![Page 9: Nutrient Master Class for Turf Managers and Greenskeepers](https://reader030.fdocuments.in/reader030/viewer/2022032513/55d1bcffbb61eb16768b4653/html5/thumbnails/9.jpg)
Idea #1: Choose a Better Iron Source
![Page 10: Nutrient Master Class for Turf Managers and Greenskeepers](https://reader030.fdocuments.in/reader030/viewer/2022032513/55d1bcffbb61eb16768b4653/html5/thumbnails/10.jpg)
Role and benefits of iron for grass
• Iron is commonly used as part of turf nutrition packages for its benefits as a greening agent
• Granular prills are the
typical formulation used for application
![Page 11: Nutrient Master Class for Turf Managers and Greenskeepers](https://reader030.fdocuments.in/reader030/viewer/2022032513/55d1bcffbb61eb16768b4653/html5/thumbnails/11.jpg)
Challenges for effective fertilization
Poor distribution - uneven fertilization
• Distribution of typical granular applications can cause unevenness in appearance of turf and grass
• Mobility of micronutrients in soil is limited, meaning some roots get less nutrients than others
![Page 12: Nutrient Master Class for Turf Managers and Greenskeepers](https://reader030.fdocuments.in/reader030/viewer/2022032513/55d1bcffbb61eb16768b4653/html5/thumbnails/12.jpg)
Approaches to fertilizing for greener grass
1) Traditional approach - boosting nitrogen
• Increases growth
• Leads to more mowing
• Increases water usage, turf is more susceptible to disease
2) New approach - using Iron DDP as a fertilizer coating
• Provides green-up without increasing growth
• Requires less mowing
• Does not increase water usage
![Page 13: Nutrient Master Class for Turf Managers and Greenskeepers](https://reader030.fdocuments.in/reader030/viewer/2022032513/55d1bcffbb61eb16768b4653/html5/thumbnails/13.jpg)
Solutions for turf
• Iron DDP offers more even distribution Thoroughly and evenly coats onto granular fertilizer prills, delivering the right amount of micronutrients at many points of contact

Solutions for turf
• More even iron distribution with Iron DDP means: • Greater nutrient availability
• Improved above-ground grass color-up
• Improved below-ground root growth and disease prevention
![Page 15: Nutrient Master Class for Turf Managers and Greenskeepers](https://reader030.fdocuments.in/reader030/viewer/2022032513/55d1bcffbb61eb16768b4653/html5/thumbnails/15.jpg)
Get quicker, longer-lasting green
• Dual Action Availability with Iron DDP
• Multiple forms of active iron guarantees earlier uptake and continuous feeding over time
• Ensures that turf & grass is greener for longer, less need to apply other fertilizers later in the season
![Page 16: Nutrient Master Class for Turf Managers and Greenskeepers](https://reader030.fdocuments.in/reader030/viewer/2022032513/55d1bcffbb61eb16768b4653/html5/thumbnails/16.jpg)
Get quicker, longer-lasting green
Dual Action Availability and 2010 Efficacy Trials • Established stands of turfgrass
were fertilized with Wolf Trax Iron DDP and granular iron
• Chlorophyll content was measured using a SPAD meter and shows that stands treated with Wolf Trax Iron DDP were “greener” than the granular iron

Get quicker, longer-lasting green
Dual Action Availability and 2010 Efficacy Trials • Turfgrass chlorophyll content
was measured at 4 different intervals to determine differences in “greenness”
• Wolf Trax Iron DDP coated onto NPK fertilizer resulted in greener sod compared to the NPK fertilizer alone, especially at the later dates
![Page 18: Nutrient Master Class for Turf Managers and Greenskeepers](https://reader030.fdocuments.in/reader030/viewer/2022032513/55d1bcffbb61eb16768b4653/html5/thumbnails/18.jpg)
Make grass greener • 2010 efficacy trials on turf showed greater plant
uptake of iron and greener grass
• SPAD readings were taken to determine the difference in “green colour” quantitatively
![Page 19: Nutrient Master Class for Turf Managers and Greenskeepers](https://reader030.fdocuments.in/reader030/viewer/2022032513/55d1bcffbb61eb16768b4653/html5/thumbnails/19.jpg)
Make grass greener
Iron DDP treated grass was 6% greener
This was visual to the naked eye.
![Page 20: Nutrient Master Class for Turf Managers and Greenskeepers](https://reader030.fdocuments.in/reader030/viewer/2022032513/55d1bcffbb61eb16768b4653/html5/thumbnails/20.jpg)
Deliver Better Uptake
Wolf Trax Iron DDP was compared to granular iron on grass:
• 50% iron oxide was applied at 1.5 lb/1000 ft2 physical product
• Iron DDP applied at 0.4 lb/1000 ft2 physical product
• Grass was harvested three weeks after treatment, and tissues analyzed for total iron content
• Iron DDP coated on lawn fertilizer showed iron uptake of 109% of check
![Page 21: Nutrient Master Class for Turf Managers and Greenskeepers](https://reader030.fdocuments.in/reader030/viewer/2022032513/55d1bcffbb61eb16768b4653/html5/thumbnails/21.jpg)
Deliver Better Uptake
Despite being applied at a fraction of the rate, the highest concentration of iron was found in the grass plants treated with Iron DDP
![Page 22: Nutrient Master Class for Turf Managers and Greenskeepers](https://reader030.fdocuments.in/reader030/viewer/2022032513/55d1bcffbb61eb16768b4653/html5/thumbnails/22.jpg)
Iron and staining risks
Iron fertilization products tend to stain cement
• Wolf Trax compared the following to evaluate staining:
(A) Iron DDP coated onto granular prills (1% coating)
(B) Granular fertilizer alone
(C) Granular fertilizer blended with iron sulphate
![Page 23: Nutrient Master Class for Turf Managers and Greenskeepers](https://reader030.fdocuments.in/reader030/viewer/2022032513/55d1bcffbb61eb16768b4653/html5/thumbnails/23.jpg)
Iron and staining risks
• Blends were applied to a cement sidewalk, in 1m X 1m blocks adjacent to an urban lawn • The iron treatment was left on the cement for
varying lengths of time and then washed off with water
• Discolouration was rated on a 0 to 3 rating scale where 0=no staining, 3=severe staining

Idea #2: Give your grass seed a better start
![Page 26: Nutrient Master Class for Turf Managers and Greenskeepers](https://reader030.fdocuments.in/reader030/viewer/2022032513/55d1bcffbb61eb16768b4653/html5/thumbnails/26.jpg)
Idea #2 : Give your grass seed a better start.
• Golf courses and turf plots often need to be reseeded to bring area back to optimal appearance and utility
• Can be a lengthy process before seeded and reseeded areas are in desired condition
![Page 27: Nutrient Master Class for Turf Managers and Greenskeepers](https://reader030.fdocuments.in/reader030/viewer/2022032513/55d1bcffbb61eb16768b4653/html5/thumbnails/27.jpg)
Idea #2 : Give your grass seed a better start.
• Seed treatments give grass seedlings the power to grow more quickly
• PROTINUS Seed Nutrition safely delivers key nutrients, vital to early seedling and plant growth
