Hydrogel is a white coloured dry granule which can absorb water several times it's mass and become a transparent hydrated gel. When hydrated gel is incorporated into dry soil it slowly releases absorbed water into the soil and gets rehydrated during rain or addition of water through its property of water absorption and release cycles in soil. This property of Hydrogel can be specifically adopted to supply water to plants for a short but critical period during planting and establishment in dry soil. JK Paper Mills targeted to plant about 8000 ha. per year which is high to achieve during rainy season. Hence a preliminary trial of planting Eucalyptus in dry months of January and March 2011 using Hydrogel was taken up. The root system start growing new roots within a week of planting, penetrate into gel and surrounding soil, and get established. During odd rains received during dry period before rainy season the gel rehydrated and the plants grew at a rate of 1 cm a day. The trial needs to be extended after 2011 rainy season.
