Urea Fertilizer

	Urea Fertilizer:
	I am presently looking for the effect of applying UREA fertilizer to a 
plantation of 1+0 black spruce ( or any other related spieces ).  The relavent 
information that would be appreciated is 
	1) The effect on volume yield (i.e. after 5 yrs, 10yrs and so on )
	2) THe amount of fertilizer that should be applied per hectare and means of 
application.
	3) The effect on the plants if 650 kg/ha is applied; would this be a lethal 
amount on a sandy soil type.
	

	Any imformation or response would be much appreciated
	
	Thanks.
