This paper finds uniqueness in deriving 10 maturity parameters, 6 stability parameters with one parameter as confirmatory test of compost toxicity. It was concluded from the study that the Water Soluble Carbon (WSC) and Organic Nitrogen (Org. N) ratio is the key regulator of maturity parameter and the dehydrogenase (DHA) activity is important factor for compost stability.]]> Wed 31 Mar 2021 09:47:16 AEDT ]]> Soil enzymes and microbial elemental stoichiometry as bio-indicators of soil quality in diverse cropping systems and nutrient management practices of Indian Vertisols https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:42372 Wed 28 Feb 2024 14:52:25 AEDT ]]> Mineralisation of 14C-phenanthrene in PAH-diesel contaminated soil: Impact of Sorghum bicolor and Medicago sativa mono- or mixed culture https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47423 Thu 19 Jan 2023 13:03:30 AEDT ]]> Contamination of long-term manure-fertilized Indian paddy soils with veterinary antibiotics: Impact on bacterial communities and antibiotics resistance genes https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51982 Mon 25 Sep 2023 13:54:41 AEST ]]> Long-term application of manure over plant residues mitigates acidification, builds soil organic carbon and shifts prokaryotic diversity in acidic Ultisols https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:37363 2000 μm) from 7.8% in the control to 30.6% while it reduced effective diffusion coefficient of oxygen (DC₀) from 12.58 × 10⁻⁶ m² s⁻¹ in the control to 2.81 × 10⁻⁶ m² s⁻¹. Application of pig manure increased prokaryotic diversity and altered prokaryotic community structure, while crop residues did not. Soil pH was the predominant factor influencing prokaryotic community structure. Bacillales and Clostridiales accounted for 47.5% and 21.4%, respectively of the indicator species in the IPM and the relative abundances of them were increased, compared with the other treatments. Furthermore, the relative abundances of Bacillales and Clostridiales were correlated with SOC, TN, AP and DOC, and negatively with DC₀ in the soil. Overall, our results suggest that application of NPK fertilizer plus pig manure rather than crop residues enhanced soil pH, improved SOC content and aggregation, increased prokaryotic diversity and altered community structure of prokaryote after 27-year fertilization.]]> Mon 19 Oct 2020 10:43:20 AEDT ]]> Ecotoxicity of measured concentrations of soil-applied diesel: effects on earthworm survival, dehydrogenase, urease and nitrification activities https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:33332 Fri 03 Dec 2021 10:34:32 AEDT ]]>
