| By inserting cover crops into organic cropping systems, the number and biomass of weeds decreased. Winter cover crops clearly have a suppressive effect on weeds by providing competition for light, water and space. |

| Keskkonnasõbralik umbrohutõrje maheviljeluses koosneb viljavaheldusest, äestamisest, vaheltharimisest, multšimisest, liblikõieliste kasvatamisest külvikorras ja vahekultuuride (sh talviste kattekultuuride) kasvatamist (Thorup-Kristensen jt., 2003). Käesoleva uurimisega seotud varasemad tulemused näitasid, et talvistest vahekultuuridest rukis osutus umbrohtudele kõige kahjulikumaks, pärssides umbrohuseemnete idanevust. Mõnevõrra vähem toimis raihein, mida oli märgata järgnevates kultuurides - herne ja odra umbrohutaimede tiheduses (Barberi jt., 2014). Lisaks kasvutihedusele vähendasid talvised vahekultuurid ka umbrohtude biomassi (Madsen jt., 2015). Väiksem umbrohtude arvukus ja biomass mõjutavad ka mulla umbrohuseemnete varu. Käesoleva uurimistöö... |

| The effects of different winter cover crops and their combination with composted cattle manure on weeds and crop yields were investigated within a five-field crop rotation (barley undersown with red clover, red clover, winter wheat, pea, potato) in three organic cropping systems. The control system (Org 0) followed the rotation. In organic systems Org I and Org II the winter cover crops were used as follows: ryegrass (Lolium perenne L. in 2011/2012) and a mixture of winter oilseed-rape (Brassica napus ssp. oleifera var. biennis) and winter rye (Secale cereale L.) in 2012/2013 before pea; winter oilseed rape before potato and winter rye before barley. In Org II system composted cattle manure was also applied. In comparison with the control system, 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. |

| In 2008 an experiment was set up on the field in Eerika experimental station (Estonian University of Life Sciences) as a 5-field crop rotation: red clover, winter wheat, pea, potato and barley undersown with red clover. The objective of the study was to measure the content of weed seeds in the soil and to evaluate the diversity of the species at the end of the period of converting to organic production. In conventional farming systems without fertilizer (Conv I) and conventional farming with mineral fertilizer (Conv II) herbicides were used for weed control. All the crops in Conv II system received P 25 kg ha-1 and K 95 kg ha-1, but the application rates of mineral nitrogen fertilizer differed. In organic systems (Org I – organic farming based on winter... |

| 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. |
