Greenhouse Soil and Tomato Yield Data from Long-term Straw and Biochar Application

A study investigates the effects of long-term organic amendments on soil properties and tomato yield under continuous greenhouse cultivation. The dataset includes measurements of soil carbon fractions, enzyme activities, and yield increases from treatments with straw, biochar, and their combination. The data was published by Xiaoyang Yu on figshare in April 2026.

Use Cases

• Modeling the relationship between particulate organic carbon and crop yield based on structural equation modeling results
• Comparing the effects of different organic amendments on soil pH and bulk density
• Analyzing changes in soil enzyme activities (e.g., catalase, glucosidases) after organic material addition
• Evaluating the impact of soil carbon fractions (DOC, ROC, MBC, POC) on agricultural productivity

Strengths

• Includes specific percentage increases for key soil carbon fractions (e.g., 102.56%-196.93% for POC) and tomato yields (e.g., 22.61% for straw treatment)
• Reports precise changes in soil pH (4.10% and 6.10% increases for biochar treatments)
• Based on long-term field observations, providing longitudinal data on treatment effects

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• The dataset is small (272.5 KB), indicating limited scope or a summary of results
