True Costs

When considering externalities (health costs, subsidies etc), biodynamic agriculture is competitive with common practice in the short and medium term and even cheaper in the long-term perspective.
Having in mind that biodynamic agriculture matches the yields of more conventional, input-intensive systems, it is apparent that biodynamic agriculture is less expensive than conventional systems that rely on costly chemical inputs and therefore have higher expenses. The reason for this are rising prices for energy and natural resources in general, a trend that will continue to exacerbate in the future.

Another example of why biodynamic agriculture is less expensive than conventional agriculture is the decreased need for irrigation due to an increased water-holding capacity of biodynamic soils.

Further, biodynamic agriculture produces more nutritious food than conventional agriculture because it does not use toxic chemicals for fertilizing or pest control, which in turn will lower health costs for social systems. Healthier soils produce healthier plants, and healthier plants are the basis for a healthy diet for animals. See also Soil.
