The importance of boron and molybdenum - Agran Liquid Technology

Micronutrients play an essential role in plant nutrition. Although their application is quite small in terms of volume compared to other nutrients (nitrogen, phosphorus or potassium, for example), their deficiency causes equally significant production losses. In this article we analyze the importance of boron and molybdenum in agriculture. Although these 2 microelements have always been attributed an important value in flowering and pollination, their role goes far beyond this phenological phase.

The importance of boron in plant nutrition

Boron is practically one of the most important microelements for plants. It is related to the construction of the cell wall and the management of photoassimilates (sugars and carbohydrates) produced by the crop.

Its application is also associated with calcium treatments, since both elements have direct importance on the synthesis of cell walls. As a vulgar concept, we can say that one element is the brick and the other the cement that builds the structure of the plant.

Functions of boron in the plant

Boron has several functions in the plant, among which the most important are:

Stimulates flower production and retention, pollen tube germination and elongation, and fruit and seed development.
It has activity on hormone production and regulation (as does zinc). Its absence causes the enzyme IAA-oxidase to reduce auxin functionality, thus preventing auxins from being found in sufficient concentrations in the flower to produce a positive stimulus.
Boron is involved in the production of proteins and the mobility of sugars and carbohydrates.
It participates in the formation of the cell wall and its stability.
Helps metabolize nitrogen.

The importance of molybdenum in plant nutrition

Molybdenum is another essential micronutrient for plants. Its differential value lies in the high mobility it has inside the plant, contrary to the rest of microelements.

Its activity is practically silent inside the plant, but really essential. While boron has a direct effect on flowering and sugar production, molybdenum acts covering basic functions, somewhat unknown to many people. For example, it is an integral part of redox reactions and enzymatic activity, such as the proper assimilation of nitrogen in the form of nitrate (nitrate reductase).

Molybdenum functions in the plant

It is involved in nitrogen fixation.
Molybdenum is a key component in two enzymes that convert nitrate to nitrite and then to ammonia. Its absence prevents the correct transformation of nitrogen into amino acids.
It offers synergies with iron assimilation.
It favors the transformation of phosphorus within the plant.

When is it recommended to apply boron and molybdenum to our crops?

The optimal nutrition of our crops is the one that provides all the elements continuously, anticipating the needs that the crop may have. However, the reality is that we cannot always do it or there are specific stages where greater quantities of these 2 elements are required.

It is common to find products containing a mixture of both, always with boron predominating because plants require it in higher concentration. Both boron and molybdenum have direct activity on pollination and fertilization of flowers, so the plant must have sufficient levels of these two microelements before flowering occurs.

While flowering in most tree crops is determined by the reserves of the previous season, at the current stage, with the addition of boron and molybdenum, the viability of these flowers is determined. Therefore, this contribution will allow the production of sufficient quality pollen and a greater number of fruits produced.

In deciduous crops, boron and molybdenum applications, among other elements, increase the production of proteins and sugars and their transport to the reserve organs, in this case the roots. This increases the crop's energy reserve for a successful future season.

The importance of boron and molybdenum in agriculture is so fundamental that Agran has designed Boramol, a product created to contain an ideal ratio of boron and molybdenum in suspension, which allows for improved mixtures with phytosanitary and other nutritional products.

However, the added value of Boramol is that it contains auxin and cytokinin inducers of natural origin, which allows it to act doubly on flowering and fruit pollination.

When boron is bound to these auxin promoters, pollen quality increases exponentially, increasing the availability of indoleacetic acid and boron to prevent oxidation of indoleacetic acid.

Advantages of Boramol:

Optimal ratio of boron and molybdenum to favor pollen activity and all processes related to fertilization.
It contains natural phytohormone inducers that work together with microelements to cover vital physiological stages.
Increases the mobility of sugars from the producing sources (leaves and stems) to the sinks (flowers, fruits and roots) in a concentrated formula that quickly corrects deficiencies of these two micronutrients.

This product can be applied foliar and in fertigation for all types of crops.
