SYSTEM FOR DETERMINING N-P-K CONCENTRATION AND RATIO IN SOIL

摘要

The present utility model relates to a system for determining N-P-K concentration and ratio in soil. Particularly, the utility model pertains to a system for determining N-P-K concentration and ratio in soil, comprising N, P, and K test solutions, wherein the test solutions change color and tint based on the N, P, and K concentration and a portable device further comprising a color sensor for capturing color and tint of the test solutions, a processing device for determining N, P, and K concentration based on the captured color and tint data, and a display device for displaying the determined N-P-K concentration and N-P-K ratio.
