Kuidas m\u00f5\u00f5ta mulla makrotoitaineid?<\/strong><\/h2>\n\n\n\n

\u00d5nneks ei pea keegi pinnast lakkuma, et m\u00f5\u00f5ta selles sisalduvaid toitaineid.<\/p>\n\n\n\n

Teadlased nagu Dr. Maria L. Braunger<\/a> ja Dr. Antonio Riul Jr<\/a> t\u00f6\u00f6tavad elektroonilise keele kallal, et seda teha. M\u00f5lemad teadlased t\u00f6\u00f6tavad v\u00e4lja uusi strateegiaid ja seadmeid, et tegeleda toitainete m\u00f5\u00f5tmisega pinnases.<\/p>\n\n\n\n

Kuid kuidas see seade t\u00f6\u00f6tab ja miks on vaja m\u00f5\u00f5ta mulla toitainete sisaldust?<\/p>\n\n\n\n

Nagu Dr. Braunger ja Dr. Riul \u00fctlesid dokumendis nende t\u00f6\u00f6<\/a>: \"Maailma kasvav n\u00f5udlus toidu j\u00e4rele ilma tootmispindade suurendamiseta n\u00f5uab p\u00f5llumajandus- ja loodusressursside paremat kasutamist, mis t\u00e4hendab, et t\u00e4psema p\u00f5llumajanduse paremate vahendite v\u00e4ljat\u00f6\u00f6tamine peaks v\u00e4ltima pestitsiidide ja v\u00e4etiste liigset kasutamist. Selles kontekstis on t\u00e4psusp\u00f5llumajandusega tegelemisel mulla iseloomustamiseks vajalik v\u00e4ga \u00fcksikasjalik teave oluline mullaharimise ja p\u00f5llukultuuride tootlikkuse jaoks.\"<\/p>\n\n\n\n

Mida on vaja teada<\/h2>\n\n\n\n

K\u00f6\u00f6giviljade kasvatamisel on vaja mineraaltoitaineid, et tagada p\u00f5llukultuuri areng.<\/p>\n\n\n\n

Mineraalained on kahte liiki, mikrotoitained ja makrotoitained, kusjuures see jaotus ei ole seotud suurema v\u00f5i v\u00e4iksema vajalikkusega, vaid p\u00f5llukultuuri poolt vajamineva kogusega.<\/p>\n\n\n\n

Vaadake Mind the Graph galerii<\/a> mullaga seotud illustratsioonid. Kl\u00f5psake alloleval pildil!<\/p>\n\n\n\n

\"mullaga<\/a><\/figure>\n\n\n\n

\u00dcks seletus makrotoitainete suurele vajadusele on asjaolu, et neil on struktuuriline roll, nad esinevad DNA (desoks\u00fcribonukleiinhappe) ja RNA (ribonukleiinhappe) v\u00e4ikestes osades, ens\u00fc\u00fcmide aktiveerimisel ja fotos\u00fcnteesis.<\/p>\n\n\n\n

Kuus keemilist elementi on makrotoitainete mineraalid: L\u00e4mmastik (N), fosfor (P), kaalium (K), kaltsium (Ca), magneesium (Mg) ja v\u00e4\u00e4vel (S).<\/p>\n\n\n\n

T\u00e4ppisp\u00f5llumajandus t\u00e4hendab, et mullas on \u00f5ige kogus makro- ja mikrotoitaineid ning autorid r\u00f5hutavad, kui oluline on s\u00e4ilitada terve muld. <\/p>\n\n\n\n

Selline p\u00f5llumajanduslik l\u00e4henemine v\u00f5tab arvesse k\u00f5iki olemasolevaid andmeid, et parandada maapiirkondade tootmise t\u00f5husust, tootlikkust ja j\u00e4tkusuutlikkust. K\u00f6\u00f6giviljadel on erinevad vajadused ja muld peaks andma neile k\u00f5ik vajalikud toitained, et v\u00f5imaldada tervislikku kasvu. Kuid toitainete kogus ei ole mullast inimsilmale n\u00e4htav ja seet\u00f5ttu tuleb seda m\u00f5\u00f5ta. <\/p>\n\n\n\n

T\u00e4nap\u00e4eva tehnoloogia m\u00f5\u00f5dab mulla toitaineid, saates proovid aeglaseks ja kalliks keemiliseks anal\u00fc\u00fcsiks erilaboratooriumi. Autori elektrooniline keel (e-tongue) on n\u00fc\u00fcdisaegne seade, mis lubab l\u00fchidalt kohalikku, kiiret ja odavat anal\u00fc\u00fcsi.<\/p>\n\n\n\n

Aga mis on e-k\u00f5ne ja kuidas see maitseb mulda?<\/strong><\/h2>\n\n\n\n

Inimese maitsemeel h\u00f5lmab maitsemeeli, mis tuvastavad soolaseid, hapu, m\u00f5ru, magusaid ja umami maitseid. Maitsepungade maitseretseptorirakud vastutavad s\u00fcljes lahustunud toiduainetes sisalduvate ioonidega reageerimise eest.<\/p>\n\n\n\n

Rakud saadavad ajule m\u00f5\u00f5tmatut elektrilist teavet maitse kohta. <\/p>\n\n\n\n

E-keel on seade, mis imiteerib inimese vastet ja koosneb \u00fcldjuhul maitsepungi simuleerivatest sensori\u00fcksustest. L\u00fchidalt \u00f6eldes, vedelikku kastetuna suudavad sensori\u00fcksused tunnetada v\u00e4liskeskkonna muutusi oma elektriliste omaduste muutumise kaudu.<\/p>\n\n\n\n

Seade<\/h3>\n\n\n\n

Mullaproovi m\u00f5\u00f5tmiseks tuleb muld lahustada vees ja lasta see l\u00e4bi nelja sensori massiivi.<\/p>\n\n\n\n

Proov toimib kui dielektriline keskkond ja andur kui paralleelkondensaator. Proovis olevad ioonid, mis l\u00e4bivad andurimassiivi, muudavad impedantsi erinevalt vastavalt iga anduri\u00fcksuse moodustavate materjalide elektrilisele iseloomule. <\/p>\n\n\n\n

Elektrilise reaktsiooni erinevus tekitab anal\u00fc\u00fcsitava proovi s\u00f5rmej\u00e4lje. Anduri mahtuvusliku impedantsi andmed saadakse 25 mV amplituudiga siinussignaali sageduse p\u00fchkimisega vahemikus 1 Hz kuni 1 MHz.<\/p>\n\n\n\n

V\u00f5ttes arvesse k\u00f5igi m\u00f5\u00f5tmis\u00fcksuste varieeruvust koos ja rakendades matemaatilist k\u00e4sitlust, on v\u00f5imalik saada proovi m\u00f5\u00f5tmispunkt 2D-tasapinnalisel graafikul. <\/p>\n\n\n\n

J\u00e4rgmine v\u00e4ljakutse<\/h3>\n\n\n\n

Siiani v\u00f5is e-k\u00f5ne vastata kvalitatiivselt ja t\u00e4nap\u00e4eval on v\u00e4ljakutse kvantitatiivne m\u00f5\u00f5tmine, kui palju kaaliumi (n\u00e4iteks) on mullaproovis. <\/p>\n\n\n\n

Alternatiiviks on kasutada standardmulda (mis on n\u00e4iteks kaaliumirikas) ja meetod \u00fctleb, kui kaugel proov sellest standardist on, hinnates kaaliumi kogust mullaproovis. Iga makrotoitaine standardi olemasolu v\u00f5imaldab kontrollida, kas proov on igast makrotoitaine standardist liiga l\u00e4hedal v\u00f5i liiga kaugel (vastavalt vaene v\u00f5i rikas).<\/p>\n\n\n\n

\"Mind<\/a><\/figure>\n\n\n\n

E-keele vastuse olemasolu ja seega teadmine toitainete tasakaalust mullas v\u00f5imaldab p\u00f5llumajandustootjal juhtida mullakorrektsiooni, valides \u00f5iget v\u00e4etist konkreetses piirkonnas, v\u00e4hendades seega pimesi tehtud valikust tulenevat raiskamist.<\/p>\n\n\n\n

T\u00e4ppisp\u00f5llumajanduse eesm\u00e4rk on v\u00e4hendada raiskamist ja parandada tootlikkust ning selle seadmega soovivad dr Braunger ja dr Raul aidata t\u00e4ppisp\u00f5llumajandust odava, lihtsa, kiire ja kohapeal kasutatava seadmega. Loodame, et peagi on e-tongid p\u00f5llumeestele abiks tuleviku p\u00f5llumajanduses.<\/p>\n\n\n\n
