Abstract: A method for securing seeds in an automatic seeding process includes the steps of placing individual seeds in pellets in a tray on a conveyor belt and then securing the seeds on each pellet by placing a gel film over each seed so that the pellets can be transported to a greenhouse. The gel film is provided by contacting a gel precursor with a gelling agent in the presence of the seed.

Abstract: Water is separated from an emulsion of water and oil by passing the emulsion through a bed of superabsorbent polymer granules which break the emulsion and absorb water from the mixture of water and oil. An apparatus for separating water from an emulsion of water and oil has at least one separation cell containing a bed of super absorbent polymer granules.

Abstract: A method for securing seeds in an automatic seeding process is provided wherein: (A) a plurality of individual seeds are each placed in a selected location on a horizontal surface of a growth medium; and (B) a gel film is provided over each said seed to thereby secure each said seed in position on said horizontal surface of said growth medium. said gel film being provided by contacting said gel precursor with said gelling agent substantially in the presence of said seed.
