STUDY OF THE PHYSICAL AND CHEMICAL PROPERTIES OF WATER AND SOILS OF MARSHES AS THESE PROPERTIES RELATE TO THE SUCCESS OF WATERFOWL FOOD AND COVER PLANTS, PART 1
Abstract
Total alkalinity, pH, oxygen and temperature measurements were taken at 6-inch intervals of water depth in each of the 1/10 acre marshes every week during the growing season. The oxygen content ranged from 3.1 to 14.8 ppm during the period from 8:00 A.M. to 5:00 P.M. This change in oxygen level is a reflection of the active biological activity of the marshes. Total alkalinity determinations showed a significant decrease for all marshes. In 1965, 94 percent of all determinations fell in the range of 0.50 ppm. The average alkalinity for the four marshes of any one depth was around 30 ppm. The data from soil tests, taken every 3 months from the bottom soils of each of the marshes showed a trend toward higher levels of iron. The water from the main water supply and the center feeding canal was sampled at weekly intervals throughout the season. These samples were analyzed by spectrographic methods for 15 nutrients. No significant changes from 1964 values were demonstrated.
