Yet during its invention the plow (and its derivatives and therefore the work of the land) has increased agricultural yields ... hence their rapid adoption almost everywhere in the world ... there is Is it not a paradox or is it because today we have so exhausted and killed soils that non-tillage has become interesting again?
In short, here is the article by Sciences et Avenir ...
The interest of "no tillage" confirmed
The 09.10.2016 to 14h00
The compilation of 62 scientific studies comparing agricultural soil tillage practices around the world concludes that there is a definite agronomic advantage of "no tillage". Climate issues should accelerate the abandonment of the plow.

Microbial soil life is the secret of fertile soil. One gram of soil contains a million species of bacteria, 100 000 species of fungi, 1000 species of invertebrates (mites, collembolans, nematodes, etc.) among which the kings of this environment, the earthworms, main actors of soil fertility. Healthy soil has a dozen individuals per m3. This microcosm aerates the soil, breaks down plant residues and transforms them into organic matter again assimilated by plants. It is this recycling that is disturbed by plowing. If the reversal of land has a positive impact on bacterial life by causing the creation of different living environments favoring the multiplication of species, it instead stimulates the appearance of bacteria carrying diseases for plants! In addition, the plow destroys the fragile network of microscopic fungus mycelia that help plants better capture organic matter. Direct seeding in turn lowers bacterial diversity, but it favors species involved in fertility, increases the vitality of fungi and improves their effectiveness in the degradation of organic matter.
