MicroEssentials® Cotton Study


Evaluate the yield response of cotton to DAP, MicroEssentials® S10® and MicroEssentials® SZ®.


  • Diammonium phosphate (DAP) is a common phosphorus source used on cotton.

  • Adequate availability of sulfur (S) and zinc (Zn) is critical for maximum cotton yield.

  • MicroEssentials® S10® and MicroEssentials® SZ® supply multiple nutrients fused into one nutritionally balanced granule, promoting uniform nutrient distribution, season-long S availability, improved nutrient uptake and increased yield.


Locations and Crop Management:

Crop: Cotton (Gossypium hirsutum L.)

Years: 2016-2017

Locations: 8 trials across the United States – GA, MS, NC, SC, TN, TX

Data Source: Field studies conducted by third-party, independent researchers.

Experimental Design: Small-plot RCBD with 4 replications.

Cropping Conditions: All trials conformed to local cropping practices.

P Rate: 50 lbs P₂O₅/ac applied as DAP (18-46-0), MicroEssentials® S10® (12-40-0-10S) or MicroEssentials® SZ® (12-40-0-10S-1Zn)

S Rate: 12.5 lbs S/ac from the MicroEssentials® treatments

K Rate: As required by soil test

Application Timing: Preplant

Application Method: Broadcast incorporated


Cotton Lint Yield


  • MicroEssentials® S10® increased cotton lint yield by 43 lbs lint/ac over DAP.

  • MicroEssentials® SZ® increased cotton lint yield by 51 lbs lint/ac over DAP.

  • Higher cotton lint yields achieved by using MicroEssentials® demonstrate the value of uniform nutrient distribution, season-long S availability and increased nutrient uptake.

Individual results may vary, and performance may vary from location to location and from year to year. This result may not be an indicator of results you may obtain as local growing, soil and weather conditions may vary. Growers should evaluate data from multiple locations and years whenever possible.
