| Tänapäeval toimub pidev maakasutuse intensiivistamine, mis omakorda mõjutab mullaorganismide elutegevust. Vihmaussid on maakasutuse ja mullaviljakuse jälgimiseks head indikaatorid. Nende arvukus on suur, nad on kergesti identifiseeritavad ja erinevatest põllumajandustöödest otseselt mõjutatavad. Vihmaussidel on mullas mitmeid ülesandeid. Nad osalevad orgaanilise aine lagunemisel ja mulla mineraliseerumise protsessis, suurendavad selle poorsust, õhutavad ning parandavad veehoiuvõimet ja toitainete olemasolu mullas (Edward ja Bohlen, 1996) suurendades sellega taimekasvu (Brown jt., 2004). Liikudes läbi mulla jätavad vihmaussid endast maha koproliite (Edwards, 2004), mis parandavad lämmastiku, fosfori, kaaliumi, kaltsiumi ja magneesiumi kättesaadavust mullast... |

| Earthworms are the easiest detectable species to evaluate soil conditions on arable land. The aim of current study was to investigate conventional and organic farming practices, including different fertilization schemes effect on earthworms’ abundance, biomass and species diversity. Data were collected in autumn of 2012 from a 5-year crop rotation experiment (pea, potato, barley undersown with red clover, red clover and winter wheat), established near Tartu, at Eerika on sandy loam Albic Stagnic Luvisol in 2008. This rotation was managed under 5 farming systems, two conventional: Conventional I (not fertilized but with addition of chemical pesticides) and Conventional II (mineral fertilized plots with a final fertilization rate of N150P25K95 and with the... |

| In a field experiment based on a five-year crop rotation (pea, potato, barley undersown with red clover, red clover and winter wheat), several soil parameters, porosity, number and biomass of earthworms, total nitrogen, organic carbon, percentage of water stable aggregates and enzymatic activity, were studied during 2013 and 2014, the first and second year, respectively, since the first rotation concluded. This rotation was managed under three organic farming systems: Organic 0 (control), Organic I (with winter cover crops lately incorporated into the soil as green manure) and Organic II (with the same cover crops plus a yearly amendment of 40 t ha−1 of cattle manure). Crop rotation had a yearly positive effect on the soil bulk density, and enhanced the... |

| An introduction of winter cover crops (wcc) into the crop rotation had a positive impact on soil quality in organic cropping systems. Wcc alone and in combination with composted manure enriched soil with organic matter, activated soil life (increased number of earthworms and higher soil microbial activity - FDA), increased soil pH value, and supported nutrient cycling and soil formation. |
