The fundamental ecosystem processes in soil are regulated by microbial communities, and community diversity is implicated by soil environmental conditions. Humic acid (HA) improves soil quality and fertility, stimulating the microbial environment, but the detailed effects remain poorly understood. We investigated the effects of HA rates on soil bacterial diversity, particularly on species richness and community composition in the rhizosphere of corn (Zea mays). Inorganic fertilizer (T2), HA 0.5% (T3), HA 1.0% (T4), HA 1.5% (T5), and HA 2.0% (T6) were applied in soil. Initial soil (O1) and control after harvesting (T1) were included. A total of 3601 operational taxonomic units were captured from the overall sample, and analysis of 16S ribosomal ribonucleic acid amplicon sequencing data indicated that HA did not notably impact species richness. Intriguingly, HA induced changes in bacterial community composition, along with the relative prevalence of specific taxa. Certain associations between soil chemical properties and abundance distribution have been uncovered. Notably, exchangeable Mg2+, Ca2+, and available phosphorus were strongly related to the relative abundance of bacterial phyla. Furthermore, HA potentially shaped the specific bacterial taxa, as the application of HA at different rates had distinct effects on the member of bacterial abundance of each taxon. These findings enhance our understanding of communities potentially being increased or shifted by HA rate addition in short‐term corn cultivation.

Lei bamboo (Phyllostachys violascensʻPrevernalisʼ) is a high economic value species with high yield and good quality of bamboo shoots. However, heavy chemical fertilizer and covering cultivation are used to produce off-season bamboo shoots, resulting in soil degradation and a decline in soil productivity. This study introduced an amino acid fertilizer called fish protein fertilizer to replace part of chemical fertilizer, and investigated the effect of different fertilizer combinations on bamboo growth, shoot yield and soil properties to clarify the growth-promoting mechanism of amino acid fertilizer. Results showed that after replacing 45 kg of compound fertilizer with 10 kg or 20 kg of fish protein fertilizer (1) bamboo shoot yield increased by 23.24% or 26.19%, respectively; (2) growth of leaves and roots were enhanced, thick root proportion increased, and proportion of root in the topsoil layer decreased; (3) soil pH, contents of AP (available phosphate), SOC (soil organic carbon), MBC (microbial biomass carbon) and MBN (microbial biomass nitrogen), soil enzyme activity increased; (4) contents of N and P in leaf increased, while the N/P and K/P decreased. Overall, amino acid fertilizer can promote microbial growth and improve soil enzyme activity through supplying carbon sources and nitrogen sources, thus promoting phosphorus activation and increasing soil phosphorus effectiveness, and then improving the foraging scale of root systems, and ultimately enhancing nutrients absorption and increasing bamboo shoot yield.
