Incorporating straw into the soil is a sustainable practice that can mitigate some of adverse effects excessive N fertilization on structure degradation and microbial diversity reduction. This objective this study was to determine combined management (straw return removal) (0, 360, 450, 540, 630, 720 kg ha-1 yr.-1) crop yields, properties, communities in long-term wheat-maize cropping system. The results showed moderate application (N450-N540) with optimized wheat (283.5 ha-1) maize (346.5 whereas higher (N630, N720) led acidification (pH decline 0.51-1.67 units), irrespective management. Straw increased organic carbon (SOC), total nitrogen (TN), nitrate (NO3 --N), available potassium (AK), but decreased ammonium (NH4 +-N). Bacterial at rates rates. Fungal generally under removal, Chaetomiaceae increasing return, Mortierellaceae Trichocomaceae declined high levels. Mantel test strong correlation between pH bacterial diversity, while fungal composition influenced by SOC, TN, NO3 --N. Partial Least Squares Path Modeling (PLS-PM) demonstrated directly indirectly yield through improved enhanced supported yield. highlights importance balanced incorporation maintaining community structure, fertility, productivity intensive systems Vertisol.

Nitrogen Enrichment Alters Plant Root, Soil Microbial Structure, Diversity, and Function in Mountain Forests of North China

Forests, Год журнала: 2025, Номер 16(3), С. 459 - 459

Опубликована: Март 5, 2025

Nitrogen (N) enrichment significantly impacts temperate forest ecosystems, but we lack a comprehensive understanding of the responses root morphological characteristics, soil microbial communities, and multifunctionality concurrently to varying degrees N enrichment, particularly when exceeding threefold localized input in forests. Therefore, selected four communities China’s forests experimented with addition dominant tree species each community through bag method (three treatments were set up: N1, fourfold total N; N2, sixfold CK, control). The results showed that (1) improved modified leading increases RD (root diameter) RTD tissue density) decreases SRL (specific length) SRA area). (2) also substantially changed composition functional taxa. relative abundance eutrophic bacteria increased, while oligotrophic saprotrophic fungi decreased. (3) α-diversity index decreased, co-occurrence networks became less complex more vulnerable under treatments. (4) Soil alpha diversity had substantial negative correlation. (5) NH4+-N NO3−-N contents key factors affecting dominance phyla, as well bacterial Shannon fungal Chao1 index. (6) In addition, properties (except NO3−-N), enzyme activities, different among species. summary, alters characteristics improves multifunctionality. Concurrently, it reduced α-diversity, increased bacteria, decreased saprophytic fungi, community. This study provided important data insights for repertoire nitrogen ecosystems.

Nutrient Availability Shapes the Resistance of Soil Bacterial Community and Functions to Disturbances in Desert Ecosystem

Environmental Microbiology, Год журнала: 2025, Номер 27(3)

Опубликована: Март 1, 2025

ABSTRACT Climate change has exposed desert ecosystems to frequent extreme disturbances, including wet‐dry cycles and freeze–thaw events, which accelerate desertification on a global scale. The limited nutrient availability characteristic of these may constrain microbial survival growth, making them more vulnerable environmental perturbations stressors. However, how modulates the stability soil ecological communities functions in remains poorly understood. In this study, we examined addition, applied either before or after affects resistance bacterial multifunctionality drought freeze events ecosystems. Our findings revealed that rather than drought, significantly reduced diversity, with all disturbances altering community structure. Pre‐disturbance addition notably improved diversity composition played critical role maintaining This enhanced was strongly associated increased network complexity enrichment disturbance‐tolerant taxa. results highlight pivotal stabilising under climatic conditions These offer valuable insights practical strategies for protection management desertification.
