A dataset of rice root biomass and rice root nutrient content observed by Taoyuan Agro-ecosystem Research Station of Chinese Academy of Sciences during 2005-2018

Abstract

Rice root residue in soil is one of the primary contributor to the organic matter content in paddy soil, and it also plays an important role in maintaining the stability of organic carbon content in paddy soil. This dataset collects the rice root biomass in top soil and the root nutrient from 6 long-term monitoring plots (one comprehensive observation field, three complementary observation fields, namely 3 fertilization treatment sites, and two investigation stations) of Taoyuan Agroecological Experimental Station of Chinese Academy of Sciences from 2005 to 2018. The plots include The dataset consists of 7 parts: surface root biomass (0-20 cm), root nutrient content (including total carbon, total nitrogen, total phosphorus, total potassium), root distribution biomass (0-10 cm, 10-20 cm, 20-30 cm, 30-40 cm), background information of the sample plots, fertilizer input in the sample plots, sampling records, and analysis method records. The generation of data is strictly in accordance with the CERN biological network monitoring specifications, and the data quality has been reviewed by quality control personnel from both from both the station and the sub-center. This dataset will provide reliable basic data for exploring the contribution of rice roots to soil organic carbon, nitrogen, phosphorus and potassium levels in paddy fields, as well as the role of rice roots in preserving soil fertility.
