\title{
Assessing erosion risk for certain crops and trees
}
\description{
This function determines risk classes for erosion tolerance for selected agricultural crops and forest trees
}
\usage{
erosionSuit(value, crop)
}
\arguments{
  \item{value}{
Input erosion risk in ton/ha.
}
 \item{crop}{
The crop of interest for which erosion risk class is sought.
}
}
\details{
The input value can be map or just a numerical entry of erosion risk in g/cm3
}
\value{
The output is erosion risk class for the crop. The output is integer value for suitability class: 1- high; 2 - moderate; 3 - low; 4 - very low
