In Tulevaisuuden maanviljelijät project we had an experiment in 2021-2022 to investigate the effects of increasing the soil micro-organism population on a compacted, conventionally managed pasture. Experiment was aimed to show the effects of inoculating compacted, conventionally managed pastureland with soil microorganisms by utilizing aerobic thermophilic compost. The compost produced and the soil treatments applied were done according to the Soil Food Web method. This article presents the research approach and the results of the experiment and the theory of soil food web approach.
