Objectives

(1) Quantify the periodic N emission from a poultry house

(2) Quantify the local spatial variability of accumulated N in the soils and foliage of a developing slash

pine plantation in proximity to poultry houses, with particular attention to the distance of influence

that extends from the poultry house

(3) Quantify the temporal and spatial impact of the forest stand on filter N emissions through the judicious

use of throughfall and minor use of atmospheric collectors

(4) Investigate the relationship between the spatial distributions of accumulated N and pitch canker in

adjacent pine stands
