The present disclosure provides a method of increasing aggregation in a soil comprising the step of administering to the soil an amount of a microalgae material to increase aggregation in the soil compared to a substantially identical untreated soil, wherein the microalgae material comprises Chlorella cells and/or Schizochytrium cells. Also disclosed is a method of enhancing the active carbon score of a soil, comprising administering an amount of a microalgae material to the soil to increase the active carbon score of the soil compared to a substantially identical untreated soil, wherein the microalgae material comprises Chlorella cells and/or Schizochytrium cells.

A composition derived or derivable from seaweed is provided. The composition comprises one or more plant hormones; and/or one or more acidic polysaccharides. Also provided is a method for producing a composition, including the step of extracting one or more agents from seaweed. A method of stimulating plant growth by applying a composition derived or derivable from seaweed is also provided.

Antimicrobial compositions comprising gum rosin, pine oil, and salt water mitigate or eliminate detrimental plant microorganisms, and mitigate or reverse plant diseases such as Gram-negative bacterial diseases. The compositions are effective against Gram-negative bacterial diseases (including citrus greening disease or HLB caused by Candidatus Liberibacter, and diseases caused by Xylella fastidiosa), fungal diseases such as those caused by Candida auris, and viral diseases such as those caused by Citrus tristeza virus. The antimicrobial compositions may be used as a root treatment, foliar treatment, or both. The compositions can be diluted into a concentrated mixture and sprayed on the leaves of a diseased plant, or a plant that is prone to disease. The compositions can be used as a root drench or in an irrigation system to treat a diseased plant. The compositions may optionally include surfactants (especially in foliar applications) and growth stimulants (especially in root drench or irrigation applications).
