Primary production is controlled by time-varying soil moisture. Stochastic rainfall inputs. Soil physical properties control storage and “overflow”. Moisture-dependent ET loss. Co-Principal Investigators: Ava Arabshahi, Anika Thomas, Claire O’Connor. Teacher Facilitator: Danalynn Coulon, Open Window School. School: Open Window School. Community: Bellevue, WA. Science Addressed by Experiment. W. ith Fruit Peels. Dry weather conditions and lack regular rainfall encourages water conservative technology of Superabsorbent polymers (SAPs). SAPs have great water absorption capacity relative to its own weight which improves soil moisture and hence reduces water stress on the plant during prolonged drought stress condition and during irrigation intervals. .
