Adoption of CA at the farm level is associated with lower labour and farm-power inputs, more stable yields and improved soil nutrient exchange capacity. Crop production profitability under CA tends to increase over time relative to conventional agriculture. Other benefits attributed to CA at the watershed level relate to more regular surface hydrology and reduced sediment loads in surface water. At the global level, CA sequesters carbon, thereby decreasing CO2 in the atmosphere and helping to dampen climate change. It also conserves soil and terrestrial biodiversity.
