Data from experiments with tailing material and Agrostis capillaris at three scales: pot, lysimeter and field plot

Area of Science:

• Environmental Science
• Ecology
• Soil Science

Background:

• Phytostabilization of mine tailings is crucial for environmental remediation.
• Understanding plant growth dynamics on heterogeneous substrates is key for successful revegetation.

Purpose of the Study:

• To present a dataset detailing Agrostis capillaris growth on tailings across multiple experimental scales.
• To provide data for analyzing the influence of substrate heterogeneity and temporal scales on phytostabilization.

Main Methods:

• The dataset comprises two matrices: one detailing experimental variants of Agrostis capillaris (297x46) and another on plant species cover (12x24).
• Data originates from three experiments conducted at different scales but using identical variants, with experimental origin coded.
• The dataset facilitates analysis of plant growth and species cover in relation to experimental conditions.

Main Results:

• The dataset captures plant growth responses of Agrostis capillaris under varied tailing substrate conditions.
• Relative plant species cover data is provided for experimental field plots.
• The data supports the interpretation of how spatial and temporal factors influence phytostabilization outcomes.

Conclusions:

• The presented data is essential for researchers and practitioners in phytostabilization.
• This dataset enables detailed analysis of vegetation establishment on challenging substrates like mine tailings.
• It contributes to optimizing phytostabilization strategies by integrating scale-dependent ecological processes.
