Improper waste management and increasing environmental pollution from contaminated water gaseous emissions are important challenges associated with rapid industrialization the growing population. These issues pose threats to climatic change, agricultural ecosystems, human health, environment. Vermicomposting offers a sustainable solution for recycling organic waste, nitrous oxide (N2O) being crucial greenhouse gas emitted during preparation application of vermicompost, contributing nitrogen (N) loss. However, extent N2O under different conditions remains uncertain. This study aims review literature evaluate relationship between two phases vermicomposting various substrate properties, including substance type, C: N ratios, pH, soil moisture content. The purpose this is significance vermicompost in reduction loads within processes vermicomposting. can also be utilized together conventional composting process enhance nutrient cycling rate mitigate ammonia emissions. findings showed that were higher phase, as compared phase In addition, dependent on ratio substrates, which turn influences nitrification denitrification processes. earthworms facilitate removal via mechanisms occurring their digestive tracts, denitrification. Overall, an eco-friendly technology lessen loads, particularly NH3 its preparatory phases, i.e. providing optimal substrates required plant growth ensuring health.

The massive loss of nitrogen (N) and phosphorus (P) from farmland ditches contributes to non-point source pollution, posing a significant global environmental challenge. Effectively removing these nutrients remains difficult in intensive agricultural systems. To address this, novel composite ecological ditch system (CEDS) was developed by modifying traditional drainage integrate grit chamber, zeolite, floating beds. Dynamic monitoring N P levels water, plants, zeolite conducted evaluate the system’s nutrient interception performance mechanisms. results showed following: (1) Water quality improved markedly after passing through CEDS, with concentrations decreasing progressively along flow path. intercepted 41.0% 31.9% P, inorganic particulate as primary forms loss. (2) Zeolite removes primarily ion exchange, likely chemical reactions, maximum capacities 3.47 g/kg for 1.83 P. (3) Ecological beds hydroponic cultivation enhanced uptake roots Canna indica Iris pseudacorus, surpassing (4) Nutrient efficiency positively correlated temperature, inlet concentrations, rice runoff but negatively precipitation. This study demonstrates CEDS’s potential improving water suggests further enhancements design management increase its economic aesthetic value.

Agribusiness ranks second as the sector with highest greenhouse gas emissions linked to methane, constituting a crucial challenge for global sustainability. Although its impact on climate change is considerable, small rural farmers do not have effective technologies manage organic waste derived from their daily activities. In this context, anaerobic digestion an innovative solution that converts into biogas and biofertilizers, promoting sustainable circular approach. However, implementation faces significant barriers due inadequate designs poor operational practices, which makes adoption difficult in areas. This applied theoretical research seeks overcome these by improving design operation of small-scale plants. The system studied operates at 70% capacity, hydraulic retention time 20 days feed 4 kg matter. substrates considered were 30% bovine manure, achieving average production 63.75 L CH4/kg matter, exceeded usual yields biodigesters. A mathematical model was created case study R2 correlation 98% pseudo-R2 89.5%, evidencing remarkable predictive capacity. plant efficient sustainable, it presented viable farmers.

Mining soil is considered a serious source of metal contamination worldwide due to its translocation and accumulation in various plant parts, causing severe impacts on growth. Results indicated that biochar manure improved barley root morphology compared contaminated soil. Moreover, Pb Cu were highly translocated shoots. Regarding treatments, 10% 20% increased the roots, while animal 2.5% Using 10%, 20%, promoted Zn roots (bioaccumulation factor: BAFroot≥1). According Dickson quality index tolerance index, plants showed high for metals Biochar effective reducing negative effects such as Cd plants. helps increase Our findings provide insight into potential enhance crop production under stress, leading assurance food supply sustainable agriculture stressful conditions.

Introduction Brewers' spent grain (BSG) is the most important by-product of breweries. Currently, primary method recycling BSG through its use in livestock feed production, due to high fiber content, non-degradable protein, and water-soluble vitamins. Nonetheless, composting, vermicomposting, biochar production pathways offer promising alternatives for managing this organic byproduct. Methods BSG-based substrates were evaluated as bio-fertilizers during transplantation Lactuca sativa L. without additional fertilization at end crop cycle. Biochar (B), vermicompost (V), compost (CP), enriched with a microbial consortium (CPE), each mixed 2 4% peat, compared two control treatments: 100% peat (C1) ternary chemical fertilizer (C2). The experiment was designed six replicates, half which inoculated Sclerotinia sclerotiorum mycelium assess contribution different pathogen resistance. Results Overall, it found that treatment C2 effective, yielding greatest plant height seedbed stage best results across all parameters harvest.
