We produced four vegetable composts by using tomato biomass residues in an on-farm composting plant.
The tomato-based composts were assessed for their chemical, microbiological properties, and their effects on soils
and plants were evaluated after their application within a tomato cropping system. Compost characteristics affected
plant development and productivity through increased nutrient uptake and biostimulation functions. Soil biological
activities, including basal respiration, fluorescein diacetate hydrolysis, β-glucosidase, dehydrogenase, alkaline
phosphatase, arylsulphatase, and Biolog community levels of physiological profiles, were differently affected by the
on-farm tomato-based composts.
