Mineralization and distribution of nutrients in plants …
Webmineralization by reducing microbial demand for N (i.e., microbial immobilization) during decomposition [10, 13]. However, grazing can also reduce N turnover and availability, as grazers feed selectively on plants with high N content and thus increase the dominance of plant species with low N content, and litter from those species ... WebIn an uncut old forest, mineralizable-N in buried bags was highest among sites in early summer, but extremely low in early fall. Clearcut sites sustained relatively high N-mineralization rates throughout the growing season, with the highest rate occurring on the 4-year-old site and lower rates occurring in the older clearcuts.
