An experiment was conducted to compare a bunker silo sealing system comprising an oxygen barrier film (OB: 45μm thickness) with protective woven polypropylene with one comprising standard black polyethylene film (S; 125μm thickness) with protective tyres. Analysis of samples taken to 30 cm depth after 365 days of storage showed no differences in pH or lactic acid between the two sealing systems. There were no differences in aerobic bacterial count between silages. Whilst 2.56 log10 CFU moulds g-1 fresh weight were found in samples of silage sealed with S, no moulds were found in samples of silage sealed with OB. Aerobic stability, averaged 249 hours and 184 hours for OB and S, respectively. The OB system probably inhibited the development of the micro-organisms responsible for the initiation of aerobic deterioration to a greater extent than the standard silo sealing system.
This chapter draws on results from previous chapters, in some cases creating new syntheses by combining information across chapters and including findings of previous projects. Its specific objective is to consolidate all these findings in the design of a system to support transaction of information for environmental assessments and decision support at central and local levels, by local managers of land and species as well as by policymakers. It recognises the need not merely to provide a technological tool, but also to consider demand and supply for information in that tool, the ease of use of the tool, motivation to use the tool and cost of maintaining the tool long-term: a tool that is not desirable, practical, and durable will not last. The chapter therefore first addresses who makes the most decisions, finding not only that local managers of land and species have high need of support, but also that their demand is least met by model-based decision support despite their high capacity to generate data. For this reason a system was designed primarily to accommodate needs of knowledge transfer at local level. Consideration of data quality, ownership, and confidentiality was important, together with scale, uncertainty (and resulting liability) of resulting decision support. All these considerations can be addressed by developing trust in operation of such a system, for which a basis in the civic sector (rather than in private business or government) was recommended. A portal was launched to continue informing all interests of the scope for building and opportunities from use of such a system.
There is a debate whether supplementary feeding of game species is necessary, and what type of supplementary food is appropriate for them. In our study a new type of supplemental food for wild game species was evaluated. Fresh tomato pomace mixed with ground maize grains (20% w/w on a fresh basis) was baled. Different additive treatments were made and crude protein and crude fibre content and fermentation profile were evaluated. Consumption of tomato pomace silage by wild ungulates was also measured. Ground maize grains increased the dry matter content and crude protein : crude fibre ratio of tomato pomace. Tomato pomace mixed silage had a limited fermentation capacity with appropriate pH and fermentation acid content. The special baling technology was suitable to form well-shaped bales. In the investigated hunting preserve tomato pomace was the dominant food component in the diet of ungulate species. According to our results, tomato pomace could provide suitable quality supplementary food for large game species.
The case study in 16 km2 around the Municipality of Bózsva surveyed attitudes and mapped an area that had been flooded. Further mapping, to plan a potential cycle route, revealed issues with bureaucracy and a need for training in the use of digital technology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
