Method for utilizing fine-particle peat

A method for improving the firmness and/or stability of planting substrates on the basis of fine-particle peat,

• wherein the method comprises the following steps:
• (i) a substrate mixture comprising peat is admixed with at least one binder composition comprising at least one binder, wherein the binder composition is formed on the basis of a dispersion or solution, with the dispersion medium or solvent being water, and wherein the binder composition comprises at least one dispersion-based adhesive based on an organic adhesive polymer, wherein the adhesive polymer is selected from the group consisting of polyurethanes (PUs), polylactides (PLAs), acrylates, chloroprene, vinyl acetate-ethylene copolymers (VAEs), polyvinyl alcohols (PVOHs), and polyvinyl acetates (PVAcs), and wherein the binder composition has a solids content in the range of from 0.2 to 25 wt %, based on the binder composition, and a Brookfield viscosity at 20° C. in the range of from 20 to 1,500 mPas;
• and
• (ii) the binder is subsequently allowed to set.
