Soft-sensing of farmland water potential for precision irrigation
Shengli Lu · Journal of Tianjin University of Technology and Education · 2007
In accordance with the theory of Soil-Plant-Atmosphere Continuum(SPAC)t,he motion of moisture in the continuum is decided chiefly by the water potential differenceF.or the implementation of precision irrigation(PI)i,t is most important to measure precisly farmland water potential.A new method estimating farmland water potential based on information collection and procession of tiny environment for farmland crops is introduced.
