Seasonal changes in inorganic and organic phosphorus in the soil of a riparian forest

Impacts of grassland afforestation with coniferous trees on soil phosphorus dynamics and associated microbial processes: A review

“…This was coupled with increases in soil total organic C, N and P under the grassland, which was probably due to increased organic inputs from root litter (Perrott et al, 1990;Tate et al, 1991;Chen et al, 2000). But under the adjacent forest, soil total organic C, N and P contents were relatively constant over the seasons, and a sharp increase in NaHCO 3 extractable organic P in winter might be related to leaching of dissolved organic matter (and P) from the forest floor (Fabre et al, 1996). Based on the results from this study, a hypothetical seasonal P recycling model in soils under grassland and adjacent forest is proposed (Fig.…”

Seasonal changes in soil phosphorus dynamics and root mass along a flooded tropical forest gradient in the lower Orinoco river, Venezuela

“…Comparisons of our results with other studies are difficult, because to our knowledge no one has analyzed the effects of flooding on the soil P distribution and availability in seasonal flooded forests of tropical regions. Data from a riparian forest in a temperate zone showed seasonal variations in soil P fractions (Fabre et al 1996). The authors found that the most labile P forms (resin-Pi, NaHCO 3 -Pi, NaOH-Pi and NaHCO 3 -Po) were highly dependent on seasons with accumulation during winter and decrease during the spring.…”

“…The effect of experimentally controlled variation of soil redox potential on P mobility has been shown in several studies (Willet and Higgins 1978;Phillips and Greenway 1998;Mello and Torrent 1998;McLatchey and Reddy 1998;Mitchell and Baldwin 1998;Young and Ross 2001;Wright et al 2001;Turner and Haygarth 2001;Corstanje and Reddy 2004;Chacón et al 2006a, b). However, substantially less research has been directed towards the understanding of how natural flooding and subsequent draining of soils change the soil P distribution and availability, especially in floodplain forests (Fabre et al 1996;Darke and Walbridge 2000).…”

Changes in soil P chemistry as affected by conversion of natural secondary forests to larch plantations

“…However, there also appear inconsistent findings (e.g. Tate et al, 1991;Magid and Nielsen, 1992;Fabre et al, 1996). For instance, the maximum values of soil bicarbonate-extractable inorganic P and bicarbonate-extractable organic P have been found to occur in summer (Zhao et al, 2009) or winter (Fabre et al, 1996), or there lacks significant seasonal variation in soil resin-extractable inorganic P (Tate et al, 1991).…”
