Just like humans, there are micronutrients for plants. These micro-nutrient supplements create a more well-rounded, healthy plant. Macronutrients such as nitrogen, phosphorous, and potassium are essential, but it is important to ensure proper secondary nutrition as well.

What are the most important micronutrients for plants?

There are 10 micronutrients for plants that you should be aware of, but there are tons more that may not get as much recognition. Here are the most important ones:

  • Boron
  • Chlorine
  • Copper
  • Cobalt
  • Sodium
  • Silicon
  • Iron
  • Manganese
  • Molybdenum
  • Zinc

Why your plants need a micronutrient supplement

Some soils will contain an adequate supply of these important nutrients, but many are inadequate, such as sandy or low-organic-matter soils, and high pH soils. Plants grown hydroponically will also lack sufficient micro-nutrients.

What are signs your plants are deficient in micronutrients?

There are some tell-tale signs that your plants may be deficient in certain micronutrients, but from there, you still need to accurately diagnose which specific micronutrient is responsible. We have an entire article on diagnosing nutrient deficiencies, but here are some common symptoms:

  • Chlorosis
  • Deformed leaves and discoloration
  • Stunted growth, reduced internode length
  • Wilting of leaves
  • Loss of turgor

Soil Meters & Test Kits help you be sure your plants are actually deficient in micro-nutrients. But by being aware of what type of soil you are growing in, you can prevent any issues from arising in the first place by supplementing with some of our micronutrient products from the start.
