Agriculture conservation role of moisture and soil organic matter semi-arid

The uncertainty in rainfall semi-arid regions and their need for annual water negatively affects production and grain yield. These characteristics are obstacle rapid changes in the varieties range or cropping systems to cope with climate changes. Soil loss is very advanced by different erosion. These phenomena are exacerbated by production systems (monoculture cereal and fallow) and methods and tools used tillage (plowing and recrossing). The wait for rains to begin initial work of soil is necessary. This leads them to significantly reduce period of crop growth, already reduced in recent years because of climate change, including drought and global warming. The performance impacts direct seeding techniquesʹ are discussed in turn, through the tests conducted in the region results. We will proceed to soil parameters study such as moisture and organic matter and crop yield parameters (wheat grain yield). Simplified work studies on cereal crops are beginning to draw tracks and paths for more research to understand why not to integrate this system on the farm friendly vis-a-vis natural resources.
