-RS485 somhlaba sensor:
I-RS485 somhlaba sensor sisixhobo esichanekileyo esisekelwe kwiprotocol yonxibelelwano ye-RS485 enokujonga idatha ebalulekileyo efana nokufuma komhlaba, ubushushu kunye netyuwa ngexesha langempela.
I-RS485 somhlaba idlulisela idatha kwinkqubo yolawulo ephakathi ngenethiwekhi eneentambo, inceda abasebenzisi ukuba bafezekise ukunkcenkceshela ngokuchanekileyo nokonga amanzi ngokufanelekileyo.
Isixhobo sokuvavanya umhlaba i-RS485 sifanelekile kwiimeko ezahlukeneyo ezifana nokulima emasimini, ukutyala izityalo eziluhlaza, ulawulo lwegadi yeziqhamo, kwaye sisebenza kakuhle kakhulu kwiindawo ezomileyo.
Malunga nezolimo zaseMelika:
I-United States yeyona mveliso inkulu yezolimo emhlabeni jikelele kwaye ithumela kwamanye amazwe, kwaye ezolimo ziintsika ezibalulekileyo kwezoqoqosho.
ICentral Valley yaseCalifornia yeyona ndawo ibalulekileyo yemveliso yezolimo eMelika, edume ngokulima izityalo ezinexabiso eliphezulu ezifana nee-almond, iidiliya kunye neetumato.
Ulimo lwaseMelika lugxile ekuveliseni izinto ezintsha kwezesayensi nezobuchwepheshe kwaye lusebenzisa ubuchwepheshe bezolimo obuchanekileyo ukuphucula ukusebenza kakuhle kwemveliso kunye nokusetyenziswa kwezixhobo.
