متن يادداشت

Invited papers --; Value of animal manures: changes in perception --; Effects of herbage composition and supplement feeding on the excretion of nitrogen in dung and urine by grazing dairy cows --; Manure as a source of nitrogen and phosphorus in soils --; Utilization of nitrogen from injected and surface-spread cattle slurry applied to grassland --; The influence of different processing methods for slurry upon its fertiliser value on grassland --; Utilisation of phosphorus and potassium from animal manures on grassland and forage crops --; Distribution of excreted nitrogen by grazing cattle and its effects on sward quality, herbage production and utilization --; Negative effects of animal manure on grassland due to surface spreading and injection --; Cattle slurry and farmyard manure as fertilizers for forage maize --; Utilization of nitrogen from slurry applied to fodder crops. Research report from the Nordic countries, Denmark, Finland and Sweden --; Extent, effects and tackling of a regional manure surplus: a case-study for a Dutch region --; Nitrogen losses from animal manures: from grazed pastures and from applied slurry --; Phosphorus and heavy metals: accumulation and consequences --; The use of additives in livestock slurries to improve their flow properties, conserve nitrogen and reduce odours --; Economic aspects of the use of animal manures --; The future of animal manures as fertilizer or waste --; Short communications --; Utilization of stored, aerated or anaerobically digested dairy cattle and pig slurries on sown grassland --; Utilization of nitrogen from slurry applied to permanent grassland --; The effectiveness of high doses of cattle slurry as pasture fertilizer in a submontane region --; Yield of hay from grassland treated with mineral fertilizers and slurry --; Yields from swards of varying botanical composition fertilized with cattle slurry --; Mid-season application of organic manures --; a waste of resources? --; Long term effects of slurry on grassland --; The utilization of slurry on light land --; Effects of organic fertilizer application on hay meadow quality in the French Northern Alps --; The effect of regular application of cattle slurry on grassland during the growing season on grass yield and daily milk production --; Trials on slurry application techniques for grassland --; Injector design for minimum grass sward damage --; Investigations of the fertilizer value of sheep excrements left on pasture --; The characterization of cattle slurry and the response of a range of crop plants to slurry application --; Scorching of Lolium perenne caused by cattle slurry --; The effect of cattle slurry on clover in grass/clover swards --; Factors controlling vegetation dynamics in hay meadows under high levels of organic fertilizer in the French Northern Alps --; Effect of cattle dung on the spread of couch grass (Elymus repens L.) in intensive grassland --; Comparative responses to applied fertilizer phosphorus on manured and unmanured soils --; Effect of animal manure on phosphorus and potassium content of herbage --; Utilization of potassium excreted by grazing cattle --; The effect of cattle slurry on the mineral content of pastures and blood serum in dairy cows --; Ammonia volatilization from urine patches in grassland --; Limitations for slurry application to peat grassland --; Effect of treated pig slurry on herbage and groundwater quality --; Nitrate in soil water at different depths during the growing season on permanent pasture (comparison of mineral fertilizer and liquid manure) --; The effect of a nitrification inhibitor on the utilization of nitrogen by grass from injected and surface-applied pig slurry --; The influence of ground superphosphate on the pH value and the ammonia release from slurry --; Separation of pig slurry by sedimentation.
