Linking a Geographic Information System to Farm Records and Crop Models for Field Management
نویسنده
چکیده
Interpretation of sugarcane field records can bc greatly improved by linking them to a Geographic Information System database, which allows trends to be mapped and queries to be performed. Linking a Geographic Information System to a crop or irrigation model allows simulation of crop yield and irrigation water use efficiency for each field, based on ficld informatton. The Arcview Geographic Information System was linkcd to the IRRICANE crop model, which simulated cane yields for a north coast farm. Observed sugarcane yield and soils data I'or each ficld was used in ArcView to map temporal and spatial trends in production and soil chemical and nutritional status. as well as to dcrivc input data for the IRRICANE model. This paper discusses a method of linking a Geographic Information System to the IRRICANE modcl to establish bcnchmarks for crop performance and cvaluatc irrigation potential.

Agricultural Extension services are among the most important rural services in developing countries. The services are considered to be a key driver of technological change and productivity growth in agriculture. In Kenya, like in the rest of the developing economies, agricultural extension has largely been delivered through supply–driven approaches. Due to perceived low impact of agricultural e...

Cassava (Manihot esculenta Crantz) is currently the most important upland crop of Cambodia, but information on yield variations and causal factors which is important for efficiently targeting efforts to increase production is still lacking. The objectives of this study were to determine the yield variations and causal factors for cassava production in Kampong Cham province in Cambodia. Fort...
متن کاملHarnessing Information Technologies for More Efficient Crop Development
New crops face formidable competition from established crops. Management practices for established crops are well understood, and their productivity gains over time are often spectacular, such as the nearly linear increase in maize yields from 1955 to the present (Troyer 2004). Their long success reflects well-organized research, extension and marketing efforts. For new crops to prosper against...
متن کاملAn Integrated Modelling Approach to Conduct Multi- factorial Analyses on the Impacts of Climate Change on Whole-farm Systems
Climate change impact studies on whole-farm systems require a holistic approach due to the complexities of biophysical processes, management and inter-relationships of land use within a single farm. This paper details the process of utilising a multiple-objective, strategic land use planning tool to conduct multi-factorial analyses on the impacts of climate change at the farm scale. Two example...
