We are doing a lot of research to gather the necessary materials and to find information that supports our Deep Root Irrigation Precipitation System. The posts in this section show what we have done so far.
Information on evapotranspiration from Wikipedia: “Potential evapotranspiration supplements the measurement of rainfall in providing a scientific measurement-based definition of a desert. The water budget of an area can be calculated using the formula P − PE ± S, wherein P is precipitation, PE is potential evapotranspiration rates and S is amount of surface storage...
