Description: Water shortage has become a major limiting factor for agricultural production in the North China Plain. Inadequate irrigation practices are causing excessive evaporation and deep percolation losses. Apart from low water efficiency, this leads to leaching of nutrients and increasing pollution of ground water and down-stream aquifers. Therefore, objective of the subproject is to design an innovative mobile micro-irrigation system with site-specific water and fertilizer application based on plant growth modeling and real time soil moisture and plant status measurement. Water-, energy- and fertilizer efficiency of the irrigation system will be evaluated. Finally, the system will be adapted to the socio-economic conditions of the farmers in the North China Plain.
