Managing Efficiciency
Nitrogen and Sulphur Use
www.cargill.com
The importance of Nitrogen and Sulphur in Wheat Production
The Role of Nitrogen in Wheat Production
NITROGEN DRIVES WHEAT YIELD
•N promotes new leaf growth
•N promotes tillering of young plants
•N promotes dark green, lush and healthy plants
•N influences grain yield and protein production
•N deficient plants - chlorosis
19
Current Nitrogen Recommendations
WHAT ARE THEY BASED ON?
• The same amount I have always put on!
• Corn example
• Significant advances in production practices
• Genetics / Fungicides / PGRS
20
N amounts for wheat yield
HOW MUCH N SHOULD I APPLY?
•Depends on :• Soil type• Crop Rotation•Manure use• Previous Experience• Fungicide Use- discuss later• Lodging risk• Yield Goal•Maximum Economic Rate of Nitrogen
21
Maximum Economic Rate of Nitrogen (MER-N)
WHAT IS THE BREAK EVEN RATE OF APPLIED N IN WHEAT PRODUCTION?
• Trials completed over 3 years to generate Nitrogen response curves and determine MER-N
22
Wheat Yields with different levels of N
23
Trial Results
NITROGEN PAYS
• 23 Bu gain from 0 N to 60 N
• The same yield increase between 60 N to 90 N as there is between 90N to 120N + 6 Bu
• 2.7 Bu increase from 120 N to 150 N
•Over 60% of sites had MER-N of 150 N of higher
Nitrogen Sources
WHAT IS THE BEST SOURCE OF NITROGEN TO USE ON MY WHEAT CROP?
Nitrogen Sources
• Trials over the last number of years have shown little impact of N source on yield.
• Liquid 28% or 32% have shown a small yield increase (2.5bu/acre)
• ESN has shown no yield advantage in winter wheat but did increase protein.
• Works as part of a Nitrogen blend on hard red wheat when protein adds value
•Agrotain Plus decreased yields when N applications were delayed by weather.
• Used early26
When should I apply Nitrogen in the spring?I WANT TO IMPROVE MY YIELD WHEN SHOULD I APPLY NITROGEN?
• Crop dependent
• Planting Date Late Planting = Early N
• Winter /Tiller survival Poor W/T Survival = Early N
• Green Leaf Area Low GLA = Early N•Weather dependent
• Previous / Current / Expected Adjust to season
• Yield dependent
• Yield Goals High Yield Goal = Early N•Grower dependent
• How many applications of N
• How much total N Adjust to grower situation
Advantages of Splitting N Applications
A LOT MORE POSITIVES THAN JUST YIELD
• Reduced N loss
• Better weed control
•More Uniform Heading
• Lower lodging risk
• Lower disease risk
28
Spring N applications
BEST RECOMMENDATIONS TO DRIVE YIELD
• 1st application in early April GS 30 % Total
80 lbs actual N 66.67%
• 2nd application in late April 2nd Node 33.33%
40 lbs actual N
Total Min N = 120 lbs actual N 100%
High Yield Potential Sites adjust N upwards to 150 lbs per acre and follow % guideline
In HRW save 25 lbs actual N for Flag Leaf Application
2017 N applicationsWHAT TO DO NEXT YEAR?
• 2017 Crop• Early planted/ high leaf growth/ lodging risk/ yield potential
•Management very important
• 1st application @ GS 30 (late March/Early April)•Apply 2/3 total N• 2nd application @ GS 32 (mid to late April) •Apply remainder of total N•Do NOT reduce overall total N Minimum 120lbs
Sulphur Use
SULPHUR THE 4TH MAJOR CROP NUTRIENT
Sulphur Use in Wheat
DO WE THINK ABOUT SULPHUR?
N, P and K = Wheat Production
OR
N, P and K + S = Wheat Production
Reduced atmospheric deposition of s

*Data represents sulfur ion concentration of
precipitation.
Sulphur Use in Wheat
WHY IS SULPHUR IMPORTANT?
• Building block of protein.
• Key ingredient in the formation of chlorophyll.
•Without adequate Sulphur, crops can not possibly reach their full potential in terms of yield or protein content.
• Sulphur promotes efficient use of Nitrogen, Phosphorus and other vital elements.
Sulphur Use in Wheat
NITROGEN AND SULPHUR
• The amount of Sulphur required is closely related to the amount of Nitrogen applied
• Sulphur deficient plants accumulate nitrogen as other compounds, (nitrate, ammonium, amides) therefore the quality of protein is reduced in such plants.
• The ratio of nitrogen to sulphur usually ranges from 10:1 to 7:1
• S improves nitrogen efficiency
•High N Crop = High S Crop
Sulphur ProductsWHAT FERTILIZER PRODUCTS CONTAIN SULPHUR AND HOW MUCH?
•Ammonium Sulfate – 24% Sulphur
• K- Mag – 21% Sulphur
•MESZ – 10% Sulphur
•Gypsum- inorganic Sulphur (calcium sulphate)
•Ammonium Thiosulfate – (Thiosol) 26% Sulphur 2.886 lbs/gal S
•Amidas 5.5 % Sulphur
Sulphur Rates and Yield Responses
Research conducted 2011-2014
Source: OMAFRA
Sulphur Rate
WHAT TO APPLY
• 42 Lbs per acre of AMS
• 3.5 Gallons per acre of ATS
• 180 Lbs per acre of Amidas
= 10 Lbs Sulphur per Acre

Managing Efficiency
Fungicide Use
www.cargill.com
The importance of Nitrogen and Sulphur in Wheat Production
Why do we use Fungicides?
FUNGICIDES RETAIN YIELD
•Disease control
• Foliar Leaf Diseases
• Soil and Root borne diseases
• Retain Grain and Straw Yield
• Green Leaf Area
• Plant Health – Physiological Benefits
• Straw 41
Disease Control
THE LEVEL OF DISEASE DEPENDS ON:
•Variety
• Season
• Crop Rotation
•Weather
•Green Leaf Area
Powdery Mildew in Wheat 25th October 2016
What types of fungicides are available ?
• Fungicide Groups
•Modes of action
• Contact
• Systemic
• Foliar / Soil Applied
Fungicide Trials
• Trial completed in Ontario over a 4 year period

• 28 Varieties trialed in year 4
• Looking at yield Response
Fungicide Trial Results
DO FUNGICIDES INCREASE YIELD?

• 1 year trial or repeated trials over 4 years
• 12% Yield increase from Fungicide Use
• Yield response is variety dependent
• Responsive varieties + 17 bushels per acre
Fungicide Response to Higher N rates
How many fungicides should I apply?
WHAT IS YOUR YIELD GOAL?
• 2 applications as standard

• Leaf
• T2 – Flag Leaf?
• T3 – Application at early flowering GS 61
