Sulfur Deposition across the United States, 1986-2019 | Video 1 in Sulfur Deficiency in Cotton

This video is published as part of Sulfur Deficiency in Cotton: Causes, Symptoms, and Considerations, a UF/IFAS Extension publication by Hardeep Singh, Ethan Carter, Lakesh Sharma, Sudeep Sidhu, and Peter Omara. Available at edis.ifas.ufl.edu/publication....
The purpose of this article is to provide information to cotton farmers, Extension agents, and crop consultants about the symptoms of sulfur deficiency, the various sources of sulfur, and its interaction with changing rates of other major nutrients such as nitrogen.
VIDEO DESCRIPTION: The National Atmospheric Deposition Program's animated map of the United States depicts the state of sulfur as sulfate ion moist deposition from 1986 to 2019. In the video, the red hue denotes a higher sulfate deposit in kilograms per hectare, while the green color denotes a lower deposit. In 1986, the map showed more red areas, particularly in the eastern part of the country, where sulfate ions might reach 24 kg per hectare. The map gradually becomes greener, with less than 4 kg per hectare by 2019. In Florida, sulfur deposition decreased significantly between 2000 and 2019, from about 20 kg per hectare (17.8 lb per acre) of sulfate to less than 4 kg per hectare (3.7 lb per acre).
