A method of introducing treatment agents comprising medicine or nutrients into a tree, involving the boring of holes above ground into the trunk of the tree. Homogeneous plugs of solidified polyethylene glycol (PEG) with such treatment agents mixed therein are molded and inserted into the holes in the tree trunk and sealed with wax. The dissemination time of the treatment agent into the tree trunk is controlled by selection of the PEG's used, with higher molecular weights PEG's taking longer to dissolve and disseminate the treatment agent into the transpirational flow of the tree being treated than the lower molecular weight PEG's. The method leaves no foreign material such as plastic casings or cartridges within the tree trunk after treatment.

Dissolving polymer plug for introducing nutrients and medicinal materials into tree trunks

A soil amendment material and an associated process for the preparation thereof, comprising a water swellable hydrophilic polymer infused with high concentrations of plant nutritive salts. The amendment is prepared by repeated soaking of hydrophilic swellable polymer particles in a solution of nutritive salts in water, followed by heat application to drive off the entrained water, leaving the nutrients entrapped in the polymer particles.

Soil amendment material and process for preparation thereof

A method and composition for the treatment of iron chlorosis in plants using hydroxamic acid-type siderophores. Siderophores of this type are ferric-specific chelators, which are produced by certain microorganisms grown in iron-free environments. The current invention contemplates the use of the siderophore rhodotorulic acid to treat and prevent iron chlorosis. Rhodotorulic acid is produced by the yeast Rhodotorula pilimanae. The siderophore may be applied to the plant by a variety of methods including by soil application, foliar spray or direct injection into the plant.
