TLDR
This work is a review of the up-to-date literature dealing with changes imposed by fires on properties of forest soils, and ecological implications of these changes are described.Abstract:
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 temperatures and duration of the fire. Climate, vegetation, and topography of the burnt area control the resilience of the soil system; some fire-induced changes can even be permanent. Low to moderate severity fires, such as most of those prescribed in forest management, promote renovation of the dominant vegetation through elimination of undesired species and transient increase of pH and available nutrients. No irreversible ecosystem change occurs, but the enhancement of hydrophobicity can render the soil less able to soak up water and more prone to erosion. Severe fires, such as wildfires, generally have several negative effects on soil. They cause significant removal of organic matter, deterioration of both structure and porosity, considerable loss of nutrients through volatilisation, ash entrapment in smoke columns, leaching and erosion, and marked alteration of both quantity and specific composition of microbial and soil-dwelling invertebrate communities. However, despite common perceptions, if plants succeed in promptly recolonising the burnt area, the pre-fire level of most properties can be recovered and even enhanced. This work is a review of the up-to-date literature dealing with changes imposed by fires on properties of forest soils. Ecological implications of these changes are described.read more

TL;DR: For base year 2010, anthropogenic activities created ~210 (190 to 230) TgN of reactive nitrogen Nr from N2 as discussed by the authors, which is at least 2 times larger than the rate of natural terrestrial creation of ~58 Tg N (50 to 100 Tg nr yr−1) (Table 6.9, Section 1a).

Wildfire as a hydrological and geomorphological agent
TL;DR: In this paper, a review summarizes current knowledge and identifies research gaps focusing particularly on the contribution of research from the Mediterranean Basin, Australia and South Africa over the last two decades or so to the state of knowledge mostly built on research carried out in the USA.

Reappraisal of drying and wetting effects on C and N mineralization and fluxes in soils.
Werner Borken,Egbert Matzner +1 more
TL;DR: In this paper, the authors evaluated the impact of drying and wetting on the mineralization and fluxes of C and N in terrestrial soils and found that despite wetting pulses, cumulative mineralization is mostly smaller compared with soil with optimum moisture, indicating that dry soil cannot compensate for small mineralization rates during drought periods.

Recent development in the treatment of oily sludge from petroleum industry: A review
TL;DR: The origin, characteristics, and environmental impacts of oily sludge were introduced and no single specific process can be considered as a panacea since each method is associated with different advantages and limitations.

Ecology and Management of Forest Soils

TL;DR: In this article, the authors discuss the physical, chemical, and biological aspects of forest soils, with additional discussion on soil organic matter, roots, and biogeochemistry, highlighting the site specific factors that are important in each case and discusses practical management aspects including: nutrition management, thinning, site preparation techniques, soils for nursery and seed orchard operation, problem soils, atmospheric deposition of nutrients, soil acidity, and techniques for sustaining and improving long term soil productivity.
