Grass, like crops, needs certain mineral nutrients to grow well, but you don’t really see people fertilize grass. In winter, the grass is burned into ash, and the mineral components are retained in the ash. The ash can seep into the soil with the rain. In this way, the minerals return to the soil, just like applying fertilizer.

This is also the reason why people feel the air is particularly fresh on the lawn; It also reduces noise.
