Temporal changes in plant soil feedbacks between the invasive Phytolacca americana and congeneric native and non-invasive alien plants

The direction and intensity of plant-soil feedbacks (PSFs) and the reciprocal effects between plants and soils can change over time. PSFs can also affect competition between invasive and native plants. However, most PSF research is conducted in simple experimental settings where temporal changes are not considered. Few studies have assessed the temporal dynamics of PSFs among invasive plants, newly introduced plants, and native plants. Here, we conducted a two-stage PSF experiment to evaluate the temporal dynamics of PSFs among the invasive alien Phytolacca americana, the non-invasive alien Phytolacca icosandra, and native Phytolacca acinosa. We conducted the experiment with different conditioning time periods. First, we planted the three species individually in pots to condition the soils. Then, each species was grown in a pot conditioned by the same species (“home soil”) or pots conditioned by one of the other two species (“away soil”). Invasive and native plants produced higher bioma..., , , # Data from: Temporal changes in plant soil feedbacks between the invasive Phytolacca americana and congeneric native and non-invasive alien plants

## Description of the data and file structure

## Files and variables

#### File: PSF-conditioningphase\_soil\_properties.xls

**Description:** Soil properties observed at the conclusion of the conditioning phase.

##### Variables

* rep: number of experimental replicates
* condition_trt: different condition treatments in the condition phase. We use different plants to condition the soil (CK-no plant treatment, Invasive-invasive plants, Alien-non-invasive alien plants, Native-native plants)
* time: duration of the condition time (months)
* NH4-N: the ammonia nitrogen content in the soil (mg/kg)
* AP: the available phosphorus content in the soil (mg/kg)
* Nitrogenase: a type of soil enzyme activity, nitrogenase is an enzyme that converts atmospheric nitrogen ...
