Amount of leaf litter

Clean

Dirty

Area (±0.05m)

5.00m×5.00m(25m²)

2.50m×2.50m(6.25m²)

Amount of leaf litter collected (24hours) (±1.0g)

519.9g

2.15g

Amount of leaf litter in that would fall in one year in each soil

Clean

Dirty

Amount if leaf litter in one year (in 25m²)

8976.3g/yr

779g/yr

Calculation

Amount of leaf litter in one year = amount of leaf litter collected in 24hours×365

Clean: 519.9×365=18976.3g/yr Dirty: 12.5×4×365=1779g/yr

The amount of water passes through the 25g of clean and dirty soil in 5minutes
