Wolf Trax™ DDP® Nutrients Increase Yields in Rwanda Part 3: Wheat
Wolf Trax DDP Nutrientsfeature three proprietarytechnologies that ensureeffective delivery of nutrition:
EvenCoatTM
Technology
Fertilizer coating technologyallows for blanket-likedistribution and more points ofinterception for young roots.
PlantActivTM
Formulation
Physically and chemicallydesigned – the Wolf Trax DDPparticle size is optimum forplant uptake.
Wolf Trax Innovative Nutrients are unique, research-tested and field-proven micronutrient and secondary nutrientfertilizers. By making nutrients more accessible to plants when they are needed most, Wolf Trax products simplifynutrient management, boost crop performance and enhance the return on farmers’ fertilizer investment.

DUAL ACTIONTM
Each DDP Nutrient is formulated with atleast two forms of the mineral, providingimmediate nutrient uptake as well asextended feeding over time.
In 2015, a multi-site, replicated field trial was conducted in Rwanda to
evaluate the performance of Wolf Trax DDP Nutrients as part of an early
season fertiliser program for wheat production. Alternate micronutrient
strategies were also implemented for comparison purposes. Under the conditions
of this study, micronutrient strategies including Wolf Trax DDPs resulted in
significantly higher wheat yields than the current fertiliser practice.
BACKGROUNDSoil fertility is often a limiting factor in crop production throughout Rwanda due to
erosion and parent material that is inherently low in nutrient content, and soils often
require high levels of soil amendments in order to optimize crop production. Interest
in application of micronutrient fertilisers to complement current fertiliser practices
has increased in recent years. The purpose of this series of trials is to compare
different micronutrient fertiliser strategies in three crops throughout Rwanda:
maize, beans and wheat.
Wolf Trax DDP (Dry Dispersible Powder) Nutrients are micronutrient fertilisers that
feature EvenCoat™ Technology. By coating each granule of the fertiliser blend, DDP
Nutrients can be placed closer to the roots for easier access and earlier availability.
EvenCoat Technology allows dealers to better serve farmer customers by providing
customized ratios of micronutrients to suit individual fields. In addition to improved
field distribution, Wolf Trax DDP Nutrients also feature the patented PlantActiv™
Formulation and are both physically and chemically formulated to resist soil
tie-up for improved plant uptake.
Application of micronutrient fertilisers significantly increased wheat yields relative to the current fertiliser practice.
Yield increases with all micronutrient strategies were comparable, with the exception of Ferticoat which resulted
in significantly higher yields than all other treatments. This could be due to the plant growth stimulant (humic/
fulvic/amino acids/organic stimulants/growth hormones) component of Ferticoat.

RESULTSAcross all sites, micronutrient treatments
significantly increased yield relative to the
‘Current’ fertiliser practice (Figure 1).
Application of Wolf Trax DDPs resulted in
yields that were comparable with granular
and foliar micronutrient strategies, while
application of Ferticoat resulted in significantly
higher yields than all other treatments
(Figure 1).
METHODSThis study was conducted by IFDC at 41 locations with varying soil properties
in three provinces and throughout nine districts in Rwanda. Wheat was
planted and maintained according to regional agronomic practices. The
‘Control’ treatment did not include fertiliser, the ‘Current’ treatment
included 100 kg/ha DAP at planting and a top-dress application of 50 kg/ha
urea, and all micronutrient treatments included 100 kg/ha DAP as well as
200 kg/ha dolomite and 60 kg/ha sulfate of potash applied at planting and
a top-dress application of 100 kg/ha urea. Wolf Trax DDPs and Ferticoat™,
a liquid fertiliser that contains plant growth stimulants derived from humic,
fulvic, amino acids, organic stimulants and growth hormones in addition
to Zn, B and Cu, were applied to evenly coat the granular fertiliser blend.
Granular micronutrients were incorporated into the fertiliser blend and
foliar fertilisers were applied at the appropriate timing (Figure 1).
Treatments that were intended for comparison of liming sources were
omitted for the purposes of this report. The crop was taken to yield and
data was analyzed using general linear models (P≤0.10) and treatment
values were separated using Fisher’s LSD tests.
