<p>This invention relates to a plant food, to a mycelial fertiliser and to a method of producing this fertiliser in all of which an essential constituent is purified pyrolignous acid. The plant food includes 97-80 parts by weight of purified pyrolignous acid and 3-20 parts by weight of saccharide containing glucose. The mycelial fertiliser consists predominantly of thermoactinomyces as mycelium which is obtained by incubation and fermentation on a porous carrier at a pH of 7.5-9.5, in addition to purified pyrolignous acid.</p> |
