Perspectives of Precision Agriculture in Conservation Agriculture

摘要: Conservation practices have clearly shown advantages in improving soil, water and air quality as well reducing costs of operations. natural resources is the base for a long-term sustainability agricultural ecosystems. Agriculture not just conservation tillage, but series land management that include crop residues retention, cover crops, appropriate cropping system rotation, integrated pest able to minimize degradation. Because complexity associated with ecosystems, practice found be sustainable at one site might equally another site. Agricultural production systems are inherently variable due spatial variation soil properties, topography, climate. To achieve ultimate goal systems, variability must considered both space time because factors influencing yield different temporal behavior. Advances technologies such Global Positioning Systems (GPS), Geographic Information (GIS), remote sensing simulation modeling created possibility assess present field manage it site-specific practices. Such approach commonly called Precision or management. The objective this paper evaluate potential use principles technology Agriculture. Examples application through integration various techniques presented show benefits resources. Further perspectives also discussed link mosaic agriculture.
