Mechanization is a fundamental input in sustainable agriculture. The global scaling-up of Conservation Agriculture (CA) has been followed by the development of new machinery designs, for different field and crop conditions, with participation of farmers, industries, researchers and other stakeholders. This chapter offers an account of the technological developments in CA machinery from the experiences of important actors operating on different continents. The chapter examines the needs of CA in terms of mechanization inputs, describes the machinery used under smallholder and large-scale agricultural systems across four continents, and a presents a vision of how the mechanization of CA could evolve in the near future. |

Pastures are of central importance in food production and provide multiple ecosystem
services. The objective of this paper was to determine whether the intensification of pasture-based
animal production systems, through practices such as fertilization and improved pasture species, has
a higher capacity in the short-term (five years) to sequester carbon in the soil compared to (1) natural
grassland without anthropogenic interactions, (2) natural grassland fertilized and overseeded with
exotic species, and (3) annual pastures with frequent soil disturbance. The study assessed the organic
carbon stock (OCS), total organic carbon (TOC), particle size, porosity, and density at different soil
strata, as well as the root system and forage production. Forage dry matter (DM) production varied
significantly with means ranging from 6615 to 13,000 kg ha?1 year?1 for natural grassland (NG)
and permanent pasture (PP), respectively. Improved natural grassland (ING) and NG presented a
higher density and root diameter than PP and annual pasture (AP). Forage systems significantly
influenced soil porosity and density, with NG and ING showing lower soil densities and higher
soil porosities. The OCS (0?100 cm) was similar between NG (270 Mg ha?1), ING (255 Mg ha?1),
PP (274 Mg ha?1), and AP systems (256 Mg ha?1). Over a period of five years, the intensification of
pasture-based animal production systems did not have a significant impact on OCS in the soils of a
Brazilian subtropical highland. |
