sap for corn

Researchers around the world (especially Iran, China, Europe and the United States) have widely used SAP to improve water efficiency and increase crop yields. Various studies strongly suggest that the use of super-absorbent polymers for soil conditioning can be used as an innovative aspect in the agricultural field, and SAP can be regarded as a miniature reservoir. Research evidence shows that better water management can be achieved through the use of polymers, and substantial water savings can be achieved without affecting crop yields.

The reduction of water is a major problem in corn production, because the special growth period of corn is more sensitive to water shortage, and drought restricts the normal growth of corn, leading to huge economic losses. We conducted field trials to study the effects of hydrogel on different aerobic rice seeding techniques. The percentage of soil moisture before each irrigation was recorded. Compared with the soil without hydrogel, the application of hydrogel improved the soil moisture content in all three seeding techniques. More soil moisture meets the crop’s moisture needs and increases the number of germinating seeds. Due to the higher emergence rate, the yield of corn in the soil improved by the hydrogel was also increased.
