A soil scientist applies a fertilizer that increases daily microbial activity by 15% each day, compounding daily. If baseline activity is 80 units, what is the total microbial activity over the first 5 days, assuming daily compounding?

Title: How Daily Compounding Fertilization Boosts Microbial Activity: A 5-Day Scientific Breakdown When a soil scientist applies a fertilizer that increases microbial activity by 15% each day—compounding daily—understanding the long-term impact on soil health requires careful mathematical modeling. With baseline microbial activity starting at 80 microbial units, this compounding growth leads to exponential daily increases. But what does this mean in real terms? How much total microbial activity accumulates over the first five days? ### The Science Behind Daily Compounding Growth Unlike linear growth, daily compounding reflects microbial activity increasing on itself each day—just as a fertilizer boosts activity by 15% multiplicatively, not just additively. This means each day’s measurement builds on the previous day’s level, creating a compounding effect.
