Why is it recommended to apply manure during autumn tillage, and mineral fertilizers before sowing seeds?

Manure is usually applied to the soil in the fall, even in a warm season, when the crop has already been harvested. At this time, it is actively processed by worms and bacteria. This is how black soil turns out. It is very beneficial for the soil and plants. In addition, one manure fertilization is enough for 3 years. Mineral fertilizers are applied to the soil just before planting. They are not processed, but are already ready for absorption by plants. If you apply fertilizers in the fall, then during the fall and spring, mineral fertilizers will go deeply along with rainwater, which will not improve the quality of plants.
