Synthetic hydrophilic polymers (hydrogels) are a particular class of gels, obtained by chemical stabilization of hydrophilic polymers in a tridimensional network (Francesco et al. 2015). Hydrogels are unique class of polymeric materials which imbibe enormous amounts of water when left in a water reservoir for long times (Mahdavinia et al. 2009). Hydrogels have been widely proposed for horticultural purposes over the last 40 years with the basic idea to use the swelling and water release properties to ameliorate water availability for plants. Several possible agricultural applications of hydrogels have been defined (Francesco et al. 2015). Hydrogels have been successfully used as soil improvers to increase the water-holding capacity and/or nutrient retention of sandy soils, with a possible reduction of irrigation frequency, compaction tendency and water run-off. Increased storage pores and reduce power hydraulics saturated by reducing the pore drainage (Narjary et al. 2012).
