ABSTRACT:
A method of improving the crop yield of transplanted crops and of extending the useful life of freshly cut plants utilizing an aqueous gel including a highly absorbent, crosslinked, mixed salt of homopolymerized or copolymerized acrylic acid. The aqueous gels utilized in the present invention not only show improved crop yield and extended plant life in the absence of plant nutrients, but also exhibit sufficient gel strength and rigidity to support the plants in the absence of inert solid aggregates.
