OVERVIEW
-
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.
TRIAL DETAILS
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
Results
SUMMARY
-
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.
