That's wrong and obviously so. Established farming practices did not work for 5000 years and then suddenly stop working in the past century. The practices themselves changed. If you want something to search up, there's the increasingly common term "peak fertilizer." > Any replacement for industrial agriculture has to feed 7 billion people without raising prices significantly. Good luck with that. It's 8 billion now. The single most important thing that can be done in that arena is curtail meat consumption. Calories-per-acre are several times higher when the crops are used to feed humans directly rather than the inefficient roundabout of feeding animals then feeding the animals to humans. We will both increase our total food supply and reduce the need for tilling and artificial soil fertilization without having to add a single acre of cropfield. Crops also require much fewer resources (water, electricity, human labor, land area, etc.) to produce and manage than livestock, and do not emit methane.
