Chlorophyll concentration

Description

An experiment with winter wheat was carried in order to investigate if the concentration of nitrogen in the soil can be predicted from the concentration of chlorophyll in the plants. The chlorophyll concentration in the leaves as well as the nitrogen concentration in the soil were measured for 18 plants.

Format

A data frame with 18 observations on the following 4 variables.

1. chloro: chlorophyll concentration in leaves
2. nit: nitrogen concentration in soil
3. log.nit: the logarithmic transformation of nitrogen concentration in soil
4. sqrt.nit: the square-root transformation of nitrogen concentration in soil

Experiment was carried out at the Royal Veterinary and Agricultural University in Denmark.
