| Vihmaussidel on oluline roll mullaviljakuse kujunemisel. Nende elutegevuse tagajärjel paraneb orgaanilise aine mineralisatsioon ja lagunemine. Vihmausse peetakse keskkonna hindamise oluliseks vahendiks tänu pidevale kontaktile mullaga, mulla vee ja selles lahustunud sooladega (Ivask, 1996). Vihmaussikoosluste ja struktuuri põhjal saab teha järeldusi põllumajandusliku tegevuse mõjust muldadele. Liikide arv, biomass ja koosluse ökoloogiline struktuur on põllumajanduslikes muldades üks olulisemaid parameetreid, määramaks mulla saastatust ja olukorda (Paoletti, 1999). Vihmausside aktiivsus ja biomass sõltub oluliselt majandamisviisist ning seeläbi mullaharimisest, orgaaniliste või mineraalsete väetiste lisamisest ning mulda viidava orgaanilise aine kogusest.... |

| 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... |
