saltmarsh: Effect of Soil Salinity on Plant Growth
In tigerstats: R Functions for Elementary Statistics

Result of an experiment conducted to investigate the effect of salinity level in soil on the growth of plants.

A data frame with 24 observations on the following 3 variables.

salt: amount of salt applied to the plot (in parts per million)
biomass: total biomass of plot at the end of the study period (units unknown)
block: field in which the plot was located

From the source (see below): "Experimental fields of land were located at an agricultural field station, and each field was divided into six smaller plots. Each of the smaller plots was treated with a different amount of salt (measured in ppm) and the biomass at the end of the experiment was recorded."
