Study Notes

Macronutrients Required by Plants

Macronutrients are essential elements needed in large quantities for plant growth and development.
Primary macronutrients include nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur.
An element that is not considered a macronutrient must be specified; typically, micronutrients or non-essential trace elements fit this description.

Micronutrients Required by Plants

Micronutrients are crucial for plants but are required in smaller amounts compared to macronutrients.
Examples include iron, manganese, zinc, copper, molybdenum, and boron.
An element not categorized as a micronutrient is also needed to be identified.

Justus von Liebig’s Law of the Minimum

This law posits that plant growth is limited by the nutrient that is in the shortest supply, regardless of the presence of other nutrients.
If an essential nutrient is lacking, it can lead to poor growth and development, as plants cannot compensate for deficiencies.

Nutrients Absorbed by Plants from the Air

Essential elements obtained from the air include carbon dioxide and oxygen.
Plants utilize carbon dioxide during photosynthesis to produce energy.

Nutrients Typically Obtained from Soil

Essential nutrients such as nitrogen, phosphorus, potassium, calcium, magnesium, and trace elements are absorbed from the soil.
Soil quality and composition significantly influence the availability of these nutrients to plants.
