How can a molybdenum deficiency in plants be prevented? 

Molybdenum (Mo) is an important nutritional element, which contributes to the growth and presence of nitrogen in plants. Without this element, none of the plants would be able to grow. Therefore, it is crucial for a crop to take in enough molybdenum. How exactly can a deficiency or surplus be recognized? And how can it be prevented? In this article, everything is explained by our fertilizer specialist Han van der Kooij.

The importance of molybdenum

The trace element molybdenum plays an important role in the creation of several crucial enzymes. Without molybdenum, the majority of these enzymes would not be functional, resulting in the plants not growing. Besides, this nutritional element is used in the process of the production of plant hormones.

Causes molybdenum deficiency

To ensure a plant’s proper intake of molybdenum, a good drainage, stable pH level and a healthy climate within the greenhouse should be arranged. Several factors for a molybdenum deficiency can be named: 
  • Too low pH level in the soil or substrate
  • Roots aren’t able to take in the molybdenum
  • Excess amount of iron

Results molybdenum deficiency 

Besides the fact that a shortage of molybdenum obstructs the plant’s growth, more problems can arise. It is good to know that a low concentration of molybdenum (<0.06 mg/kg total dissolved solids) can first be seen in the young leafs of the plant. These leafs could start to curl, dry or discolor. When discoloration occurs, the leafs turn purple.

Symptoms molydenum deficiency

The following visual symptoms can be remarked, when a molybdenum deficiency occurs: 
  • Dehydration of the leafs
  • Curling leafs
  • Purple discoloration of the leafs

Prevent or solve a deficiency

In order to prevent a shortage of molybdenum, make sure to have a balanced fertilizing scheme. For this, the pH level should be monitored carefully by means of a pH meter. Molybdenum is often present in soil or substrates with a (too) low pH level. When the pH in the soil or substrate is too low, it can be corrected by adding pH enhancing fertilizers, such as chalk.

Molybdenum surplus

A molybdenum deficiency can cause problems, but so can an surplus of molybdenum. When an excess amount of this element is found in the crop, it could result in a shortage of copper. This because copper and molybdenum are two nutritional elements, that do not go together well. As opposed to a purple discoloration, leafs turning yellow can be a sign of a molybdenum surplus.
