- Fertilizer requirement mapping is the way of determining fertilizer demanded by specific crop production type on the basis of soil sample testing results. It is very important method for modern precise agriculture to increase fertilizer use efficiency and environmental friendly. Hence, in order to make efficient fertilizer application for maize at Shashamane district, the study tried to map phosphorous requirement for maize (Bako Hybrid - 660). Starting form soil sample collection, laboratory analysis and interpretation and mapping standard methods and tools were used. The total soil samples used for the maize potential villages were 147 and Phosphorous critical for maize was 35 ppm and Phosphorous factor was 1.14. Based on these phosphorous requirement was calculated by subtracting initial soil phosphorous from Phosphorous Critical for maize at the study area. Then the map of phosphorous requirement in ppm was predicted for the whole unknown locations by using ordinary Kriging interpolation of ArcGIS10.1 software. The output ranges from 12.5 to 32.5ppm for the whole area with an average of 22.66ppm. Therefore in order to apply phosphorous fertilizer at Shashamane district for maze very efficient rate is just using the map, otherwise using the mean rate (22.66ppm) can also be suitable than blanket application rate. The farmers, Development agents, researchers and other stakeholders can use the output directly or by validating with additional sample results.
