Use fertilizer after tree planting
A replicated, controlled, before-and-after study in 2002-2007 in maritime pine Pinus pinaster forest in Portugal (Pires & Xavier 2010) found that fertilizing increased the size of planted maritime pine trees after cutting and chipping but not after cutting and removal of understory vegetation. After cutting and chipping, growth of maritime pines was greater in fertilized plots compared to unfertilized plots (fertilized: 48 m3/ha; unfertilized: 32 m3/ha). After cutting and removal, growth of maritime pine was similar between treatments (fertilized: 31; unfertilized: 25 m3/ha). Maritime pine trees were measured in July 2002 (immediately after cutting and removal/chipping) and in 2007 in three replicates of fertilized (20 g nitrogen/tree in September 2002) and unfertilized treatments (~800 m2) in cut and removed (all plants except maritime pine clearcut and removed) and three in cut and chipped plots (all plants clearcut and chipped). Maritime pine trees were planted in 1996 at 1,333 trees/ha.
