Abstract
New Britain Palm Oil Limited NBPOL uses Geographical Information System GIS as a tool to spatially display research data in addition to detailed plantation mapping. This paper describes the method in which spatial analysis is done using data from a long term Agronomy trial. Using GIS the trial block with each individual palm was created and linked to a database containing all the recorded data and thematic maps created. The experiment carried out at Haella is a 2 hectare fertilizer omission trial running over 5 years 2003-2008. It was established to test the theory that nutrient movement was occurring downhill through the subsoils. The trial was located at a bottom of a slope with a large area of fertilized palms on the slopes above it. According to the theory if nutrients were moving down slope palms facing upslope would suffer the least from lack of nutrients and this deficiency would increase moving down slope into the trial site. Results from spatial analysis done on the yield and foliar data showed elevated leaflet N and leaflet P concentrations towards the top half of the plot indicating possible movement of N and P down slope. However this did not translate to a clear response to yield across the trial site. This trial is continuing.
