A soil scientist applies three treatments to a 240 m² test plot, each covering 1/3 of the area. After treatment, microbial activity increases by 20% in Treatment A, 35% in Treatment B, and 50% in Treatment C. If initial activity values were 100, 80, and 60 units respectively per section, what is the total post-treatment microbial activity across all treatments?

Soil Microbial Activity Boosts After Targeted Soil Treatments Soil scientists play a critical role in understanding how various treatments impact microbial communities — key indicators of soil health. A recent study applied precision treatments to a 240 m² test plot divided into three equal sections of 80 m² each, known as Treatment A, B, and C. By enhancing microbial activity across these sections, researchers aim to improve soil fertility and ecosystem resilience. Initial Microbial Activity Levels
Before treatment, the microbial activity per section was measured as follows:
- Treatment A: 100 units
- Treatment B: 80 units
- Treatment C: 60 units After targeted interventions, each plot experienced distinct percentage increases in microbial activity:
- Treatment A saw a 20% increase
- Treatment B recorded a 35% increase
- Treatment C achieved a 50% increase
