Precision Agriculture

Precision agriculture tools integrate high-resolution geospatial data — LiDAR, multispectral imagery, soil surveys, and yield maps — to support evidence-based farm management decisions. These are specialised Pro tier workflow tools that automate complex multi-source analyses into actionable management zones and field intelligence reports.

Key Concepts

• Management Zones: Spatially delineated areas of a field that share similar soil, crop, or topographic characteristics, enabling variable-rate application of inputs such as fertiliser, seed, or irrigation water.
• Yield Data Conditioning: Raw yield monitor data contains significant noise and artifacts; conditioning standardises and quality-controls it before analysis.
• Crop Stress Detection: Using multispectral imagery (NDVI, NDRE, CWSI) to identify in-season stress before visible symptoms appear, enabling targeted intervention.
• Field Trafficability: Assessing soil compaction risk and field access conditions based on soil moisture models and terrain analysis.

Tool Reference

The tools in this chapter are accessible from the QGIS Processing Toolbox under Whitebox Workflows → Precision Agriculture.
