• What are the symptoms of phosphorus deficiency in plants?

Starting off with the name of this nutrient, since two names are used; phosphorus and phosphate. According to our fertilizer specialist, it closely depends on the context in which the nutrient is discussed. ‘’One speaks about phosphorus concentrations in the surface water and about the phosphorus concentration in a plant. In natural environments, phosphorus can be found mostly in phosphate connections. These connections are formed by phosphate and oxygen (e.g. H2PO4 and P2O5). The term phosphate is generally used in terms of soil science, fertilizing consultation and fertilization policies. Briefly, the term phosphate is used when the nutrient has not been taken in by the plant yet. After the nutrient is absorbed by the plant, the words phosphate is used.”

The presence of phosphorus is essential for every plant, because of its important function. Not only it is needed for the plant’s development, but also for processes such as photosynthesis and assimilation (‘breathing’). Also, the transportation of energy within the plant cells is arranged thanks to phosphorus. The macro nutrient can be seen as a building block of cell walls, DNA and many different types of proteins, enzymes and other types of organic material that can be found in the plant. And this is of high importance for a plant’s growth.

A shortage of phosphorus can be caused by many different factors, such as: 

• The pH level in the soil or substrate being too low
• The soil or substrate being (too) dense, complicating and obstructing the intake of phosphorus
• The concentration of iron in the soil or substrate being too high, causing problems in terms of the intake of phosphorus
• Not stopping the availability of phosphate during the blueing of hydrangeas
  

When looking for a shortage of phosphate, close attention to the leafs and roots of the plant should be paid. Both leaf and root damage and a brake in overall growth could be caused due to a low concentration of phosphorus.

A plant shows various symptoms when phosphorus deficiency occurs, including:

• Red/purple or matte leafs
• Dying or curling leafs
• Slower growth or a delay in the development of young roots

Logically, it is considered very important to find out how the phosphorus deficiency in plants is caused. Several factors should be kept in mind for an optimal fertilization. First of all, a healthy soil life ensures an easier intake of nutritional elements. Also, take into account, the pH level in the soil or substrate should be monitored regularly. This can be done by means of a pH meter. If incorrect values in relation to the pH value appear, be warned to add fertilizers with acidifying or base effect in order to adjust the pH value the right way.

As opposed to a shortage of phosphorus, the slight possibility for a phosphorus surplus should be remembered as well. In practice, a surplus of phosphorus is unlikely to appear. However, it should be prevented at all times, because it will negatively affect the intake of other important nutritional elements. If a phosphorus surplus occurs, it is likely to appear in combination with a zinc, copper and/or magnesium deficiency. It makes sense that the concentration of these nutrients within the plant will stay behind, when the intake is obstructed by a high concentration of phosphorus.

How can an iron deficiency in plants be prevented?
The micro nutrient iron (Fe) is essential for every plant. Iron is used in the process of photosynthesis and is needed for the root’s growth points.

How can a boron deficiency in plants be prevented?
Boron (B) contributes to several processes of metabolism. Thereby, it’s the only trace element for which an exact dosage is crucial to the plant. 

How to establish a nutritional feeding schedule?
In order to establish a nutritional feeding schedule that ensures optimal results, it has to be carefully aligned with the nutritional needs of your crop.
