Maintaining or enhancing the stock of soil organic carbon (SOC) is a key factor in sustaining the soil resources of the world. The objective of this research was to study the effect of different farming systems (conventional farming with mineral fertilizers and crop specific fertilization vs. organic farming with organic fertilizers (catch crops and composted manure)) under the same 5-crop rotation (red clover, winter wheat, pea, potato, barley undersown with red clover) system on the SOC stock and the stability of SOC. The second aim was to quantify plant C inputs to the soil and to identify the relationship between C sequestration rate and C input. Data presented in this paper concerned the first rotation during 2008–2012. The main factors were farming... |

A five years research run at the experimental station of the Estonian University of Life Sciences in Eerika, Tartu, Estonia since 2008 on Albic Stagnic Luvisol soil, compared the evolution of different elements (Corg, N, P, K) in soil with time, on the basis of conventional and organic farming. For this aim, 80 plots under the same crop rotation (pea, potato, barley, red clover and winter wheat) were divided as follows: 40 cultivated under conventional farming system with different concentrations of mineral fertilizers (20 without addition of chemical fertilizers: N0P0K0; and 20 with a final concentration equals to N125P25K95) and the remaining 40 plots cultivated under organic farming conditions with winter oil-rape after pea, winter rye after potato and... |

Üheks olulisemaks Eesti muldade funktsionaalsust kahjustavaks teguriks on muldade tihenemine, mille põhjustajateks on nii raske põllumajandustehnika kui ka valed viljelusvõtted ning ühekülgsest mineraalväetistega väetamisest tingitud mulla struktuursuse nõrgenemine. Tihenemise tulemusena väheneb mulla poorsus, vee ja õhu liikumine mullas (Bakken jt., 1987) ning taimed ei suuda nõrgenenud juuresüsteemi tõttu omastada vajalikke toitaineid. Selle tulemusena väheneb saak ning tekib oht toitainete leostumiseks keskkonda. Mulla kvaliteedi säilitamiseks ja parandamiseks on tavaviljelusele alternatiiviks maheviljelus läbi viljavahelduse, orgaaniliste väetiste kasutamise ning keskkonnasõbraliku taimekaitse. Töö eesmärgiks oli uurida, kuidas mõjutab kasutatav... |

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... |

Regarding a soil compaction survey carried out at the end of 2008 by the Estonian University of Life Sciences in collaboration with the Agricultural Research Centre, soil compaction was define as one of the currently bigger problems in Estonian soils (Reintam et al., 2010). Soil compaction reduces porosity, permeability and therefore water flow through the soil is blocked, increasing the soil erosion and creating anoxic conditions in the bulk which causes denitrification, and therefore the uptake of nutrients is reduced (Bakken et al., 1987). In conclusion soil compaction affects directly to the plant root development and crop yield. |

Organic farming systems should be characterized by excellent soil fertility management to keep plant nutrient cycles short and as closed as possible. Therefore, it is extremely important to establish growing systems that have rotations with appropriate crops and intercrops to ensure fertile and biologically active soils, to enhance biodiversity and to provide high quality crop yields. Locally available organic fertilizers include green manures and animal manure. The influence of green manures as intercrops and these combined with composted cattle manure on soil properties, biodiversity indicators and crop yields was studied in a crop rotation experiment in three organic systems at the Estonian University of Life Sciences. |
