Dead leaves now linger longer in Veluwe forests as acidic soils suppress decay‎

Decomposition of dead leaves in Veluwe forests has declined by tens of percent since the turn of the century. Meteorologists from Wageningen University & Research discovered this in an analysis of long-term measurements. The cause appears to lie in soil acidity. This is noteworthy because nitrogen deposition in the area has actually decreased over the same period. The effects of nitrogen entering the ecosystem in the past may still be lingering.
