j ENTER	Slope (%)		k Read Down
	Length (FT)

WIDTH (FT)	m	l Field Application Area


1. Enter at slope of field application area from Appendix D.
2. Read down column and find corresponding length of field application area.
3. Continue down column stopping at area closest to that previously calculated for your site.
4. Read left to find width of field application area.
