“…Soil nematode, however, are critical to soil and general ecosystem function as they prey upon these soil microbes and thereby cycling soil nutrients (Osler & Sommerkorn, 2007 ; Semeraro et al, 2022 ). Soil nematode could prevent or cause plant diseases (Wu et al, 2021 ) and are key predators preying other soil micro‐fauna (Kostenko et al, 2015 ; Peguero et al, 2019 ). Neglecting prescribed fire effects on soil nematodes prevents a full picture of the belowground effects of fire on ecosystem structure and functioning (Gomez et al, 2022 ; Zaitsev et al, 2016 ).…”

Fire is a common disturbance in many biomes, with both beneficial and detrimental effects on soil biology, which largely depend on fire intensity. However, little is known about the impact of fire on soil nematode communities in terrestrial ecosystem. In the present study, we investigated the effects of short‐term prescribed fire on soil nematode communities and soil properties in an old‐field grassland in Northern China. The results showed that burning significantly increased soil nematode abundance by 77% and genus richness by 49% compared to the control. Burning also decreased taxon dominance by 45% (Simpson's D ) and increased nematode diversity by 31% (Shannon‐Weaver H '). However, burning increased plant parasites (particularly genera Cephalenchus and Pratylenchus ) and shifted community to more bacterial‐feeding genera (i.e., decreased Channel Index). Generally, burning increased soil bio‐available nitrogen (NH 4 + –N and NO 3 − –N) content, which would be the main drivers causing nematode community to flourish via a “bottom‐up” effect. These results suggest that prescribed fire increases nematode diversity and alters community composition toward more plant parasites and bacterial feeders. Our findings highlight the importance of prescribed fire management in shaping short‐term nematode community structure and function, but the long‐term effects and impacts of these changes on soil nutrient and carbon cycling remain unknown.

“…There have been numerous reports on the effect of continuous planting on soil microbial ecosystems, with studies focusing on herbal medicines, agricultural crops, vegetable ( Li et al., 2021a ; Pang et al., 2021 ; Wu et al., 2021 ). However, there is still less information on the effects on soil microorganisms after continuous planting of artificial timber trees, especially C. equisetifolia ( Liu et al., 2020 ; Li et al., 2021b ; Xu et al., 2021 ; Ma et al., 2023 ).…”

Continuous planting has a severe impact on the growth of Casuarina equisetifolia. In this study, the effects of three different long-term monocultures (one, two and three replanting) on the physicochemical indexes, microbial functional diversity, and soil metabolomics were analyzed in C. equisetifolia rhizosphere soil. The results showed that rhizosphere soil organic matter content, cation exchange capacity, total and available nitrogen, total and available phosphorus, and total and available potassium contents significantly decreased with the increasing number of continuous plantings. The evaluation of microbial functional diversity revealed a reduction in the number of soil microorganisms that rely on carbohydrates for carbon sources and an increase in soil microorganisms that used phenolic acid, carboxylic acid, fatty acid, and amines as carbon sources. Soil metabolomics analysis showed a significant decrease in soil carbohydrate content and a significant accumulation of autotoxic acid, amine, and lipid in the C. equisetifolia rhizosphere soil. Consequently, the growth of C. equisetifolia could hinder total nutrient content and their availability. Thus, valuable insights for managing the cultivation of C. equisetifolia and soil remediation were provided.

“…in soils, which significantly reduces the carbon cycling capacity of the soil, decreases soil fertility, and increases the incidence of root disease, leading to a significant reduction in ginseng yield and quality ( Liu et al., 2022 ). It can be seen that the key reason for the effect of continuous planting on plant growth is caused by changes in soil texture due to changes in soil microbial ecosystems ( Pang et al., 2021b ; Wu et al., 2021 ).…”

Casuarina equisetifolia (C. equisetifolia) is an economically important forest tree species, often cultivated in continuous monoculture as a coastal protection forest. Continuous planting has gradually affected growth and severely restricted the sustainable development of the C. equisetifolia industry. In this study, we analyzed the effects of continuous planting on C. equisetifolia growth and explored the rhizosphere soil microecological mechanism from a metagenomic perspective. The results showed that continuous planting resulted in dwarfing, shorter root length, and reduced C. equisetifolia seedling root system. Metagenomics analysis showed that 10 key characteristic microorganisms, mainly Actinoallomurus, Actinomadura, and Mycobacterium, were responsible for continuously planted C. equisetifolia trees. Quantitative analysis showed that the number of microorganisms in these three genera decreased significantly with the increase of continuous planting. Gene function analysis showed that continuous planting led to the weakening of the environmental information processing-signal transduction ability of soil characteristic microorganisms, and the decrease of C. equisetifolia trees against stress. Reduced capacity for metabolism, genetic information processing-replication and repair resulted in reduced microbial propagation and reduced microbial quantity in the rhizosphere soil of C. equisetifolia trees. Secondly, amino acid metabolism, carbohydrate metabolism, glycan biosynthesis and metabolism, lipid metabolism, metabolism of cofactors and vitamins were all significantly reduced, resulting in a decrease in the ability of the soil to synthesize and metabolize carbon and nitrogen. These reduced capacities further led to reduced soil microbial quantity, microbial carbon and nitrogen, microbial respiration intensity, reduced soil enzyme nutrient cycling and resistance-related enzyme activities, a significant reduction in available nutrient content of rhizosphere soils, a reduction in the ion exchange capacity, and an impediment to C. equisetifolia growth. This study provides an important basis for the management of continuously planted C. equisetifolia plantations.
