Name:

Dose-response profile of degradation of agrochemical using nasturtium

Description:

Estimation of the degradation profile of an agrochemical based on soil samples at depth 0-10cm from a calibration experiment.

Variables:

A data frame with 42 observations on the following 3 variables.

conc: a numeric vector of concentrations (g/ha)
weight: a numeric vector of plant weight (mg) after 3 weeks' growth

Details

It is an experiment with seven concentrations and six replicates per concentration. Nasturtium is sensitive and its weight reduces noticeable at low concentrations.

Racine-Poon (1988) suggests using a three-parameter log-logistic model.
