NPK for Plants

NPK for plants – nitrogen, phosphorus and potassium. You will find these 3 macronutrients in almost every fertiliser, and for good reasons. These together with magnesium and calcium are the nutrients that plants need in the greatest amounts. In this article, we will take a closer look at the different nutrients plants need and why. This article will discuss the following:

NPK for plants: macro and micronutrients

Nitrogen (N), Phosphorus (P), and Potassium (K) are all classified as macronutrients. What this means is that crops require relatively more of these nutrients than other nutrients. The nutrients that are essential for plants to survive but are required less in terms of quantity are referred to as micronutrients. Even though plants require less of these micronutrients they are still essential to plants’ survival. When growing in soil, especially soil that is rich in nutrients, using a fertiliser which only contains macronutrients might be enough as micronutrients might already be naturally present in the soil. Doing a soil test is recommended to know more precisely what nutrients should be added to the soil. When growing hydroponically or in other growing mediums it is especially important to choose a high-quality fertiliser which also contains micronutrients and trace elements. When plants are deprived of necessary nutrients they are more vulnerable to diseases, poor growth, bad yields and might die. 

NPK for plants: importance and use

When using a fertiliser NPK for plants the label of the fertiliser will tell you the amount of Nitrogen, Phosphorus and Potassium the fertiliser contains. This will look something like 10-10-10, or 10-0-20 and so forth. The higher the number the higher the concentration of the nutrient. How much you need to feed and how often will depend on many variables, such as the soil quality and the type of crop you are growing. Performing a soil test before making your feeding schedule is always recommended. The different nutrients are important for different reasons:

  • Nitrogen: is essential to the photosynthesis process and for healthy plant growth. Nitrogen deficiency can look like slow growth and reduced yields.
  • Phosphorus: is important for your plants’ overall health and growth. A phosphorus deficiency can be detected by stunted growth and a darkening of the leaves.
  • Potassium: can have an influence on plant growth, shape and even on the taste of fruits and vegetables. A lack of potassium can cause problems with the health and strength of the roots.
