Plant-soil feedback drives the nursing effect on Sitka spruce

The productivity of economically valuable focal trees in mixtures is often improved by inclusion of lower- value nursing species, but the mechanisms underpinning such effects are poorly resolved. This gap in understanding limits the capacity to develop efficient planting strategies for forests and woodlands to contribute to net-zero and other critical ecosystem functions. Here, we undertook a plant-soil feedback experiment to test the hypothesis that feedback effects improve the biomass of Sitka spruce (Picea sitchensis (Bong.) Carr) in soil conditioned by monocultures of heterospecific nurse species, and a mixture comprising Sitka spruce and heterospecifics, compared to soil conditioned by only Sitka spruce. Sitka spruce saplings had greater biomass in soil conditioned by Scots pine monocultures (Pinus sylvestris L.) and the mixture compared to their own soil or soil conditioned by silver birch (Betula pendula Roth). Statistical models showed that colonisation of ectomycorrhizal fungi ..., , , # Plant-soil feedback drives the nursing effect on Sitka spruce [https://doi.org/10.5061/dryad.4tmpg4fmh](https://doi.org/10.5061/dryad.4tmpg4fmh) ## Description of the data and file structure Author: Yichen Zhou, University of Manchester Contact: [[e-mail]](mailto:[e-mail]) Date:2024/11/13 Contains material related to the paper: Plant-soil feedback drives the ‘nursing effect’ on Sitka spruce.

Carr）自身培育的土壤，经异种保育树种单作培育的土壤，以及西加云杉与异种树种混作培育的土壤，其反馈效应可提升西加云杉的生物量。 与仅以西加云杉培育的土壤或银桦（*Betula pendula* Roth）培育的土壤相比，西加云杉幼苗在苏格兰松（*Pinus sylvestris* L.）单作培育的土壤及混作土壤中生物量更高。统计模型显示，外生菌根真菌的定殖…… # 植物-土壤反馈驱动西加云杉的“保育效应” https://doi.org/10.5061/dryad.4tmpg4fmh ## 数据与文件结构说明 作者：周亦辰，曼彻斯特大学 联系方式：[e-mail] 日期：2024/11/13 本数据集关联以下论文：《植物-土壤反馈驱动西加云杉的“保育效应”》，作者：周亦辰、陶婷婷、Filipa Cox、David Johnson 说明：本自述文件用于说明上述论文关联的模型代码。所有单位与方法细节均已在论文中阐述。 ### 文件与变量 #### 文件：Zhou_et.al-data.xlsx **文件说明：** 本研究已将全部数据整合至"Zhou_et.al-data.xlsx"，该文件包含多个工作表：其中"Plant properties（植物性状）"工作表收录反馈阶段后的植物性状数据；"Condition soil（培育土壤）"工作表收录培育阶段后的土壤性状数据；"PSF（植物-土壤反馈）"工作表……
