Ben-Gurion College of the Negev (BGU) researchers have developed a brand new nitrate sensor that can present real-time and steady measurement in soil to raised detect water air pollution and measure circumstances for larger agricultural productiveness.
Pure nitrate ranges in groundwater are usually very low. Nevertheless, extra software of fertilizers in agriculture usually ends in leaching of nitrate from the soil to water sources. Elevated ranges of nitrate in water is among the principal causes for disqualification of ingesting water, inflicting a worldwide environmental downside.
The brand new optical nitrate sensor relies on absorption spectroscopy. It permits steady, real-time measurement of nitrate and may detect nitrate concentrations within the vary of tens to a whole bunch of components per million (ppm), which is the vary related to rising crops. Its potential to constantly monitor soil nitrate ranges produces a extremely detailed portrayal of the quickly altering concentrations of nitrate within the soil answer. The brand new sensor can be extremely proof against harsh chemical and bodily soil circumstances.
The invention was developed by Prof. Ofer Dahan of the BGU Zuckerberg Institute for Water Analysis, Prof. Shlomi Arnon of the Division of Electrical and Laptop Engineering, and Elad Yeshno, Ph.D. pupil on the Zuckerberg Institute.
“Current methods for measuring soil nitrate are cumbersome, labor-intensive and do not provide real-time indication on the actual concentration of nutrients in the soil,” says Prof. Dahan.
“Our invention, which enables real-time monitoring of soil nitrate levels, can supply farmers with valuable data on the amount of nutrient availability for crops,” Prof. Arnon says. “It also optimizes fertilizer application, thus preventing over-fertilization, economizes irrigation and reduces water resources pollution.”
In line with Shirley Sheffer Hoffman, senior vice chairman of enterprise growth for water, vitality and agriculture at BGN Applied sciences, BGU’s technology-transfer firm, “This is another example of the cutting-edge multidisciplinary research preformed at the BGU Jacob Blaustein Institutes for Desert Research, in collaboration with BGU’s engineering faculty. This promising project received funding from the Israel Innovation Authority, and now BGN Technologies is seeking an industry partner for its further development and commercialization.”
