Abstract
A method is described for improving water retention in soil, which involves mixing a super absorbing resin (SAR) composite with the soil. The SAR composite comprises a natural pozzolan and at least one polymer or copolymer. The SAR composite may be in the form of granules having an average longest dimension of 0.2-10 mm, though the SAR composite may be pelletized or formed in other sizes. The SAR composite may release water at a faster rate in a soil when exposed to drought conditions.
Claims18
A method of improving water retention in a soil, the method comprising:
- mixing a super absorbing resin (SAR) composite with the soil,
- wherein the SAR composite comprises:
- a fibrous base material,
- a natural pozzolan, and
- at least one polymer or copolymer selected from the group consisting of chitosan-alginic acid, chitosan, poly 2-acrylamido-2-methylpropane-sulfonic acid (polyAMPS), polyacrylamide, polyacrylic acid, and sodium alginate,
- wherein a mixture of the natural pozzolan and the at least one polymer is present on the fibrous base material;
- wherein the SAR composite is present at a weight percentage of 0.1-5.0 wt % relative to a weight of the soil.
A method of improving water retention in a soil, the method comprising:
- mixing a super absorbing resin (SAR) composite with the soil,
- wherein the SAR composite comprises:
- a fibrous base material,
- a natural pozzolan, and
- at least one polymer or copolymer selected from the group consisting of chitosan-alginic acid, chitosan, poly 2-acrylamido-2-methylpropane-sulfonic acid (polyAMPS), polyacrylamide, polyacrylic acid, and sodium alginate,
- wherein a mixture of the natural pozzolan and the at least one polymer is present on the fibrous base material;
- wherein the SAR composite further comprises water at a weight percentage of 20-80 wt % relative to a total weight of the SAR composite dry weight and water.
A method of improving water retention in a soil, the method comprising:
- mixing a super absorbing resin (SAR) composite with the soil,
- wherein the SAR composite comprises:
- a fibrous base material,
- a natural pozzolan, and
- at least one polymer or copolymer selected from the group consisting of chitosan-alginic acid, chitosan, poly 2-acrylamido-2-methylpropane-sulfonic acid (polyAMPS), polyacrylamide, polyacrylic acid, and sodium alginate,
- wherein a mixture of the natural pozzolan and the at least one polymer is present on the fibrous base material;
- wherein the at least one polymer or copolymer is cross-linked and has a cross-link density of 100-5,000 mol/cm3.
