What is composted manure, and how is it different from raw manure?
Composted manure is manure that has undergone the composting process, where it is aged and decomposed by microbes and other organisms. This process not only stabilizes the nutrients in the manure but also kills harmful pathogens and reduces the prevalence of weed seeds. Raw manure, on the other hand, has not undergone this transformation and can potentially contain harmful bacteria and high levels of nitrogen, which may burn plants if applied directly.
The process of composting allows for the beneficial microbes to thrive, enhancing the quality of the manure. Composted manure is often darker, crumbly, and has a more earthy smell compared to raw manure. This makes it not only safer to use but also more beneficial for soil health, leading to improved plant growth when incorporated into gardens.
How can I use composted manure in my garden?
Composted manure can be used in various ways to enhance your garden. The most common method is to mix it into the soil before planting, which helps improve soil structure, water retention, and provides essential nutrients to plants.
