摘要在新西兰Manawatu的10个农林基地，将辐射松下的表层矿质土壤的某些性质与邻近牧场下的土壤进行了比较。在过去的10年里，没有一个地点接受过石灰。总体而言，辐射草原土壤样品的pH值较低，而铝的提取态浓度较高。辐射松的交换性钙值较低，为96-1275公斤/公顷。树木吸收和森林地面发展可以解释高达550公斤/公顷，在六个站点的差异小于550公斤/公顷，这表明钙一般是由辐射松生态系统保存。土壤交换性钠和镁值通常在辐射松下比在牧场下更大;这可能是由于辐射松冠层拦截了空气中的海盐，随后转移到土壤中。速效磷和交换性钾的数据没有总的趋势。总氮含量往往较低，在...
Abstract Some properties of surface mineral soils under Pinus radiata were compared with those under adjacent pasture at ten farm‐forestry sites in the Manawatu, New Zealand. None of the sites had received lime in the last 10 years. Generally, the soil samples under P. radiata had lower pH and higher extractable aluminium concentrations than their counterparts under pasture. Exchangeable calcium values were lower under P. radiata, by 96–1275 kg/ha. Tree uptake and forest floor development can account for up to 550 kg/ha; at six sites the difference was less than 550 kg/ha, suggesting that calcium generally was conserved by the P. radiata ecosystem. Soil exchangeable sodium and magnesium values were usually greater under P. radiata than under pasture; this probably resulted from the interception of airborne sea‐salt by the P. radiata canopy and subsequent transfer to the soil. There were no general trends in the data for available phosphorus and exchangeable potassium. Total nitrogen was often lower in the...
