Wolf Trax Manganese DDP
Increases Barley Yields in England
®
ISSUE 21: 2016
In 2014, a field study was conducted in England to evaluate the performance
of Wolf Trax Mn DDP as a fertilizer coating and foliar fertilizer in barley
production. The results of this study showed that the combination of
Mn DDP applied to granular fertilizer significantly increased yields when followed
up with a foliar Mn product.
BACKGROUND
Manganese, which is important for photosynthesis and enzyme activity in plants,
is the most common micronutrient deficiency encountered in the United Kingdom.
Manganese availability can be limited in soils that are prone to leaching or drought,
under cold and wet field conditions, or in soils with high pH or high levels of

calcium, iron or phosphorous. Wolf Trax Mn DDP fertilizer is scientifically designed
for better plant availability and earlier uptake of manganese. It is a multi-use
product that can be applied as a fertilizer coating, mixed with liquid fertilizer or
used in-crop as a foliar application.

METHODS
This replicated field trial was conducted by Agrii in the English County of Yorkshire on spring barley planted on
March 21st at a rate of 400 seeds/m2. Soil-applied Mn DDP was coated onto the standard seedbed fertilizer blend
(375 kg/ha of 10-15-21) at 0.4 kg/ha and 0.75 kg/ha respectively, and applied at seeding. Foliar fertilizer applications
were split applied on April 16th and May 23rd. All plots were harvested on August 21st and grain yields were
corrected to 15% moisture content.

SUMMARY
In this study, optimal yields were achieved with a combination of seedbed and foliar Mn applications. Mn DDP
applied to granular fertilizer was beneficial in this study, as Mn DDP Low + Headland Classic resulted in significantly
higher yields than a single application of Headland Classic. Headland Classic performed better than Mn DDP as a
foliar fertilizer in this study, but it is important to note that Headland Classic was applied at 1000 g Mn/ha and foliar Mn DDP
was applied at 198 g Mn/ha.
