" The density of each soil particle determines the size of these pores, and soil pore size plays a decisive role in the amount of water a certain soil can hold onto.
Sometimes referred to as hydrogels or polymer crystals, these small granules absorb and store water - up to 400 times its original density. When tilled into the soil, water crystals will absorb and retain excess water for extended periods.
