The price of natural gas in the U.S. recently jumped to an all time high and since it represents a major portion of the cost of ammonia production, higher N fertilizer costs are sure to follow. The purpose of this web feature is to provide agronomic information relevant to the impact of higher fertilizer N prices on fertilization decisions and associated crop management. Articles will be added to this page as they become available over the next few weeks. Take a closer look at the relationship between agriculture and the enviroment in this new series from PPI/PPIC ... called Enviro-Briefs. New Topic: Crop Fertilization and Air Quality Improved fertilizer management can help to eliminate most losses of the global warming gases. High, efficiently produced crop yields can actually contribute to a drop in the production and release of global warming gases, particularly CO2, because of crop fertilization. Nutrients Removed in Harvested Portion of Crop The values presented in the following table are estimates of nutrient removal or the quantity of nutrients removed in the harvested portion of the crop. They should not be confused with nutrient uptake which refers to the total nutrients absorbed by the growing crop. Toolbox resources “Toolbox” is a new feature on the PPI/PPIC website which holds free downloadable software tools for improved nutrient management.
