Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The amount of macronutrients per kg of dry matter is-
A
10 mmole
B
Above 10 mmole
C
Less than 10 mmole
D
0.1 mg
Explanation: 

Detailed explanation-1: -Mineral elements, which are required more than 10 millimole per kg of dry matter are classified as macronutrients. The mineral elements required in amount less than 10 millimole per kg of dry matter are classified as micronutrients. Was this answer helpful?

Detailed explanation-2: -The concentration of macro nutrients in dry matter is excess of 10mmole per kg.

Detailed explanation-3: -Micronutrients or trace elements are those essential elements which are required by plants in small amounts, less than 10 mmol/kg of dry matter. Hence the concentration when it exceeds 10 mmol/Kg of dry matter in plants may result in toxicity.

Detailed explanation-4: -Solution: Micronutrients or trace elements, are needed in very small amounts (less than 10 mmole Kg-1 of dry matter). These include iron, manganese, copper, molybdenum, zinc, boron, chlorine and nickel.

Detailed explanation-5: -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.
