Super Absorbent Polymer
Chemical main element
Particle mesh size
PH value(1g/l water)
Insoluble in water and organical solution;
Swells to a gel upon contact with aqueous fluids .
Maximum Absorption Free swelling conditions
350min in distilled water
110min in soil
Use condition in soil
Applying 0.2%SAP in red soil,the saturated
soil moisture content is 64.94%,
which increased 22.31% ,than control ,
the available soil water
content is 41.35%, which increased
36.47% than control ;
Applying 0.2% SAP in sandy soil, the saturated
soil moisture content is 34.78%,
which increased 32.60% than control, the available
soil water content is 30.90%,
which increased 37.70% than control.
Effectiveness in Soils
It can notably improve soil structure, reduce soil bulk Density
and increase the soil porosity.
In red soil,applying 0.1%,0.2%,0.4%,the soil bulk density
decrease7.33% ,11% ,14.68%;
In sandy soil, applying 0.1%,0.2%,0.4%,the soil bulk density
but two soil porosity increase with the increasing of SAP .
Water available for plants
under 0.3Mpa suction section, it`s the aptest to utilize
Moisture by plant .
non toxic for plants,soil organism/ no chloridion
