ABSTRACT Phosphorus (P) fertilization and straw incorporation are essential agricultural practices, both of which have an influence on the abundance diversity indigenous arbuscular mycorrhizal fungal (AMF) community. However, there still research gaps interactive effects P fertilizer application AMF in coastal saline–alkali land. Thus, this study aimed to assess several features, abundance, community composition soil a field after 4‐year barley–cotton rotation. We also explored roles play enhancing cotton uptake. The was treated with five triple superphosphate levels (0, 22, 44, 66, 88 kg ha −1 ) subjected either or removal. total content increased increasing rates; however, percentage partitioned bolls, boll capacity root system (BCR), loading (BLR) exhibited trend initially followed by decrease. highest value achieved when combined 44 . Besides, colonization AMF, spore density were at 22 without treatment. Redundancy analysis (RDA) revealed that observed shift primarily driven enhancement rhizosphere pH organic matter following incorporation. Overall, these findings showed coupled moderate created favorable environment, which, turn, enhanced thereby improving production facilitating distribution reproductive organs. Our results suggested threshold input can provide basis for saving effectively maintain ecosystems'

Long-term fertilization altered microbial community structure in an aeolian sandy soil in northeast China

Frontiers in Microbiology, Journal Year: 2022, Volume and Issue: 13

Published: Sept. 7, 2022

Soil microorganisms play crucial roles in nutrient cycling and determining soil quality fertility; thus, they are important for agricultural production. However, the impacts of long-term fertilization on microbial community remain ambiguous due to inconsistent results from different studies. The objective this study was characterize changes bacterial fungal diversity structures after 12 years aeolian sandy by analyzing 16S rRNA ITS gene sequences properties discover driving factors. Eight fertilizer treatments have been set up since 2009: no (CK), chemical N (N), P (NP), N, K (NPK), pig manure only (M), plus (MN), (MNP), P, (MNPK). indicated that application reduced pH, whereas addition alleviated a decrease pH value. Chemical significantly improved available nutrients organic carbon. Long-term MNPK resulted effects specific species; contrast, all properties. Principal component analysis had significant effect structure, combined with greater than alone. phosphorus, total were most factors influenced taxa, carbon, ammonium nitrogen nitrate influencing taxa soil.

Straw interlayer improves sunflower root growth: Evidence from moisture and salt migration and the microbial community in saline-alkali soil

Journal of Integrative Agriculture, Journal Year: 2024, Volume and Issue: 23(11), P. 3870 - 3881

A straw interlayer added to soil can effectively reduce salinity effects on plant growth, however, the of moisture, salt and microbial community composition growth under a are unclear. rhizobox study was conducted investigate role thickness migration, composition, as well root in sunflower. The included four treatments: Control (no interlayer); S3 (straw 3.0 cm); S5 5.0 S7 7.0 cm). Straw treatments increased moisture by 8.2%-11.0% after irrigation decreased content bud stage 0-40 cm soil. Total length, total surface area, average diameter, volume number tips sunflower plants were higher than control, highest treatment. This stimulated ascribed abundance Chloroflexi Verrucomicrobia bacteria with interlayer, which 55.7 54.7%, respectively, Addition 5 is practical environmentally feasible approach for improving saline-alkali
