When it comes to countries with hot and dry climates, we, Kohshin Engineering, often observe the same issue: farmers prefer to dry organic waste or manure instead of composting it. Many believe that dried manure is a beneficial way to nourish their soil. However, experience shows that it has the opposite effect. Instead of enhancing soil health, it reduces crop yields and makes the soil less fertile. Why does this happen? Let’s learn more about the differences between composting and drying methods of manure treatment.
Drying Manure
Dried manure can be harmful to plants because it has a high salt concentration and can lead to nitrogen leaching. When manure dries, moisture evaporates and leaves behind concentrated salts like sodium chloride and potassium chloride. Over time, this buildup of salts causes soil salinity to increase, which can deprive plant roots of water, causing them to dehydrate and become damaged. Additionally, these salts can interfere with the plant’s ability to absorb other nutrients. Although dried manure contains beneficial nutrients initially, it can release nitrogen too quickly when applied to the soil, leading to nitrogen leaching and potential groundwater contamination.
Composting
In contrast, composting is a controlled process where microorganisms break down organic materials, including manure, into stable compost rich in humus. This process stabilizes nitrogen, allowing plants to receive nutrients gradually, thereby minimizing environmental risks. Composting also enhances the water retention capacity of dry soils, making it especially beneficial in regions with low rainfall. This not only promotes healthy plant growth but also helps conserve water resources.
In simple terms, dried manure can harm plants and degrade soil health. Additionally, when manure gets wet, it produces a bad odor that makes surrounding areas unpleasant. On the other hand, composted manure acts as a soil amendment that enhances soil health and fertility while producing a more natural smell when wet.
To support farmers and promote a sustainable environment, we have designed specialized composting equipment that transforms bio-waste into premium, pathogen-free organic fertilizer. We believe that, together, we can make the world a better place by improving soil health and increasing productivity!
