Large molecular weight alginates which are covalently modified to store and release nitric oxide, as well as methods of making and use thereof, are disclosed herein. The covalently modified alginates may be tailored to release nitric oxide in a controlled manner and are useful for eradication of both planktonic and biofilm-based bacteria.

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.

Liquid agricultural compositions comprising pasteurized Chlorella cells, as well as methods of preparation and use thereof, are disclosed. The compositions are formulated for application to a plant, seed, seedling, or soil and are effective in enhancing at least one plant characteristic including, but not limited to: seed germination, seedling emergence, seedling size, plant fresh weight, plant dry weight, utilization, leaf production, leaf formation, thatch height, plant maturation, plant yield, plant growth, plant quality, plant health, plant resistance to salt stress, plant resistance to heat stress, plant resistance to heavy-metal stress, plant resistance to drought, maturation time, yield, root length, root mass, color, fruit production, fruit yield, fruit growth, and fruit quality.
