The amount of trace elements per kg dry matter is: (a) 10 m mole (b) above 10 m mole (c) below than 10 m mole (d) 100 m mole
Option C.Macronutrients: Elements that are required in amounts greater than10 mmole per kg of their dry weight are grouped under macronutrients. Example- Carbon, hydrogen. ii. Micronutrients: Elements that are required in amount less than 10 mmole per kg of their dry weight are grouped under micronutrients. These elements are also called trace elements. Example- Iron, copper.
