Urban agriculture is crucial for enhancing food security in densely populated areas, but maintaining soil health these settings key long-term productivity. This study investigates the effects of locally produced compost and biochar amendments on plant nutrients at two urban farms Sacramento, California, USA. Regionally sourced was from pistachio shells, made on-site green waste, creating a closed-loop system that recycles organic materials back into soils. We hypothesized combined application would increase water holding capacity nutrient retention, leading to enhanced microbial activity higher concentrations corn compared individual amendments. Field trials were established both sites using randomized complete block design with four treatments: control, applied approximately 25 t ha −1 (equivalent 10 Mg C ), 12.5 compost-biochar mix (20 ). Soil samples collected during mid- late-season, analyzed physicochemical properties. Corn kernel also measured. Over one growing season, results showed treatments significantly increased capacity, matter content, cation exchange better structure retention. nitrate (NO 3 − –N) bioavailable phosphorus (P) biochar-amended The metabolic community evenness, though overall diversity remained stable. kernels exhibited concentrations, particularly P, Mg, Ca, Fe. Overall, combination treatment had most significant impact improving properties, responses, demonstrating their cumulative benefits crop nutrition. By utilizing recycling this demonstrates resource-efficient approach fertility resource-limited farms. These practices have potential play vital role addressing challenges communities, those experiencing insecurity, while promoting sustainable resource management.

Animal manure is considered a valuable organic fertilizer due to its important nutrient content enhancing soil fertility and plant growth in agriculture. Besides beneficial role as fertilizer, animal represents significant source of volatile compounds (VOCs), playing atmospheric chemistry. Understanding the composition VOCs from crucial for assessing their environmental impact, they can cause air pollution, odors, harm human health ecosystems. Laboratory studies enhance field measurements by providing precise inventory emissions, addressing gaps existing literature. Both approaches complement each other advancing our understanding emissions. In this context, we conducted an experimental study involving various manures (cow, horse, sheep, goat) taken farm Grignon (near Paris, France). We employed simulation chambers within controlled laboratory environment. The analysis involved combination Proton Transfer Reaction-Quadrupole ion guide-Time-of-Flight Mass Spectrometry (PTR-QiTOF-MS) Thermal Desorption-Gas Chromatography-Mass (TD-GC-MS). Using PTR-QiTOF-MS, 368 were detected quantified samples. complementary TD-GC-MS enhanced identification VOCs. Our findings revealed chemical groups VOCs, including oxygenated (e.g., ethanol, cresol, acetaldehyde, etc.), nitrogenated (ammonia, trimethylamine, sulfur (methanethiol, dimethyl sulfide, aromatic (phenols indoles), terpenes (isoprene, D-limonene, etc.) halogenated compounds. Cow exhibited highest VOC emission fluxes, followed goat, horse manures. Notably, dominant contributors total fluxes all Statistical highlighted distinct nature cow characterized addition, goat was isolated samples with high emissions having both oxygen nitrogen atoms molecular formulas CH

Abstract Composting is a basic solution to recycle organic waste and reduce its detrimental impact on public health the environment. However, possibility of offensive odors emerging during breakdown process one difficulties with composting. Researchers have created several methods for controlling composting odor. Some these are traditional that infrequently used, while other advanced especially those innovated in last decade very efficient reducing Biofiltration most effective methods. In this review paper, odor will be covered concentrating biofiltration method.

California's organic waste diversion law, SB 1383, mandates a 75% reduction in organics disposal by 2025 to reduce landfill methane emissions. Composting will likely be the primary alternative landfilling, and 75-100 new large-scale composting facilities must sited state meet its goal. We developed strategy for evaluating site suitability commercial incorporating land-use, economic, environmental justice criteria. In our Baseline scenario, we identified 899 candidate sites, nearly all are within cost-effective hauling distance of cropland rangelands compost application. About half mostly rural areas, not collection enough municipal supply an average-sized facility. Conversely, sites near cities have greater access but cause health damages from ammonia volatile compounds emitted during process. The additional required capacity corresponds $266-355 million annual air pollution. However, this excludes avoided emissions could reduced 56% if aerated static piles used instead windrows. Siting higher number smaller decentralized also help equally distribute pollution avoid concentrating burdens certain communities.
