对有机肥料（家禽粪便）处理的表土和根际土壤进行了微生物分析。每隔三天（第1天、第4天、第7天和第10天）分析土壤样品。用家禽粪便处理的根际土壤的细菌总数（RS:P）最高，在2.1×106和5.7×106 CFU/g之间。用家禽粪便处理的表层土壤的细菌总数在1.9×106和4.9×106 CFU/g之间。对照组（未处理的根际土壤）的细菌总数在2.6×106和4.0×106 CFU/g之间，未处理的表层土壤的细菌数在1.4×106和2.4×106 CFU/g之间。用家禽粪便处理的表土真菌总数在0.2×106和0.9×106 CFU/g之间。用家禽粪便处理的根际土壤真菌总数在0.2×106和0.3×106 CFU/g之间。未处理的表层土壤的真菌总数在0.1×106和0.2×106 CFU/g之间，而未处理的根际土壤的真菌总量在0.1×106-0.2×106 CFU/g之间。根据其出现频率确定的细菌分离物为芽孢杆菌（16.8）、肠球菌（8.4）、梭菌（4.0）、葡萄球菌（8.0）、假单胞菌（15.6）、李斯特菌（12.0）、微球菌（14.0）、沙雷菌（4.8）和链球菌（7.2）。真菌分离物的发生率为根际菌属（26.7%）、青霉属（22.5%）、曲霉属（21.1%）、毛霉属（19.7%）和枝孢菌属（9.8%）。根系分泌的代谢物作为化学信号吸引大量微生物。在土壤中施用有机肥增加了土壤中的微生物数量，因此有必要在土壤中施有机肥，以促进农业可持续发展。
