Spread Of Conservation Agriculture Youtube Stress factors. degradation of agricultural land and ecosystem services must be avoided by all means. agricultural land degraded by past abuse must be rehabilitated [2]. the alternative no till system paradigm known as conservation agriculture (ca) can meet all these objectives [2,4,7–10]. ca save on energy and mineral nitrogen use in. Conservation agriculture (ca) has been practised for three decades and has spread widely. we estimate that there are now some 106 million ha of arable and permanent crops grown without tillage in. As t able 2 shows some 66.4 m ha (42%) of the total global. area under ca is in south america, corresponding to some 60. % of the cropland in the region, and some 54 m ha (34%) is. in the usa and. 1.2 deinition and description of conservation agriculture. according to fao, conservation agriculture (ca) is an approach to managing agro ecosystems for improved and. sustained productivity, increased proits and food security. while preserving and enhancing the resource base and the environment.
