He believes that cover crop mix played a direct role in the 318.5-bushel yield he achieved in 2016. Typically a farmer would have to apply 320 units of nitrogen to achieve those kinds of yields, but Hedrick only applied 140 units, adding that the stalk nitrate samples they pulled after harvest indicated they could’ve gone with as little as 100 units.

In order for carbon to “flow” to soil, there has to be a partnership between plant roots and the soil microbes that will receive that carbon. Somewhere between 85 to 90 percent of the nutrients plants require for healthy growth are acquired via carbon exchange — that is, where plant root exudates provide energy to microbes in order to obtain minerals and trace elements otherwise unavailable

Les solutions mises en avant dans les champs :
"Généraliser les cultures intermédiaires de féverole, de moutarde ou sorgho fourrager entre deux récoltes afin de ne pas laisser la terre à nu. A long terme, il faudrait enfin rompre avec les labours profonds et limiter le nombre des labours superficiels pour en arriver au semis direct. « Il existe quelques exemples de ce type de pratique dans le Lauragais » explique un spécialiste. Mais les gens qui ne labourent plus du tout aujourd’hui ont (…)
Glyphosate : et si on parlait aussi d’autre chose ? - Graines de Mane
Nos débats agricoles sont-ils trop focalisés sur le glyphosate ? Si les controverses perdurent autour de cet herbicide, il est nécessaire d’en décortiquer les usages pour y voir plus clair, dépasser les postures idéologiques afin de se concentrer aussi sur des enjeux bien plus larges.

In the early 1990s, Acton Lake in southwestern Ohio had a muddy problem. Large amounts of sediment from nearby farms were entering the lake’s watershed. These sediments traveled through streams draining the landscape and were filling up the lake.
So, the USDA gave local farmers incentives to change some of their farming practices. One of these practices was conservation tillage, in which the soil is plowed less often. That can reduce sediment runoff.

3 Big Myths about Modern Agriculture - Scientific American
One of the biggest modern myths about agriculture is that organic farming is inherently sustainable. It can be, but it isn’t necessarily. After all, soil erosion from chemical-free tilled fields undermined the Roman Empire and other ancient societies around the world. Other agricultural myths hinder recognizing the potential to restore degraded soils to feed the world using fewer agrochemicals.
