Large oak stems were more common in dry sites [ILLUSTRATION FOR FIGURE 2 OMITTED] where mineralizable
N was greatest [ILLUSTRATION FOR FIGURE 3 OMITTED].
C and N were estimated as the C[O.sub.2] and extractable N[H.sub.4] + N[O.sub.3] produced in a 10-d room-temperature incubation of unamended soil at field moisture content.

The increase in SMBC might be due to the supply of additional mineralizable
and readily hydrolyzable carbon due to organic manure application resulted in higher microbial activity and in turn higher microbial biomass carbon.
Soil N supply both initial levels which can now be quantified quickly and cost effectively (Schmidhalter2005) and mineralizable
soil N are important components in optimising N fertilizer application (Olfs et al.
This was in agreement with Tu et al.'s  early study which concluded that straw mulching further enhanced available N content by 30% over 2 years, and they also noticed a 182~285% increase in potential mineralizable
