“…Last, controlled burning can lead to a significant reduction in microbial biomass C (Pietikäinen and Fritze, 1995). This decline in microbial biomass C after controlled burning has either a direct effect or indirect effect on decreasing the soil moisture content, destroying soil structure or increasing soil pH (Fritze et al, 1994). However, in our study, microbial biomass C did not change with the controlled burning compare to the brush clearing.…”

“…During the burning, the burning intensity determines the amount of ash (Certini, 2005), soil properties (Boerner et al, 2000), soil microbial and root mortality (Chapin et al, 2004). In addition, ash deposition can increase the soil respiration (R S ) through increased nutrient release and hence available C substrate for microbes (Fritze et al, 1994), whereas alterations in soil chemistry can reduce microbial activity (Pietikäinen and Fritze, 1995;Badía and Martí, 2003). However, the relative importance of each of these components of burning on R S is largely unknown.…”

a b s t r a c tSite preparation, as an important procedure before afforestation, can affect soil C release. However, the effect of site preparation on soil C release has not been sufficiently investigated. Two site clearing treatments (brush clearing and controlled burning) followed by three soil preparation treatments (overall soil preparation, spot soil preparation, and no soil preparation (control)) were carried out in subtropical China. Soil basal respiration (R S ) and C release of biomass burning were measured as soil C release on an area basis from March 2011 to March 2013. The site preparations changed the soil C release in the first year but had no effects in the second year. Compared with brush clearing (control), controlled burning (control) significantly increased the annual soil C release (decreased R S but increased C release of biomass burning) during the first year. Within the brush clearing plots, overall soil preparation significantly increased the R S rate over eight months and resulted in an increase in annual soil C release during the first year compared to the no soil preparation. In contrast, spot soil preparation increased the R S rate only for three months and did not affect the annual soil C release during the first year relative to the no soil preparation. In the controlled burning plots, both overall and spot soil preparation increased the R S rate across six months, but only overall soil preparation caused a significant increase in the annual soil C release. Our study suggests that minimizing the disturbance of the site preparation would decrease soil C release. Concluding, the spot soil preparation followed brush clearing is a good choice for site preparation in term of soil C storage.

The effects of wood ash fertilization on soil chemical properties were studied in three young Scots pine (Pinus sylvestris L.) plantations and a Norway spruce (Picea abies (L.) Karst.) plantation with different site fertility in southern Finland. The dose of 3 t ha -1 of loose wood ash was applied to 4 replicate plots (25 × 25 m) at each experiment. Humus layer and mineral soil samples were taken before the treatment and 7 and 16 years after wood ash application. Results showed that neutralization as well as fertilization effects of wood ash on forest soil were of long duration. An ash-induced pH increase of 0.6-1.0 pH units and exchangeable acidity (EA) decrease of 58-83% were detected in the humus layer 16 years after wood ash application. The decrease in acidity was most pronounced on the Calluna site with initially the lowest pH and highest EA. In the mineral soil the increase in pH was observed later than in the humus layer. After 16 years, the mineral soil pH was increased (0.2-0.3 pH units) on the Vaccinium and Myrtillus sites. A corresponding and in most cases a signifi cant increase in the extractable Ca and Mg concentrations was detected in both the humus layer and in the mineral soil. Wood ash signifi cantly increased the effective cation exchange capacity (CEC e ) and base saturation (BS) but decreased the concentration of exchangeable Al in both soil layers on all the sites. No response of N availability to wood ash application could be found.

“…However, the soil in the 100 Mg ha-1 plot was considered to have the lowest ability to supply mineral N among the soils in the rainy season. Burning of 10 to 20 Mg ha-1 biomass corresponding to the values recorded in Karen peoples' shifting cultivation system was more compatible with soil ecology in terms of N supply at the initial stage of crop growth and of microbial biomass recovery during the rainy season, compared to the burning of 100 Mg ha-forest management (Fenn et al 1993;Fritze et al 1994) or pasture management (Singh et al 1991). However, in the case of shifting cultivation for daily subsistence, the effects have not been thoroughly studied, for example, in India (Ramakrishnan 1992) and in Thailand (Tulaphitak et al 1985a, b).…”
