The dryland areas of Central Chile are associated to Mediterranean climate. Under these conditions, water availability during crop growth is a crucial factor for crop productivity. Conservation tillage systems play an important role in this area, increasing soil water availability; however, crop yield responses can be variable. Soil management should be aimed at reducing water loss and promotin...

The main objective of CRP 1.1 Dryland Systems is to achieve sustainable agricultural development in the drylands. On the technical level, it will aim at reducing demand for water per unit crop area, improving water capture and storage, increasing productivity per unit of water at farm and landscape levels, and changing land-use practices to better manage risk and sustainably enhance production ...

soil organic matters are considered as the animal and plant residues and active components of soils. the cultivation practices will cause the quick removal of organic matters in soils even in those which are not affected by erosion. this study was carried out to assess the level of soil humus in the pilot area, to investigate the positive or negative effect of humus level on soil and to introdu...

Abstract Due to global warming, the lengths of four seasons, which are always taken as constant values, have experienced significant variations with rising temperature. Such changes play different roles on regional climate change, most effect drylands. To guarantee local crop yields and preserve ecosystems, identification seasons in drylands is important. Our results show that, relative humid l...

Abstract Precipitation is crucial for life and the ecological environment in Asian drylands. This study investigated precipitation trends drylands previous four decades simulated its possible linkage with snow cover reduction over Tibetan Plateau. The results show that has been increasing contributing to wetter conditions can be attributed deepened quasi-stationary wave trough around Lake Balkh...
