SIA Pindstrup Latvia engages in the study "Wood fibers to improve the properties of peat substrates and reduce the ecological footprint":


Project No. 5.1.1.2.i.0/122/A/CFLA/007 (P20)


Project implementation period: 01.05.2024 – 30.04.2026


Title of the study: "Wood fibers to improve the properties of peat substrates and reduce the ecological footprint"


The study is being implemented with: SIA "Meža nozares kompetences centrs" within the framework of the project.


Objective: To develop recommendations and scientific justifications for the production and application of peat substrate with wood fibres and liming material with additives promoting the growth and resilience of trees in forest nurseries and for the recultivation of degraded areas.


Results achieved in the 1st period (01.05.2024-31.10.2024)

  • A review of wood fiber and wood ash as substitutes for peat and mineral fertilizers and substrate recipes has been prepared.
  • Prepared experimental batch of substrate recipes.


September 2025


Results achieved in the 2nd period (01.11.2024-30.04.2025)


  • Trials have been established in four types of substrates for growing pine/spruce container seedlings and broadleaved cuttings
  • Monitoring of tree growth and survival as well as substrate properties
  • Studies on the efficiency of substrates and substrates with wood ash additives for growing bare-root seedlings
  • Field trials established in the MPS tree nursery experimental area
  • Trials established with the produced seedlings in a reclamation site – gravel pit reclamation in the MPS-managed scientific research forests.


Results achieved in the 3 period (01.05.2025-30.10.2025)

  • Second-season trials have been established in four types of substrates for growing pine/spruce container seedlings and broadleaved cuttings
  • Monitoring of tree growth and survival as well as substrate properties
  • Measurements carried out in the field trial area and a results overview prepared
  • Assessment of survival results
  • An experimental batch of wood fiber “wool” prepared
  • The previously prepared wood fiber “wool” mixed with peat and additives.
