Re: [compost_tea] too much N

Fungi use the sawdust as an energy resource, but have to take N from the
soil in order to use the sawdust. So, N from the soil is immobilized in the
fungi, growing on the sawdust.
 
Typically the body of the fungus will be spread through the soil and
sawdust. How far away from the sawdust will the zone of N-tie-up extend? Depends
on the amount of sawdust, and the concentration of N in the soil around the
sawdust, but typically the zone of depletion extends several cm or an inch of
so.
 
If there is plenty of good soil around, then the roots won't be hurt. Poor
soil? Then there could be a problem!
 
Hope this helps!
 
Elaine.
