Kalmet, R. (Estonian Agricultural Univ., Tartu (Estonia))
Visual pathological symptoms, caused by either abundance, absence or incorrect proportion of plant mineral elements in subtratum, can be found in case of intensified effect of these factors. Pathological symptoms can reflect the absence of a particular nutritional element, but in most cases the symptoms are atypical in character, predominantly in the form of either chlorosis or a necrosis refelecting the absence of combined nutrients. Chemical analysis of a plant in earlier stage of growth can either reveal the potential nutrient supply of the plant, or the latent deficiency of it. Furthermore, analysis of the soil can provide essential information of the mineral contents of the planned place of growth
