The stress of grasshoppers negatively affects the fertile layer of the Earth. Jewish biologists have found an interesting pattern. It turned out that the fertility of the soil depends on the feelings of the grasshoppers. This is not a joke: the calmer their state of mind, the better it affects the soil. If the "green ones" are stressed or worried about something, then the fertility of the land becomes worse, and this is followed by a lower yield of crops grown on it.
And the point is in the level of nitrogen that is in the body of these insects. The amount of stress affects the amount of nitrogen in their bodies. After death, stressed grasshoppers can give less nitrogen to the soil, and much more than cheerful and calm individuals. The first case negatively affects the decomposition processes, and also changes the composition of soil microbes.
The experiment involved two groups of insects. Some lived dangerously close to spiders, while others did not experience any stressful sensations. The nitrogen assumption was fully confirmed.
