Experiments made with the tissue-test method of assessing the mineral status of plants, using fresh plant material with known deficiencies or grown with known nutrient treatment. showed that there was a fair degree of correlation between visual symptoms. manurial treatment, and the tissue-test data. The tissue-test results invariably agreed with the severity of the deficiency symptoms. The evidence obtained suggests that the tissue-test will prove valuable for diagnostic purposes, though further work is necessary to solve certain problems.
