Hog manure is a valuable organic fertilizer that enriches the soil of crop farmers, helping them grow healthy and nutritious food. Injecting hog manure well below the soil’s surface protects Manitoba’s waterways from run-off. It is one of the best management practices Manitoba hog farmers have adopted to lessen environmental impact.

Manitoba hog farmers regularly invest in research and adopt new and emerging nutrient management methods, technology, and best management practices to further lessen environmental impact.

To learn more about how Manitoba’s 624 hog operations are focused on environmental sustainability, read our Pigs and the Environment factsheet.

 

 

Quote Jorrie

"In Manitoba, the vast majority of pig manure is injected under the soil surface or immediately incorporated. This maximizes the crop's use of manure and ensures that manure will not run off, thereby helping to protect our waterways."

Dr. Don Flaten
Professor, Department of Soil Science, University of Manitoba

Greenhouse gases (GHGs)

About 35% less GHGs are emitted from hog farms now than 50 years ago. Nowadays, GHG emissions from pigs are estimated at just over 4% of the Manitoba’s total emissions. Most livestock-produced GHGs come from ruminants (cattle, sheep and goats), with pigs being a relatively low contributor.

Carbon footprint

It is estimated that in the last 50 years, the total of all natural resources used by pigs has decreased by about 50% per kilogram of pork. For every kilogram of pork produced today, farmers use about 40% less water, 33% less feed and as much as 59% less land.

Manure is a valuable organic fertilizer

Pig manure is a valuable organic fertilizer that has been used by farmers for over 10,000 years to help build and maintain soil health. Using manure as fertilizer is nutrient recycling at its best! By using manure to enrich soil, there is much less need for synthetic, imported or non-renewable fertilizer.

Manure management

Good manure management is essential for minimizing GHG emissions caused by microbial activities during manure decomposition. Every year, farmers file manure management plans with the provincial government (Manitoba Sustainable Development). Following annual soil testing, the manure is applied to farmland based on what nutrients currently exist in the soil, what nutrients are in the manure, and the nutrient requirements of the crop. Manure is only applied at predetermined rates and certain times of the year to prevent runoff.

 
 
 

DID YOU KNOW?

  • Manure – a valuable, organic fertilizer that helps to build and maintain soil health – has been used by farmers for over 10,000 years.
  • By regulation, Manitoba hog farmers must do annual soil tests on fields before applying manure.
  • Farmers must also file annual manure management plans with the provincial government (Manitoba Sustainability Development) and follow these approved plans each year.
  • Manure storages are regularly inspected by government.
  • About 85% of pig manure is injected six inches into the soil or immediately incorporated by professional applicators. Manure stays on the farm field and does not runoff.
  • When manure is used to enrich soil, there is much less need for synthetic, imported or non-renewable fertilizer.
 
 

Manure injection

These days, about 85% of pig manure in Manitoba is injected about 15 centimetres (6 inches) into the soil of cropland. This method of application ensures that valuable nutrients are not lost through runoff into our lakes and waterways but remain firmly in the soil to help crops grow.

Watch the short video on manure injection below.

Manure injection has several advantages:

  • Greatly reduces odour, because the manure is minimally exposed to the air;
  • Reduces greenhouse gases, again because the manure is minimally exposed to the air;
  • Is better for the crops because it gets the manure down to the root zone;
  • Lessens the loss of nutrients, because of minimal handling and exposure to the air; and
  • Almost entirely eliminates runoff: this is very important, since one of the main concerns about manure application is that it might run into waterways.
