This study explores agroecological practices designed to improve soil quality and crop yield in small-scale agriculture, focusing on soil inoculation with beneficial bacteria over conventional fertilizers. Conducted at the SZIA Agroecological Garden MATE in Gödöllő, Hungary, the research utilizes 12 plots to evaluate different conservation tillage methods, including minimum and no-tillage, with and without microbial inoculation. Commenced in 2022, this study centers on potato cultivation (Solanum tuberosum L.) and includes comprehensive chemical and physical analyses of soil and harvested potatoes, alongside continuous monitoring of growth. Statistical analysis using One-way Anova in R revealed p-values predominantly above 0.05, indicating no significant differences across most parameters, though variations in soil plasticity and pH (KCl) were noted. Results suggest that substantial treatmeent differences may require a longer observation period. Notably, plots with microbial inoculation exhibited higher harvest weights and tuber sizes compared to control plots. Additionally, trends and interactions were found between weed abundance, total harvest, and plant height. The findings indicate that the benefits of integrated agroecological practices, including conservation tillage, may take time to materialize, emphasizing the necessity for extended observation. This research lays the groundwork for future studies, underscoring the importance of patience in achieving improvements in soil health and crop quality through sustainable agricultural methods.

This study examines the impact of agroecological practices on soil quality and crop yields in small-scale farming, focusing on the combination of microbial soil inoculation, crop rotation, and conservation tillage methods. Conducted at the SZIA Agroecological Garden MATE in Gödöllő, Hungary, the experiment used 12 plots, employing various conservation tillage techniques, including soil loosening with and without microbial inoculants, as well as no-till systems with and without inoculation. Six of the plots were inoculated with beneficial bacteria to enhance nitrogen fixation, phosphorus mobility, nutrient solubilization, phytohormone production, and pathogen suppression. In 2024, peas (Pisum sativum L.) were planted following potatoes in a small-scale market-oriented crop rotation, with the continuous monitoring of crop performance and soil characteristics. This ongoing study focuses on evaluating the long-term effects of crop rotation on key agricultural parameters, aiming to optimize practices over time. Statistical analysis (one-way ANOVA) revealed no significant differences across most parameters (p > 0.05), except for total sugar content (p < 0.05), which aligns with expectations given the limited tillage prior to the study. The standard significance level of p < 0.05 was used to balance error risks, ensure adequate statistical power, and maintain consistency with established agricultural research practices. However, the study trends indicated potential long-term benefits, particularly in plots with microbial inoculants, where pea yield and pod size showed improvement compared to non-inoculated and control plots. Microbial inoculants may show long-term effects, as they gradually improve soil health, support microbial communities, and enhance nutrient cycling, which takes time to become noticeable. These findings highlight the potential advantages of combining conservation tillage with microbial inoculants, suggesting that this combination could foster enhanced soil health and productivity over time. The novel setting of this study underscores the importance of long-term monitoring to fully capture the benefits of agroecological interventions, emphasizing their role in achieving sustainable agricultural practices and improving small-scale farming outcomes.

Modern agriculture faces increasing pressure to maintain productivity while reducing soil degradation, chemical inputs, and ecological footprint, making biologically based soil-improvement strategies highly relevant. This study examined whether microbial inoculation, combined with conservation tillage practices (loosening and no-tillage), can enhance soil physical quality during pea (Pisum sativum) cultivation in an agroecological market garden in Hungary. A 2 × 2 factorial field experiment was established, testing tillage (loosening vs. no-tillage) and microbial inoculation (with vs. without) in a randomized design with three replications per treatment (12 plots total). A single microbial application was performed prior to planting using a consortium of Rhizobium spp., Ensifer spp., Pseudomonas spp., and Bacillus spp. The research focused on (I) soil penetration resistance, (II) soil moisture dynamics, and (III) infiltration capacity, with most parameters measured before and after planting. Microbial inoculation significantly reduced penetration resistance under both tillage systems and influenced soil moisture behavior, indicating improved soil structure and water retention. Infiltration rate did not change significantly within the study period. Overall, the results demonstrate that microbial amendments can rapidly improve key soil physical properties, offering a practical, nature-based strategy for resilient, low-input farming systems.
