Nitrogen fertilizer use in agriculture has been increasing; unfortunately, the same is true for nitrogen losses to the environment. Weather, as well as the frequency and timing of nitrogen applications, can affect how efficiently nitrogen is used by the crop to produce yield and how much is lost. One way to improve nitrogen fertilizer use in corn is to split the application so that some is applied at planting and the rest is applied in the growing crop. Farmers can then adjust the rate and timing of the second application depending on the weather.
Phosphorus is an essential nutrient for plant growth – including the algae that grow in rivers and lakes. When phosphorus is lost from agricultural soils into waterways, it can allow algae to grow rapidly, which causes problems for fish and humans.
