| Abstract | The sustainable production of tomatoes (Solanum lycopersicum) is important, and this can be achieved by determining the rate of respiration of microbes in the tomato plants' rhizosphere soil. This study aimed at the potential of microbes to utilize carbon substrates embedded in the rhizosphere soil thereby contributing to the healthy nature of the tomato plants. The potential soil physiochemical features and utilization of carbon substrate by soil microorganisms as a result of their respiration to reveal their functions in the ecosystem were evaluated. The soil samples were amassed from the healthy tomato plant rhizosphere, diseased tomatoes, and bulk soil in this study. The physiochemical features and carbon substrate utilization in the bulk soil samples, and rhizosphere samples of powdery diseased, and healthy tomato plants were assessed. The MicroRespTM procedure was used to determine the community-level physiological profiles (CLPP) employing fifteen (15) carbon (C) substrates selected based on their importance to microbial communities embedded in the soil samples. Our results revealed that various physiochemical properties, moisture content, water retention, and C substrates including sugar, amino acid, and carboxylic acid were greater in HR and the substrates were not significantly different (p < 0.05). The study reveals higher soil respiration in HR as a result of the microbial communities inhabiting HR utilizing more of the C-substrates. This investigation contributes to the tomato plant's healthy state as the microbial communities utilized carbon substrate compared to DR after employing the CLPP assays.
