Assessment of the relationship between some physico-chemical properties of soil and soil algae in micro basin scale in Kocaeli

Abstract

In this study, it was aimed to determine the relationship between soil algae and physico-chemical structure of soil. Algae composition and some soil quality parameters from 12 sampling stations were investigated between March 2019 and May 2019 in Kocaeli. Physico -chemical properties that reflect soil nutrient content and fertility status (pH, conductivity, salinity, CaCO3, organic matter, saturation, P2O5 and K2O) were determined using standard physicochemical techniques. Average in soil parameters were determined as pH: 8.06, conductivity: 5.79 mu mhos / cm, salinity: 0.22 parts per thousand, CaCO3: 9.98%, organic matter: 1.70%, saturation: 59.55%, P2O5 : 3.16 kg / da, K2O: 93.92 kg / da. Algal flora of Kocaeli province was a total of 30 taxa, 14 taxa of Bacillariophyta, 3 taxa of Chlorophyta, 1 taxa of Charophyta and 12 taxa of Cyanobacteria were identified. The determined as the Chroococcus cohaerens, Limnococcus limneticus, Phormidium nigroviride, Oscillatoria limosa, Gomphonema olivaceum, Hantzschia amphioxys and Nitzschia brevissima most dominant taxa. These taxa have been identified in stations with high industrial activity. Bacillariophyta taxa were found in all months due to their ecological tolerance, while other species belong to spring. In this study, the species diversity were found similar in research stations.
