Measurement Model and Simulation of Soil Nitrate Nitrogen Based on Ion Selective Electrode

Abstract:

The existing conventional detection methods ofnitrate nitrogenmostly consume time, cost a lot of moneyand need professionals. This limits the application of soil testing and fertilization technology at the grass-roots level. Therefore, a kind of fast, low-cost and simple operated method of soil nitrate nitrogen is in urgent need. The research of measurement models based on electrochemical principles of soil nitrate nitrogen is carried out in this paper to the issue ofquick access to the information of soil nitrate nitrogen. The linear regression equation is used to establish the mathematical model of electrodes and the binary quadratic regression model is used to study the temperature correction mathematical model of electrodes and finally matlab is used for datasimulation.
