Manure vs. Organic Matter

What's the Difference?

Manure and organic matter are both valuable sources of nutrients for plants and soil. However, there are some differences between the two. Manure is a type of organic matter that comes from animal waste, such as cow, horse, or chicken manure. It is rich in nitrogen, phosphorus, and potassium, which are essential for plant growth. On the other hand, organic matter refers to any decomposed plant or animal material, including leaves, grass clippings, and compost. It improves soil structure, enhances water retention, and promotes beneficial microbial activity. While manure is a specific type of organic matter, organic matter can come from various sources and is often used as a soil amendment to enrich the soil with nutrients and improve its overall health.

Further Detail


When it comes to improving soil fertility and promoting healthy plant growth, both manure and organic matter play crucial roles. While manure is a specific type of organic matter derived from animal waste, organic matter encompasses a broader range of materials derived from plants, animals, and other natural sources. In this article, we will explore the attributes of manure and organic matter, highlighting their similarities and differences in terms of nutrient content, soil structure improvement, environmental impact, and overall benefits for sustainable agriculture.

Nutrient Content

Both manure and organic matter are valuable sources of essential nutrients for plants. Manure, being derived from animal waste, contains a rich blend of nitrogen, phosphorus, potassium, and other micronutrients. These nutrients are released slowly over time, providing a steady supply for plant uptake. On the other hand, organic matter includes a wider variety of materials such as compost, crop residues, and green manure. While the nutrient content of organic matter may vary depending on its composition, it generally contributes to the overall fertility of the soil by providing a diverse array of nutrients necessary for plant growth.

Soil Structure Improvement

Both manure and organic matter play a crucial role in improving soil structure. Manure, due to its organic nature, helps enhance soil aggregation, which promotes better water infiltration and reduces erosion. It also aids in the development of soil microorganisms, which contribute to nutrient cycling and overall soil health. Similarly, organic matter, when incorporated into the soil, improves its structure by increasing its water-holding capacity, reducing compaction, and enhancing aeration. This allows plant roots to penetrate deeper, access nutrients, and establish a stronger foundation for growth.

Environmental Impact

Considering the environmental impact, both manure and organic matter offer significant advantages over synthetic fertilizers. Manure, when properly managed, can be a sustainable source of nutrients, as it recycles animal waste and reduces the need for chemical fertilizers. However, if not managed correctly, manure can contribute to water pollution by releasing excess nutrients into water bodies. On the other hand, organic matter, such as compost, helps sequester carbon in the soil, mitigating climate change by reducing greenhouse gas emissions. Additionally, the use of organic matter promotes biodiversity and reduces the risk of chemical runoff, protecting ecosystems and water quality.

Benefits for Sustainable Agriculture

Both manure and organic matter offer numerous benefits for sustainable agriculture practices. Manure, being a byproduct of livestock farming, provides farmers with a cost-effective and readily available source of nutrients. Its use in crop production helps close nutrient cycles, reducing dependence on synthetic fertilizers and minimizing the environmental impact of agriculture. Organic matter, on the other hand, contributes to the long-term health and fertility of the soil. By improving soil structure, organic matter enhances water and nutrient retention, reduces soil erosion, and supports the growth of beneficial soil organisms. These attributes are essential for sustainable farming systems that aim to preserve soil health and productivity for future generations.


In conclusion, both manure and organic matter play vital roles in sustainable agriculture by providing essential nutrients, improving soil structure, and minimizing environmental impact. While manure is a specific type of organic matter derived from animal waste, organic matter encompasses a broader range of materials. Both manure and organic matter contribute to the overall fertility of the soil, enhance water and nutrient retention, and support the growth of beneficial soil organisms. By incorporating these organic materials into agricultural practices, farmers can promote sustainable and environmentally friendly approaches to food production, ensuring the long-term health and productivity of our soils.
