Traditional farming remains the most widely used approach across Europe for a simple reason: why fix something that isn’t broken? The tools are dependable, inputs are easy to source, and the routines passed down through generations have delivered stable results for decades. In a period of rising input costs, shifting market demands, and tightening policy requirements, familiar methods offer farmers a sense of stability in an increasingly unpredictable agricultural landscape.
But even these trusted practices are being tested by today’s changing conditions. Irregular rainfall, sudden storms, long dry periods, and evolving environmental regulations are making nutrient management harder to predict. Fertiliser that once reliably fed crops is now more easily washed into ditches during heavy rains, leached into groundwater, or lost as nitrous oxide gas. Research shows that increases in fertiliser use directly raise agricultural nitrous oxide emissions—a greenhouse gas nearly 300 times more potent than CO₂—with a 10% increase in fertiliser consumption driving a 3.09% rise in nitrous oxide emissions globally. At the same time, more fertiliser use increases agricultural freshwater withdrawals by over 15%, placing additional pressure on water supplies. What was once a reliable aid is now, under new climate realities, also contributing to soil imbalance and long-term environmental strain.
The environmental impacts of excessive fertiliser use
When fertilisers or manures are applied in excess or under unstable weather conditions, they move beyond the root zone and enter surrounding ecosystems. According to NDSU Extension, nutrients such as nitrogen (N) and phosphorus (P) travel with runoff water or eroded soil particles into streams, wetlands, and lakes, where they accumulate and fuel rapid algae and weed growth. This process—eutrophication—leads to algal blooms that block sunlight and dramatically reduce dissolved oxygen as they decompose. Low oxygen levels ultimately suffocate fish and other aquatic species, causing fish kills and long-term water quality decline, as documented in multiple U.S. and global cases.
Beyond aquatic systems, these nutrient losses carry significant soil implications. Excess nitrogen inputs acidify soils, disrupt microbial communities, and reduce organic matter over time, lowering the soil’s natural ability to retain water and nutrients. At the atmospheric level, nitrous oxide emissions from fertiliser application continue to rise. Paudel’s global analysis confirms that increasing fertiliser use not only boosts yields but also increases greenhouse gas emissions and freshwater withdrawals, demonstrating the environmental cost associated with fertiliser inefficiency.
Together, these findings underline a central challenge: even responsible fertiliser use becomes environmentally risky when weather patterns shift and application precision becomes difficult to maintain.
How AgRibot brings precision to the field
As fertiliser losses grow harder to control and environmental expectations continue to rise, interest is turning toward tools that can deliver greater accuracy without disrupting the way farms already operate.
Across the trial sites, AgRibot is working with growers to test machines that can apply inputs only where they are needed. In broad-acre cropping systems, for example, camera-guided sprayers are being used to identify weeds or unwanted plants in real time and treat them individually, allowing operators to cut back on blanket applications while still keeping fields clean. Trials in open-field vegetables are looking at whether sensor-equipped platforms can measure crop growth and nutrient demand closely enough to guide more accurate fertiliser applications — the kind that stay in the root zone instead of washing away after a heavy rain. And in greenhouse tomato production, autonomous units are gathering steady streams of growth and fruit-quality data, helping growers fine-tune feeding programmes throughout the season. Taken together, these trials show how robotics can support a more precise use of fertiliser and crop protection products — helping reduce runoff, limit waste, and keep soils productive for the long term. Rather than replacing established practices, the technology is being tested as a way to reinforce them, giving farmers clearer insights into crop needs at a time when both weather patterns and regulations are shifting.
