    Introduction: Soil microorganisms play a crucial role in ecosystem functioning, nutrient recycling, and plant health. This study investigates the abundance of fungi and bacteria in the soil of three different gardens: pine, cassava, and eucalyptus garden. Soil samples were collected from each garden and microbial abundance was assessed using plate counts. The abundance of soil microorganisms is critical to maintaining soil heath, influencing nutrient cycling, organic matter decomposition, and plant productivity (Smith and Paul, 2020). This study aims to assess the abundance of soil microorganisms in different garden; that is to say pine garden, eucalyptus garden, and cassava garden. The findings suggest that gardens with greater plant diversity and organic amendments have a significantly higher microbial count (Brown and Thompson, 2021). METHODS: Three gardens in Busitema University Nagongera Campus were selected and soil samples were picked from them and taken to the biology laboratory for further investigation on the abundance of microorganisms like fungi and bacteria in each garden. The methodology undertaken was plate count technique and staining technique. The plate count technique is a widely utilized method for estimating the abundance of viable microorganisms in soil samples. This method is particularly useful in quantifying bacteria and fungi, which play essential roles in soil health and fertility. RESULTS: The results show significant differences in microbial abundance between the gardens, with the cassava garden having the highest bacteria abundance, followed by the pines garden with the higher bacterial abundance and lastly the eucalyptus garden with the least bacterial abundance. The pine garden with the highest fungal abundance, followed by the cassava garden with higher fungal abundance and lastly with eucalyptus garden with the least fungal abundance. CONCLUSION: From the study it was observed that cassava garden having the highest abundance of bacteria while pine garden having the highest fungal abundance that could be influenced by various factors, including soil composition, moisture levels, temperature, PH levels, and the presence of organic material.
