Three sludge types from the same treatment stream (undigested liquid, anaerobically digested liquid and dewatered, anaerobically digested cake) were used in a field based tub study. Amendments (4, 8, and 16 Mg dry solid (ds)ha(-1)) were incorporated into the upper 15 cm of a sandy loam soil prior to sowing with rye-grass (Lolium perenne L.). Nitrogen transformations in the soil were determined ...

Italian ryegrass is one of the most important temperate forage grasses on a global basis. Improvement of both dry matter yield and quality of herbage have been major objectives of pasture grass breeding over the last century. F1 and F2 progeny sets derived from controlled pair-crosses between selected Italian ryegrass genotypes have been evaluated for yield and nutritive quality under field con...

Highly digestible forages are associated with an in vitro low-methane (CH 4 ) rumen fermentation profile and thus the possibility of reducing CH emissions from forage-based systems. We aimed to assess ruminal profile, including production, top stratum Kikuyu grass ( Cenchrus clandestinus - Hochst. ex Chiov harvested at different sward heights (10, 15, 20, 25, 30 cm). Herbage samples (incubating...

Grassland for livestock production is a major form of land use throughout Europe and its intensive management threatens biodiversity and ecosystem functioning in agricultural landscapes. Modest increases to conventional grassland biodiversity could have considerable positive impacts on the provision of ecosystem services, such as pollination, to surrounding habitats.Using a field-scale experime...

ion of the functions/system (including software and hardware) constructed out of these building blocks. 1. IT investments: valuation and performance A trio of papers in this issue enhances our understanding of issues crucial to how firms should think about investing in new technology: how and how much information systems improve performance. An Application of the Learning Curve and the NonConst...

Effective management of dairy farms requires an accurate prediction pasture biomass. Generally, estimation biomass site-specific data, or often perfect world assumptions to model systems when field measurements other sensory inputs are unavailable. However, for small enterprises, regular data inconceivable. In this study, we approach the by predicting sward heights across field. A convolution b...

Grazing management is a key element determining herbage production and grazing efficiency. This study measured herbage accumulation and grazing efficiency in Mombaça grass pastures (Panicum maximum cv. Mombaça) subjected to intermittent defoliation managements. Treatments were combinations of 2 rest periods (grazing at either 95 or 100% canopy light interception — LI) and 2 grazing intensities ...

Establishing forage legumes into endophyte-infected tall fescue (Festuca arundinacae Schreb.) pastures is problematic, especially in well-established stands. A oversowing field experiment determined if this problem was because of poor nodulation. Four renovation techniques, clipped sward (treatment A), herbicided + rye seeding in the previous autumn (treatment B), herbicided in the autumn and s...
