Influence of organic matter management on the activity and structure of soil microbial community in intensive tomato (Solanum lycopersicum L.) greenhouse farming

Aim of study: Intensive agriculture impacts physical, chemical, and biological characteristics soil; therefore, the addition organic matter (OM) to soil can have significant implications for crop production. This study investigated impact three management systems on tomato production microbial communities in intensive greenhouse farming.
 Area Province Almería (Spain).
 Material methods: The included: (1) conventional management, using synthetic chemical fertilizers without OM application (CM); (2) with at least one last years (CMOM); (3) fully featuring yearly applications no use (ORG).
 Main results: Compared CM soils, CMOM ORG led higher NO3- NH4+ content, which turn increased nitrogen (N) availability, leading an increase respiration. also altered composition prokaryotic fungal communities. Besides, reduced presence abundance potential pathogenic organisms, like Sclerotinia sp. Plectosphaerella cucumerina. conventionally managed greenhouses (CMOM) yields compared greenhouses, resulting overall 880 g m-2. Production under (ORG) was lowest, possibly due nutrient pest practices used.
 Research highlights: Our data show importance shaping systems, be a key factor developing more sustainable feed growing human population.
