Cum se m\u0103soar\u0103 macronutrien\u021bii din sol?<\/strong><\/h2>\n\n\n\n

Din fericire, nimeni nu trebuie s\u0103 ling\u0103 solul pentru a m\u0103sura nutrien\u021bii prezen\u021bi \u00een el.<\/p>\n\n\n\n

Oameni de \u0219tiin\u021b\u0103 ca Dr. Maria L. Braunger<\/a> \u0219i Dr. Antonio Riul Jr.<\/a> lucreaz\u0103 la o limb\u0103 electronic\u0103 pentru a face acest lucru. Ambii cercet\u0103tori dezvolt\u0103 noi strategii \u0219i dispozitive pentru a face fa\u021b\u0103 m\u0103sur\u0103rii nutrien\u021bilor din sol.<\/p>\n\n\n\n

Dar cum func\u021bioneaz\u0103 acest dispozitiv \u0219i de ce exist\u0103 o cerere pentru m\u0103surarea nutrien\u021bilor din sol?<\/p>\n\n\n\n

A\u0219a cum au spus Dr. Braunger \u0219i Dr. Riul \u00een munca lor<\/a>: \"Cererea mondial\u0103 \u00een cre\u0219tere de alimente f\u0103r\u0103 a cre\u0219te suprafa\u021ba productiv\u0103 necesit\u0103 o mai bun\u0103 utilizare a resurselor agricole \u0219i naturale, ceea ce implic\u0103 faptul c\u0103 dezvoltarea unor instrumente mai bune pentru agricultura de precizie ar trebui s\u0103 evite utilizarea excesiv\u0103 a pesticidelor \u0219i a \u00eengr\u0103\u0219\u0103mintelor. \u00cen acest context, informa\u021biile foarte detaliate pentru caracterizarea solului sunt importante pentru gestionarea solului \u0219i productivitatea culturilor atunci c\u00e2nd este vorba de agricultura de precizie.\"<\/p>\n\n\n\n

Ce trebuie s\u0103 \u0219ti\u021bi<\/h2>\n\n\n\n

La cultivarea legumelor, nutrien\u021bii minerali sunt necesari pentru a asigura dezvoltarea culturii.<\/p>\n\n\n\n

Exist\u0103 dou\u0103 tipuri de nutrien\u021bi minerali, micronutrien\u021bi \u0219i macronutrien\u021bi, aceast\u0103 \u00eemp\u0103r\u021bire nu este corelat\u0103 cu o mai mare sau mai mic\u0103 esen\u021bialitate, ci cu cantitatea de care are nevoie cultura.<\/p>\n\n\n\n

\"ilustra\u021bii<\/a><\/figure>\n\n\n\n

O explica\u021bie pentru faptul c\u0103 macronutrien\u021bii sunt necesari \u00een cantit\u0103\u021bi mari este faptul c\u0103 ace\u0219tia au un rol structural, sunt prezen\u021bi \u00een p\u0103r\u021bile mici ale ADN (acidul dezoxiribonucleic) \u0219i ARN (acidul ribonucleic), \u00een activarea enzimatic\u0103 \u0219i \u00een fotosintez\u0103.<\/p>\n\n\n\n

\u0218ase elemente chimice sunt considerate minerale macronutriente: Azot (N), Fosfor (P), Potasiu (K), Calciu (Ca), Magneziu (Mg) \u0219i Sulf (S).<\/p>\n\n\n\n

Agricultura de precizie \u00eenseamn\u0103 s\u0103 ai \u00een sol cantit\u0103\u021bile corecte de macronutrien\u021bi \u0219i micronutrien\u021bi, iar autorii subliniaz\u0103 importan\u021ba men\u021binerii unui sol s\u0103n\u0103tos. <\/p>\n\n\n\n

Aceast\u0103 abordare a agriculturii va lua \u00een considerare toate datele disponibile pentru a \u00eembun\u0103t\u0103\u021bi eficien\u021ba, productivitatea \u0219i durabilitatea produc\u021biei rurale. Legumele au nevoi diferite, iar solul ar trebui s\u0103 le ofere toate substan\u021bele nutritive necesare pentru a permite o cre\u0219tere s\u0103n\u0103toas\u0103. Dar cantitatea de nutrien\u021bi nu este vizibil\u0103 pentru ochiul uman pe sol \u0219i, prin urmare, trebuie m\u0103surat\u0103. <\/p>\n\n\n\n

Tehnologia actual\u0103 m\u0103soar\u0103 nutrien\u021bii din sol prin trimiterea de probe la un laborator specializat pentru o analiz\u0103 chimic\u0103 lent\u0103 \u0219i costisitoare. Limba electronic\u0103 a autorului (e-tongue) este un dispozitiv de ultim\u0103 genera\u021bie care promite \u00een scurt timp o analiz\u0103 local\u0103, rapid\u0103 \u0219i ieftin\u0103.<\/p>\n\n\n\n

Dar ce este o limb\u0103 electronic\u0103 \u0219i cum gust\u0103 solul?<\/strong><\/h2>\n\n\n\n

Percep\u021bia gustativ\u0103 uman\u0103 implic\u0103 papilele gustative care detecteaz\u0103 aromele s\u0103rate, acre, amare, dulci \u0219i umami. Celulele receptoare ale gustului din papilele gustative sunt responsabile de reac\u021bia cu ionii prezen\u021bi \u00een produsele alimentare dizolvate \u00een saliv\u0103.<\/p>\n\n\n\n

Celulele trimit la creier informa\u021bii electrice imense despre gust. <\/p>\n\n\n\n

Limba electronic\u0103 este un dispozitiv care imit\u0103 omologul uman \u0219i este compus, \u00een general, dintr-o serie de unit\u0103\u021bi de detec\u021bie care simuleaz\u0103 papilele gustative. Pe scurt, atunci c\u00e2nd sunt scufundate \u00eentr-un lichid, unit\u0103\u021bile de detec\u021bie pot sim\u021bi varia\u021biile din mediul extern prin modific\u0103ri ale caracteristicilor lor electrice.<\/p>\n\n\n\n

Dispozitivul<\/h3>\n\n\n\n

Pentru a m\u0103sura o prob\u0103 de sol, solul trebuie solubilizat \u00een ap\u0103 \u0219i trecut printr-o matrice de patru senzori.<\/p>\n\n\n\n

Proba ac\u021bioneaz\u0103 ca un mediu dielectric, iar senzorul ca un condensator cu pl\u0103ci paralele. Ionii prezen\u021bi \u00een e\u0219antion care trec prin re\u021beaua de senzori modific\u0103 impedan\u021ba \u00een mod diferit, \u00een func\u021bie de natura electric\u0103 a materialelor care formeaz\u0103 fiecare unitate de detec\u021bie. <\/p>\n\n\n\n

Diferen\u021ba de r\u0103spuns electric genereaz\u0103 o amprent\u0103 a probei analizate. Datele de impedan\u021b\u0103 capacitiv\u0103 ale unui senzor sunt ob\u021binute prin intermediul unei baleieri de frecven\u021b\u0103 \u00eentre 1 Hz \u0219i 1 MHz a unui semnal sinusoidal cu o amplitudine de 25 mV.<\/p>\n\n\n\n

Lu\u00e2nd \u00een considerare varia\u021bia tuturor unit\u0103\u021bilor de detec\u021bie \u00eempreun\u0103 \u0219i aplic\u00e2nd un tratament matematic, este posibil s\u0103 se ob\u021bin\u0103 un punct de m\u0103surare pentru un e\u0219antion \u00eentr-o diagram\u0103 plan\u0103 2D. <\/p>\n\n\n\n

Urm\u0103toarea provocare<\/h3>\n\n\n\n

P\u00e2n\u0103 \u00een prezent, limba electronic\u0103 ar putea avea un r\u0103spuns calitativ, iar provocarea actual\u0103 este o m\u0103surare cantitativ\u0103 a cantit\u0103\u021bii de potasiu (de exemplu) prezent\u0103 \u00eentr-o prob\u0103 de sol. <\/p>\n\n\n\n

O alternativ\u0103 este de a avea un sol standard (bogat \u00een potasiu, de exemplu), iar metoda va spune c\u00e2t de departe este e\u0219antionul de acel standard, estim\u00e2nd cantitatea de potasiu din e\u0219antionul de sol. Av\u00e2nd un standard pentru fiecare macronutrient, este posibil s\u0103 se verifice dac\u0103 un e\u0219antion este prea aproape sau prea departe (s\u0103rac sau, respectiv, bogat) de fiecare dintre ele.<\/p>\n\n\n\n

\"cifr\u0103<\/a><\/figure>\n\n\n\n

Av\u00e2nd r\u0103spunsul e-tongue \u0219i cunosc\u00e2nd astfel echilibrul nutrien\u021bilor din sol, agricultorul poate gestiona corec\u021bia solului prin alegerea \u00eengr\u0103\u0219\u0103mintelor potrivite \u00eentr-o anumit\u0103 regiune, reduc\u00e2nd astfel risipa cauzat\u0103 de o alegere oarb\u0103.<\/p>\n\n\n\n

Reducerea risipei \u0219i \u00eembun\u0103t\u0103\u021birea productivit\u0103\u021bii este scopul agriculturii de precizie, iar cu acest dispozitiv, Dr. Braunger \u0219i Dr. Raul doresc s\u0103 ajute agricultura de precizie cu un dispozitiv ieftin, simplu, rapid \u0219i utilizat la fa\u021ba locului. Sper\u0103m s\u0103 avem \u00een cur\u00e2nd e-tongo-uri care s\u0103 ajute fermierii \u00een agricultura viitorului.<\/p>\n\n\n\n
