Agriculture is Net-Zero

—Farmers in Canada store

33Mt /yr more CO2e than we emit

The Fertilizer 4Rs

— Current factors in the NIR that estimate

fertilizer N2O emissions:

• Provincial N fertilizer sales (Rate)
• Precipitation, evapotranspiration and

topography

• Soil texture

— So the dollars we spend to adopt 4R practices and use enhanced

efficiency fertilizers each year will not reduce our GHG emissions reported in the NIR unless we buy less, which is the Rate R

Carbon Contained in Fertilizers

— Short term carbon passed between

sectors is storage in the industry sector and emission in the Ag Sector as CO2

— This is a good approach since not all

fertilizer is made in Canada or used in Canada

— Carbon in grain is no different

Carbon Contained in Fertilizers

— Ammonia Production (haber bosch) first

step in capturing nitrogen from the air to produce Urea

— 4.5.2. Methodological Issues, 2019 NIR p101:

“The Ammonia Production category estimates CO2 emissions resulting from the feedstock use

• f natural gas and considers emissions that are

recovered for use in urea production.”

Carbon Contained in Fertilizers

— 4.5.2. Methodological Issues, 2019 NIR p101:

Ratio of Urea C density vs CO2 Emission reduction from CO2 stored in urea Urea production

Fraser McPhee

@FarmerFrase

NIR - NH3 vs Urea In the Soil

— “Carbon dioxide emissions from liming,

urea application and other carbon- containing fertilizers are calculated based

• n the total quantity of C contained in

these products.”

2019 NIR – Part 2, page 233

— Anhydrous Ammonia (NH3)

0% Carbon

— Urea (CH4N2O)

20% Carbon

Canada’s NIR - LULUCF

2019 NIR – Part 1, page 7, table ES-2

— Practices that we adopt on our farms to

capture more carbon in our soil, will not be recognized in Canada’s national emission totals
