This tool allows users to create a manure prohibited area (Drawing Manure Prohibited Areas) around custom features such as points, lines, and polygons. To start go to Drawing Tools - Draw a Feature - Manure prohibited area  by buffering custom feature. You should now see a dialog with a box to input the width in feet you want to buffer the field boundary along with the type of feature you want to draw and then buffer. You can create more than one feature by drawing a feature than either drawing another feature or changing the type of feature and drawing it. Once you have drawn all the features to buffer click the button Buffer the Features. Your new Manure Prohibited Areas should appear.
