Abstract
Soil microbial communities are known to be highly influenced by soil physiochemistry.
By applying organic fertilizers to farmland, agricultural productivity can be increased by increasing the nutrient content of the soil and promoting the growth of microorganisms.
For 4 years in jujube orchard, the effect on soil bacterial community treated with oil cake, one of the organic fertilizers, was compared with chemical fertilizer treatment and evaluated.
Organic fertilizer treatment increased soil calcium and magnesium content compared to chemical fertilizer treatment, but soil organic matter content did not increase.
As a result of the Principal Coordinates Analysis (PCoA), soil bacterial communities were clustered into two groups according to fertilizer treatment.
As a result of analyzing the correlation between the 16s rRNA sequence and soil chemical composition, soil pH, calcium, and magnesium contents showed positive correlations, whereas potassium, electrical conductivity, ammonium nitrogen, and nitrate nitrogen showed significant negative correlations.
Species richness indices (OTUs, Chao, Ace) and species diversity indices (Shannon, Inv-simpson) of soil samples were higher in the organic-fertilizer-treated soils.
In the bacterial phyla, Proteobacteria and Bacteriodetes were more abundant in the organic-fertilizer-treated soil than in the chemical-fertilized soil, confirming that the soil bacterial community composition changed according to the fertilizer treatment.
Therefore, it is thought that the treatment of organic fertilizers can improve the structure and diversity of soil microbial communities along with increasing the nutrient content, such as calcium and magnesium, and affect the growth of plants.
