USA		Link is from Purdue.
https://www.agry.purdue.edu/ext/corn/news/timeless/sulfurdeficiency....

Says 200 bu corn contains 10 lbs Sulfur. Says if ground is low on sulfur apply 15 lbs S on fine soil, 25 lbs S on coarse soil.

Pioneer link says 16 lbs S for 200 bu corn.

Pioneer link also shows each lb of AMS and elemantal sulfur burns 7.2 lbs of lime per lb. ATS is 5.4 lbs of lime.

Here is another from U of I says 230 bu corn had uptake of 23 lbs of S, grain removal was 13 lbs S.

AMS is a high priced way to buy N, if AMS is not usable. Other thing with AMS if you study what the experts say that have credibility. Corn needs most of it's S later in corn life cycle. appears to me applying Sulfur in a small band @ side dress looks to be a more efficient way to provide sulfur to the corn plant when needed vs broadcasting before the corn is planted @ much higher rate and cost.
