Current farming practices deplete soil carbon, which degrades soil quality, reduces productivity, and results in the need for more fertilization, irrigation, and pesticides. No-till farming with residue mulching would reverse these effects by slowing soil erosion and pollution runoff, benefiting aquatic ecosystems, improving agronomic productivity, and achieving food security. The [authors][1] of this Policy Forum urge support for its wider use. Although there may be short-term yield reductions in some soils and climates, this is a win-win opportunity for the vast majority of the 95% of the cropland that does not use these more sustainable practices.
