Yara uses a scientific approach to advise farmers when we promote nitrate-based fertilizers. They are the optimum choice, resulting in higher yields, better quality and lower environmental impacts.
The increase in food production that is essential over the next decades depends on the application of crop nutrients – of which nitrogen is vital. Fertilizer application needs to be balanced: too little and the crop doesn’t reach its full potential; too much wastes resources, hurts the economy and can harm the environment. At the same time, fertilizers carry a carbon footprint cost.
Different sources of mineral nitrogen do not interact the same way with the soil. These differences need to be taken into account when evaluating agronomic and environmental performances.
Nitrogen (N) is a vital element for plant life, stimulating root growth and photosynthesis, as well as the uptake of other nutrients. Nitrate-based fertilizer provides the precision, efficiency and reliability required to meet the agronomic and environmental imperatives of modern agriculture.
Nitrates are absorbed directly by plants, hence we label them Pure Nutrients. Ammonia and urea however, are transformed into nitrate in the soil. Nutrients are lost to the environment during this transformation, making ammonia and urea less efficient.
Nitrates, and nitrate-based compounds, have a significantly lower environmental impact than urea-based products, through reduced leaching, lower volatilization and a lower life-cycle carbon footprint. N fertilizers have a 12.5 percent lower life cycle carbon footprint compared to urea.
Yara’s nitrogen-based crop nutrition solutions have the multiple effect of improving agricultural productivity while reducing environmental pressure and greenhouse gas emissions. Making the right choice about nutrient sources is part of how farmers can approach best farming practice.
With our agronomic expertise and Crop Nutrition Concept, we strongly advocate the optimum use of mineral fertilizers tailored to the crops’ needs.
