What can occur if a mound system is not adequately aerated?

When a mound system is not adequately aerated, it can lead to slower breakdown of organic material. Aeration is essential for the microbial processes that decompose organic matter in the soil. Proper aeration provides the necessary oxygen for aerobic microorganisms, which play a crucial role in breaking down waste. Without sufficient oxygen, these microorganisms become less active, leading to a buildup of organic matter and slower decomposition rates. This can result in reduced overall efficiency of the mound system, as the organic materials may not be processed effectively, potentially leading to system failure or reduced absorption capabilities over time. The other options describe processes that are generally supported by adequate aeration rather than hindered by a lack of it.
