Produção de húmus líquido com diferentes solventes e proporções, para uso na arborização e agricultura urbana e periurbana
2022Eleano Rodrigues da Silva, Sônia Sena Alfaia, Marta Iria da Costa Ayres, S. G. A. de Sousa, Robert Corrêa Rodrigues · Concilium · Global
This study investigated the production of liquid humus (HL) using different solvents and proportions for use in urban and peri-urban afforestation and agriculture. Nutrient content and concentrations, yields, and the odor and appearance of the residue were analyzed. Results indicated that the odor in all HL samples was very mild, practically odorless, allowing their use in urban areas. From the chemical compositions of the analyzed products, it was inferred that HL has potential for use in urban agricultural practices, possibly contributing to improving soil cation exchange capacity (CTC).

A study conducted from June to September 2021 at the Faculty of Agriculture Experimental Garden, Respati University, Indonesia, investigated the potential of urban waste as a growing medium for microgreens (spinach and mustard greens). The research used a completely randomized design with four treatments: rockwool with AB Mix as a control, onion peels, rabbit manure, and quail manure, each replicated five times. Organic fertilizers from urban waste significantly affected the germination percentage, height, wet weight, and chlorophyll content of mustard green and spinach microgreens. While the rockwool control yielded the best chlorophyll content and microgreen production, among urban wastes, quail manure produced the highest chlorophyll content and production for mustard green microgreens. For spinach microgreens, onion peels resulted in the highest germination percentage and wet weight, while quail manure yielded the highest chlorophyll content.

2022Osmar Manoel Nunes, Shirley Grazieli da Silva Nascimento, Mariana Rockenbach de Ávila, Luciellen de Lourdes Silveira Vieira, Criziane Flores Pamplona · · Brazil
This preliminary study conducted a socioeconomic analysis of peri-urban family production of organic lettuce in Dom Pedrito-RS, Brazil, using case study techniques focusing on two family farmers. Through in-depth interviews and farm visits, it was found that production relied solely on family labor with minimal chemical inputs, characterizing a transition to organic production. Despite strong competition from large distribution networks, producing and marketing organic lettuce was concluded to be profitable, constituting an alternative income source and job creation in family farming, and assisting in transforming unoccupied spaces into productive ones.

2022José Hilario Rocha Araujo, A. Pando-Bahuon, C. Hartmann, H. Aroui-Boukbida, Thierry Desjardins, Thomas Z. Lerch · Frontiers in Ecology and Evolution · Global
This study evaluated the possibility of growing green vegetables on soils made from excavated deep horizon soils and green waste compost. Over three seasons, the effects of different amounts of compost (10, 20, and 30%) and the addition of earthworms (Lumbricus terrestris) on the production of lettuce, arugula, and spinach were tested in situ. The results demonstrated that it is possible to reuse urban mineral and organic wastes to engineer soils adapted to agriculture. Higher doses of compost significantly increased plant biomass, especially when earthworms were introduced.
CompostOrganic cycleEffect of Substrate Type and Fertilizing Management Programs on Yield and Nitrate Content of Both Molokhia and Spinach Grown on Rooftops in Egypt
2022· Middle East Journal of Agriculture Research · Egypt
Two experiments were conducted in 2020 and 2021 on a rooftop garden in Giza, Egypt, to investigate the effect of substrate type and fertilizing programs on molokhia and spinach yield and nitrate content. Substrate S1 (50% perlite: 50% peat moss) was found more suitable for high yield. While chemical nutrient solution (CNS) alone resulted in the highest yield, the combination of S1 and CNS followed by compost tea for 5 days before harvest (CNS+5) was most suitable for high yield with lower nitrate accumulation.

This study investigated the effects of agrivoltaic systems on rooftop microclimates and PV efficiency. ENVI-met simulations showed that PV temperatures in plots with crops below the PV system were 2.83 °C lower on sunny days and 0.71 °C lower on cloudy days, leading to a 1.13–1.42% and 0.28–0.35% improvement in PV efficiency, respectively. Data from a physical prototype indicated that evaporative cooling reduced ambient temperatures, with the agrivoltaic system generating 3.05–3.2% more energy daily compared to a control without crops.

This study in Dinoyo, Surabaya, Indonesia, investigated the potential of using 595,040 m3/year of canal sediment as a growing medium for urban farming. Sediment was mixed with green compost and cocopeat in 1:1:1, 1:3:1, and 1:5:1 ratios, and Capsicum frutescens seedlings were grown for two weeks. After pretreatment (drying, grinding, sieving), the 1:1:1 mixture showed optimal parameters: 3.58% C, 0.31% N, 0.02% P, 1.63% K, CEC 43.92 emol/kg, C/N 21, pH 8.55, non-toxic with 4% seed growth inhibition, optimal seedling growth, and lower nutrient loss. The research suggests that sediment can be used as a more environmentally friendly mixed growing substrate in the long term.

2022Petra Schneider, Tino Fauk · · Global
A study based on a literature review and field survey conducted from 2017 to 2020 in Ecuador, Germany, Sweden, Uganda, and Vietnam, examined the role of allotment gardens (AGs) in connecting nature and people. Allotment gardens provide substantial urban ecosystem services, contribute to habitat connectivity, and significantly impact human health. Beyond food production and recreation, they offer crucial benefits for public health, wellbeing, social inclusion, the environment, and serve as cultural archives, with their intrinsic purpose being connectivity for habitats, people, ecosystem services, and circular flux management.

This study evaluated a backyard system using 50cm × 50cm pinewood boxes for maize and peanut over nine months. Approximately 213 kg of organic residues were converted into 300 kg of mature compost, and plant development was compared between compost and control conditions. Correlation analyses of morphological properties showed that nutrient effects were positively associated with crop morphology, with maize yields of 9 kg/m2 in compost conditions and 6.6 kg/m2 in control, and peanut yields of 184 g/m2 in compost and 73 g/m2 in control.

The effectiveness of liquid organic fertilizer (POC) made from household vegetable waste on the growth and yield of microgreen spinach (Amaranthus tricolor) was investigated using a completely randomized design with four treatments and three replications. Various POC treatments (derived from spinach, potato, and water spinach) showed no significant difference in the growth and yield of microgreen spinach. The treatment without POC, using well water, showed optimal growth patterns and yields compared to the application of various POCs.
DIYCompostOrganic cycleThe combined application of nitrogen and biochar reduced microbial carbon limitation in irrigated soils of West African urban horticulture
2022Anne-Louise Fritz, Ramia Jannoura, René Beuschel, Christoph Steiner, Andreas Buerkert, Rainer Georg Joergensen · Chemical and Biological Technologies in Agriculture · Africa
This 2-year study in semi-arid Ouagadougou and sub-humid Tamale, West Africa, measured the effects of biochar and N fertilization on soil microbial biomass carbon, fungal ergosterol, and functional diversity. Sole biochar addition did not affect soil chemical or biological properties, but biochar with N fertilization increased microbial respiratory response. N fertilization decreased soil pH by 1.1 units in both cities, and a pH of 4.7 led to reduced microbial biomass carbon and ergosterol contents in Tamale. An N fertilizer-induced decline in soil pH below 5 should be avoided, as it decreased microbial biomass carbon and microbial functional diversity.

This research, conducted from October to December 2020 at Greenhouse CV. Kurnia Kitri Ayu in Indonesia, investigated the effect of 10 combinations of planting media (soil, roasted husk) and goat manure doses on lettuce growth and yield using a Randomized Block Design. The study found that combinations of planting media and goat manure supported lettuce growth more effectively than media without these additions. Specifically, treatment P7 (Soil and Roasted Husk 2:1 + 75g goat manure) yielded the highest average weight of 44.67g and economic weight of 40.67g.
