INVESTIGATION OF TRACE ELEMENT SUPPLY OF TOMATO-PLANTS
In our earlier works [1, 2] we gave an account of our experiments on nutrient solutions, they are in chemical respect objective and we carried out them with tomato and red pepper. We found already at that time, that in case of some trace elements the solution-concentration about 1 ppm or more is toxic for plants.
In our new experiments we strove - by means of earlier well proved method - to register the symptoms of deficiency of some trace elements, or to confirm our experiences till now about the toxicity of trace elements.
