The Impacts of the C/N Ratio on Hydrogen Sulfide Emission and Microbial Community Characteristics during Chicken Manure Composting with Wheat Straw

Agriculture, Journal Year: 2024, Volume and Issue: 14(6), P. 948 - 948

Published: June 18, 2024

Wheat straw (WS) has long been subjected to rough treatment by traditional incineration, which not only results in the waste of biomass resources but also poses a risk atmospheric pollution and is conducive sustainable utilization natural resources. With great humification potential, WS can be utilized as valuable composting material. The study optimized C/N ratio mixing chicken manure (CM) raw materials, found that this method could significantly improve compost quality. In comparison conventional poplar woodchip (PW) conditioning, incorporation resulted an elevated temperature, extended high-temperature period, more expeditious lignocellulose degradation, notable enhancement organic matter content, suppression hydrogen sulfide production under low ratio, promotion elemental sulfur conversion, collectively contributing enhanced overall quality environmental friendliness compost. Correlation analysis microbial communities factors demonstrated mixed facilitated growth actinomycetes sulfur-transforming bacteria. Additionally, structural equation model indicated parameters such temperature pH value played key role process.

Climate change and global warming pose serious threats to agriculture, water resources, the environment, especially in Mediterranean climate zone. This region is facing rising temperatures decreasing rainfall, while frequency of extreme weather events, such as droughts, floods, heavy increasing. The basin holds only 1.2% world’s renewable it expected that freshwater resources will decrease by 25–50% 2050. Turkey one most affected countries, with diminishing sources significant losses agricultural land, creating challenges for both supply rural development. Rising have negatively impacted traditional farming practices. For example, planting dates winter crops like wheat barley shifted, resulting lower yields due stress. Moreover, shortages led reduced soil moisture, making harder grow during critical periods. In Turkey, much used agriculture comes from groundwater, which rapidly depleting, causing a decline groundwater levels increased energy costs extraction. To overcome these challenges, sustainable management practices must be implemented. Efficient irrigation techniques, water-saving methods, solutions enhance productivity are crucial addressing issues.

Biochar Characteristics and Application: Effects on Soil Ecosystem Services and Nutrient Dynamics for Enhanced Crop Yields

Nitrogen, Journal Year: 2025, Volume and Issue: 6(2), P. 31 - 31

Published: April 27, 2025

Although intensive farming practices have greatly increased food production, they undermined the soil ecosystem services on which agriculture depends. Biochar application in soils is increasingly gaining worldwide acceptance as a means of addressing these environmental challenges while enhancing agricultural productivity. offers dual benefits that support security and ecological well-being through enhanced fertility plant nutrition. These include water retention, promotion microbial functioning, carbon sequestration, nutrient absorption, among others. In spite known benefits, many studies continue to emphasize roles biochar plays health crop yields but often neglect influence characteristics, are key optimizing services. Thus, it important understand how characteristics supporting, regulating, provisioning This review comprehensive integrative assessment biochar’s rather than examining each service individually. The focus feedstock material pyrolysis temperature determine generated efficacy supplying dynamics for yields.

ACS Sustainable Resource Management, Journal Year: 2024, Volume and Issue: 1(3), P. 563 - 576

Published: March 14, 2024

Food waste contributes to environmental degradation by emitting greenhouse gases and depleting natural resources, but it also exacerbates global hunger poverty. This study investigated the use of food digestate (FWD) as fertilizer on ornamental plant (Piper sarmentosum) cultivation under soil amendment growing media such organic compost (OC), biochar, rice husk (RH) in a 56-day trial. A significant increase growth was observed potting mix with amendments combined application FWD comparison without application. In OC, found higher chlorophyll content index 1.48%. this followed 2.76% 1.29% than RH. Furthermore, number leaves leaf areas plants increased significantly (>2%) added OC The identified microbial phyla were Acidobacteriota, Actinobacteriota, Bacteroidota, Firmicutes, Proteobacteria, Verrucomicrobiota, some have closed networking, like Firmicutes Proteobacteria.

Techno-Economic Assessment of Anaerobic Digestion Technology for Small- and Medium-Sized Animal Husbandry Enterprises

Published: May 8, 2024

Investments in small and medium-sized anaerobic digestion facilities have the potential to boost biogas production Greece other EU countries. This study aimed evaluate economic feasibility of equipped with combined heat power (CHP) units ranging from 50 400 kW, while treating livestock waste. For this purpose, data were gathered various operations (dairy cattle, poultry, swine, dairy sheep goat) regarding their annual production, revenues, electricity fuel usage, waste generation. Waste samples then collected analyzed assess biochemical methane potential. The capital operational costs facilities, calculated using equations developed within “eMT cluster” project. Findings indicate that current feed-in tariffs (FIT) 0.21 € kWh-1 are insufficient incentivize investment capacities below 250 highlighting need for increased FIT rates or expenditure subsidies. Recommendations include shifting towards simplified technology business models reduced farmer involvement, coupled supportive legislative framework long-term price guarantees. These measures expected foster implementation projects animal husbandry sector.

This study aimed investigate the effects of digestate derived from pilot-scale livestock waste-recycling system, in combination with low copper concentration fungicide, on physiological response lettuce cv Rufus (Lactuca sativa L.) plants associated soil microbiome. A five-week microcosm experiment was conducted greenhouse under conditions. Lettuce plant performance assessed terms biomass, leaf area index, photosynthetic activity, chlorophyll measurements, lipid peroxidation, total phenolic content, nutrient uptake. The results suggested that incorporating into potting mix significantly enhanced crop yields compared control treatments. microbial activity increased presence fertilizers, improving biological properties. addition negatively affected growth both manure-treated conditions, except for those grown digestate, where accumulation reduced. These findings highlight potential growing horticultural crops using organic fertilization through anaerobic establishing waste-to-food recycling system.
