The ultimate fertilizer is the same plants you’re growing, but dead.
Sow, but don’t harvest, let everything go. Just once. Let everything come to fruition.
The seeds of the ripe fruits will fall down and spawn again.
As decomposition sets in, the soil gets fed all the nutrients that same cultivar needs to thrive.
Then, next generation, only harvest half of your crops, let the rest fertilize the soil. Living no-til soil is a self sufficient fertilizer machine.
Simply harvest only half of your total yield and let the rest feed the soil. This way you need not do anything else but harvest to the highest of standards, manually, without the need of machines, leaving what is not great to become the best fertilizer for the next generation of itself.
This way the soil is never depleted but only ripens because it can eat a large portion of the fruits of its own labour. More intense and varied flavors can be expected. Better resistance as well. The information about the local weather and soil is stored in the seeds and the DNA has adjusted itself accordingly, to increase chances of survival.
Mother Earth is very clever this way.
Combine with a wide variety of cover crops for best results.
