AgronoBlog – Agriculture Blog Calcium is an element that is absorbed in the form of divalent Calcium cation (Ca2+) and is abundant in the soil, however, at certain stages of crop development, plants may express symptoms of deficiency of said element.
Calcium is absorbed through the tissue of “tender” roots. This is one of the main reasons for calcium deficiency in the plant. When a plant does not emit absorption roots correctly, it can present problems with calcium, even though it is found abundant in the soil, hence the importance of maintaining root biostimulation and of the entire plant and of making applications of available Calcium together with biostimulant substances.
Another problem that reduces the assimilation of Calcium by plants is the acidic or very alkaline pH in the soil solution, both conditions tend to promote the formation of Calcium compounds and precipitate it (mainly with Phosphorus).
Calcium absorption and its transport are limited to the movement of water through the xylem, for this reason, days with short photoperiods, low temperatures and periods of poor irrigation management will promote nutrient deficiency in the plant.
Generally, Calcium deficiencies will appear in the new tissues (deformation of the leaves in the shoots), this is largely due to the fact that Calcium moves via the xylem limited by the flow of water and because Calcium is a promoter of the correct cell division, by providing structure to the cell wall. It is also common in some fruits to find Calcium deficiencies in the form of blossom end rot.
When there is an excess of Calcium in the soil, symptoms of Boron deficiency may also appear, derived from the high pH and the tendency of Boron to react with Calcium and affect its absorption. It has also been proven in some species that Boron deficiencies induce the appearance of Calcium deficiencies. For this reason, Calcium and Boron are generally applied together via foliar spray.
Finally, Molybdenum is an element that tends to be more assimilable in high pH conditions, under acidic conditions, it will be less absorbed by the plant. In some crops, Molybdenum deficiency affects pollen formation and size. For these reasons, the application of Calcium-Boron-Molybdenum complexes is recommended, mainly in flowering and fruit development.
Neptunus Biotech has biostimulant and nutritional products, with microalgae technology, which provide nutrients of organic origin of high quality and assimilation; but that also contain substances (from microalgae) that activate the assimilation and movement of nutrients within the plant. For this case, a clearly necessary product is Nerthus Ca•B•Mo.
Nerthus Ca•B•Mo, is a product formulated with high technology (microalgae) rich in Calcium, Boron and Molybdenum, with a double function: it provides Calcium, Boron and Molybdenum but also promotes the absorption of these nutrients present in the soil, thanks to its biostimulant substances (phytohormones, free amino acids, antioxidants, etc.) from microalgae.
Nerthus Ca•B•Mo, is a product of natural origin and is OMRI certified for use in organic crop production.
