TL;DR: An automatic nutrient solution delivery system, developed for plant nutrition research, includes tanks with individual pumps controled by level-switches and a timer, and changes in nutrient content of leaves and roots were observed.
Abstract: This paper describes an automatic nutrient solution delivery system, developed for plant nutrition research. This system includes tanks with individual pumps controled by level-switches and a timer. Mentha crispa cultivated in the automatic sistem produced over three times more as compared to the conventional sistem. Changes in nutrient content of leaves and roots were observed.
