Bacterivorous Nematodes Drive Ammonification and Bacterial Community Growth in a Strongly Acidic Soil

Journal of Sustainable Agriculture and Environment, Journal Year: 2025, Volume and Issue: 4(1)

Published: March 1, 2025

ABSTRACT Nematodes, the most abundant animals on Earth, play a vital role in soil biosphere by regulating microbial communities and influencing nutrient cycling. However, their grazing impact nitrogen (N) cycling remains insufficiently understood. In this study, we addressed knowledge gap through microcosm experiment using gamma‐sterilised acidic (pH < 4.5), inoculated with either suspension alone or combination low high concentrations of nematodes. Our results revealed that nematodes significantly increased NH₄⁺–N content bacterial abundance, bacterivorous increasingly dominating environment. This study provides new evidence enhance ammonification soil, implications for N availability agricultural productivity.

Efficacy of poultry manure and biochar of cassava peels on root-gall nematode (Meloidogyne incognita) of okra (Abelmoschus esculentus) in an endemic Ultisol.

International Journal of Agricultural Technology, Journal Year: 2025, Volume and Issue: 21(2), P. 491 - 506

Published: March 23, 2025

In an endemic ultisol, the efficacy of poultry manure and biochar derived from cassava peels against root-gall nematode okra was investigated at Undergraduate Demonstrative Farms, Federal University Technology, Owerri, Imo State, Nigeria. With four replicates, field trial a 2x4 factorial in randomized complete block design. Two types okra, Maha Dizengoff were used treatments, along with three organic soil amendments: manure, made peels, poultry, control. The number leaves, height plant (cm), total pods, weight pod (g), shoot root index (0–4) data that taken. variety yielded significantly (P<0.05) higher (10.01 cm) (5.40 g) than (8.44 cm 5.19 g), respectively. findings additionally demonstrated exhibited quality terms (85.60 pods (16.50 which varied considerably variety's 12.06 75.00 g, Compared to all other amendments employed this study, growth yield parameters boosted plots treated mixture manure. best way lessen harm did apply This can be utilized as sustainable management technique (Meloidogyne incognita) soil.

Changes in soil organic carbon components and microbial community following spent mushroom substrate application

Frontiers in Microbiology, Journal Year: 2024, Volume and Issue: 15

Published: May 17, 2024

While spent mushroom substrate (SMS) has shown promise in increasing soil organic carbon (SOC) and improving quality, research on the interplay between SOC components microbial community following application of diverse SMS types remains scant. A laboratory incubation experiment was conducted with two SMSs from cultivation Pleurotus eryngii (PE) Agaricus bisporus (AB), each at three rates (3, 5.5, 8%). Advanced techniques, including solid-state 13C nuclear magnetic resonance (NMR) high-throughput sequencing, were employed to investigate fractions chemical structure, composition functionality. Compared SMS-AB, SMS-PE increased relative abundances carbohydrate O-alkyl C SOC. In addition, abundance bacterial phylum Proteobacteria those fungal phyla Basidiomycota Ascomycota. The cellulose-degrading (e.g., Flavisolibacter Agromyces) genera Myceliophthora, Thermomyces, Conocybe) as well. SMS-AB aromaticity index SOC, aromatic C, contents humic acid heavy fraction carbon. significantly Firmicutes Actinobacteria. Notably, Actinomadura, Ilumatobacter, Bacillus, which positively correlated acid, experienced an increase abundance. Functional prediction revealed that elevated metabolism reduced prevalence pathogens, particularly Fusarium. high-rate (8%) enhanced amino plant pathogenic fungi.
