Cotton-Wheat System Soil-Plant Metrics Under Subsurface Fertigation

Figshare hosts a study by Kulvir Singh on subsurface drip fertigation in cotton-wheat rotations. The dataset includes measurements of Root Length Density, Net Photosynthesis, Leaf Area Index, Infiltration Rate, and Bulk Density from two growing seasons under reduced tillage.

Use Cases

• Analyze correlations between soil Bulk Density and plant physiological metrics like Net Photosynthesis and Stomatal Conductance.
• Model the impact of fertigation strategies on crop productivity using Root Length Density and Leaf Area Index as predictors.
• Compare Infiltration Rate and Bulk Density across different subsurface drip configurations and irrigation depths.

Strengths

• Includes five specific, measured variables: Root Length Density, Net Photosynthesis, Leaf Area Index, Infiltration Rate, and Bulk Density.
• Data collected over two growing seasons, providing comparative temporal observations.
• Study investigates multiple SDF configurations, including lateral placement depth and emitter spacing.

Limitations

• Dataset is very small (55.9 KB), indicating a limited scope likely focused on summary results rather than raw observational records.
• Unknown row and column structure; data is embedded within a DOCX document, complicating direct analysis.
• Geographic and soil context for the field experiment is not specified, limiting generalizability.
