SULFUR RESEARCH: WE NEED YOUR HELP
Contact:
If you are interested in participating (even if you are not sure whether your particular field or equipment would fit the conditions for this study), or if you have question about how to find sulfur fertilizer or have the fertilizer applied please contact Fabián Fernández: [email protected] ; phone, 217-333-4426; Department of Crop Sciences, N-315 Turner Hall MC-046, 1102 South Goodwin Ave., Urbana, IL 61801.
Soil conditions:
We are interested in light color soils (less than 2% organic matter, coarse texture, or both) and soils with an eroded phase. However, we would like to characterize sulfur response across the State, so we will consider other “more traditional” soils in Illinois as well. Fields that will not be considered in the study are those that have received manure or sulfur applications within the last 5 years.
Equipment:
Volunteers conducting these trials will follow a simple design applying 0 and 30 lb S/acre as a broadcast application in a uniform portion of the field. A minimum of three replications or as many as 8 replications are needed for each field. Figure A shows a layout of the treatments randomly assigned within each replication for an 8 replication study. It will be important to georeference or clearly mark each strip with different color flags or markers in the center of each strip. Strips can be anywhere from 8 to 16 rows wide by 300 to 1,000 feet long. What is important is that the size of the strip allows accurate application of the rate, accurate measurement of yield, and if possible that the strips are wider than the harvest strip. However, if the combine is at least 12 to 16 rows wide it is possible to harvest the strip without having border rows.
Sulfur sources:
Sulfur sources will be limited to either ammonium sulfate (NH4)2SO4 (21-0-0-24); MicroEssentialsTM sulfur (ME S) ME S15 (13-33-0-15); and elemental sulfur (0-0-0-90). If the sulfur source contains other accompanying nutrients, the corresponding rates of those nutrients will need to be applied to other treatment strips to avoid a differential response to nutrients other than sulfur. If you use ammonium sulfate you would need to apply 26 lbN/acre to the other strips and if you use ME S15 you would need to apply 145 lb DAP (18-46-0)/acre (for more details see section below “How to apply the treatments”).
Time of application:
The preferred application time is the spring (pre-plant), but if the only time available is the fall, we can certainly accommodate it. What is most important is to try to have as many locations as possible throughout the state to be able to characterize the potential for corn response to sulfur in Illinois.
Measurements for data collection:
The only data volunteers will have to provide is the yield for each strip. This information can be collected by yield monitor or from a weigh wagon. Volunteers will not be required to take plant or soil samples, but would need to allow the researcher to visit the strips approximately two to three times during the growing season.
