A Novel Foliar Color Model for Nitrogen Deficiency Diagnosis of Rubber Trees
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]
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 ...

FOLIAR DIAGNOSIS: PRINCIPLES AND PRACTICE [PDF]
As a result of the broader view now taken with respect to the problems of soil fertility it is recognized that the conditions required for maximum growth must be sought from the facts of plant physiology as well as from those of soil science. For satisfactory growth a particular soil must satisfy certain conditions with respect to temperature, and to ...
