This study conducted an investigation into the effects of fruit type and cultivation practices (organic and conventional) on soil characteristics and soil arthropod communities within apple, blueberry, grape, peach, and pear orchards. The collection of soil arthropod communities was achieved through the utilization of pitfall traps, with concurrent measurements taken for soil moisture content, electrical conductivity, and temperature. The findings of this study unveiled substantial impacts attributed to fruit type and cultivation practices on soil characteristics. Specifically, within organic apple orchards, discernibly higher levels of soil moisture content, electrical conductivity, and temperature were observed when compared to their conventional counterparts. The investigation into soil arthropod communities yielded a total of 1,527 individuals, classified in to five phyla and 15 orders. The range of abundance, species richness, and diversity indices varied across conventional and organic orchards. Cultivation practices were found not to exert a significant influence on soil arthropod community characteristics. However, Non-metric Multidimensional Scaling (NMDS) analysis indicated a significant differentiation in soil arthropod community structure based on cultivation practices. This study underscores the importance of considering vegetation structure and environmental characteristics that may influence soil arthropod communities comprehensively when assessing the impact of cultivation practices on soil arthropods. Furthermore, it emphasizes the need to account for both the characteristics and structure of soil arthropod communities in understanding the implications of cultivation practices on these organisms.

초식, 포식, 분해 등 생태학적 서비스를 제공하는 지표 배회성 절지동물은 사과원의 중요한 구성 요소이며, 이들의 군집에 영향을 미치는 잡초는 유기재배와 관행재배 사과원에서 다르게 관리된다. 잡초 관리와 관련된 과수원 관리가 지표 배회성 절지동물의 풍부도와 다양도에 미치는 영향을 평가하기 위해 3년간 연구를 수행하였다. 대부분의 절지동물은 상위분류군과 섭식 기능군으로 분류하였으며, 딱정벌레류는 종 수준으로 분류하였다. 지표 배회성 절지동물의 주요 우점군은 딱정벌레목으로 나타났다. 초식자와 포식자의 풍부도는 유기재배 사과원에서 높은 결과를 보였으며, 딱정벌레류의 풍부도와 다양도 또한 관행재배 과원보다 유기재배 사과원에서 높은 결과를 보였다. 거미목, 딱정벌레목 또는 딱정벌레류의 풍부도는 잡초 관리 빈도와 음의 상관관계를 보였다. 지표 배회성 절지동물은 농업 시스템보다 잡초 관리에 영향을 더 많이 받는 것으로 나타났다.

국내 563만 가구가 반려동물을 기르는 것으로 추정되며, 반려동물의 수는 지속적으로 증가하고 있다. 이와 동시에 유기동물도 급격하게 증가하고 있다. 농림축산식품부의 통계 자료에 의하면 2016년 89,000 마리가 유기되었다고 발표하였다. 이는 하루 244마리가 유기되고 있는 것이다. 유기동물의 증가와 더불어 정부에서 사용되는 처리 비용 또한 증가 하고 있으며, 원보호자를 찾거나, 재 입양을 가지 못한 반려동물의 경우 인도적 처리를 한다. 이는 안락사를 의미한다. 따라서 반려인에게는 반려동물의 입양경로와 애로점, 유기 동물 입양의사 및 사후처리과정 인지여부를 설문조사하였으며, 비반려인에게는 캣맘, 캣 대디에 대한 생각, 유기동물에 대한 생각 및 사후처리 과정에 대해 설문조사를 함으로써 반려동물 및 유기동물에 제도적 정비 및 선진화된 반려동물문화가 필요할 것으로 본다.

유기과수원은 풍부한 유기물이 존재하고 식생이 다양하며 화학농약을 사용하지 않아 생물상이 풍부한 특징을 가지고 있다. 본 시험에서는 국내 배, 사과 유기과수원에서 발생하는 저서성 절지동물을 채집하여 발생 분포를 조사하였다. 절지동물 의 채집은 사과(청송, 무주, 단양, 예천) 배(아산, 천안, 화성, 여주) 각각 4지역의 과수원에서 진행하였다. 또한 과수원내 생태적 보상공간의 효과를 알아보기 위해 청송, 예천 유기과수원내 10여 종의 초화류 식물을 이용한 초화류길을 조성하였으며, 이로인한 절지동물의 발생 차이를 일반예초구와 비교 조사하였다. 절지동물의 채집은 6월중순부터 10월초까지 핏폴트랩을 사용하여 이루어졌다. 에탄올, 글리세린, 증류수를 넣은 400ml 컵을 이용하여 핏폴트랩을 만들고 조사구마다 3개씩 설치하였 다. 조사가 이루어진 유기과수원의 절지동물을 분석한 결과, 잡식성 절지동물이 50.9%로 가장 높게 나타났고 기생성 24.6%, 부식성 23.5%, 포식성이 6.6%로 순으로 나타났다. 과수원내 초화류길을 조성한 구획에서는 무처리에 비해 22~28% 높은 개체수가 채집되어 생태적 관리에 따른 절지동물상의 변화를 확인할 수 있었다. 유기과수원의 식생을 적절히 관리한다면 과수원내 생물다양성을 높여 농업의 환경적 가치를 증대시킬 수 있을 것이다.

Although some skeptical views arguing that the impact of organic farming is quite limited to sustainable biodiversity, the organic agriculture has been generally accepted to have positive effects on various properties of soils not only on biophysical and ecological properties but also on biodiversity of the field. Therefore, this field investigation has been conducted to examine the effect of organic farming, relative to conventional agriculture, through a comparative investigations of the two systems for conserving local biodiversity of invertebrate animals. For this research, organic and conventional farming locations matched with both of a paddy field and a upland fields in Goesan-gun province (Chungcheongbuk-do, South Korea) were selected to compare the species richness of invertebrate biodiversity as follows: location OP (Organic Paddy field), location OU (Organic Upland field), location CP (Conventional Paddy field), and location CU (Conventional Upland field). Among 249 species collected, the numbers of species collected in the locations practicing organic farming were greater than the locations practicing conventional farming both in paddy fields (104 vs. 84 species) and upland fields (108 vs. 77 species). Changes in species richness can be shown in the selected locations depending on the agriculture system with organic (50 species) or conventional (44 species) farming systems in the paddy fields, similarly with organic (42 species) or conventional (35 species) farming in the upland fields, respectively. Our present research clearly shows that a wide range of taxa, including insects, spiders and other invertebrates, benefit from organic management through increases in abun-dance or species richness. It has been also identified that four orders (Hemiptera, Diptera, Hynemoptera, and Araneae) that are largely intrinsic to organic paddy field, and another three orders (Hemiptera, Coleoptera, and Araneae) that are particularly beneficial for organic crop field regime.

This study was conducted to compare the community structure and biodiversity of ground-dwelling invertebrates between conventional and organic paddy fields’s levees. Ground-dwelling invertebrates were collected using a pitfall trap every month for two years (2010-2011) in levees of conventional and organic paddy fields. The numbers of species and individuals were higher in organic paddy field than in conventional paddy field. For the pests, the treatment of insecticide and herbicide reduced the number of Delphacidae, and Chrysomelidae, but did not affect the other pests such as Chronomidae, Culicidae, Thripidae, and Aphididae. For the natural enemies, the treatment reduced the number of individuals of most of enemy's taxon (except only one taxonomic group, Ichneumonidae) in the levee of conventional paddy field.

This study was conducted to evaluate the nutritional value of locally produced organic agricultural by-products to substitute imported organic feeds for organic ruminant farming. Imported organic feeds (corn grain, soybean meal, soybean seed, oat grain, barley grain, wheat grain, buckwheat, sunflower seed meal) and byproducts (rice bran, grape seed meal, rice straw, soybean hull, soybean curd, rice hull, green kernel rice, and crushed rice grain) were analyzed for chemical composition and NDF, ADF, mineral, and amino acid contents and anti-nutritional factors. Dry matter, NDF and ADF contents in organic feeds were higher than those in conventional feeds. Especially, the 9.65% fat content of organic soybean meal was 6 times higher than the 1.95% fat content of conventional soybean meal. Fat contents of rice bran, grape seed meal, green kernel rice, and crushed rice grain were 25.66, 6.09, 3.57 and 1.59%, respectively. Protein contents of soybean hull and soybean curd were 14.68 and 19.87%, respectively, which are highest among organic by-products. Levels of aflatoxin in all feeds were below the safety level. Therefore, organic rice bran, green kernel rice and crushed rice as energy source, and soybean hull and soybean curd as protein source could partial replace imported feeds for organic ruminant farming.

This research was carried out to investigate invertebrate fauna with organic and conventional pear orchards, which used four collected methods; soil sampling for soil microorganism, pitfall, malaise, and black light trap for over ground species. Collected species were 37 species, 1,184 individuals in organic and 28 species, 501 individuals by soil sampling in conventional pear fields. Those were 38 species, 646 individuals and 29 species, 440 individuals by pitfall trap, 55 species 650 individuals and 47 species, 508 individuals by malaise trap, and 23 species, 201 individuals and 9 species, 42 individuals by black light trap. Collembola was collected 389 individuals in organic which was 5 times than in conventional in soil sampling. In pitfall trap, that was 183 individuals which was 3 times. The diversity indices of organic pear orchards were 1.956 in May, 2.638 in August and those of conventional was 1.426 in May, 2.011 in August in soil sampling. In pitfall trap, the dominant species were spiders, collembollan, and coleopteran. Among Coleoptera, indicator insects for the evaluation of agricultural environment suggested were Eusilpha jakowelewi as organic pear orchard and Anisodactykus punctatipennis and Pheropsophus jessoensis as conventional. Malaise trap was collected dominant species as Diptera and Hymenoptera of Braconidae and Ichneumonidae. The diversity indices of organic pear orchards were 2.952, 3.120, and 2.010 in pitfall, malaise and black light trap in over ground invertebrate sampling. The highest diversity was in malaise trap. The higher diversity indices, the lower dominance indices.

Organic farming is promoted financially in the Republic of Korea since 2000. The entire segment shows a very dynamic development since that time. Now, a large bouquet of measures are offered which target the promotion of organic farming. This article presents a study about the Task and Valuation on farm animal welfare for Organic Livestock. Among the supports are grants for organically managed livestock farm, investment incentives, the promotion of organic livestock husbandry, the promotion of producer co-operatives, the development of farm animal right index for animal health and animal welfare, publicity measures and measures to raise consumer awareness as well as the support of training, extension and research in the field organic livestock farming. Government must ensure that necessary incentives and sanctions are in place to maintain and improve animal welfare standards and they must be delivered appropriately. Animal welfare legislation provides essential protection for economy, environment, animals and society as a whole, must be properly observed.
