Agro-Based Spent Mushroom Compost Substrates Improve Soil Properties and Microbial Diversity in Greenhouse Tomatoes

Spent mushroom compost (SMC) substrates are commonly used as growth media for greenhouse crops and horticulture production. This study aimed to investigate the responses of physiochemical soil properties, enzyme activities, microbial community compositions different cultivation durations SMC treatments on tomatoes. The experiment included following treatments: substrate surrounding after planting at 1, 3, 7 years comparing control including non-planting continuous mono-cropping soil. results revealed that had higher contents total N P organic C nutrients than treatments. physicochemical properties activities were significantly decreased with longer duration. Microbial alpha diversity was in regardless duration It observed many beneficial microbes, such bacteria Deinococcus-Thermus, Halanaerobiaeota, Nitrospirae phyla, fungi Basidiomycota, Mortierellomycota, Chytridiomycota phyla enriched substrates. several potentially microorganism genera bacterial Saccharimonadales, Gaiella, Bacillus, fungal Thermomyces, Kernia, Mortierella. Therefore, agro-based grooved system is recommended an environmentally compatible practice tomato greenhouse.
