Learning through exchange about organic agriculture - case of Europe and Australia Organic Eprints
Sriskandarajah, N.; Mulley, R.; Christie, M.; Taji, A.; Wals, A.; Abbott, L.; von Fragstein und Niemsdorff, P.; Williams, R.; Langer, V.; Olsen, H.; Parvez, Q.; Ward, P.; Packham, R.; Scullion, J.; Daniel, H.; Kristiansen, P.; Galea, V..
LEAFSE is the catch word for an innovative program of exchange study for young Australians and Europeans, with organic agriculture as the focal point of their Masters level studies. Two years ago, the European Commission and the Australian Department of Education, Science and Technology (DEST) came up with the call for applications for a pilot project to support international mobility of tertiary students between the two continents. The grand aims set for the exchange included providing students with an international outlook and a range of perspectives, preparing them for the global marketplace, enable their understanding and empathy for different cultures and traditions and foster exchange of information. A number of us with an interest and an already...

Comparison of methods for measuring soil microbial activity using cotton strips and a respirometer Organic Eprints
Nachimuthu, G.; King, K.; Kristiansen, P.; Lockwood, P.; Guppy, C..
In order to develop a method of measuring the level of microbial activity in soil that is suitable for use by farmers, land managers, and other non-scientists, a simple method for determining soil microbial activity was evaluated and compared with two standard techniques. Soils sampled from vegetable farms in south east Queensland were incubated in the laboratory under controlled moisture and temperature conditions. Three methods were used to measure soil microbial activity, a respirometry method and two methods using the cotton strip assay (CSA) technique (image analysis and tensometer). The standard CSA method measured loss of tensile strength over a 35 day incubation period of buried cotton strips using a tensometer. The new CSA technique measured the...

Brassica cover crops for weed control in organic vegetable production Organic Eprints
Kristiansen, P.; Sindel, B.M.; Jessop, R.; Cerrai, D..
Cover crops (or green manures) are commonly used by organic vegetable growers for soil fertility building and other benefits including weed control. Brassica crops have been reported to control weeds in subsequent crops, usually attributed to the allelopathic effects of glucosinolates (GSL) in the brassica residues, although the effects are inconsistent. New brassica varieties with high GSL levels (Brassica juncea cv. Fumus and Raphanus sativus cv. Weedcheck) were tested in combination with mechanical weed control and another locally grown forage crop (Lolium multiflorum cv. Conquest) for their effects on weed growth during the pre-crop phase and subsequent weed and lettuce growth during the in-crop phase. The cover crops and bare fallow controlled weeds...

Australian Organic Market Report 2008 Organic Eprints
Kristiansen, P.; Smithson, A.; Monk, A.; Henryks, J..
Being four years since the publication of a similar research document, the Australian Organic Market Report (AOMR) 2008 is a landmark report for the organic industry. The report will be invaluable for monitoring and planning the industry development during a period of high growth. Delivering consistent data for benchmarking growth across the various sectors of the industry, it will be a key tool for decision making by organic producers and marketers, along with interested parties such as government and media, in assisting in understanding the nature, size and development of the organic industry in Australia. Supply chain development has been hindered over many years by a lack of basic information about volumes, seasonality, continuity and quality,...

Improving competitive ability of chickpea with sowthistle Organic Eprints
Cici, S.-Z.-H.; Kristiansen, P.; Sindel, B.M..
An experiment was conducted to examine the extent of root and canopy interference of chickpea (Cicer arietinum L.) with sowthistle (Sonchus oleraceus L.). Sowthistle was surrounded with either two or eight chickpea plants. There were different types of competition: no competition, shoot competition, root competition and full competition (root and shoot). The performance of sowthistle grown in full competition with two chickpea plants was the same as that grown with root competition only. Also, there were no significant differences between sowthistle grown with chickpea canopy shade and the control, where there was no competition. On the other hand sowthistle grown with eight neighbours was significantly suppressed in full, canopy or root competition.

Investigation of management practices and economic viability of vineyards for organic wine production Organic Eprints
Hassall, A.G.; Kristiansen, P.; Taji, A..
This paper reports the findings of two components of a research investigating the viability of organic wine grape production. Firstly the results of a survey of Australian organic wine grape growers’ management practices and secondly the first year findings of an experimental organic vineyard compared to an associated conventional vineyard. The survey found a heavy reliance on sulphur and copper sprays for powdery and downy mildew control. The experimental vineyard showed similar yields to conventional growing and in many cases higher sugar, though some increase in botrytis in organic Shiraz.

Overview of organic agriculture Organic Eprints
Kristiansen, P.; Merfield, C..
The acquisition of food, textiles and other resources from plants and animals has been a major concern for human societies, from the earliest days as hunter-gathers, through pastoral and swidden phases, to agrarian societies, with an associated trend away from nomadic to sedentary lifestyles. Yet as agricultural production intensified and expanded, the negative effects on the underlying resource base have also increased. The history of environmental damage caused by agriculture is well documented; impacts include air pollution from greenhouse gases such as carbon dioxide, methane, nitrous oxide; land degradation as a result of clearing, cultivation of sloping land and salinity; water pollution from fertilisers, pesticides, overuse and wetland draining; and...

Organic agriculture: opportunities and challenges Organic Eprints
Kristiansen, P.; Taji, A.; Reganold, J..
The organic movement may have gained a place in the spotlight of the mainstream media now, but it has not been like that for long. Since the 1950s, organic farmers operating at a grass roots level have devised, tested and shared production methods. They have codified a set of ideals into a pioneering best practice agricultural management system that addresses multiple community values. Niche markets have gradually been created, commonly based on trust and goodwill (formal certification did not begin until the 1960s and 1970s), and often using novel direct marketing strategies such as box schemes and community supported agriculture. After many years of consumers having to hunt around for their organic produce from several suppliers, perhaps directly from...

Crop agronomy in organic agriculture Organic Eprints
von Fragstein und Niemsdorff, P.; Kristiansen, P..
Organic crop husbandry is based on practices outlined in the various organic standards that have been developed and documented in many countries. The most widely recognised organic standards are those published by the International Federation of Organic Agriculture Movements (IFOAM 2002). Organic farming methods emphasise the use of internal on-farm inputs rather than externally sourced inputs to achieve essential soil fertility, nutrient management and plant protection goals. Self-regulation within an agroecosystem, multi-year management cycles and a focus on prevention rather than reaction, are key principles in organic farming that underpin organic plant production.

Australian Organic Market Report 2010 Organic Eprints
Mitchell, A.; Kristiansen, P.; Bez, N.; Monk, A..
This is the second report the Biological Farmers of Australia has commissioned to help industry bench mark the growth and health of its sectors. This report - another significant milestone in the two decade plus history of the rapidly developing Australian certified organic sector - builds the information base for industry to benchmark production and market value against past and current claims and estimates and will enable monitoring of future growth of the certified organic market in Australia and its farming and production base. In an industry characterised by operational diversity, this report allows for performance assessment by sector. The next publication in this series is planned in 2012 (biennial since the inaugural report in 2008) as a means of...
