height_canopy = 2 ## this value is the maximum of Height_canopy_function.
ground_area = 10000 ## generally is one hectare in m^2.
row_spacing = 2.9 ## measured in meters.
## The function is currently defined as
function(height_canopy,ground_area,row_spacing){
LWA <- 2* height_canopy * (ground_area/row_spacing)
