Abstract
The concept of precision farming, especially in fertilizer, aims to make fertilizer effective and efficient. In this study liquid applicator and fertilizer used were used, namely Urea and KCl. The applicator was tested in the field with a land size of 36 x 8 m divided into 6 plots and a spacing of 40 x 20 cm. Recommendations for fertilizer application are based on laboratory tests of Nitrogen and Potassium content each plot. The parameters recorded are the time and volume of the fertilizer used. From these data obtained the value of effective field capacity, theoretical field capacity, field efficiency and coefficient of variance. From the analysis results obtained field efficiency values of 78.4% and CV values for each plot ranged from 5.21 - 12.22%
