“…In the present study, the NaOH-Po content was the dominant organic P fraction. The high content of NaOH-Po in the larch plantation was consistent with previous research in Pinus radiata forest soil (Liu et al 2004). Interestingly, the larch plantation in this study depleted the NaOH-Po fraction, but other organic P fractions were unaffected by N addition, suggesting that the NaOH-Po pool is important in providing plant-available P through mineralization.…”

Abstract• The key message N addition decreased soil inorganic P availability, microbial biomass P, and acid phosphatase activity in the larch plantation. Soil inorganic P availability decreased after N addition due to the changes in both microbial properties and plant uptake.• Context Soil phosphorus (P) availability is considered an important factor in influencing the biomass production of plants. Sustained inputs of nitrogen (N) through atmospheric deposition or N fertilizers, particularly in temperate forests, may change the composition and availability of P and thus affect long-term forest productivity.• Aims The objective of this study was to assess soil P availability, P fractions, and microbial properties including microbial biomass P and acid phosphatase activity after 9 consecutive years of N addition in a larch (Larix gmelinii) plantation, northeastern China.• Methods From 2003 to 2011, NH 4 NO 3 was added to replicate plots (three 20 m×30 m plots) in the larch plantation each year at a rate of 100 kg N ha. Soil samples from 0-10-cm and 10-20-cm depths were collected in N addition plots and control (no N addition) plots.• Results N addition significantly decreased soil NaHCO 3 -Pi (Pi is inorganic P), microbial biomass P, and acid phosphatase activity but increased the NaOH-Pi concentration. N addition appeared to induce a decrease in soil inorganic P availability by changing pH and P uptake by trees. In addition, N addition significantly decreased the NaOH-Po (Po is organic P) concentration, possibly because of increased P mineralization. However, the total P and other P fractions were unaffected by N fertilization.• Conclusion Our results suggested that N addition enhanced P uptake by trees, whereas it reduced soil inorganic P availability as well as microbial biomass and activity related to soil P cycling in the larch plantation.Keywords Larch plantation .

“…They proposed the use of a sequential extraction Bray-2 P test to predict soil P availability to the trees. Another reason for the failure of the soil P test to predict P response is that the trees were taking up P from the rhizosphere soils where the ectomycorrhizae help the roots to take up more P (Liu et al 2004) than that indicated by the soil P test conducted on bulk soils away from the rhizosphere.…”

Changes in phosphorus (P) fractions and their plant-availability and downward movement in two strongly P fixing acidic Andosols (Allophanic and Pumice Soils) under Pinus radiata plantations in New Zealand were studied 2 years after triple superphosphate (TSP) and a phosphate rock (BGPR, origin Ben Guerir, Morocco) application, each at four rates, to determine the fate and plant availability of fertilizer-derived P in these soils. The rate of increase of the concentrations of the P fractions was highest for NaOH-P i (inorganic P associated with Fe and Al oxides and allophane) when TSP was applied and highest for H 2 SO 4 -P i (predominantly calcium phosphates or apatite-type P minerals) when BGPR was applied. The largest pool of soil P, the NaOH-P o (labile organic P), was unaffected by the P fertilizer applications. The rate of NaOH-P i concentration increase was higher in the higher P fixing Allophanic Soil than in the Pumice Soil. Both types of fertilizers increased resin-P i (Inorganic P freely available to the plant) and Bray-2 P concentrations but only the TSP application increased Olsen P concentration. Phosphorus derived from TSP and BGPR applications moved down to 10-20 cm soil depth within 2 years of application in the Pumice Soil, but did not move below 10 cm depth in the higher P fixing and less porous Allophanic Soil. The fertilizers significantly increased needle P concentrations 2, 3 and 4 years after fertilizer application, but did not have any significant effect on tree growth.

Apart from following C fluxes, this versatile method can be used to characterize the spatial distribution and its change over time of added radioactive P (Hendriks et al 1981;Hübel and Beck 1993;Lindahl et al 2001), SO 4 2− (Jungk and Claassen 1997) or Zn and Cd (Whiting et al 2000).…”
