Abstract
A superabsorbent polymer (“SAP”) root dip composition and methods of delivering a SAP to a plant are disclosed. A root structure of a plant may be dipped into a SAP hydrogel. The plant may then be planted, stored or transported for subsequent planting.
Claims18
A method of delivering a superabsorbent polymer to a plant, comprising:
- obtaining a superabsorbent polymer hydrogel, wherein the superabsorbent polymer is starch-g-poly (2-propenamide-co-2-propenoic acid) potassium salt starch graft copolymer;
- obtaining a plant having a root structure;
- dipping at least a portion of the root structure of the plant into the superabsorbent polymer hydrogel;
- and
- removing the root structure from the superabsorbent polymer hydrogel.
2 more elements
A method of delivering a superabsorbent polymer to a plant or plant cutting, comprising:
- dipping a portion of the plant or plant cutting into a starch-graft superabsorbent polymer hydrogel, wherein the superabsorbent polymer is starch-g-poly (2-propenamide-co-2-propenoic acid) potassium salt starch graft copolymer;
- removing the plant or plant cutting from the superabsorbent polymer hydrogel;
- and
- planting the plant or plant cutting into soil after removal from the superabsorbent polymer hydrogel.
1 more element
A root dip composition, comprising:
- starch-g-poly (2-propenamide-co-2-propenoic acid) potassium salt starch graft copolymer;
- and
- an effective amount of water mixed with the starch-g-poly (2-propenamide-co-2-propenoic acid) potassium salt starch graft copolymer to form a hydrogel having a viscosity sufficient to coat a plant root dipped therein. pg,23
