GYPSUM COUNTERACTS SALT IN ROADSIDE SOIL TESTS

A TWO-YEAR RESEARCH PROJECT CARRIED OUT BY THE UNIVERSITY OF MAINE, FINDS THAT GYSPSUM WHEN APPLIED TO ROADSIDES SUBJECT TO WINTER ROAD SALT, EFFECTIVELY REDUCES THE SODIUM LEVEL IN THE SOIL. THE GYPSUM WAS APPLIED IN DIFFERENT AMOUNTS TO A MAXIMUM RATE OF 14 TONS PER ACRE. SOIL SLMPLES WERE TAKEN FOR ANALYSIS BEFORE AND AFTER TREATMENT; SAMPLES AS WELL WERE TAKEN FROM UNTREATED PLOTS OF GROUND. THERE WAS A SIGNIFICANT REDUCTION IN THE SODIUM LEVEL DURING THE PERIOD OF THE TEST WHERE GYPSUM WAS APPLIED. GYPSUM REMAINS IN PLACE BECAUSE OF ITS LOW SOLUBILITY UNDER MAINE WEATHER CONDITIONS, HENCE ITS EFFECT SHOULD BE LONG LASTING. BASED ON A REVIEW OF MAINTNENACE ACTIVITIES, SALT STORAGE FOR HIGHWAY USE HAS BEEN CHANGED FROM AN OUTSIDE PAD WITH WOODEN SIDEWALLS AND CANVASS COVER, TO COMPLETE INSIDE STORAGE INCLUDING PAVED FLOOR AND FOUR-FOOT SIDEWALLS AND WOODEN ROOF. /AUTHOR/
