Research of some biological properties of agricultural soils of Bafra Plain
Abstract
In this research, 40 soil samples were taken from Bafra Plain, which is one of the two important plains for Black Sea Region, in September 2006, in order to specify the current conditions of the microbiological and biochemical soil characteristics in such a way that they would represent the territory in general. In these soil samples, some enzyme analyzes (acid phosphates, alkaline phosphates, β-Glucosidase, dehydrogenase, urease, and protease enzyme activities), CO2-production, microbial biomass-C, N-mineralization, some physical and chemical analyzes (soil texture, % CaCO3, pH, % total salt, organic matter) were determined and amounts of the available nutrient (P, K, Fe, Cu, Zn and Mn) were also analyzed.
According to the results of the statistical analyzes; organic matter was significantly correlated with all microbiological parameters except protease enzymes activity,
As a result In terms of decreasing the negative effect of decomposition rate of the organic matter, the sustainability of the organic matter will be possible through the incorporating into the soil of plant wastes in soil.
