Update welzijnsprestaties biologische veehouderij Organic Eprints
Ruis, Marko; Pinxterhuis, Ina; Vrolijk, Maarten.
Dit rapport geeft een actuele weergave van de werkelijke welzijnsprestaties van de biologische veehouderijsectoren, en welke ontwikkelingen er gaande zijn. Aan de hand van verbeteragenda's wordt aangegeven waar en hoe nog welzijnswinst te behalen is. De biologische veehouderij wil laten zien dat ze staat voor een maatschappelijk verantwoorde en duurzame productie, met aandacht voor milieu, klimaat, natuur en landschap, voedselkwaliteit, inkomen en dierenwelzijn. Dierenwelzijn als één van de thema’s van duurzaamheid staat centraal in deze rapportage. De bestaande kennis over dit onderwerp is geïnventariseerd voor de melkvee-, varkens-, pluimvee-, schapen- en geitensectoren. De welzijnsprestaties zijn gebaseerd op dierkenmerken en zijn ingedeeld in...

Optimal length of the grass-clover period in crop rotations: results of a 9-year field experiment under organic conditions Organic Eprints
Boer, H. de; Eekeren, N. van; Pinxterhuis, Ina; Stienezen, M.W.J..
A nine year crop rotation experiment was carried out in the Netherlands from 2002 through 2010 to (1) determine the optimal length of the grass-clover (mixture) and maize period in crop rotations and (2) to determine which crops should receive slurry application with priority in case the availability of cattle slurry is limited. The results show that dry matter yield decreased for all treatments over the experimental period, due to a decrease in plant-available N (from N fixation by the clover, applied slurry and mineralization of soil N). The relative yield increase (increase relative to the negative trend) due to slurry application was largest when all crops received slurry application, and the effects of slurry application increased over time.

Integrating maize and triticale in grass/clover based dairy systems: examining yields and autumn soil nitrate levels Organic Eprints
Pinxterhuis, Ina; Boer, H. de; Eekeren, N. van; Stienezen, M.W.J..
To establish N-efficient crop rotations with perennial ryegrass/white clover, maize and triticale, a 9-year field experiment was executed on an organic experimental farm in the Netherlands. Crop rotations with different levels of slurry (dairy effluent from the free-stall barn, average dry matter content of 7%) application were tested for dry matter (DM) yield, N yield, soil mineral N in autumn, soil organic matter and soil organic N. Maize cropping and slurry application both increased annual DM yield. However, the second year of grass/ clover following maize, maize itself and slurry applications each resulted in higher soil mineral N in autumn, increasing the risk of nitrate leaching losses. A rotation of 4 years of grass/clover, 2 years of maize and 1...
