Most common fertilizers contain nitrogen, phosphorus and potassium. Nitrogen is the issue. Surpluses of nitrogen in the atmosphere can produce pollutants such as ammonia and ozone. Too much nitrogen will contaminate soils and waterways and, of course, harm our health. Policymakers have every right to be concerned.
But the federal government wants an absolute reduction in emissions, regardless of productivity or efficiency of fertilizer use. For many crops, Canadian farmers’ ability to grow anything will be severely compromised unless they use more land.
It’s unclear how food prices would be impacted but producing food on a large scale would likely become much less cost-effective.
Aggressive emissions targets will likely lead to more famine worldwide. And, since we trade with the rest of the world, mainly with the United States, our crops would likely become less competitive.
With lower supplies, input costs for food manufacturers and grocers would likely increase significantly, pushing food prices higher. This is one aspect of the emission reduction issue in farming.
The needs regarding food production vary widely from region to region and between crops. Supply-managed commodities like dairy, eggs and poultry will be spared, receiving more for their products no matter what. Most of these commodities are produced in Ontario and Quebec.
