High-Carbon Bio-Organic Fertilizer Effects on Soil Aggregates and Carbon Fractions

This dataset originates from a field experiment comparing four fertilizer treatments: chemical fertilizer (CK), organic fertilizer (OF), bio-organic fertilizer (BOF), and high-carbon bio-organic fertilizer (HBOF). It measures effects on soil aggregate size distribution, organic carbon fractions like particulate organic carbon (POC) and microbial biomass carbon (MBC), and bacterial community composition in red soil.

Use Cases

• Analyze the relationship between fertilizer treatment and the proportion of soil aggregates larger than 2 mm, which increased by 8.58% and 6.87% for HBOF versus OF and BOF.
• Model the impact of HBOF treatment on active carbon fractions, specifically the 15.83% increase in particulate organic carbon (POC) and 24.05% increase in microbial biomass carbon (MBC) compared to BOF.
• Investigate shifts in bacterial community composition, such as the enrichment of genera like Pantoea and Bacillus, and correlate them with changes in carbon fractions and aggregate properties.
• Compare soil carbon storage and aggregate stability metrics across the four defined fertilizer treatments (CK, OF, BOF, HBOF).

Strengths

• Data is derived from a controlled field experiment with four distinct fertilizer treatments, providing a structured comparison.
• Includes specific, quantified results such as an 8.58% increase in >2mm aggregates for HBOF over OF and a 15.83% increase in POC for HBOF over BOF.
• Covers multiple analytical dimensions: soil physical structure (aggregates), carbon chemistry (fractions), and microbiology (bacterial communities).

Limitations

• The dataset is presented as a 280.5 KB PDF, indicating it is likely a summary of results rather than raw, tabular data suitable for direct computational analysis.
• Sample size, geographic scope, and temporal coverage of the underlying field experiment are not specified in the provided description.
• Data granularity is limited to reported summary statistics and percentages; raw measurements or replicate-level data are unavailable.
