The application of organic fertilizers and biological inputs to soil inevitably affects its quality, agrochemical indicators, and microbiota. Sustainable agriculture is based on continuously learning about how to properly manage available soil, water, and biological resources. The aim of the study was to determine changes in microorganism communities and carbon stocks in infertile soils for fertilization using different organic fertilizers and their combinations with bio-inputs. Genetic analysis of microorganism populations was performed using the NGS approach. Our study showed that the application of organic fertilizers affects the soil microbiota and the taxonomic structure of its communities. Specific groups of bacteria, such as , were promoted by organic fertilization, meanwhile the abundance of and decreased in most treatments after the application of poultry manure. Metagenomic analysis confirmed that the use of bio-inputs increased the relative abundance of spp. fungi; meanwhile, a significant change was not found in the representatives of compared to the treatments where the bio-inputs were not used. The positive influence of fertilization appeared on all the studied agrochemical indicators. Higher concentrations of C and N accumulated in the soil when we used granulated poultry manure, and pH when we used cattle manure.
向土壤中施用有机肥料和生物投入物不可避免地会影响土壤质量、农业化学指标和微生物群。可持续农业基于持续了解如何妥善管理现有的土壤、水和生物资源。本研究的目的是确定使用不同有机肥料及其与生物投入物的组合对贫瘠土壤施肥后微生物群落和碳储量的变化。使用NGS方法对微生物种群进行遗传分析。我们的研究表明，有机肥料的施用会影响土壤微生物群及其群落的分类结构。特定的细菌群体，如 ，通过有机施肥得到促进，同时在施用家禽粪便后的大多数处理中， 和 的丰度下降。宏基因组分析证实，使用生物投入物增加了 属真菌的相对丰度；同时，与未使用生物投入物的处理相比， 在其代表中未发现显著变化。施肥对所有研究的农业化学指标都产生了积极影响。当我们使用颗粒状家禽粪便时，土壤中积累了更高浓度的碳和氮，而当我们使用牛粪时，土壤pH值升高。
