A Hybrid Lateral Flow Sand Filter Wastewater Treatment System: An Evaluation On The Treatment And Disposal Capabilities Of A Modified Sand Filter, Harry Mccaskill Iv

<strong> Theses and Dissertations </strong>

Decentralized wastewater treatment exists primarily in suburban and rural areas where centralized treatment is not an option. Traditional on-site treatment systems usually include the use of a septic tank and a drain field. This orthodox method works well when implemented into environments that are accommodating for the infiltration of effluents, and thus allowing for soil treatment. Unfortunately, there are some circumstances that prevent traditional systems from working such as impermeable soil conditions. The Wastewater Treatment System analyzed in this thesis was created to overcome such inhospitable environments. More specifically, this system is catered towards the rural residences of The Alabama …

Portuguese Society Of Pastures And Forages, J. Potes, E. V. Lourenço, T. Carita

IGC Proceedings (1997-2023)

The Portuguese Society of Pastures and Forages (SPPF) was born from a course on pastures and forages held in the National Plant Breeding Station of Elvas (where the headquarters of SPPF are located) in 1979. It was organised by the head of the Pastures and Forages Department, David Gomes Crespo, who was the first and founder member. According to Abreu et al. (1999), the structure established was that of a Scientific Society and was considered by the Government as a Service of Public Interest. It gathered inspiration from the British Grassland Society, the Association Francaise pour la Production Fourragére, …

Role Of The Grassland Society Of Bosnia And Herzegovina In Grassland Agriculture, S. Alibegovic-Gbic, M. Bezdrob

IGC Proceedings (1997-2023)

The biggest part of Bosnia and Herzegovina is covered with hilly and mountainous terrain, which, from the agricultural perspective, determines the manner of soil usage. Of all agricultural areas in Bosnia and Herzegovina, 55.49% are covered by grassland with that figure increasing to 79.14% in mountainous regions. Therefore, grassland agriculture and its cousin livestock production are the most significant part of the Bosnian economy. In the current situation natural grasslands are largely neglected and give a low yield of forage of low quality. Many areas are completely abandoned and have been gradually overgrown with weeds and bushes. Yet a special …

Institutions, Structures And Topics Of Grassland Research In Germany - From Science To Practice, Johannes Isselstein, H. Hochberg

IGC Proceedings (1997-2023)

In Germany, grassland covers some 30% of the agriculturally used land. It forms the basis of forage production in dairy and beef cattle husbandry as well as sheep and horse feeding. The intensification of grassland farming during the last fifty years was made possible through extended basic and applied research in all fields of grassland management. This included the improvement of forage species and varieties by plant breeding, the adaptation of botanical knowledge for the control of the botanical composition of permanent grass swards, the application of regular fertilisation, the improvement of the grazing management, the increased frequency of utilisation …

Comments On The Present Activity Of Czech Specialists In Grassland Cultivation, B. Cagaš

IGC Proceedings (1997-2023)

Unlike some other countries, there is no officially established forage crop or grassland society in the Czech Republic. This, however, does not mean that activity in this field is lacking. Several institutions are involved in the development of grassland research. These are predominantly: Grassland Commission of the Section of Plant Production of the Czech Academy of Agricultural Science, Forage Crop Commission of the Bohemian-Moravian Union of Plant Breeders, Bohemian-Moravian Association of Plant Breeding and Seed Production and Association of Grass and Clover Seed Growers. Members of these institutions are researchers and breeders of grasses and legumes, university lecturers from departments …

IGC Proceedings (1997-2023)

The American Forage and Grassland Council (AFGC) is a national organisation which has been in existence since 1968. Membership of AFGC is about 2,500. The membership of AFGC is divided into three main sectors: private, public and industry. The private sector has the largest membership (60%), and private members are usually producers that are engaged in some type of agricultural enterprise involving the use of forages. The public sector members (30%) are educators and other government agency personnel that work with the general public. The industry sector (10%) involves various companies that deal with the forage industry. The AFGC Board …

The Ulster Grassland Society, J. Morrison

IGC Proceedings (1997-2023)

Northern Ireland is a grass-growing region. Grassland accounts for 92% of the area farmed (excluding hill land). So the great majority of farm businesses in the Province are, at least partly, dependent on grass as a source of ruminant feed and grassland farming makes a major impact on the environment and landscape of the Province.

The Ulster Grassland Society was formed in response to a realisation that grass should be treated as a crop in its own right with potential to produce high output in higher rainfall areas which include Northern Ireland. Although there had been informal meetings held since …

The Role Of Grassland Societies In The West Of Scotland, G. E. D. Tiley

IGC Proceedings (1997-2023)

Local grassland societies were first established in the United Kingdom in the 1950s, under the guiding hand of the national, British Grassland Society, itself founded in 1946. In the west of Scotland two local societies were formed: 1) the South West Scotland Grassland Society in 1962, covering the former counties of Ayrshire, Dumfries, Kirkcudbright and Wigtown; and 2) the Central Scotland Grassland Society for Lanark, Stirling, Renfrew, Dumbarton and Clackmannan. The declared aim of these two societies was to promote good grassland farming in all its aspects amongst members and to identify opportunities for improved grassland management, all to the …

The Leucaena Network: A Grazier Advocacy Organisation Ensuring The Future Of A Valuable Forage Resource For Northern Australia, K. Mclaughlin, B. F. Mullen, H. M. Shelton

IGC Proceedings (1997-2023)

Leucaena leucocephala is a productive and sustainable forage tree legume for beef cattle production in northern Australia. Following a protracted period of research and development to overcome agronomic and social constraints, substantial adoption by graziers is now occurring (Mullen, these proceedings). However, a recent challenge has threatened future development, viz. the perception by some environmentalists that leucaena is an environmental weed. In addition, production-oriented support from public research and development organisations has diminished significantly over the past 20 years. The Leucaena Network (TLN) was formed in July 2000, primarily to counter the anti-leucaena movement, but has since developed as an …

The Lotus Newsletter: An Electronic Lotus Research Community, Mónica Rebuffo

IGC Proceedings (1997-2023)

The Lotus Newsletter (LN) was created by Dr. W.F. Grant (former editor) in 1971, integrating scientists working on diverse aspects of research on Lotus spp. The LN received further impetus under the editorship of Dr. P.R. Beuselinck, who shaped the electronic version (http://www.psu.missouri.edu/lnl/). The newsletter aims to provide a vehicle for the exchange of information where opinions, in addition to established facts, can be presented. One of the strengths of the LN has been the lead article for each issue and the extensive bibliographic listing published every year, which facilitates access to recent literature. As a …
