Objective: The objective of this study was to review natural ecosystems and agroecosystems to compare the abundance of soil microbial communities and also plant growth.
Material and Methods: This study used a random block design method, each soil from both ecosystems is planted with corn and string beans. Each treatment is repeated three times and arranged in random block design. At the end of the study, head height, root display and leaf count were calculated. The data obtained were then analyzed using the SAS 9.0 program. Results: The results showed that soils from agroecosystems had greater microbial abundance and good plant growth responses.
Conclusion: The results showed that agroecosystems are ecosystems that have an abundance of microbial communities that are the most good compared to forest ecosystems. This has an impact on good growth responses in agroecosystems compared to forest ecosystems.
