Nitrogen Sensors for Crop Fields

Does anyone know of any technology that will detect and provide levels of nitrogen in the soil? 

Thanks.  Brian

1. If you deal with well irrigated soil you can try and use soil solution extraction ceramic cups to sample the soil solution and check the nitrate and other nitrogen component. The best is to do it in a well equipped lab. There ares some field analysing kits that give mainly qualitative results.

   If the soil is dry the only practical and reliable way is tacking soil sample to the laboratory.

2. Interest Ask.Are there sensors or determinants of the output from the soil of other elements - carbon oxygen, moisture?

    

   Интересный вопрос. Имеются ли датчики или определители выхода из почвы других элементов - кислорода углерода, влаги?

3. Computers on newer tractors analyse the color of the plants and adjust N applications based on need

4. During I was studying M.Sc. in Envi Eng, I use test kit of Merck andvthe result is reasonable because analytical in lab get the result very slow for Total N or NO3 NH3 NO2 measuring and produce the hazadous waste.
