BURBS Spreadsheet (nitrogen mass balance)

BURBS is a Lotus 1-2-3 version 2 spreadsheet that helps you to construct a nitrogen mass balance for a residential area in a place like Long Island. Much of the U.S. Atlantic Coastal Plain is similar to Long Island:

* Significant surplus of precipitation over evapotranspiration.
* High soil and subsoil infiltration rates.
* Flat terrain, leading to very little overland runoff except from impervious surfaces.
