The Study of Supply and Demand of Organic Products in the European Union and Serbia

One of the phenomena that marked 20th century is rapid technology progress. This process did not avoid food production and processing. Thanks to rapid development of technology, there has been a development of conventional food production, as well as appearance of genetically modified food. As a consequence of this trend, as well as the concern among some part of human population for their health, we had the return to natural food production in the form of the development of organic food production. One of the characteristics of organic food market in the European Union is the constant growth of demand for this product group, and insufficient quantities of organic products available in this market. These information led to the conclusion that organic food represents an opportunity for less developed countries, i.e., that countries like Serbia can manufacture and sale these products on the market with the highest purchasing power in the world--the European Union market. In this paper, the characteristics of demand for organic foods in the European Union were presented, then it was explained in detail why are these products export chance of Serbia, as well as reasons why is the export of organic food from Serbia to the EU very low at the time being. At the end, some recommendations that could help Serbia to increase export of organic product to EU countries were proposed.

Construction of Characteristic Marketing System of Organic Agricultural Products——A Case of Caijia wa Base

At present, food safety and agricultural pollution arouse public attention. Developing organic agriculture, therefore, is a feasible approach to solve related problems. Caijia wa is a base of organic agricultural products of Miyun County in Beijing. Based on the experience of farm management of Taiwan, Caijiawa＇s char- acteristics were explored. Customer requests were collected and analyzed to find growth space of new market. To establish marketing system for Caijia wa Base, three questions should be settled at the very begining. The questions are as fol- lows： Who are the customers to be confronted with？ What＇s kind of product or service can we provide？ What are the causes that customers willing to pay a prod- uct at higher price？ On basis of experience in Taiwan and local characters, the marketing system in Caijia wa Base can be concluded, including segmentation of market, diversification of marketing channel, close contact with clients and flexibility of price system. The pattern of omni-directional, muti-level and wide-ranging cooper- ation has been improved continuously. Finally, marketing system could integrate with social responsibility and sustainable development. Some measures about the marketing system have been proposed, which are believed applicable to other bases of organic agriculture.

Long-term organic and inorganic fertilizations enhanced basic soil productivity in a fluvo-aquic soil

The improvement of soil productivity depends on a rational input of water and nutrients, optimal field management, and the increase of basic soil productivity（BSP）. In this study, BSP is defined as the productive capacity of a farmland soil with its own physical and chemical properties for a specific crop season under local field management. Based on 19-yr data of the long-term agronomic experiments（1989–2008） on a fluvo-aquic soil in Zhengzhou, Henan Province, China, the decision support system for agrotechnology transfer（DSSAT ver. 4.0） crop growth model was used to simulate yields by BSP of winter wheat（Triticum aestivium L.） and summer maize（Zea mays L.） to examine the relationship between BSP and soil organic carbon（SOC） under long-term fertilization. Five treatments were included：（1） no fertilization（control）,（2） nitrogen, phosphorus and potassium fertilizers（NPK）,（3） NPK plus manure（NPKM）,（4） 1.5 times of NPKM（1.5NPKM）, and（5） NPK plus straw（NPKS）. After 19 yr of treatments, the SOC stock increased 16.7, 44.2, 69.9, and 25.2% under the NPK, NPKM, 1.5NPKM, and NPKS, respectively, compared to the initial value. Among various nutrient factors affecting contribution percentage of BSP to winter wheat and summer maize, SOC was a major affecting factor for BSP in the fluvo-aquic soil. There were significant positive correlations between SOC stock and yields by BSP of winter wheat and summer maize（P〈0.01）, and yields by BSP of winter wheat and summer maize increased 154 and 132 kg ha^（–1） when SOC stock increased 1 t C ha^（–1）. Thus, increased SOC accumulation is a crucial way for increasing BSP in fluvo-aquic soil. The manure or straw combined application with chemical fertilizers significantly enhanced BSP compared to the application of chemical fertilizers alone.

Organic matter accumulation in lacustrine shale of the Permian Jimsar Sag,Junggar Basin,NW China

The lacustrine organic-rich shale in the Permian Lucaogou(LCG)Formation of the Jimsar Sag,Junggar Basin,is one of the main shale oil plays in China.In this paper,geological and geochemical research techniques were employed to evaluate the geochemical variability of the lacustrine shale and the pro-duction of organic matter and its preservation conditions.The LcG Formation is characterized by its complex mineral compositions and a wide range of organic matter richness and quality.The presence of high proportions ofβ-carotane and C2g steranes,indicates that the organic matter mainly originated from phytoplankton and aquatic algal-bacterial organisms,especially cyanobacteria.This study found that the productivity of the Lower LCG Member(P2li)was highest,and the Middle LCG Member(P_(2)l_(2))was the lowest.During the deposition of the Lower LCG Member,the lake's bottom water was predominantly a reducing environment,and the degradation of organic matter was largely a result of bacterial sulfate reduction.During the deposition of the Middle and Upper LCG members,the lake's bottom water was mainly oxidizing,and the degradation of organic matter was likely to be caused by aerobic processes.Based on a comprehensive analysis of the origin and production of organic matter,as well as its depo-sitional environment and preservation conditions,two organic matter accumulation models were pro-posed to explain the distribution of the organic-rich shale.In model A,the high influx of volcanic ash released nutrients and brought abundant sulfate into the water,the accumulation of organic matter was mainly controlled by the preservation of organic matter,which was mainly controlled by BsR.In the model B,the influx of volcanic ash was small,organic matter was mainly degraded by oxygen and the accumulation of organic matter is mainly determined by the production of organic matter.

Design and Experiment on Environment Friendly Type of Production Equipment of Organic Fertilizer by Chicken Manure

In accordance with current problems such as odor pollution,long production period,consumption of a large amount of manpower and so on existing in chicken manure fermentation ,an environment friendly type of chicken manure fermentation device is designed. The key parameters of the equipment are resonance activated tube and fermenting cellar. Resonance activated tube makes the activated water,which could improve obvi- ously the biodegradation rate of chicken manure. The aerator could provide enough oxygen to microbes,and the agitator could make oxygen evenly distributed across the chicken manure in fermenting cellar. The test shows that this equipment is high-efficiency,and only takes 7 days to make the chicken manure achieve the decomposed requirement. The organic matter content of composted chicken manure is 91.2%,C/N ratio is 18.8, MPN is 0.04, mortality of ascarid egg is 99.6% ,concentrations of NH3 and H2 S are 4.20 and 1.58 mg/m3, furthermore ,there is no offensive smell in the fermenting cellar. Therefore,the study can provide a pollution-free, high-efficiency, manpower saving fermentation equipment for organic fertilizer production by chicken manure in agriculture area.

Facilitating Trade in Organic Food Products： The Case of India and ASEAN

This paper discusses how India and Association of Southeast Asian Nations （ASEAN） countries can increase their trade in organic food products. With rise in demand for organic food products globally, India and select ASEAN member countries have become key producers and exporters of organic food products. Trade in organic food products is governed by regulations, standards, certification and accreditation procedures, which enables differentiation of organic products from conventional products. Organic standards ensure premium price for the farmers and producers, while consumers are assured of authenticity of the product. Standards can act as a barrier to trade as regulations governing organic food products can vary across countries. Some countries are also in process of developing regulations. This paper discusses the role of different multilateral agencies in designing standards and how countries can address issues of difference in standards by signing unilateral and bilateral equivalence arrangements, trade agreements and harmonizing their standards within regional groups. It also discusses how India and ASEAN countries can align their domestic regulations in line with the global best practices so that they can sign equivalence arrangements to enhance their exports. The paper concludes that measures such as coming up with a comprehensive definition of ＂organic＂, having a uniform standard for organic products encompassing domestic market and trade, having a single nodal agency for both domestic market and exports, developing organic clusters and reducing the cost of third-party certification will help enhance trade in India and ASEAN, and enable these countries to access third country markets.

Direct Marketing and Consumer Trust in Organic Food Products： Vilnius （Lithuania） Case

The market of organic food products has a continuous upward trend though the growth rate and sale channels in individual countries are rather different. This research aims to identify the key factors that influence consumers＇ choice to buy organic food products in Lithuania focusing on the consumer trust in the quality and the most acceptable marketing channels. In order to get the necessary information, the residents of Vilnius （the capital of Lithuania）, as having the greatest potential for the organic food market in the country, were interviewed. The analysis of collected data was done using the methods of mathematical statistics and comparison of relative frequencies. The results of this research prove the increasing consumers＇ interest in organic food products. The majority of consumers consider these products to be healthier, better-tasting and fresher. Only about a third of the purchasers （usually buying frequently） can see differences between organic and non-organic products, therefore, there is a problem to distinguish organic food from conventional products and, consequently, remains a possibility to cheat the consumer. An additional quality control and direct sales from known and familiar farmers might increase trust in the quality of organic food products. So far, supermarkets are the most important place to buy organic foods, however, the greater consumer confidence in the quality of organic products bought at farmers＇ markets and the acceptance of the majority of purchasers to buy organic food products directly from the farmers suppose the need to develop a direct marketing system.

Evaluation of the Efficacy of Essential Oil Extracts in the Control of Termites (Isoptera: Termitidae) in Cashew Orchards in Badikaha (Côte d’Ivoire)

Cashew tree has gradually moved from a purely ecological aspect to a socio-economic one, due to the marketing of its nuts. But production per area, estimated at between 424 and 547 kg/ha, remains low, in contrast to India (2nd largest producer) and Vietnam (3rd largest producer), whose yields range from 1000 to 1500 and 2000 to 2500 kg/ha respectively. This low yield is due to a number of factors, among which insect pests are the most damaging. Among these insects, termites are considered to be one of the main pests of cashew trees. The general objective of this study is to contribute to termite management through the use of bioinsecticides, an alternative to the use of chemicals in cashew orchards. Five (5) biological products were tested: Limocide, Carapa oil, Neem oil, Kitana and Kaskara. Among them, two products proved effective, with a mortality rate of over 50%. These were Limocide, whose LC50 was obtained in 24 h at a dose of 3.6 g/ml and 3.1 g/ml , giving a mortality rate of 57.66% ± 4.04% and 51.33 ± 2.08 respectively , and Carapa, at a dose of 4.5 g/ml, with an estimated mortality rate of 52.33% ± 1.52%. Such results have demonstrated the potential application of Limocide and Carapa biopesticides to sustainably control termites in cashew orchards of Côte d’Ivoire.

The national problems in this context have been specified, and recommendations were developed based on observations and examinations of ISO 17065:2012 international standard.

Developmental Differences, Yield and Late Blight （Phytophthora infestans）Infection of Potato Plants Grown under Organic and Conventional Systems

In the years 2008-2010, an experiment was conducted Phytophthora infestans under organic and conventional production on four potato cultivars differing in maturity and resistance to systems. During the growing season, plant growth was evaluated by measuring plant height, stem number, leaf and stem biomass and leaf area index （LAI）. Photosynthetic active radiation （PAR） absorption and leaf chlorophyll content were also measured. The rate of late blight development, tuber yield, tuber size, and harvest index was assessed. There were significant differences between the two production systems in the most studied parameters. Plants growing in the organic system were characterized by reduced plant development compared to plants growing in the conventional system. As a result of lower plant growth, tuber yield was reduced by 22% and tuber size was smaller. Harvest index did not differ significantly between production systems. A positive effect of the reduced development of aboveground plant parts in the organic system was later appearance of the first symptoms of late blight and slower spread the disease.

Anatomy of the 3D Innovation Production With the Cobb-Douglas Specification

This paper focuses on verifying the relevance of two theoretical propositions and related empirical investigation about the relationship between creativity and entrepreneurship. It draws upon a creativity process that considers three ＂dimensions＂ or ＂disciplines＂ （3D） critical for creative organizations--within discipline expertise, out of discipline knowledge, and a disciplined creative process. The paper first explores the Cobb-Douglas production function as a relevant tool for modeling the 3D creative process. The next part discusses the 3D process as a production function, which is modeled following the well-known Cobb-Douglas specification. Last, the paper offers implications for future research on disciplined creativity/innovation as a method of improving organizations＇ creative performance. The modeling shows that labor and investment can readily enter into the 3D creativity process as inputs. These two inputs are meaningful in explaining where innovation outputs come from and how they can be measured, with a reasonable theoretical decomposition. It is not true that the more capital investments in the creativity process, the better the level of innovation production, but firm＇s human resource management and expenditures should pay attention to optimal levels of capital and labor stocks, in a combination that helps reach highest possible innovation output.

Dynamics of the Austrian Food Market: Application of Lotka-Volterra Differential Equations

The organic food market has become an important part of food industry. We analyze sales data from Austria for 2014 to 2020 of 124 products from 25 product groups in six categories, each in conventional and organic form. We fitted their market shares by means of a modified Lotka-Volterra model with constant coefficients. When only organic and conventional products were compared, a significant increase in market shares was observed for 15 of 25 organic product groups, indicating a continuing growth of the organic food market. The typical Lotka-Volterra dynamics was a predator-prey dynamics with an organic product (group) predating on conventional products that were in symbiosis.

Investigation of low-molecular weight organic acids and their spatiotemporal variation characteristics in Hongfeng Lake,China

The identities and concentrations of low-molecular-weight organic acids （LMWOAs） were determined by ion chromatography throughout a 20-m water column in Hongfeng Lake, China. The spatiotemporal variations of LMWOAs and their contributions to dissolved organic matter （DOM） in a research period of 24 hr were also investigated. The results demonstrated that five LMWOAs （lactic, acetic, pyruvic, sorbic, oxalic acid） were detected, and their total concentration and proportion in DOC were 6.55 μmol/L and 7.47%. Their average levels were 2.50, 0.65, 2.35, 0.96 and 0.09 μmol/L, respectively. LMWOAs were higher during daytime （10：00-18：00 on Jun 13, 2008） than nighttime （21：00-6：00 the next morning）, in particular 4.99 μmol/L high in the epilimnion （ 1 m water depth）, reflecting the fact that direct import from terrigenous sources and photochemical production from humic materials were dominant during LMWOAs＇ origin and accumulation. The same factors caused LMWOAs to be 0.63 μmol/L in the epilimnion higher than in the hypolimnion. The rapid decrease of total organic acid （TOA） up until 18：00 mainly resulted from bio-uptake and mineralization in the hypolimnion （〉1 m water depth）. Pyruvic acid increased with time in the epilimnion and decreased in the hypolimnion, largely related to the two contrary processes of continuous degradation and synthesis of macromolecular organic matter during life materials＇ cycle mediated by organisms. Simultaneously, plankton behavior and thermal stratification played a pivotal role in LMWOAs＇ behavior in the water column, causing decreasing and increasing profiles. The distribution of LMWOAs represents an interesting resource for biogeochemical research of DOM in aquatic ecosystems.

Biodiversity,current developments and potential biotechnological applications of phosphorus-solubilizing and-mobilizing microbes:A review

As one of the most important and essential macronutrients next to nitrogen,phosphorus(P)is important for plant development,but it is the least mobile nutrient element in plant and soil.Globally,P is mined from geological sediments and added to agricultural soils so as to meet the critical requirements of crop plants for agronomic productivity.Phosphorus exists in soil in both organic and inorganic forms.The various inorganic forms of the element in soil are salts with calcium,iron,and aluminum,whereas the organic forms come from decaying vegetation and microbial residue.There is a huge diversity of plant microbiomes(epiphytic,endophytic,and rhizospheric)and soil microbiomes that have the capability to solubilize the insoluble P and make it available to plant.The main mechanism for the solubilization of inorganic P is by the production of organic acids,which lowers soil pH,or by the production of acid and alkaline phosphatases,which causes the mineralization of organic P.The P-solubilizing and-mobilizing microorganisms belong to all three domains,comprising archaea,bacteria,and eukarya.The strains belonging to the genera Arthrobacter,Bacillus,Burkholderia,Natrinema,Pseudomonas,Rhizobium,and Serratia have been reported as efficient and potential P solubilizers.The use of P solubilizers,alone or in combination with other plant growth-promoting microbes as an eco-friendly microbial consortium,could increase the P uptake of crops,increasing their yields for agricultural and environmental sustainability.
