Why is compost a bad idea?

While everyone praises the merits of compost, Fanny Agostini explains that he also has weak points. If you are lucky enough to have land, put your organic waste directly on the ground, you will feed it four times better.

Fanny Agostini ends the week by telling us that composting is a waste. Isn't composting a good idea?

To understand where Fanny Agostini is coming from, you must first know the basics of how the soil works. When a plant grows, its purpose in life is to reproduce and therefore to mature and to make seeds. Then it will die and decompose on the ground. The stems or leaves will serve as food for a small world, the fungi, insects and earthworms which will digest this material and create humus which itself will be eaten by bacteria which will ultimately produce mineral elements: This is a complete loop of living soil, with a multitude of stages well established for at least two billion years and it is this constant recycling of plant debris that will guarantee permanent fertility at the exit .

Now, when we make compost are we going to short-circuit a stage?

This is a bit of a bug in our desire to do well with compost, we grill a step. To make a compost is to lose a lot of energy which is not used to feed the cycle. For example, on a kilo of your food remains that you put in the compost, there will be fermentation and reduction in mass, in the end in a few months, you will only have a few hundred grams. Some will have evaporated, producing CO2 and methane in the process. This energy is wasted because it will not enter the cycle.

By putting compost on the ground, do we feed the bacteria directly?

We short-circuit part of the food chain, the fertility of the soil will be temporarily boosted while optimizing it, we must imitate nature and allow a maximum of fresh vegetation to self-degrade on the spot. This is how we can keep soils full of life. If you are lucky enough to have land, put your organic waste directly on the ground, you will feed it four times better. Finally, if you live in the city, it is better to compost this waste rather than putting it in the trash.
