Cover Crop Effects on Soil Health and Grape Yield in Spanish Vineyards, 2021-2022

Four soil management systems were compared in a Spanish Tempranillo vineyard, showing a 75% yield decrease under a flower cover crop and a 57% increase in Soil Organic Carbon under a grass-legume cover. The dataset, authored by Andrea Martín-Pablo and last updated in 2026, likely contains soil property measurements, grape yield, and quality data from a 2021-2022 study assessing trade-offs between ecosystem services and agricultural production.

Use Cases

• Modeling the relationship between cover crop type and grape yield based on reported 75% yield reduction under flower cover crops.
• Analyzing soil organic carbon sequestration potential based on the reported 57% increase under sown grass-legume mixtures.
• Investigating trade-offs between grape quality (e.g., anthocyanin content) and nutrient availability (e.g., nitrate depletion) under different ground covers.
• Comparing the effects of conventional tillage versus natural or sown cover strategies on soil microbial biomass and enzymatic activity.

Strengths

• Data is derived from a structured, randomized block design experiment with four replicates per treatment.
• Specific quantitative findings are reported, such as a 57% increase in Soil Organic Carbon and a 75% yield decrease for certain treatments.
• Covers multiple assessment dimensions: soil chemistry, biology, grape production, and biodiversity.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (33.7 KB), indicating limited scope, likely a summary table or document.
