What is precision agriculture in production?Show answer
Precision agriculture (PA) uses spatial data to manage paddocks at fine resolution rather than treating them as uniform. Core tools include GPS auto-steer on tractors (reducing overlap and operator fatigue), variable-rate technology that adjusts seed and fertiliser rates across a paddock based on soil and yield maps, yield monitors on headers that record harvest data, and remote sensing from satellites and drones to map crop vigour. PA lifts productivity by placing inputs only where they pay, and improves sustainability by cutting wasted fertiliser and fuel, reducing nutrient runoff and lowering emissions per tonne produced.
