Variable Rate Application — Site-Specific Input Management in Agronomy

Variable Rate Application (VRA) is a precision agriculture technique that adjusts the quantity of inputs — such as fertilisers, pesticides, seeds, or water — across different zones of a field based on georeferenced soil and crop data. Rather than applying a uniform rate across an entire field, VRA delivers the right input, at the right rate, in the right location, improving resource efficiency and reducing environmental impact in crop production systems.
