Mokslininkai, pvz. Dr. Maria L. Braunger<\/a> ir Dr. Antonio Riul jaunesnysis<\/a> rengia elektronin\u012f lie\u017euv\u012f, kad tai b\u016bt\u0173 galima padaryti. Abu tyr\u0117jai kuria naujas strategijas ir prietaisus, skirtus maistingosioms med\u017eiagoms dirvo\u017eemyje matuoti.<\/p>\n\n\n\n

Ta\u010diau kaip \u0161is prietaisas veikia ir kod\u0117l reikia matuoti dirvo\u017eemio maisting\u0105sias med\u017eiagas?<\/p>\n\n\n\n

Kaip teig\u0117 dr. Braungeris ir dr. Riul j\u0173 darb\u0105.<\/a>: \"Did\u0117janti pasaulin\u0117 maisto paklausa nedidinant gamybini\u0173 plot\u0173 reikalauja geresnio \u017eem\u0117s \u016bkio ir gamtos i\u0161tekli\u0173 naudojimo, o tai rei\u0161kia, kad kuriant geresnes tiksliosios \u017eemdirbyst\u0117s priemones reik\u0117t\u0173 vengti pernelyg didelio pesticid\u0173 ir tr\u0105\u0161\u0173 naudojimo. \u0160iame kontekste tiksliosios \u017eemdirbyst\u0117s srityje labai svarbi labai i\u0161sami dirvo\u017eemio apib\u016bdinimo informacija yra svarbi dirvo\u017eemio valdymui ir pas\u0117li\u0173 produktyvumui.\"<\/p>\n\n\n\n

K\u0105 reikia \u017einoti<\/h2>\n\n\n\n

Auginant dar\u017eoves reikia mineralini\u0173 maistini\u0173 med\u017eiag\u0173, kad b\u016bt\u0173 u\u017etikrintas pas\u0117li\u0173 vystymasis.<\/p>\n\n\n\n

Mineralin\u0117s maistin\u0117s med\u017eiagos yra dviej\u0173 r\u016b\u0161i\u0173 - mikroelementai ir makroelementai; \u0161is skirstymas susij\u0119s ne su didesniu ar ma\u017eesniu reikalingumu, o su augalams reikalingu kiekiu.<\/p>\n\n\n\n

Patikrinkite Mind the Graph galerija<\/a> su dirvo\u017eemiu susijusi\u0173 iliustracij\u0173. Spustel\u0117kite \u017eemiau esant\u012f paveiksl\u0117l\u012f!<\/p>\n\n\n\n

Vienas i\u0161 paai\u0161kinim\u0173, kod\u0117l makroelement\u0173 reikia daug, yra tas, kad jie atlieka strukt\u016brin\u012f vaidmen\u012f, yra ma\u017eose DNR (deoksiribonukleor\u016bg\u0161ties) ir RNR (ribonukleor\u016bg\u0161ties) dalyse, ferment\u0173 aktyvacijoje ir fotosintez\u0117je.<\/p>\n\n\n\n

\u0160e\u0161i cheminiai elementai laikomi makroelementais: Azotas (N), fosforas (P), kalis (K), kalcis (Ca), magnis (Mg) ir siera (S).<\/p>\n\n\n\n

Tikslioji \u017eemdirbyst\u0117 rei\u0161kia, kad dirvo\u017eemyje turi b\u016bti tinkamas makroelement\u0173 ir mikroelement\u0173 kiekis, o autoriai pabr\u0117\u017eia, kaip svarbu palaikyti sveik\u0105 dirvo\u017eem\u012f. <\/p>\n\n\n\n

Dar\u017eov\u0117s turi skirtingus poreikius, tod\u0117l dirvo\u017eemis tur\u0117t\u0173 apr\u016bpinti jas visomis maistin\u0117mis med\u017eiagomis, reikalingomis sveikam augimui. Ta\u010diau dirvo\u017eemyje esantis maistini\u0173 med\u017eiag\u0173 kiekis \u017emogaus akiai n\u0117ra matomas, tod\u0117l j\u012f reikia i\u0161matuoti. <\/p>\n\n\n\n

\u0160iandienin\u0117 technologija dirvo\u017eemio maisting\u0105sias med\u017eiagas nustato siun\u010diant m\u0117ginius \u012f specializuot\u0105 laboratorij\u0105, kurioje atliekama l\u0117ta ir brangi chemin\u0117 analiz\u0117. Autoriaus sukurtas elektroninis lie\u017euvis (e. lie\u017euvis) - tai modernus prietaisas, kuris \u017eada trump\u0105 vietin\u0119, greit\u0105 ir pigi\u0105 analiz\u0119.<\/p>\n\n\n\n

Ta\u010diau kas yra e. lie\u017euvis ir kaip jis ragauja dirvo\u017eem\u012f?<\/strong><\/h2>\n\n\n\n

Elektroninis lie\u017euvis - tai prietaisas, imituojantis \u017emogaus lie\u017euv\u012f, kur\u012f paprastai sudaro daugyb\u0117 skonio receptorius imituojan\u010di\u0173 jutikli\u0173. Trumpai tariant, panardinti \u012f skyst\u012f jutikliai gali pajusti i\u0161orin\u0117s aplinkos poky\u010dius, nes kei\u010diasi j\u0173 elektrin\u0117s charakteristikos.<\/p>\n\n\n\n

Norint i\u0161matuoti dirvo\u017eemio m\u0117gin\u012f, dirvo\u017eem\u012f reikia i\u0161tirpinti vandenyje ir praleisti pro keturi\u0173 jutikli\u0173 matric\u0105.<\/p>\n\n\n\n

M\u0117ginys veikia kaip dielektrin\u0117 terp\u0117, o jutiklis - kaip lygiagre\u010dios plok\u0161t\u0117s kondensatorius. Per jutiklio matric\u0105 einantys m\u0117ginyje esantys jonai skirtingai kei\u010dia var\u017e\u0105, atsi\u017evelgiant \u012f kiekvien\u0105 jutiklio element\u0105 sudaran\u010di\u0173 med\u017eiag\u0173 elektrin\u0119 prigimt\u012f. <\/p>\n\n\n\n

Pagal elektrinio atsako skirtum\u0105 sukuriamas analizuojamo m\u0117ginio pir\u0161t\u0173 atspaudas. Jutiklio talpin\u0117s var\u017eos duomenys gaunami 1 Hz-1 MHz da\u017eniu kei\u010diant 25 mV amplitud\u0117s sinusin\u012f signal\u0105.<\/p>\n\n\n\n

Atsi\u017evelgiant \u012f vis\u0173 jutikli\u0173 variacij\u0105 kartu ir taikant matematin\u012f apdorojim\u0105, galima nustatyti m\u0117ginio matavimo ta\u0161k\u0105 2D plok\u0161tumos br\u0117\u017einyje. <\/p>\n\n\n\n

Kol kas e. lie\u017euvis gali tur\u0117ti kokybin\u012f atsak\u0105, o \u0161iuo metu i\u0161\u0161\u016bkis yra kiekybinis kalio kiekio (pvz., dirvo\u017eemio m\u0117ginyje) matavimas. <\/p>\n\n\n\n

Alternatyva - tur\u0117ti standartin\u012f dirvo\u017eem\u012f (pvz., turting\u0105 kalio), o taikant metod\u0105 bus nustatyta, kiek m\u0117ginys skiriasi nuo to standarto, ir taip bus \u012fvertintas kalio kiekis dirvo\u017eemio m\u0117ginyje. Turint kiekvieno makroelemento standart\u0105, galima patikrinti, ar m\u0117ginys yra per arti arba per toli (atitinkamai skurdus arba turtingas) nuo kiekvieno makroelemento.<\/p>\n\n\n\n
