Nutrient content in manures and fertilizers

Nutrient content in manures and fertilizers

In this article, we will learn about the nutrient content found in the different manures and chemical fertilizers. The percentage content of plant nutrients in different organic manures can vary slightly from what has been mentioned below because  the amount of nutrients in organic manures depends on different factors of the material from which the compost/manure is made.
