Oilseed and protein crops grown in French organic farms: an overview of cultivation practices for sunflower and soybean

The development of organic agriculture in France was steady since 2010 but became stronger since 2014. Like other crops, the cultivated areas of organic soybean and sunflower doubled from 2014 to 2018. With a view to better characterize cultural practices in organic production, Terres Inovia and ITAB (in collaboration with Agence Bio) conducted in 2016 and 2017 a national farmers’ survey. These surveys reveal that sunflower was mainly cultivated over the same types of soil than in conventional production but were integrated in more diversified rotations. The main differences between organic and conventional systems concern sowing date and weed control. Organic sunflower was sown very lately compared to conventional one, which impacted the yield severely. Weed were controlled through ploughing, mechanical weeding and crop rotation and weed control was judged as satisfying by a major part of producers. Concerning soybean, a great difference is the use of irrigation which is almost systematic in conventional but concerned only 50% of cultivated area in organic production. Contrary to sunflower, soybean is integrated in short crop rotation, particularly when it was irrigated. This demonstrated the high profitability of soybean in organic systems. Like for sunflower, weed control done through ploughing, mechanical weeding, and crop rotation and weed control was also judged satisfying; nevertheless, criteria on harvest impurities are more severe and to respect them, organic farmers also use hand weeding in complement. These surveys will be reconducted over the years to be able to follow the changes of cultural practices over the years.

PROBLEMS AND PERSPECTIVES IN ORGANIC CULTIVATION OF CEREALS – OVERVIEW

In this study, an overview is made and a comparative analysis of articles, reports and materials dealing with organic farming of LWC, in the period 1970 to 2021 is performed. After analysing the literature, the following conclusions are made: Cereals occupy a particularly important place in organic farming, the main advantages of their cultivation are easy farming techniques, relatively easy mechanical weed control, disease control through rational crop rotation, opportunities for biological control of major pests. The soils in organic farming are better structured than those in conventional agriculture. Organic farming practices are related to improving soil properties, including the addition of organic matter to the soil, increasing the population of earthworms, biodiversity, soil fertility and more. Biological management provides a more stable soil structure. The larger pores observed in biological management have a beneficial effect on the physical properties of the soil, such as water flow and water capacity. The greater porosity of the soil provides a good habitat for soil microorganisms. Organic farming contributes to creating a better soil structure. Organic farming systems have traditionally been based on crop rotation. The aim of organic farming is to achieve a balance between crops that reduce soil fertility and crops that restore fertility. Crop rotation is the main tool that integrates the maintenance and development of soil fertility with various aspects of plant production in biological systems. Specialised selection programmes for creating varieties suitable for organic farming are too few due to the small number of users and high costs. The most common practise includes testing the suitability of conventional varieties in biological conditions, propagation and distribution of the best in the biological sector. Sowing norms directly control the sowing density, as well as the nutrient area of each plant. Changing sowing rates is also an excellent method for controlling weeding in biological fields. Concerning yields from organic and conventional agriculture, organic farms are less productive than conventional ones and their productivity is lower. But if environmental variables are taken into account, organic farms show the same or higher efficiency. A major problem facing organic farming in the future is the protection of fields from pollution by genetically modified organisms. An option for protecting biological fields is to maintain a buffer zone between the farm and the neighbouring conventional fields to prevent accidental contamination with GMOs.

Host-Guest Relationships in Non-Commercial Tourism Settings: WWOOFing in New Zealand

<p>This study investigates host-­guest elationships in a non‐commercial tourism setting within the context of WWOOF (World Wide Opportunities on Organic Farms) in New Zealand. WWOOF is a worldwide membership network of organic farms, and is comprised of non‐monetary exchange relationships between WWOOF hosts and guests (WWOOFers). It involves tourists offering their help with activities on these farms in exchange for accommodation and food. The purpose of this research is to examine WWOOF hosts and guests’ meanings and understandings of the host‐guest relationship and the dynamics that influence the nature of the WWOOF encounter. An examination of hosts and guests’ expectations and their subsequent effect on the encounter, and of personal outcomes, assist in making sense of the multiple roles of both parties. The study contributes to the limited research that explores non‐commercial host‐guest relationships in tourism. Through consulting literature on the commercial home, it builds on previous work on WWOOFing by focusing on hosts and guests’ perceptions rather than only one perspective. It gives voice to an under‐acknowledged group of hosts and tourists, who are not counted as contributors to economic development of tourism in New Zealand. The research was developed within a social constructivist paradigm. Using phenomenological methodology, in‐depth interviews with hosts and guests in New Zealand allowed for a thorough analysis of their personal narratives of the WWOOF experience, and the host‐guest relationships. Twenty‐eight interviews were conducted during June and July 2011 (some with two interviewees): resulting in data from 24 hosts and 15 WWOOFers. The findings suggest that WWOOF hosts and guests interact within work and social dimensions. The work dimension dictates that the guest offer help with work on the organic property in return for accommodation and food provided by the host. The social dimension demands interpersonal exchange and social bonds are developed. A model is presented, which demonstrates that host‐guest relationships in WWOOFing evolve and are constantly being negotiated and evaluated. Hosts and guests have multiple roles within the two dimensions: employer‐employee, host‐guest, (family) host‐family member, and friends. These roles are dependent on the level of formalisation of the encounter and the level of interpersonal connectedness. The encounter involves the host’s obligation to meet the needs of the guest and the guest’s obligation to adhere to implicit and explicit rules and guidelines determined by the host. Space and time are mostly shared within the host’s home or hosting space. The study shows that the relationships that occur are complex and multi‐faceted. The various dimensions, which are essential in creating closer, interpersonal relationships, are negotiated within various levels of the relationship. The aspects that influence the roles adopted in work and social spheres and the evolution of the relationship require an understanding of the temporal roles of hosts and guests, trust, shared values and stories, as well as work and social exchange elements.</p>

Mineral Concentrations in Bovine Milk from Farms with Contrasting Grazing Management

Thirty conventional and twenty-four organic dairy farms were divided into equal numbers within system groups: high-pasture, standard-pasture, and low-pasture groups. Milk samples were collected monthly for 12 consecutive months. Milk from high-pasture organic farms contained less fat and protein than standard- and low-pasture organic farms, but more lactose than low-pasture organic farms. Grazing, concentrate feed intake and the contribution of non-Holstein breeds were the key drivers for these changes. Milk Ca and P concentrations were lower in standard-pasture conventional farms than the other conventional groups. Milk from low-pasture organic farms contained less Ca than high- and standard-pasture organic farms, while high-pasture organic farms produced milk with the highest Sn concentration. Differences in mineral concentrations were driven by the contribution of non-Holstein breeds, feeding practices, and grazing activity; but due to their relatively low numerical differences between groups, the subsequent impact on consumers’ dietary mineral intakes would be minor.

Survival and Persistence of Foodborne Pathogens in Manure-Amended Soils and Prevalence on Fresh Produce in Certified Organic Farms: A Multi-Regional Baseline Analysis

Biological soil amendments of animal origin (BSAAOs), including untreated (e.g., raw or aged manure, or incompletely composted manure) and treated animal products (e.g., compost), are used for crop production and as part of soil health management. Application of BSAAO's must be done cautiously, as raw manure commonly contains enteric foodborne pathogens that can potentially contaminate edible produce that may be consumed without cooking. USDA National Organic Program (NOP) certified production systems follow the 90-or 120-day interval standards between applications of untreated BSAAOs and crop harvest, depending on whether the edible portions of the crops are in indirect or direct contact with the soil, respectively. This study was conducted to evaluate the survival of four foodborne pathogens in soils amended with BSAAOs and to examine the potential for bacterial transfer to fresh produce harvested from USDA NOP certified organic farms (19) from four states. Only 0.4% (2/527) of produce samples were positive for L. monocytogenes. Among the untreated manure and compost samples, 18.0% (42/233) were positive for at least one of the tested and culturable bacterial foodborne pathogens. The prevalence of non-O157 STEC and Salmonella in untreated manure was substantially &gt; that of E. coli O157:H7 and L. monocytogenes. Of the 2,461 soil samples analyzed in this study, 12.9% (318) were positive for at least one pathogen. In soil amended with untreated manure, the prevalence of non-O157 STEC [7.7% (190) and L. monocytogenes (5.0% (122), was &gt; that of Salmonella (1.1% (26)] or E. coli O157 [0.04% (1)]. Foodborne pathogen prevalence in the soil peaked after manure application and decreased significantly 30 days post-application (dpa). However, non-O157 STEC and L. monocytogenes were recovered from soil samples after 90 and 120 dpa. Results indicate that produce contamination by tested foodborne pathogens was infrequent, but these data should not be generalized outside of the specific wait-time regulations for organic crop production and the farms studied. Moreover, other sources of contamination, e.g., irrigation, wildlife, environmental conditions, cropping and management practices, should be considered. This study also provides multi-regional baseline data relating to current NOP application intervals and development of potential risk mitigation strategies to reduce pathogen persistence in soils amended with BSAAOs. These findings contribute to filling critical data gaps concerning occurrence of fecal pathogens in NOP-certified farming systems used for production of fresh produce in different US regions.

Empowerment of Women's Farmer Groups of “Kembang Lestari” in the Processing of Organic Waste from Various Fruit Peels as Liquid Fertilizer

Partners in the implementation of Community Service is the Kembang Lestari Peasant Women's Group located in Taman Village, Abian Semal Subdistrict, Badung Regency. This group has problems with the high price of chemical fertilizers and vegetable pesticides for the treatment of cultivated crops. This condition causes an increase in production costs and decreased profits. They have yet to find a solution to get cheaper, environmentally friendly plant-based fertilizers and pesticides that they will use in their organic farms in the future. Therefore, it is necessary to provide an alternative to organic fertilizers while serving as vegetable pesticides that are easy to make, cheap, and environmentally friendly. The alternative is an eco-enzyme that can be made from organic waste in the form of fruit peels. Eco-enzymes have the same benefits as liquid fertilizers, compost, anti-bacterial, midges, and disinfectants. Women's Farmer Groups of Kembang Lestari are given knowledge of eco-enzymes and their benefits, how to make and how to apply them to plants. The methods carried out in the implementation of this activity are by interviewing, face-to-face, counseling, and practice methods directly. First, the authors held general counseling on what an eco-enzyme is, its benefits for plants, and environmental sustainability. Second, the authors provide hands-on training in the manufacture of eco-enzymes and how to implement them and conduct several evaluations to ensure farmers can make eco-enzymes independently and see what percentage of the increased production and increased profits earned by the farmer group after the implementation of these eco-enzymes. Third, it motivates farmers to keep using eco-enzyme fertilizers continuously in cultivating crops.

Land use and soil quality in peri-urban farms in Southern Brazil

Small family farms constitute a major part of land use in the surrounding regions of Brazilian cities, as these farms not only contribute to the food supply, but also help conserve rural landscapes and improve environmental services. This study evaluated agricultural impacts on soil quality in seven family farms in Porto Alegre municipality, Rio Grande do Sul state, RS. Selected production units (PUs) were managed as conventional or organic farms, producing horticultural crops, fruits and pastures, besides native forests. Soil samples were collected from representative areas for five use and management types, under disturbed and undisturbed conditions, at 0–20 cm depth. Physical and chemical attributes were analyzed, comparing the effects of types of land use. Data analysis showed that more affected attributes were soil density, macro and microporosity, phosphorus content, pH and electrical conductivity. Macroporosity, phosphorus, zinc and cooper contents are the greater threats to soil quality. Horticulture, under both agroecological and conventional production systems caused major changes compared to natural conditions.
