Soil moisture content measurement
This patented device and method can provide real time data of the moisture content of soil, vegetation and snow covered surfaces over large areas. Compared to devices currently on the market (electromagnetic sensors, remote sensing, ambient neutron sensors) it is more reliable, efficient and cost effective.
There are limits to current systems for the measurement of soil moisture content: they are not optimized for continuous use in agriculture or for monitoring over larger scales. This patented invention measures the flux of ambient neutrons deriving from cosmic rays: there is in fact a correlation between the flow of neutrons and the average moisture content in soil, vegetation and snow covered surfaces. This patented method and device can gather simultaneous data from a few hectares of surface and up to 60cm in depth. The neutron probe used is much less expensive than those currently on the market. The real time data acquisition will be especially useful in agriculture, to program precision irrigation, and for climatological studies concerning snow covered surfaces and hydrogeological characteristics of any terrain.
