 movement in a South Carolina pine forest. Ecol. 

 55:1120-1127. 



Rainwater, runoff, groundwater and leachate 

 derived from litter had greater quantities of 

 nutrients after burning. Nitrate and phosphate 

 did not increase in leachate until some time 

 later, suggesting biological release processes. 

 Cations, however, were highly susceptible to 

 various means of translocation.

 status of herbacious communities of the Derbyshire

Retention of soluble nutrients in soil at 

 intervals after fire was studied in blocks of soil 

 in the laboratory. Potassium leached from soil 

 after plant ash addition, but P and Ca did not. A 

 short-term increase in P and in one case, N, in 

 plant tissues occurred during the first season 

 after fire. Effects from fire on the soils 

 studied were not great.

 raking and burning under red and white pine. Soil 

 Sci. Soc. Am. Proc. 15:381-390. 



Comparison of mechanical litter removal and 

 removal by burning showed that pH increase from 

 liming was similar to pH increase by burning. 

 Total N and organic C increased in mineral soil 

 over check in all treatments, but was highest on 

 the burned treatment. Available P in the All 

 horizon of burned plots increased markedly over 

 other treatments. Liming of burned areas 

 increased the effect even more. Effects on volume 

 of wood and height growth were shown.

 changes following a forest wildfire in northern 

 Minnesota: effects in watersheds with differing 

 soils. Oikos 28:105-112. 



Nutrient input to nearby lakes was monitored for 

 3 years following a spring wildfire. Input 

 differed due to soil type but was unaffected by 

 the fire. Authors felt that revegetation retained 

 fire-released nutrients in the forest.
