ABSTRACT: The key of precision
farming is the right decision in terms of time, quality, quantity, and specific
location in the farming activities. Soil electrical conductivity (EC) is a
variable that is both practical and efficient to implement precision farming.
Several methods of EC measurement for precision farming have been developed and
applied in precision farming, but inaccuracy on the interpretation of
measurement result frequently encountered due to complexity of soil conditions
and various geospatial condition. This paper presents a study on EC
interpretation by focusing on interaction between moisture content, soil
density, and soil N, P, K ratio which affect soil EC measurement. Soil samples
of various levels of water, compaction, and N, P, K ratio are measured using a
soil box resistivity. The levels of moisture contents were devided into low
moisture content that have moisture content less then 20% and high moisture
content that have moisture content more than 20%, while the levels of soil
compaction were devided into high density condition and low density condition.
Regression equations for N, P, and K ratio prediction have been generated and
the coefficient of determination (R2) were obtained ranging between 0.6 and
0.89 for low moisture content and
