Do we really need to fertilize our plants?

We all know that plants require air, water and sunlight to grow. As they take root within the soil, the roots not only carry water but also, the essential nutrients used to sustain growth, development and reproduction.

Plants require sixteen different elements:  

These elements include:

  • Carbon  
  • Hydrogen
  • Oxygen
  • Nitrogen
  • Phosphorus
  • Potassium
  • Calcium
  • Magnesium
  • Sulfur
  • Iron
  • Zinc
  • Molybdenum

Of these, the most important and essential nutrients, often considered “primary nutrients” are Nitrogen (N), Phosphorus (P), and Potassium (K). Nitrogen is needed in the formation of chlorophyll, the green pigment in leaves used for photosynthesis.

Although nitrogen is readily available in the atmosphere, plants are unable to utilize it as nitrogen is inert. Therefore, plants need to absorb nitrogen from the soil, in the form of nitrate or ammonium. 

Phosphorus stimulates root growth and flowering, and potassium regulates the uptake of carbon dioxide and water.

Most indoor and outdoor garden soils have a finite supply of nutrients, that deplete over time. Even with the best soil one can find, if the soil is not fertilized and replenished periodically, it becomes less fertile.

When plants grow, they are constantly extracting nutrients from the soil required during flowering and fruiting periods. Indoor house plants grown in pots, do not get exposed to external nutrients in the wild such as rotten wood or animal remains, the soil needs to be fed with fertilizers artificially to restore any lost nutrients over time. Without this necessary step, plant quality and yield will eventually deteriorate.
