Problems solved by technology

Also, ambient lighting has an effect on leaf color, making phone camera-based methods unreliable
Phone cameras are known to be difficult to identify colors correctly, and accurate color identification requires calibration means, such as a set of paper with predefined colors

Abstract

The present invention relates to a method of determining health of a plant (24), and the method comprises displaying, on a screen (12) of an electronic display of a mobile computing device (10), a digital leaf colour chart (16) with colours ranging from yellow green to dark green; displaying on the screen next to the digital leaf colour chart a white area (20) on which a leaf (22) of the plant (24) is to be placed; receiving the input to the mobile computing device from a user about which colour of the digital leaf colour chart that best matches the leaf placed on the white area; and using the mobile computing device to determine the plant health based on the received input.

Description

technical field [0001] The present invention relates to a method for determining the health status of plants. The invention also relates to computer program products, computer readable storage media, electrical signals and mobile computing devices. Background technique [0002] By recording plant health, especially nitrogen levels, it is possible to know if and when plants need fertilizer in order to improve crop yields. [0003] The Leaf Color Chart (LCC) is a nitrogen management tool used to determine the N fertilizer requirements of rice crops. LCCs are plastic devices that have at least four green bands that vary in color from yellow-green to dark green. Each of the color strips is given a number that increases with increasing greenness. By using LCC to compare the color of representative leaves, the nitrogen status of the crop can be determined. An example of a physical LCC is disclosed in US6734973. [0004] Although LCC has been widely accepted, it also suffers f...
