Lawn Soil N2O Emissions and Microbial Contributions Under Nitrogen Fertilization

Experimental data from an incubation study measuring nitrous oxide (N2O) emissions from lawn soil under different nitrogen fertilizer application rates. The dataset quantifies the contribution of fungi (45%) and bacteria (31%) to N2O emissions and identifies dominant fungal phyla and genera correlated with emission levels. The research was conducted by Zhifeng Xun of Shenyang Agricultural University.

Use Cases

• Modeling N2O emission trends based on nitrogen fertilizer application rates (N0, N150, N225, N300).
• Analyzing the correlation between specific fungal taxa (e.g., Ascomycota, Pyrenochaetopsis) and N2O production.
• Comparing the relative contributions of fungal and bacterial communities to soil greenhouse gas emissions.
• Investigating the impact of nitrogen fertilization on soil microbial community composition.

Strengths

• Quantifies specific contributions of fungi (45%) and bacteria (31%) to N2O emissions.
• Identifies key fungal taxa (Ascomycota, Pyrenochaetopsis, Myrothecium, Humicola) positively correlated with emissions.
• Compares results across four defined nitrogen application treatments (N0, N150, N225, N300).

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• The dataset is derived from a single, controlled incubation experiment; geographic and temporal scope is not specified.
• Data freshness and last update date are unknown.
