In order to determine the differences between organic and conventional agrophytocenoses in regards to their input for maintaining and increasing below-ground biodiversity, a field study was conducted in the demonstration fields of the Agroecological Center of the Agricultural University in Plovdiv, Bulgaria. The biodiversity of soil geobionts was established for a two-year period (2013–2014) by monitoring the changes in environmental parameters, considering conducted agricultural activities. The obtained data were compared with parallel monitoring of a conventional apple orchard. The ecological parameters were higher in all the investigated taxa in the organic orchard.
