Post-fire mulching for runoff and erosion mitigation Part II: Effectiveness in reducing runoff and sediment yields from small catchments

The immediate effectiveness of barley straw mulch in reducing soil erodibility and surface runoff generation in Mediterranean vineyards

“…Therefore, there is a need to find a balance between the cost and the efficiency of the straw mulch cover. In this regard, there are other researchers who studied the efficiency of mulches on fire affected land and found that the mulch cover of mulches does not need to be high to be efficient (Fernández et al, 2012;Prats et al, 2014;Robichaud et al, 2013a;2013b). In these cases, straw mulch was confirmed to have a positive effect on water quality (Faucette et al, 2007) and the mitigation of wind-induced soil erosion (Nelson, 2002).…”

Post-fire soil erosion mitigation: a review of the last research and techniques developed in Portugal

“…The relation between wildfire and soil erosion, however, is far to be straightforward. Various authors have measured extreme soil losses still eight years after the wildfire (Robichaud et al, 2013b) and others have reported negligible soil erosion rates after wildfires (Kutiel and Inbar, 1993;Sheridan et al, 2007), which indicated that soil type, soil parent material or vegetation re-establishment can be also important factors. In general, in Mediterranean regions including Portugal, post-fire soil erosion rates tend to be low (Fig.…”

Effects of post-fire soil stabilisation techniques on trace elements lost by erosion

“…Range of estimated concentration (mg kg 21 DW) and accumulated mass (g ha 21 ) of trace elements in eroded sediments of the present study compared with reference levels (mg kg 21 DW) A Estrada values estimated considering that 5% of total soil nutrient was removed by DTPA and EDTA extractants (Chen et al 1996;Fernández-Calviño et al 2012); DEC, European Union limit for concentrations of heavy metals in soil receiving sewage sludge application (CEC 1986) study (Díaz-Raviña et al 2012), the reduction of erosion rates with straw mulching (73-94%) was twice that with herbaceous seeding (34-42%) during the first 4 months after application. However, mulch effectiveness depends on strand length, ground cover amount, thickness of application and longevity (Bautista et al 1996;Wagenbrenner et al 2006;Groen and Woods 2008;Robichaud et al 2010;Fernández et al 2011;Robichaud et al 2013aRobichaud et al , 2013b.…”
