Tillage-Induced Changes in Soil Structure and Pore Space Distribution.
2026Durga Bastola · Murray State's Digital Commons (Murray State University) · United States (Kentucky)
This study evaluated the effects of contrasting tillage intensities on soil structural characteristics and pore space distribution across six agricultural systems at Pullen Farm in Murray, Kentucky. Soil samples were collected from low-disturbance no-till systems and high-disturbance conventional tillage systems to determine bulk density, total porosity, and soil water-holding capacity. Results showed that no-till systems maintained significantly lower bulk density and greater total porosity, while conventionally tilled systems exhibited increased bulk density and reduced pore space. This indicates that tillage-induced disturbance directly modifies soil structure and pore continuity, leading to reduced pore space and impaired water dynamics.

2026Jesús De la Rocha Illanes · Revista de Estudios Urbanos y Territoriales IBU · Mexico (San Cristóbal de Las Casas)
A qualitative, exploratory-descriptive study was conducted on four community urban gardens in San Cristóbal de Las Casas, Chiapas, Mexico, to understand how agroecological scaling occurs and what practices comprise it. The research found that agroecological scaling in these gardens is essentially horizontal and deep, occurring at a microsocial level, person-to-person, and intergenerationally; however, the vertical facet of this process appears to be weakened. Agroecological practices include collective/collaborative composting of organic matter, ecotechnology engineering, links with local socioeconomic and solidarity networks, digital presence, reintegration of agricultural ceremonies/rituals in the urban context, and collective actions against eviction attempts.

CompostOrganic cycleFood educationStraw cover increases garden soil microbial biodiversity
2025Emory Walker, Mara Welty, Emma Creviston, Jacob J. Adler · Urban Agriculture & Regional Food Systems · United States (Lafayette)
This project examined how straw cover affects the soil microbiome of a community garden, using EcoPlate carbon-source utilization analysis and 16S rRNA sequencing on samples from the Erie Street GrowLocal community garden in Lafayette, Indiana. Straw cover increased soil moisture content and significantly increased bacterial alpha diversity, with a shift toward carbohydrate preference, though beta diversity showed no difference between conditions. The authors conclude that straw coverage can improve soil microbial biodiversity and moisture, potentially benefiting yields and food quality for communities.
BiodiversityOrganic cycleCommunityMarket Yield of Relay Cropped Leafy Greens in Urban Agriculture Production Systems
2025Leigh Whittinghill, Megan Goins, Shawn Lucas · HortScience · United States
This study examined how two urban agriculture production systems (raised beds and container plots) and four nutrient-management treatments (conventional fertilizer, organic fertilizer, peat-and-compost plus organic fertilizer, and peat-and-compost only) affected yields of relay-cropped leafy greens across the 2018–2019 seasons. Significant differences between systems and treatments were few and inconsistent, but results suggest small plastic-pool containers are suitable for urban greens production and tentatively support organic fertilizers and compost as a nutrient source.

2025Sofía Aguado, Helena Cotler, Marta Astier, Alejandro Padilla‐Rivera · Circular Economy and Sustainability · Latin America
This literature review examined methodologies applicable to municipal composting systems linked to urban agricultural production, with a specific focus on the Latin American context. It revealed a lack of structured methodologies to assess the circularity of municipal organic waste management systems and their connection with urban agriculture, particularly in heterogeneous contexts like Latin American cities, despite numerous existing evaluation methods. Life Cycle Assessment (LCA) is commonly used but often prioritizes environmental impacts, neglecting social, economic, and circularity dimensions.

2024Carolyn A. Zeiner, Maria N. Kisch, Ethan D. Lynch, Paliza Shrestha, Gaston E. Small · Urban Agriculture & Regional Food Systems · United States (Minnesota)
This study characterized soil microbial activity profiles—microbial abundance, soil respiration, extracellular enzyme activity, and crop yield—in an urban agriculture system in Minnesota, USA, using recycled organic compost (manure or municipal) at high or low rates. A high application rate of manure compost supported 6–10× higher basal respiration, and microbial biochemical function predicted 50% of the variability in bell pepper yield while community size alone was a poor predictor, indicating that "more is better" does not necessarily hold for soil microbial health.
