MicroEssentials® S10® — Cotton Study


Evaluate the yield response of cotton to DAP (18-46-0), DAP + AS (21-0-0-24S), and MicroEssentials® S10® (12-40-0-10S).


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

  • University research highlights the need for sulfur (S) management on cotton and the importance of season-long availability (See Figure.1).

  • MicroEssentials® S10® supplies multiple nutrients fused into one nutritionally balanced granule, promoting uniform nutrient distribution, increased nutrient uptake, a season-long S availability and higher yields.

Crop: Cotton (Gossypium hirsutum L.)

Years: 2016-2018

Locations: 12 trials across 5 states - GA, MS, NC, SC, TN

Data Source: Field studies conducted by independent third-party 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) or MicroEssentials® S10® (12-40-0-10S)

S Rate: 12.5 lbs S/ac from AS or MicroEssentials® S10®

Application Timing: Spring Preplant

Application Method: Broadcast incorporated


Cotton Yield Res


  • MicroEssentials® S10® increased cotton yield by 61 lbs lint/ac over DAP and 18 lbs lint/ac over DAP+AS.

  • The results show that while lint yields increased with the addition of sulfate-sulfur, even better yields can be achieved when a season-long supply of S (sulfate + elemental) is provided.

  • Higher cotton yields achieved by using MicroEssentials® S10® demonstrates the value of uniform nutrient distribution, increased nutrient uptake, and season-long S availability.

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.
