Argentina tests drones to cut fertiliser use

Researchers from Argentina’s Instituto Nacional de Tecnología Agropecuaria (INTA) reported that the use of multispectral drone imaging in field trials allowed farmers to significantly reduce nitrogen fertiliser use without affecting crop performance.

The trials focused on adjusting fertiliser application rates based on detailed aerial data collected by drones. By identifying differences in crop growth and nutrient needs across fields, the technology enabled more precise fertilisation decisions.

According to INTA, the approach reduced nitrogen use by more than 50% compared with conventional uniform application methods, while crop productivity remained stable throughout the testing period. The results highlight the potential of precision agriculture tools to optimise input use and improve farm efficiency.

Researchers noted that fertiliser represents one of the largest production costs for growers, making targeted application strategies increasingly important as input prices and environmental pressures continue to rise. The technology also supports sustainability goals by limiting excess nutrient use and reducing the risk of soil and water contamination.
