“…From an agri-food chain perspective, the methodology also allows us to look at the subject holistically rather than in a particular way (individual links in the chain). Most agri-food chain sustainability assessment studies primarily focus on improving individual links rather than the agri-food chain as a whole; therefore, they are not interconnected [25,26] and, thus, cannot understand the chain's structure, external conditions, and internal processes. Petit et al stated that sustainability assessment needs to be conducted throughout the whole chain, taking into account all aspects of sustainability [24].…”

“…Given the characteristics of agri-food chains, these systems are recognized as being highly complex [24] and, consequently, difficult to manage. Most studies on agri-food chain sustainability assessment are predominantly focused on agriculture production [25,26], whereas some are trying to assess the sustainability of an entire agrifood chain [27,28]. Most of these studies are primarily sector-focused, aiming to improve individual links, not the agri-food chain as a whole, and/or their analysis does not assess all three pillars of sustainability.…”

‘Multi-SWOT’ Multi-Stakeholder-Based Sustainability Assessment Methodology: Applied to Improve Slovenian Legume-Based Agri-Food Chains

Assessing the sustainability of agri-food chains is challenging for several reasons. It should account for the impacts on environmental, social, and economic wellbeing simultaneously, considering both the individual links in the chain and the chain as a whole. The primary aim of this study is to assess the conditions for meeting the sustainability criteria of a legume-based agri-food chain in Slovenia. Therefore, a quantitative sustainability assessment methodology was developed, using a multi-stakeholder approach, which upgraded the traditional SWOT (strengths, weaknesses, opportunities, and threats) analysis. Our approach, called ‘Multi-SWOT’, aggregates the SWOT table inputs identified by stakeholders into factors, themes and focus areas, according to their importance for the agri-food chain, for each sustainability pillar, and links in the chain. By accounting for the relative number of incentives (beneficial factors) and barriers (constraint factors) we identified those factors that enhance the sustainability of the Slovenian legume-based agri-food chain and the factors jeopardising it. The incorporation of multi-stakeholder perspectives presents an innovative approach that adds value to a standard SWOT analysis. The study serves as a guide to help decision-makers better understand the multidimensionality of sustainability and identify effective activities to support and strengthen the current legume agri-food chain in Slovenia.

Producing of safe food from alkaline sandy soils under high rates of chemical fertilization is a serious concern in Egypt. Compost and vermicompost can improve soil fertility and crop production, but their application has not been well evaluated in zucchini (Cucurbita pepo L.) cultivation. This study aimed to determine the effects of compost and vermicompost on the yield, nutrient uptake of zucchini as well as on soil properties under field conditions. Four fertilization treatments, including a control without fertilization (CO), chemical fertilizer (CF), compost (CT), and vermicompost (VC) were arranged in a randomized complete block design with five replications. The results showed that CT and VC application significantly increased the yield of zucchini by 17 and 53%, respectively, in comparison with CF treatment. In addition, CT and VC treatments significantly increased the soil organic matter, soil availability of NPK compared with those in the CO and CF treatments. The application of the CT and VC amendments increased the N, P and K uptake significantly as compared to the CO and CF treatments. The highest values of N, P and K use efficiency were found in the CT treatment. The highly significant and positive correlation was found among different soil properties and zucchini traits. CT and VC are crucial for increasing productivity, improving fruit quality, and yield of zucchini fruit and can be used as an alternative to chemical fertilizers for zucchini cultivation.

“…Soils when not properly managed or used beyond their support capacity, suffer losses in the quantity and quality of organic matter and consequently reduce the productivity and physical stability (Ziech et al 2014; Mandal et al 2021;Gholkar et al 2022). Between the need to reduce the pollution load generated in agricultural processes, the depletion of mineral sources, and the continuous and increased demands for food and fertilizers, an important effort in research is now driven to understand and seek environmentally viable solutions to address these issues.…”

Characteristics of an acid soil cultivated with Uruchloa brizantha cv. Marandu were evaluated in relation to two types of fertilization: a conventional one, chemical based on nitrogen and potassium, and a biological one, based on microalgae biomass. The results were compared among three treatments: control, conventional, and biological fertilization, with seven replications each. The study evaluated microalgae community, total carbon and nitrogen contents, mineral nitrogen, and enzymatic activity. Chlorella vulgaris showed the highest organism density, which can be explained by its rapid growth and high resistance. The highest species diversity was detected in the control 1,380,938 org.(cm3)−1 and biological 1,841,250 (org.(cm3)−1 treatments, with the latter showing a higher density of cyanobacteria, especially Pseudanabaena limninetica with 394,554 org. (cm3)−1. The soil treated with chemical fertilization showed higher nitrate (9.14 mg.NKg− 1 NO3−-N) and potassium (52.32 mg.dm− 3) contents. The highest levels of sulfur (21.73 mg.dm− 3) and iron (96.46 mg.dm− 3) were detected in the biological treatment. The chemical treatment showed higher activity of the enzymes acid phosphatase, acetilglucosaminidase, and sulfatase, while α-glucosidase and leucine-aminopeptidase stood out in the biological treatment. Soil properties were not significantly affected by the treatments. The use of microalgae biomass derived from wastewater treatment from milking parlors was evaluated and presented as a promising fertilizer for agriculture, following the line of recovering nutrient-rich wastes. In this sense, although many challenges need to be overcome, the results suggest that microalgae-based fertilizers could lead to low-impact agriculture.
