Profiling the Nitrogen Efficiency Using Agricultural Engineering Technique of YARA ALS Tractor Senso

Nitrogen is one of the macronutrients needed by all type of plants in order for them to grow into a healthy plant. Nitrogen is also one of the important elements in plants because of its role in the chlorophyll production in the leaf. Plants will grow healthy if they receive a sufficient amount of nitrogen needed. The study is conducted at Share Farm UiTM Jasin, Melaka. The YARA ALS N-Sensor has been used to determine the Nitrogen needed by the young oil palm. The result of visual analysis comes in a raster map form the sensor office website. There are 3 types of the map that which are N recommendation Map, N as-applied Map and Relative biomass map. The map is interpreted by the color on the map. For N recommendation map and N as-applied map, the darker the blue color which consists of 16.7% and 5.4% of total area respectively indicates that the area has less N in the leaf while the lighter blue color which consists of 6.0% and 6.7% of total area respectively indicates that the area has sufficient N in the leaf. As for the Relative biomass map, the darker green coloured area which consist 6.9% of the total area indicates that the area has sufficient N while for the lighter colored area which consists of 5.9% of the total area indicates that the area has less N. The area which indicates the less N needs to be applied with N based fertilizer whereas the area with sufficient N did not have to apply fertilizer but needs to be monitored.
