In nature, it takes a very, very long time for plant and animal matter to break down into rich, fertile topsoil. However, if your compost heap is curiously slow and inactive, or has been forgotten and neglected for a long time, there are ways to stir it up and kick it into humus-making activity.
You can use these 6 Compost Activators to Fire Up Your Compost Pile:
1. Grass Clippings
Adding recently cut grass to a compost pile can quickly transform a stagnant heap into a chaotic mess.
The N-P-K ratio of freshly cut grass is 4-1-2. Grass clippings should be added to the compost bin as soon as possible after mowing the lawn since the nitrogen they contain is lost as they dry.
The mound of freshly cut grass quickly decomposes. However, when it decomposes, grass uses up a lot of oxygen, which is good for the bacteria and the temperature. Grass clippings not only clump together and stink up the whole compost pile, but they also produce anaerobic conditions.
Mixing grass clippings with brown materials thoroughly before adding it to the pile is an easy way to prevent this from happening. A ratio of two parts carbon to one part grass clippings is ideal.
After the first 24 hours, turn the grass in the compost. In the coming days, keep turning it frequently to avoid clumping of the grass. The clippings will stay more evenly dispersed in the pile if you aerate it on a regular basis.
