Composting is an ecological process, which turns organic waste into fertilizer for the soil, rich in nutrients. This process is usually divided into several stages, including primary fermentation and secondary fermentation. Secondary fermentation, also known as post-aging stage. This is a vital part of the entire composting process.. At this stage, the organic material undergoes further decomposition and stabilization. Ensure the quality and safety of the final product. Therefore it is necessary, to allow your compost to undergo secondary fermentation.

Firstly, secondary fermentation Helps further break down organic matter. At the stage primary fermentation The most easily decomposed organic matter decomposes. But some complex organic compounds will still remain, which are difficult to decompose, such as lignin and cellulose. They were not fully treated with microorganisms during the first fermentation. Secondary fermentation provides a long period of time and a suitable environment. This allows the microbial community to continue to work on the remaining organic matter, ensuring their complete decomposition. Further decomposition not only improves the quality of the compost, but also makes nutrients more accessible to plants.
Secondly, secondary fermentation promotes compost stability. Compost products may retain some activity after initial fermentation. It means, that its chemical and biological properties have not yet fully stabilized. Thanks to secondary fermentation, the compost product can become more stable. It means, that it does not undergo unnecessary decomposition reactions when applied to soil. This avoids negative effects on plant growth. Besides, stable compost products are less likely to change quality during storage and transportation. This is especially important, if you are engaged in production and sale on a commercial basis.
Finally, in addition to the above, secondary fermentation can also effectively destroy weed seeds and pathogens microorganisms. Improving the safety of the final compost product. At the same time the physical properties of the compost are improved, which makes the compost material finer and more uniform. Facilitates mixing with soil, improves soil aeration and water holding capacity. Secondary fermentation also helps reduce compost odor. Increased comfort during use.
