    Phosphorus uptake patterns and yield responses of barley fertilized with meat and bone meal

    In this study we evaluated the effect of P acquisition during the growth period based on its subsequent effect on barley yield using two different P sources, either superphosphate (SP), a soluble P source, or meat and bone meal (MBM), representing a low-solubility P source (Ylivainio et al., 2008)

    N balance as an indicator of N leaching in long-term leaching fields

    In the Finnish conditions, annual N leaching from the experimental plots was not adequately estimated using the respective annual N balances, or supplementing the estimation with annual precipitation, total runoff, or drainage runoff (Salo and Turtola, 2006). Values averaged over the years improved the estimation when management included such environmentally risky managements as bare fallow or off-season application of cow slurry (Salo and Turtola, 2006). Calculated with the linear regression (Salo and Turtola, 2006), N leaching was 20-57 % of the averaged N balance

    Biomassanurmi estää tehokkaasti typen huuhtoutumista

    Saraturvemaassa kasvavasta biomassanurmesta huuhtoutuu liukoista typpeä kymmenessä vuodessa noin 40 prosenttia rehunurmea vähemmän. Samassa ajassa liukoisen fosforin kuormitus vähenee lähes 20 prosenttia. Tämä johtuu vähäisestä lannoitemäärästä ja pitkästä viljelykierrosta.VokKVAMK
