Abstract: Cultivation of a microorganism in a nutrient medium including disrupted sea kelp or a sea kelp extract produces a bioactivating fermentation product which promotes growth and yields when applied to plants. A composition containing such bioactivating fermentation product and an acidification extraction product of humic acid is readily absorbed by plant foliage when sprayed on plants.
Abstract: A novel microbial plant growth promoting composition comprising a mixture of a bacteria and algae, and a method of promoting plant growth therewith are disclosed.
