Abstract
The present study examined the role of moisture on the soil respiration rate in forest soils supplemented with two different types of polymeric superabsorbents. Soil samples were collected in the Tyniecki Forest near Krakow, Poland. The physicochemical characteristics of the soils were studied, as well as the basal soil respiration rate under standard substrate moisture conditions, which is 60% of the maximum soil water capacity. An experiment was conducted in which two different types of polymeric superabsorbents (SAP) were added to the soils: SAP 1, a classic representative of synthetic acrylic polymers, and SAP 2, a copolymer based on oxidized starch and acrylic acid. To accomplish the research objective, moisture conditions of the studied samples were determined - simulated variants of constant optimal moisture, normal sediment followed by dry conditions, and over-gravel sediment followed by dry conditions. The experiment had 2 dry-rain cycles. During the experiment, changes in the soil respiration rate were measured. The study concluded that soil moisture and the role of SAP are of paramount importance - the maximum soil respiration rate was achieved under conditions of constant soil moisture at 60% WHC and under conditions of over-gravel precipitation and subsequent drying - in these variants, the soil had sufficient moisture due to hydrogels. SAP 2 performed better than SAP 1 - this is due to the chemical structure of the hydrogel, where oxidized starch played the role of an additional easily digestible carbon substrate for soil microorganisms.
