Question

Place the following in the correct order (from first to last) for preferential uptake of nutrients:

a) Potassium
b) Phosphorus
c) Nitrogen
d) Magnesium

Answer 1

The preferential uptake of nutrients from soil by plants follows the order: Nitrogen, Phosphorus, Potassium, and Magnesium.

Step-by-step explanation:

The correct order of preferential uptake of nutrients is: c) Nitrogen, b) Phosphorus, a) Potassium, and d) Magnesium.

Plants obtain the macronutrients nitrogen, phosphorus, and potassium, as well as the secondary macronutrients calcium and magnesium, from the soil. Nitrogen is needed for leaf growth, phosphorus is important for root development and flower/fruit production, and potassium promotes stem growth, water movement, and flowering/fruiting. Magnesium is not considered a macronutrient, but it plays several vital roles in plants, such as being a part of the chlorophyll molecule.
