A Novel Foliar Color Model for Nitrogen Deficiency Diagnosis of Rubber Trees
AASRI Procedia, 2012 Abstract The foliar color pattern under the stress of nitrogen deficiency varies usually in a uniformly distributed way, so it seems reasonable to fabricate a detection index directly using the averaged value or any of the relative form of its color components.

FOLIAR DIAGNOSIS: THE INFLUENCE OF THE SOIL ON THE ACTION OF FERTILIZERS [PDF]
Plant Physiology, 1939 In an earlier paper (?) reference was made to the fact that no piece of land, however carefully selected for experimental purposes, is absolutely uniform. If the area is divided into equal sections and the sections sub-divided into plots of the same size, the yields from similarly treated duplicate plots planted on the same day with selected ...
