Effects of CO2 and Nitrogen Fertilization on Growth and Nutrient Content of Juvenile Ponderosa Pine (NDP-061A)

This data set presents measured values of plant diameter and height, biomass of plant components, and nutrient (carbon, nitrogen, phosphorus, sulfur, potassium, calcium, magnesium, boron, copper, iron, manganese, and zinc) concentrations from a study of the effects of carbon dioxide and nitrogen fertilization on ponderosa pine (Pinus ponderosa Dougl. ex Laws.) conducted in open-top chambers in Placerville, California, from 1991 through 1996. This data set contains values from 1991 through 1993.

本数据集收录了一项针对二氧化碳与氮肥施加对美国黄松（Pinus ponderosa Dougl. ex Laws.）影响的研究实测数据，涵盖植株径高、各组分生物量以及碳(carbon)、氮(nitrogen)、磷(phosphorus)、硫(sulfur)、钾(potassium)、钙(calcium)、镁(magnesium)、硼(boron)、铜(copper)、铁(iron)、锰(manganese)、锌(zinc)等营养元素的浓度值。该实验于1991年至1996年间在美国加利福尼亚州普莱瑟维尔的开顶式气室(open-top chambers)中开展，本数据集仅包含1991年至1993年的实测数据。
