Magnesium Deficiency In Soil – Causes

In case you didn’t know, magnesium is vital for plant growth. A lack of magnesium can cause plants to become stunted, discolored, and less productive.

Unfortunately, many soils are deficient in this crucial nutrient. Read on to learn more about the causes of magnesium deficiency in soil and how to remedy it.

1. Incorrect Soil Ph

An incorrect pH in the soil can cause a magnesium deficit in plants. Multiple metabolic processes, including photosynthesis and nitrogen fixation, need the presence of the ion magnesium.

Magnesium becomes unavailable to plants when the soil pH is too high or too low, leading to deficiency symptoms.

2. Poor Soil Conditions

Soil health is a significant factor in plant health. When soil is deficient in magnesium, plants cannot take up the nutrient, which can lead to magnesium deficiency.

Magnesium insufficiency can be caused by soil conditions that are not optimal, such as compacted soil or low pH levels.

3. Nutrient Imbalance

A nutrient imbalance is a common cause of magnesium deficiency in the soil. When there is an imbalance, the plant cannot take up the magnesium efficiently, which can lead to a deficiency.

A few things can cause a nutrient imbalance, including over-fertilization, acid rain, and too much salt in the soil.

Also, read below fixes for nutrient imbalance.

How Do You Find Out If The Soil Doesn’t Have Enough Magnesium?

symptoms of deficiency of magnesium in plants

There are various ways to determine whether the soil has enough magnesium. One option is getting a soil test kit from a store that specializes in gardening supplies.

This kit will usually include a testing solution and a color chart. Follow the instructions that come with the kit to use it.

Another way to test for magnesium deficiency is to try the penny test. For this test, you will need a copper penny and white paper.

  • First, place the penny on the paper and then add a drop of water to it.
  • Next, wait for the water to evaporate and then observe the color of the penny.
  • If the penny is orange or brown, this indicates that there is not enough magnesium in the soil.
  • Finally, another way to test for magnesium deficiency is to observe the plants growing in the soil.
  • If the leaves are pale or yellow, this is often an indication that the plant is not getting enough magnesium.

It is required to do magnesium deficiency testing on soil since this micronutrient is critical for the development of plants.

Without sufficient magnesium, plants won’t be able to create chlorophyll, which could lead to their death in the long run.
