IUnited States ngumlimi omkhulu kunazo zonke kunye nomthengisi wezazi. Izityalo zase-US isivuno sonyaka sembewu entwasahlobo kunye nokuvunwa kwenzeka ngexesha lokuwa. Ngako oko, i-contract yezabelo ze-corn ye-December kwi-Chicago Board of Trade (CBOT) ye-Chicago Mercantile Exchange (i- CME ) yiyona "isivumelwano esitsha". Isityalo esitsha sibhekisela kwisivuno esingekho emhlabathini okanye okwangoku okwandayo.
Ummbiwa ngumthengi ongaqhelekanga; ichaphazela zonke iinkalo zobomi bethu bemihla ngemihla. Ngaphandle kwempahla yayo njengokutya, ingqolowa isisithako esibalulekileyo e-US kumbane olawula amandla zethu izithuthi. I-Ethanol e-US imveliso yengqolowa; Enyanisweni, umntu ngamnye wase-US udla malunga nama-16.5 ebhoksi yonyaka ngamnye ngefuthe. Kuyamangalisa ukuba zininzi iimveliso zemihla esiya nazo ziqule ukutya. Iiplanga, iphepha lodonga, iifestile kwiifestile, upende, iileyile kunye ne-plywood zonke ziquka ingqolowa. Xa kuziwa kwimoto yethu, ingqolowa ayikho kuphela kwiitanki zamatye.
Izihlalo zesikhumba ezidangayo zifuna ummbila kunye namathayi afaka ingqolowa. Kakade, ingqolowa yinxalenye ebalulekileyo yokutya kwansuku zonke. Ii-Chips kunye nokutya okutyiwa ngokutya zidla ixesha elide lifuna i-oil corn okanye i-cornstarch kwimveliso yazo. I-Ketchup, isardard kunye nomshukela oshushuyo zonke ziqule ingqolowa njengesithako kunye neziphuzo ezifana ne-soda zisoloko zifumana ukunambitheka kwazo kwi-syrup isiliva.
Ubhiya kunye newayini ekusebenziseni inkozo kwinkqubo yokuvumba. Iphepha, iino, i-adhesives, kunye ne-glues ziqule ingqolowa. Iibhotile zeplastiki kunye nezikhonkwane zonke ziqule ummbila njengemigca yeebhotile kunye neebhaliweyo ezichonga iziqulatho. I-Cornstarch ibambe iimveliso eziyimfuneko ukuvelisa i-aspirin kunye.
Ingqolowa nayo isetekisi esetyenziswayo ukuvelisa ezinye ukutya.
Kuthatha malunga neepounds ezili-10 zengqolowa ukuvelisa enye ipondo yenkomo ngelixa kuthatha iipilisi ezintathu zengqolowa ukwenza enye ipondo yenkukhu. Umntu ngamnye eUnited States uyadla malunga nama-43.6 engqolowa yenkomo ngonyaka ngamnye - njengokuba ibhasi ilinganisa iipounds ezingama-56 ezilingana nama-2.441.6 iilidi zamanqaku okusetyenziswa komzi ngamnye ngomntu ngamnye ngonyaka. Amanqaku ayaphazamisayo. Ngabantu abangama-32 base-United States abantu abayizigidi ezingama-321, oko kuthetha ukuba abathengi badinga iibhasi eziyi-14 zeebhiliyoni okanye ii-784 billion zeebhondi ngonyaka. Oku kuse-US kuphela. Umveliso wonyaka we-ngqolowa ophuma kwi-US kunye nehlabathi jikelele. Njengemveliso yezolimo, ingqolowa ixhomekeka kakhulu kwiimeko ezikhulayo. Ngako oko, ixesha elikhulayo elinomtsalane omncinci, okanye isomiso, liya kunciphisa isivuno semveliso yesityalo njengoko kuya kwenza unyaka xa kuninzi umswakama, okanye izikhukhula. Ukulungiselela isivuno sembewu esilungileyo, izimo zezulu ezifanelekileyo ziyimfuneko. Ngonyaka ka-2012, isivuno sembewu sasihlwayelwa yimbalela ebhubhisayo e-US Ngokuphendula kwiimeko ezomileyo; amanani eembombo ahlanganiselwe kwixesha eliphakamileyo lika-8.4375 ngebhasi. Kwiminyaka emibini elandelwayo, imozulu efanelekileyo kunye neemeko ezikhulayo zikhokelela ekuveliseni izityalo ezikhulayo, ezazisa amanani aphantsi.
Ukususela ngoJuni 30, ngo-2015, intengo ye-endlela ye-corn kwi-CBOT yayithengisa i-$ 4.315 kwizinga lebhasi-49% ngaphantsi kwexabiso leminyaka emithathu ngaphambi. Ngo-2016, intengo yengqolowa iwele phantsi kwe-$ 3.50 ngebhasi.
Ixabiso lentengo yintengo yonke imvelo. Imijikelezo ye-Bull yamashishini kaninzi ivula indlela yokuthwala imijikelezo yemarike. Zininzi izinto ezibandakanya ukubonelelwa kunye nezidingo ezisisiseko ezichaphazela le mijikelezo. Xa kuziwa kwimveliso yezolimo, imozulu ngamnye ngonyaka mhlawumbi iyona nto ibaluleke kakhulu. Ingqolowa yintengiso ebalulekileyo kwi-US kunye nabathengi behlabathi ngokusetyenziswa ezininzi. Ixabiso langoku lenkomo lihluma esinye isivuno esihle ngexesha le-2015. Oko kukunyuka kokholo ekubeni akukho mntu kodwa uMama Wendalo uyazi oko ikusasa elibambelele kwisityalo.
Ngoko ke, ngamaxabiso kwinqanaba eliphantsi kuninzi kwiminyaka emininzi, ukuphazamiseka ngokumalunga nexabiso kunqamle kwaye umgca, njengokuba sibonile ngo-2012, unokuqhuma. Ixabiso langoku lemboni libonelela abatyala-mali ithuba lokungenakuncipheko ukuba bafumane inzuzo xa le mveliso yezityalo zonyaka ingezantsi. Ukongezelela, ummbila uthembisa ukuba yinto ekhangayo yokutshala imali kwiminyaka ezayo ukuba amaxabiso ahlala kwinqanaba elixinezelekileyo langoku. Inani labantu libonisa ukukhula kwabantu behlabathi kunye nobutyebi obukhulayo kwimarike ekhulayo, njengeTshayina ne-Indiya, ukufunwa kweefama kunokwandiswa kwiminyaka ezayo. Iimveliso zengqolowa kwi-exchange exchange and there are ETF kunye ne-ETN iimveliso ezibonisa intsebenzo yentengo kule marike ebalulekileyo yengqolowa.
Uphuhliso olutshanje kwiMbewu
Ngo-2015, abalimi baseU.S. bakhiqiza esinye isivuno sembewu ye-corn and 2016, kubonakala ngathi ukuveliswa kwendawo yengqolowa kuya kuphinda kudlule ukufunwa kwehlabathi jikelele. Ixabiso lentaka liphakama ngokukhawuleza ngexesha lokutshala emva kwexesha le-2016 lifikelela kumaqondo angaphezulu kwamaRandi angama-4.50 ngebhasi, kodwa inkqubela phambili yezolimo yenza ukuba ixabiso liwele phantsi kwe-$ 3.50 njengemozulu kunye kunye neemarike kulindeleke omnye umnyaka wokuveliswa kwemfuyo.
Enye into eyayilinganisa intengo yengqolowa ngo-2016 yayiyi-drop in the price of ethanol. EUnited States, inxalenye ebalulekileyo yesityalo sembewu yonyaka iyadingeka ekuveliseni i-ethanol. Ukuncipha kwixabiso le-ethanol ukusuka kwi-$ 1.70 ukuya ngaphantsi kwe-$ 1.40 nganye nge-gallon phakathi kwentwasahlobo kunye nephakathi kwehlobo le-2016 kwabangela ukuba intengo yengqolowa ilahle. Ingqolowa yintsimi yonyaka kwaye nangona kwakukho izityalo ezinobuncwane ukususela ngo-2013 ukuya ku-2015 kwaye kuya kwenzeka ukuba kubekho esinye isivuno esikhulu ngo-2016, akukho ziqinisekiso ukuba oku kuya kuqhubeka kwikamva.
