Hvordan m\u00e5ler man makron\u00e6ringsstoffer i jorda?<\/strong><\/h2>\n\n\n\n

Heldigvis er det ingen som trenger \u00e5 slikke p\u00e5 jorda for \u00e5 m\u00e5le n\u00e6ringsinnholdet i den.<\/p>\n\n\n\n

Forskere som Dr. Maria L. Braunger<\/a> og Dr. Antonio Riul Jr.<\/a> jobber med en elektronisk tunge for \u00e5 gj\u00f8re det. Begge forskerne utvikler nye strategier og utstyr for \u00e5 h\u00e5ndtere m\u00e5ling av n\u00e6ringsstoffer i jordsmonnet.<\/p>\n\n\n\n

Men hvordan fungerer dette apparatet, og hvorfor er det behov for \u00e5 m\u00e5le n\u00e6ringsstoffer i jordsmonnet?<\/p>\n\n\n\n

Som Dr. Braunger og Dr. Riul sa i sin artikkel sitt arbeid<\/a>: \u201cThe growing world demand for food without increasing the productive area requires better use of agricultural and natural resources, which implies that the development of better tools for precision agriculture should avoid excessive use of pesticides and fertilizers. Within this context, high-detailed information for soil characterization is important for soil management and crop productivity when dealing with precision agriculture.\u201d<\/p>\n\n\n\n

Det du trenger \u00e5 vite<\/h2>\n\n\n\n

Ved dyrking av gr\u00f8nnsaker er det n\u00f8dvendig med mineralske n\u00e6ringsstoffer for \u00e5 sikre avlingens utvikling.<\/p>\n\n\n\n

There are two types of mineral nutrients, micronutrients, and macronutrients, this division does not correlate with greater or lesser essentiality, but with the amount needed by the crop.<\/p>\n\n\n\n

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

En forklaring p\u00e5 det h\u00f8ye behovet for makron\u00e6ringsstoffer er at de har en strukturell rolle, inng\u00e5r i de sm\u00e5 delene av DNA (deoksyribonukleinsyre) og RNA (ribonukleinsyre), i enzymatisk aktivering og i fotosyntesen.<\/p>\n\n\n\n

Six chemical elements are considered Macronutrient minerals: Nitrogen (N), Phosphorus (P), Potassium (K), Calcium (Ca), Magnesium (Mg), and Sulfur (S).<\/p>\n\n\n\n

Precision agriculture stands for having the right quantities of Macronutrients and Micronutrients in the soil, and the authors state the importance of maintaining healthy soil. <\/p>\n\n\n\n

Denne tiln\u00e6rmingen til landbruk vil ta hensyn til alle tilgjengelige data for \u00e5 forbedre effektiviteten, produktiviteten og b\u00e6rekraften i landbruket. Gr\u00f8nnsakene har ulike behov, og jorda b\u00f8r gi dem alle n\u00e6ringsstoffene de trenger for \u00e5 vokse sunt. Men mengden n\u00e6ringsstoffer i jorden er ikke synlig for det menneskelige \u00f8yet, og m\u00e5 derfor m\u00e5les. <\/p>\n\n\n\n

Today\u2019s technology measures the soil nutrients by sending samples to a specialized laboratory for slow and expensive chemical analysis. The author’s electronic tongue (e-tongue) is a state-of-the-art device that promises shortly a local, fast, and cheap analysis.<\/p>\n\n\n\n

Men hva er en e-tunge og hvordan smaker den p\u00e5 jorden?<\/strong><\/h2>\n\n\n\n

The human taste perception involves taste buds detecting salty, sour, bitter, sweet, and umami flavors. Taste receptor cells in the taste buds are responsible to react with ions present in foodstuff dissolved in saliva.<\/p>\n\n\n\n

Cellene sender en enorm mengde elektrisk informasjon om smaken til hjernen. <\/p>\n\n\n\n

E-tungen er en enhet som etterligner den menneskelige tungen, og den best\u00e5r vanligvis av en rekke sensorenheter som simulerer smaksl\u00f8kene. Kort fortalt kan sensorene, n\u00e5r de er nedsenket i en v\u00e6ske, f\u00f8le variasjoner i det ytre milj\u00f8et gjennom endringer i de elektriske egenskapene.<\/p>\n\n\n\n

Enheten<\/h3>\n\n\n\n

For \u00e5 m\u00e5le en jordpr\u00f8ve m\u00e5 jorda oppl\u00f8ses i vann og f\u00f8res gjennom en matrise med fire sensorer.<\/p>\n\n\n\n

The sample acts as a dielectric medium and the sensor as a parallel plate capacitor. Ions present in the sample passing through the sensor array change the impedance differently, according to the electrical nature of the materials forming each sensing unit. <\/p>\n\n\n\n

The difference in the electrical response generates a fingerprint of the analyzed sample. The capacitive impedance data of a sensor is acquired by a frequency sweep between 1 Hz and 1 MHz of a sinusoidal signal with 25 mV of amplitude.<\/p>\n\n\n\n

Ved \u00e5 ta hensyn til variasjonen i alle sensorenhetene samlet og anvende en matematisk behandling, er det mulig \u00e5 f\u00e5 et m\u00e5lepunkt for en pr\u00f8ve i et 2D-plott. <\/p>\n\n\n\n

Den neste utfordringen<\/h3>\n\n\n\n

S\u00e5 langt har e-tungen kanskje gitt et kvalitativt svar, og utfordringen i dag er en kvantitativ m\u00e5ling av hvor mye kalium (for eksempel) som finnes i en jordpr\u00f8ve. <\/p>\n\n\n\n

Et alternativ er \u00e5 ha en standardjord (f.eks. rik p\u00e5 kalium), og metoden sier hvor langt pr\u00f8ven ligger fra denne standarden, og estimerer kaliummengden i jordpr\u00f8ven. \u00c5 ha en standard for hvert makron\u00e6ringsstoff gj\u00f8r det mulig \u00e5 sjekke om en pr\u00f8ve ligger for n\u00e6r eller for langt (henholdsvis fattig eller rik) fra hver enkelt standard.<\/p>\n\n\n\n

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

Ved \u00e5 ha e-tongue-responsen og dermed kjenne balansen mellom n\u00e6ringsstoffene i jorden, kan bonden styre jordkorreksjonen ved \u00e5 velge riktig gj\u00f8dsel i en bestemt region, og dermed redusere sl\u00f8singen ved et blindt valg.<\/p>\n\n\n\n

M\u00e5let med presisjonslandbruk er \u00e5 redusere sl\u00f8sing og \u00f8ke produktiviteten, og med denne enheten \u00f8nsker Dr. Braunger og Dr. Raul \u00e5 hjelpe presisjonslandbruket med en enhet som er billig, enkel, rask og kan brukes p\u00e5 stedet. Vi h\u00e5per snart \u00e5 ha e-tunger som kan hjelpe b\u00f8nder i fremtidens landbruk.<\/p>\n\n\n\n
