When the compost pile is finished Will produce both visible and non-visible chemical reactions Which is visible is The pieces of the plant will be smaller and more collapsed than when they start to pile up. The color of the scrap will change. The invisible part is the amount of microbes. Here, we will observe whether compost can be used or not. There are simple observations as follows:
1. The color of the compost pile will be darker than when starting the pile May have dark brown to black.
2. The internal temperature of the compost and the outside temperature are very close or different
3. Use a flattened finger. For example, compost looks at waste and will break apart easily. Not hardened
4. Found plants with deep root systems on the compost pile Shows that the compost decomposes well
5. Observe the smell of compost If the compost is available The compost will smell like natural scent.
If there is a pungent odor or a smell of straw, then the compost still cannot be used. Since the degradation process has not been completed
6. Analyze in the laboratory, look at carbon and nitrogen elements if the ratio is equal or lower than 20: 1
Then can be considered as compost
