Carbon Farming
Improved annual cropping systems include the following practices: crop rotations, green manures, and cover crops; mulching, reduced bare fallows, and reduced tillage; the System of Rice Intensification (Fig. 2) and improved rice paddy management; nutrient management; and organic production. These can sequester low but significant amounts of carbon, typically 2 tons per hectare per year or less (Seeberg-Elverfeldt and Tapio-Bistrom 2012). Organic systems range from 0.7-2.3 t/ha/yr (Seebert-Elverfeldt and Tapio-Bistrom 2012; Hepperly et al. 2009). Conservation agriculture is estimated to sequester 0.1-1 t/ha/yr (Lal 2014). Improved annual cropping systems have many advantages: they allow us to keep the crops we know and love; they don’t require big changes in production, harvesting, or processing machinery; and they can be implemented at a wide scale on the world’s vast annual croplands.

- Deep litter systems are living systems in which a thick layer of carbon-rich organic matter hosts a thriving microbial community which works to break down solid and liquid wastes from animals as they are produced. Such as system doesn't require regular cleaning out, and has the added benefit of...
