The sensor of the content and quality of organic matter to the soil

摘要

"Sensor of content and quality of organic matter to the soil.The present invention relates to a sensor of organic matter which uses the technique of photoluminescence for measuring the content and assess the quality of organic matter of soils.The technique consists in turning the soil with blue light to stimulate its fluorescence.The fluorescence obtained in this way brings information about the more portions humificadas (or aromatic condensed) of soil organic matter.The relationship between the fluorescence intensity and the degree of humificau00e7u00e3o is positive, that is, the more humificada to soil organic matter is the most intense fluorescence.This system has the advantage of performing direct measures in the soil without the need for laboratory assistance,With complex chemical methods of extraction of organic matter and the fractionation of humic substances.The information provided is related to the content of soil organic matter and its quality with respect to its state of humificau00e7u00e3o.These data are extremely useful to direct the farmer for the better management of soil and crops, and to assist the precision agriculture.Another interesting application is to evaluate the stability of organic matter in the soil in order to assess management systems as sequ00b3estradores of carbon from the atmosphere into the soil.Allowing agricultural systems are coupled with the mitigation of greenhouse gases.
