Fire transforms fuels (ie biomass, necromass, soil organic matter) into materials with different
chemical and physical properties. One of these materials is ash, which is the particulate …

Many physical, chemical, mineralogical, and biological soil properties can be affected by
forest fires. The effects are chiefly a result of burn severity, which consists of peak …

For the past 3.8 billion years, the geochemistry of the Earth's surface-its atmosphere, waters
and exposed crust-has been determined by the presence of biota. Photosynthetic organisms …

Contemporary soil science and conservation methods of effective forestry Forests and the
soils that serve as their foundation cover almost a third of the world's land area. Soils …

The overall effects of fire on ecosystems are complex, ranging from the reduction or
elimination of aboveground biomass to impacts on belowground physical, chemical and …

Physiological ecology of forest production was originally planned as a second edition to the
well-known book by the same name, published 25 years ago ( Landsberg 1986). The …

A comprehensive and quantitative evaluation of the effects of fire on ecosystem nitrogen (N)
is urgently needed for directing future fire research and management. This study used a …

Most forests in North America remain nitrogen limited, although recent studies have
identified forested areas that exhibit symptoms of N excess, analogous to overfertilization of …

Atmospheric phosphorus fertilizes plants and contributes to Earth's biogeochemical
phosphorus cycle. However, calculations of the global budget of atmospheric phosphorus …
