Kako izmeriti makrohranila v tleh?<\/strong><\/h2>\n\n\n\n

Na sre\u010do nikomur ni treba lizati zemlje, da bi izmeril vsebnost hranilnih snovi v njej.<\/p>\n\n\n\n

Znanstveniki, kot je Dr. Maria L. Braunger<\/a> in . Dr. Antonio Riul ml.<\/a> pripravljajo elektronski jezik, ki bo to omogo\u010dal. Oba raziskovalca razvijata nove strategije in naprave za merjenje hranil v tleh.<\/p>\n\n\n\n

Toda kako ta naprava deluje in zakaj obstaja potreba po merjenju hranilnih snovi v tleh?<\/p>\n\n\n\n

Dr. Braunger in dr. Riul sta v njihovo delo<\/a>: \"Vedno ve\u010dje svetovno povpra\u0161evanje po hrani brez pove\u010danja proizvodnih povr\u0161in zahteva bolj\u0161o rabo kmetijskih in naravnih virov, kar pomeni, da je treba z razvojem bolj\u0161ih orodij za precizno kmetijstvo prepre\u010diti pretirano rabo pesticidov in gnojil. V tem okviru so zelo podrobne informacije za opis tal pomembne za upravljanje tal in produktivnost pridelkov pri preciznem kmetijstvu.\"<\/p>\n\n\n\n

Kaj morate vedeti<\/h2>\n\n\n\n

Pri gojenju zelenjave so potrebna mineralna hranila, ki zagotavljajo razvoj pridelka.<\/p>\n\n\n\n

Poznamo dve vrsti mineralnih hranil, mikrohranila in makrohranila, pri \u010demer ta delitev ni povezana z ve\u010djo ali manj\u0161o nujnostjo, temve\u010d s koli\u010dino, ki jo potrebuje pridelek.<\/p>\n\n\n\n

Oglejte si Galerija Mind the Graph<\/a> za ilustracije, povezane s tlemi. Kliknite na spodnjo sliko!<\/p>\n\n\n\n

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

Ena od razlag, zakaj so makrohranila potrebna v velikih koli\u010dinah, je dejstvo, da imajo strukturno vlogo, da so prisotna v majhnih delih DNK (deoksiribonukleinske kisline) in RNK (ribonukleinske kisline), pri encimski aktivaciji in fotosintezi.<\/p>\n\n\n\n

\u0160est kemi\u010dnih elementov velja za makrohranilne minerale: du\u0161ik (N), fosfor (P), kalij (K), kalcij (Ca), magnezij (Mg) in \u017eveplo (S).<\/p>\n\n\n\n

Natan\u010dno kmetijstvo pomeni, da je treba v tleh zagotoviti prave koli\u010dine makro- in mikrohranil, avtorji pa opozarjajo na pomen ohranjanja zdravih tal. <\/p>\n\n\n\n

Ta pristop k kmetijstvu bo upo\u0161teval vse razpolo\u017eljive podatke za izbolj\u0161anje u\u010dinkovitosti, produktivnosti in trajnosti pode\u017eelske proizvodnje. Vrtnine imajo razli\u010dne potrebe, tla pa jim morajo zagotavljati vsa hranila, potrebna za zdravo rast. Vendar koli\u010dina hranil na tleh ni vidna \u010dlove\u0161kemu o\u010desu, zato jo je treba izmeriti. <\/p>\n\n\n\n

Dana\u0161nja tehnologija meri hranila v tleh tako, da vzorce po\u0161lje v specializiran laboratorij, kjer se opravi po\u010dasna in draga kemi\u010dna analiza. Avtorjev elektronski jezik (e-jezik) je najsodobnej\u0161a naprava, ki v kratkem obljublja lokalno, hitro in poceni analizo.<\/p>\n\n\n\n

Toda kaj je e-jezik in kak\u0161en okus ima zemlja?<\/strong><\/h2>\n\n\n\n

\u010clove\u0161ko zaznavanje okusa vklju\u010duje zaznavanje slanih, kislih, grenkih, sladkih in umami okusov. Okusne receptorske celice v brbon\u010dicah so odgovorne za reakcijo z ioni, ki so prisotni v \u017eivilih, raztopljenih v slini.<\/p>\n\n\n\n

Celice po\u0161ljejo v mo\u017egane ogromno elektri\u010dnih informacij o okusu. <\/p>\n\n\n\n

E-jezik je naprava, ki posnema \u010dlove\u0161ki jezik in je obi\u010dajno sestavljena iz niza senzori\u010dnih enot, ki simulirajo brbon\u010dice. Na kratko, ko so senzorske enote potopljene v teko\u010dino, lahko ob\u010dutijo spremembe v zunanjem okolju s spremembami svojih elektri\u010dnih lastnosti.<\/p>\n\n\n\n

Naprava<\/h3>\n\n\n\n

\u010ce \u017eelite izmeriti vzorec tal, ga je treba raztopiti v vodi in spustiti skozi niz \u0161tirih senzorjev.<\/p>\n\n\n\n

Vzorec deluje kot dielektri\u010dni medij, senzor pa kot vzporedni kondenzator. Ioni, ki so prisotni v vzorcu in prehajajo skozi sklop senzorjev, razli\u010dno spreminjajo impedanco glede na elektri\u010dno naravo materialov, ki sestavljajo vsako senzorsko enoto. <\/p>\n\n\n\n

Razlika v elektri\u010dnem odzivu ustvari prstni odtis analiziranega vzorca. Podatki o kapacitivni impedanci senzorja se pridobijo s frekven\u010dnim razponom med 1 Hz in 1 MHz sinusnega signala z amplitudo 25 mV.<\/p>\n\n\n\n

\u010ce upo\u0161tevamo spremembe vseh zaznavnih enot skupaj in uporabimo matemati\u010dno obdelavo, lahko dobimo merilno to\u010dko za vzorec na 2D ravninskem diagramu. <\/p>\n\n\n\n

Naslednji izziv<\/h3>\n\n\n\n

Zaenkrat se je e-jezik lahko kakovostno odzval, izziv pa je danes kvantitativna meritev, koliko kalija (na primer) je prisotnega v vzorcu zemlje. <\/p>\n\n\n\n

Druga mo\u017enost je, da imamo standardno prst (na primer bogato s kalijem), metoda pa pove, koliko je vzorec oddaljen od tega standarda, in oceni koli\u010dino kalija v vzorcu prsti. \u010ce imamo standard za vsako makrohranilo, lahko preverimo, ali je vzorec preblizu ali preve\u010d oddaljen (reven oziroma bogat) od vsakega makrohranila.<\/p>\n\n\n\n

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

Odziv e-jezika in s tem poznavanje ravnovesja hranil v tleh omogo\u010da kmetu, da upravlja korekcijo tal z izbiro pravega gnojila na dolo\u010denem obmo\u010dju in tako zmanj\u0161a izgube zaradi slepe izbire.<\/p>\n\n\n\n

Cilj preciznega kmetijstva je zmanj\u0161ati koli\u010dino odpadkov in izbolj\u0161ati produktivnost, s to napravo pa \u017eelita Dr. Braunger in Dr. Raul pomagati preciznemu kmetijstvu z napravo, ki je poceni, preprosta, hitra in se uporablja na kraju samem. Upamo, da bomo kmalu imeli e-jezika, ki bosta kmetom pomagala v kmetijstvu prihodnosti.<\/p>\n\n\n\n
