Use fertilizer Forest Conservation

A replicated, randomized, controlled study in 2005-2004 in temperate coniferous forest in Washington State, USA (7) found that fertilizing after wildfire increased plant cover. Plant cover was higher in plots with low (34-40%) and high (38-45%) input of fertilizer than in unfertilized plots (28-31%). Data were collected in 2005-2006 in 24 plots (4 × 10 m) of each treatment: unfertilized, low fertilizer input and high fertilizer input (0, 56, 112 kg N/ha respectively) in each of eight sites. All sites were burned by wildfire in 2004 and were seeded with different seed mixtures.
