Study: Nu-Trax P+ on lettuce production

By Wolf Trax

Nu-Trax P+® (4-25-0, 5% Mn, 20% Zn) coats each granule of a dry fertilizer blend, placing highly available, critical nutrients closer to plant roots.

OBJECTIVE
Determine the effect of Nu-Trax P+ on ‘Crusader’ iceberg head lettuce yield, sizing, and nutrient uptake.

TRIAL DETAILS
Nu-Trax P+ was applied as a dry powder to coat a fertilizer blend carrier. This treatment was compared to the grower standard practice (GSP). Trial design was a small plot RCBD with 4 replications. Trial work was completed by Dr. Bielinski Santos, in Gilroy, CA.
