| A five-year experiment results, have shown that fertilizer amendments are needed for preserving the nutrient balance in the soil. A combination of cattle and green manure, crop rotation and other organic farming practices, with chemical fertilizer amendments could suppose a sustainable solution for maintaining a correct nutrient balance in the soil in long term, better than both farming systems, conventional and organic, by separate. |

| 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... |

| 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.... |

| Since 2008, a 5-year crop rotation experiment (winter wheat, pea, potato, barley undersown with red clover, and red clover) has been run in Tartu, Estonia, to evaluate the changes in soil chemical parameters under four fertilizer managements: (1) unfertilized conventional plots (conventional I), (2) conventional plots with addition of mineral fertilizers (conventional II), (3) organic plots with cover crops during the winter period (organic I), and (4) organic plots with the same cover crops plus a yearly amendment of 40 t ha–1 of cattle manure (organic II). After the first rotation, results showed significant differences (P < 0.05) in soil acidity dependent on the system with mean values ranging between 5.67 (conventional II) and 6.10 (organic II).

| The aim of the current study was to investigate based on a five-year crop rotation experiment (field pea, potato, barley under-sown with red clover, red clover, and winter wheat) situated in Tartu, Estonia, the impact of cover crops (oilseed-rape, rye and perennial ryegrass), alone or with cattle manure (40 t ha-1), in organic farming and mineral fertilizers (up to N150P25K95) effect in conventional farming in soil chemical (pHKCl, SOC, Ntot, available P, K, Mg and Ca) and physical properties (bulk density, porosity, water permeability and penetration resistance) since 2008 till 2014. In addition in 2013–2014 the effect of cover crop on soil aggregate stability, earthworm population and microbial activity (FDA) was also tested in organic farming. After the... |

| Igasuguse põllumajandustootmise, sealhulgas mahetootmise võtmeküsimuseks on kestliku mullaviljakuse tagamine. Mahetootmine põhineb kohaliku taastuva ressursi tasakaalustatud kasutusel ning mullaviljakuse tagamiseks on väga tähtis hoolikalt läbimõeldud ja kohalikesse tingimustesse hästi sobiv külvikord. Külvikorra põhikultuuride vahel on mulla orgaanika ja taimetoitainete varu täiendamiseks otstarbekas kasutada vahekultuure, mis külvatakse peale põhikultuuri koristamist. Vältimaks sügis-talvist taimetoitainete väljaleostumist tasub vahekultuurideks kasutada talvituvaid kultuure nn. talviseid vahekultuure, mis siis enne külvikorrakultuuri külvi mulda viiakse. Seega ei kasvatata vahekultuure mitte otsest müügikasu vaid esmalt ikka mullaparandamist silmas... |

| The influence of green manures as winter cover crops and these combined with composted cattle manure on soil properties, biodiversity indicators and crop yield was studied in a crop rotation experiment in three organic systems at the Estonian University of Life Sciences. The use of green manures as winter cover crops and their combination with cattle manure brought tendencies to improve the soil quality: increased content of organic carbon, pH, soil water permeability, soil water holding capacity, soil microbial activity and abundance of earthworms and ground dwelling arthropods. Depending on the year, yield level of all main crops was increased due to improved soil properties caused by green manures. |
