The supplement includes a quantity of specific microbes and an organic acid, such as humic acid, fulvic acid, and ulvic acid. Trace minerals also can be added. A humectant also can be incorporated with the microbes, organic acid, and trace minerals to provide a matrix to provide an improved moisture and nutrient environment and a greatly increased surface area and cation exchange ability for optimizing microbe growth. Chelated micronutrients may also be added to the supplement or added later to the foliage to improve the effects of the supplement still further. Methods of improving plant productivity and quality by treating the plant with the microbes, organic acids and a naturally balanced formulation of chelated minerals are disclosed.Type: GrantFiled: September 27, 1983Date of Patent: August 28, 1990Assignee: Hugh M.

Patent number: 4950601Abstract: A composite structure having a thickness substantially less than its width such as a sheet is prepared which includes a substantially water-insoluble particulate or fibrous support having a surface energy of at least about 30 dynes per cm to which nitrogen-fixing filamentous blue-green algae heterocyst cells are attached. the support does not have a deleterious effect on the attached algae and is preferably cellulosic or a polyoletin such a polypropylene. The structure may contain a first and second layer and have a plurality of raised, three-dimensional shapes over at least a portion of at least one surface. Preparing the composite structure includes contacting the support with blue-green algae to permit the algae to attach to the support by means of heterocyst cells. The attach cells in a nitrogen deficient environment, fix nitrogen at a rate substantially greater than unattached cells, and have agricultural applications.Type: GrantFiled: March 17, 1987Date of Patent: August 21, 1990Assignee: Kimberly-Clark CorporationInventors: J.

Patent number: 4935353Abstract: The invention relates to a strain of Bacillus thuringiensis, GC 91, a sample of which has been deposited under the accession number NCTC 11821, or a derivative or mutant thereof having entomocidal activity against lepidopterous pests. The invention also relates to a process for producing a strain of Bacillus thuringiensis having improved entomocidal properties by combining into a single strain by plasmid transfer the different entomocidal properties of two respective starting strains. The new strains thus produced are useful in entomocidal compositions.Type: GrantFiled: October 4, 1985Date of Patent: June 19, 1990Assignee: Agricultural Genetics Company, LimitedInventors: Denis H.
