Replication Data for: “Phosphorus sorption and availability in an andosol after a decade of organic or mineral fertilizer applications: importance of pH and organic carbon modifications in soil as compared to phosphorus accumulation"

Dataset of the paper entitled Phosphorus sorption and availability in an andosol after a decade of organic or mineral fertilizer applications: importance of pH and organic carbon modifications in soil as compared to phosphorus accumulation. We conducted a 10-years-old field experiment on an andosol and compared fields that had been amended with mineral or organic (dairy slurry and manure compost) fertilizers against a non-fertilized control. Water and Olsen extractions and inorganic phosphorus sorption experiments were realized on soils sampled after 6 and 10 years of trial. We also realized an artificial and ex situ alkalization of the control soil to isolate the effect of pH on the sorption capacity of inorganic phosphorus.

论文《有机或矿物肥料施用十年后火山灰土（Andosol）中磷的吸附与有效性：与磷积累相比，土壤pH值及有机碳变化的重要性》对应的数据集。我们在火山灰土（Andosol）上开展了一项为期10年的田间试验，将施用矿物肥料或有机肥料（奶牛粪浆与粪肥堆肥）的地块与未施肥对照地块进行对比。在试验进行6年和10年后采集土壤样本，开展了水提取、Olsen提取及无机磷吸附试验。我们还对对照土壤进行了人工异位碱化（ex situ）处理，以分离pH值对无机磷吸附能力的影响。
