Fire is common in savannas but its effects on soil are poorly understood. We analyzed long-term effects of fire on surface soil of an open Brazilian savanna (campo sujo) in plots submitted to different fire regimes during 18 years. The five fire regimes were: unburned, quadrennial fires in middle dry season, and biennial fires in early, middle or late dry season. Soil was collected during the wet and the middle dry season of 2008, and analyzed for pH, organic matter, total N, potential acidity… 

Effects of fire regimes on herbaceous biomass and nutrient dynamics in the Brazilian savanna

This study explores the long-term effects of fire treatments on biomass and nutrient pools in an open savanna from Central Brazil. Treatments included early, middle and late dry season burns every 2

Post-fire nutrient availability in the sub-tropical forest ecosystem of the Koubru Hills , Manipur

Forest fires are known to significantly alter soil nutrient availability. The study investigated the post-fire nutrient availability in the sub-tropical forest ecosystem of Koubru Hills, Manipur

Post-fire nutrient availability in the sub-tropical forest ecosystem of the Koubru Hills, Manipur

The study investigated the post-fire nutrient availability in the sub-tropical forest ecosystem of Koubru Hills, Manipur (North-East India) disturbed by forest wildfire in January 2010 and results are contradictory.

Effects of Recent Fire on Soil Conditions and Nutrient Use of a Native and an Invasive Grass in the Brazilian Savanna

ABSTRACT In fire-influenced savanna ecosystems, native and invasive exotic plants may use different abilities to coexist and compete for nutrients available in post-fire soil. The availability and


This research consists of a comparative study through the controlled application of fire under different conditions of natural and exotic phytophysiognomy of the Cerrado vegetation area. The area of

The effects of fire on soil properties have been widely studied in different ecosystems globally. However, only limited studies exist in the savanna tropics of Africa with mostly inconsistent

Geoderma Impact of fire and post-fire management techniques on soil chemical properties

The effects of fire (Control burned soil) and two emergency stabilisation techniques (grass Seeding and straw Mulching) on 20 chemical characteristics were evaluated on 0-5 cm top-soils sampled 1,

Short-term effects of early-season fire on herbaceous composition, dry matter production and soil fertility in Guinea savanna, Nigeria

Burning altered the growth (ground cover) and composition of plant species in the short term, and could significantly influence soil nutrient dynamics in the long term, especially with recurring fire events.



Soil–vegetation relationships in cerrados under different fire frequencies

Fire is an important ecological factor that structures savannas, such as the cerrado, by selecting plant species and altering soil nutrient content. In Emas National Park, central Brazil, we compared

Effects of high- and low-intensity fires on soil properties and plant growth in a Bolivian dry forest

We compared soil nutrient availability and soil physical properties among four treatments (high-intensity fire, low-intensity fire, plant removal, and harvesting gap) and a control (intact forest

Fires in Australia’s tropical savannas: Interactions with biodiversity, global warming, and exotic biota

The vast tropical savanna region of northern Australia is generally flat, vegetated by native species and sparsely populated by people. The climate is typified as monsoonal, with contrasting wet and


The soil water regimes of two areas of open savanna (campo sujo) near Brasilia, Brazil, were monitored between August 1999 and November 2000. Each area was subjected to a different fire regime. Soil

Seasonal variations in soil water in two woodland savannas of central Brazil with different fire history.

Soil water uptake patterns were strongly seasonal, and despite similarities in hydrological processes, the protected area systematically used more water than the burned area, indicating a strong coupling of atmospheric water demand and the physiological response of the vegetation.

Soil and air temperatures during prescribed cerated fires in Central Brazil

ABSTRACT Air and soil temperatures were measured during dry season heading fires in three different physiognomic forms of native vegetation common in Central Brazil: cerrado sensu stricto (dense

Effects of fire on properties of forest soils: a review

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.

The effect of fire on soil properties

Fire affects nutrient cycling and the physical, chemical, and biological properties of soils occupied by westernmontane forests. Combustion of litter and soil organic matter (OM) increases the

Fire behaviour a key factor in the fire ecology of African grasslands and savannas.

The effect of fire on natural ecosystems involves the response of living organisms to the release of heat energy through the combustion of plant material. The manner in which and the factors that

Fires in the cerrado, the Brazilian savanna

The cerrado is the largest area savanna formation in South America, and originally covered approximately 25% of the Brazilian territory. The savanna forms of cerrado are characterized by a ground
