Data from: Drivers of available phosphorus distribution patterns in mangrove wetland soils and modeling of the influencing pathway of glomalin-related soil proteins

There are three files(.csv) in DATA dataset, which are phosphorus content data, environmental factors data and iron content data. They are used to reveal the distribution pattern of available phosphorus in mangrove soil and the key causal factors. The Code/Software dataset includes two files, a code text for random forest analysis; and a code text for structural equation modeling. The former was used to rank the environmental factors affecting available phosphorus content in order of importance; the latter was used to explore the influence pathways of glomalin-related soil protein on available phosphorus.<b>Description of the data and file structure</b>The first row of each data file is the variable name, and the first column is the sample sites name. KO represents data obtained from K. obovata forest soil; AM represents data obtained from A. marina forest soil; and MF represents data obtained from mudflat soil. yEr represents the standard error of the data.<b>phosphorus data.csv </b>The file includes 9 sets of data. They are the content of soil total phosphorus (SOIL-TP), the content of phosphorus in GRSP (GRSP-P), the content of Olsen-P, the content of four biologically based P (CaCl2-P, HCl-P, Citrate-P, Enzyme-P), the contribution rate of GRSP to TP, and the contribution rate of AP (Olsen-P) to TP.<b>environmental factor data.csv </b>The file includes 11 sets of data. They are soil depth, the percentage of three particle sizes (clay, silt, sand), pH, the percentage of soil total carbon (TC), the percentage of soil total nitrogen (TN), the soil organic carbon content (SOC), the glomalin-related soil protein content (T-GRSP), the soil organic matter's carbon-to-nitrogen ratio (SOM-C/N), the glomalin-related soil protein's carbon-to-nitrogen ratio (GRSP-C/N).<b>Fe data.csv </b>This file consists of three data groups, which are the content of soil exchangeable iron (Exchangeable Fe), the content of soil total iron (Soil-Fe) and the content of iron in glomalin-related soil protein (GRSP-Fe).<b>Code/Software</b><b>randomForest.txt </b>loaded packages: ggplot2, tidyverse, randomForest, rfUtilities, and rfPermutesoftware versions: R4.2.3<b>pSEM.txt</b>loaded packages: piecewiseSEM, readxlsoftware versions: R4.2.3
