Summary Some intensive agricultural practices result in soil degradation through loss of organic matter. Organic farming may mitigate this problem, if managed properly, but a yield penalty compared with conventional systems. Biochar addition to could influence both systems, previous studies are not definitive about its impact on processes. Sandy soils more susceptible the effects reduced matter hydrology and nutrient dynamics. Nitrogen (N) is important for crop growth water content can...
Peat is used as a high quality substrate for growing media in horticulture. However, unsustainable peat extraction damages peatland ecosystems, which disappeared to large extent Central and South Europe. Furthermore, disturbed peatlands are becoming source of greenhouse gases due drainage excavation. This study the result workshop within EU COST Action TD1107 (Biochar option sustainable resource management), held Tartu (Estonia) 2015. The view stakeholders were consulted on new biochar-based...
Biochar produced by pyrolysis of organic residues is increasingly used for soil amendment and many other applications. However, analytical methods its physical chemical characterization are yet far from being specifically adapted, optimized, standardized. Therefore, COST Action TD1107 conducted an interlaboratory comparison in which 22 laboratories 12 countries analyzed three different types biochar 38 physical–chemical parameters (macro- microelements, heavy metals, polycyclic aromatic...
Organomineral fertilisers (OMFs) were produced by coating biosolids granules with urea and potash. Two OMF formulations N : P 2 O 5 K compositions: 10 4 (OMF ) 15 developed for application in grassland arable crops. Routine fertiliser analyses conducted on four batches of compared a sample to determine key physical chemical properties the materials which affect handling spreading, soil behaviour, value. Bulk particle densities range 608 618 kg m −3 , 1297 1357 respectively. Compression tests...
Livestock production is important for food security, nutrition, and landscape maintenance, but it associated with several environmental impacts. To assess the risk benefits arising from livestock production, transparent robust indicators are required, such as those offered by life cycle assessment. A central question in approaches how burden allocated to products manure that re-used agricultural production. incentivize sustainable use of manure, should be considered a co-product long not...
Land degradation and inadequate faecal sludge management are two major issues in Sub-Saharan Africa (SSA). The transformation of human excreta into soil amendments their wide-scale adoption could improve health contribute to solving the sanitation crisis SSA. There however perception challenges around these fertilisers because potentially harmful components they contain such as pathogens heavy metals, which can be removed with appropriate treatment composting. A barrier wide scale...
Abstract Amorphous silica, a specialised silicate adsorbent is extensively extracted from agricultural residues for application in various environmental domains. Wheat straws are rich source of silica that have earlier been overlooked however demand value addition. The study presents an innovative approach to extracting wheat straw and standardising the extraction process produce clean product. sodium solution amorphous synthesis were obtained by modifying template mediated sol–gel method....
This paper presents a facile and effective method for the large-scale production of carbon dots (CDs) from diverse coconut wastes (fronds, husk shell). On comparing two different methods, namely (i) hydrothermal carbonization (ii) novel sequential synthesis processes (pyrolysis followed by sonication), latter procedure recorded higher recovery CDs (14.0%) over (2.33%). Doping agents such as urea, polyethyleneimine (PEI) hexamethylenetetramine (HMTA) were chosen at varying concentrations to...
Core Ideas Agronomic efficiency of organomineral fertilizers higher than biosolids granules. Organomineral reduces the risk soil P build‐up compared with biosolids. Conversion sewage sludge into improves fertilizer value Field‐scale experiments in four crop seasons established agronomic performance biosolids‐derived (OMF) for winter wheat ( Triticum aestivum L.) production England. Two OMF formulations (OMF 10 10:4:4 and 15 15:4:4) were urea granules (≈5:6:0.2) to determine responses effects...
A circular economy relies on demonstrating the quality and environmental safety of wastes that are recovered reused as products. Policy-level risk assessments, using generalised exposure scenarios, informed by stakeholder communities have been used to appraise acceptability necessary changes legislation, allowing be valued, marketed. Through an extensive assessment exercise, summarised in this paper, we explore burden proof required offer assurance consumer brand-sensitive food sectors light...
Efficient fecal sludge management solutions are especially challenging in densely populated urban informal settlements, where space is limited and land tenure uncertain. One solution to collect treat human excreta produce soil conditioners for use agriculture, through container-based sanitation, thus realizing the circular economy sanitation. This study focused on sanitation ventures that sell fertilizers from excreta. Stakeholder interviews showed challenges faced by these were similar:...
The antimicrobial substance triclosan has widespread use in personal care products and can enter the terrestrial environment if sewage sludge is applied to soil. inhibitory effects of on basal substrate-induced respiration (SIR) three different soils were investigated. Soils dosed later redosed with four nominal concentrations, rates measured over time. In each soil, a significant depression was noted after initial dosing, followed by recovery. extent inhibition positively related dose,...
