[Objective] For solving the problems of drought and nutrients loss caused by soil erosion

a series of studies on water and fertilizer saving were conducted in order to expound the effects of water pad on fertilizer and water saving and its application prospect.[Methods] Compared to the conventional method of mixing water absorbing polymer (WAP) with soils

WAP was used to make water pad to obtain a better water and fertilizer saving effect.[Results] Under the same watering condition

the application of water pad could reduce water loss by 65%

and reduce nitrogen

phosphorus and potassium nutrients loss by more than 89%. Pot experiment showed that under drought stress condition

the application of water pad could increase corn yield by 155%. Field experiment showed that under natural rainfall condition

the application of water pad could increase corn yield by 26%

and increase sugarcane yield by 10.5%

and the sugar degree increaed. In addition

with the application of water pad

nitrogen

phosphorus and potassium nutrients loss decreased

while nutrients absorption increased.[Conclusion] A serial of experiments indicate that water pad can increase crop yields

quality and nutrient uptake.
