Carbon-Nitrogen Ratio: Understanding Chemical Elements in Organic Matter

Adding compost or other nutrients can help you find the right carbon-nitrogen ratios.

Carbon-nitrogen ratios are an important part of understanding soil, as explained by Crow Miller in this piece earlier published in Acres USA magazine:

There are two chemical elements in organic matter that are extremely important, especially in their relation or proportion to each other: they are carbon and nitrogen. This relationship is called the carbon-nitrogen ratio. To understand what this relationship is, suppose a certain batch of organic matter is made up of 40 percent carbon and 2 percent nitrogen. Dividing 40 by 2, one gets 20. The carbon-nitrogen ratio of this material is then 20 to 1, which means 20 times as much carbon as nitrogen. Suppose another specimen has 35 percent carbon and 5 percent nitrogen. The carbon-nitrogen ratio of this material then would be 7 to 1. Anyone who handles organic matter, who mulches, or who composts, regardless of which method is used, should have some idea about the significance of the carbon-nitrogen ratio.

Acres U.S.A. Podcast Episode 1: Abbey Smith and Charles Walters

Abbey Smith, global network coordinator for the Savory Institute.

Abbey Smith, global network coordinator for the Savory Institute.

 

In Episode 1, we interview Abbey Smith with the Savory Institute and ask her about her life as a teacher, rancher and world traveler. She’s spent years studying and practicing holistic grazing methods, and is trying to help the Savory Institute reach their goals of creating and protecting 1 billion hectares of sustainable grazing land around the world.

Then, we turn back the clock and present a talk from Acres U.S.A. founder Charles Walters. He details the challenges facing eco-farmers, which is still applicable today, and how those challenges increase in the face of the popularity of conventional farming.
