Fertiliser ADOB Boron

Characteristics

ADOB® Boron is a high-purity, binary-nutrient fertiliser containing 11.1% boron (B) and 5.8% nitrogen. It is a homogeneous aqueous solution, which makes it user-friendly and ensures that nutrients are highly available to plants’ leaves and roots. It can be applied through fertigation and hydroponics and is especially recommended for foliar application.

An adequate level of boron is essential for maintaining numerous boron enzymatic plant activities in arable and horticultural crops. These activities include synthesis, structuring and stabilization of cell walls, support of the structural, functional integrity and elasticity of cell membranes, and proper differentiation and development of apical meristems. Boron is also central in the metabolism of the auxin indole-acetic acid (IAA) and in the regulation of the mitosis process during cell division through production of nucleic acids (DNA, RNA).

Appropriate treatments with ADOB® Boron can prevent boron shortage in crops, especially in cereals, rapeseed, sugar beet, potato, brassica vegetables, legumes, and pome and stone fruits. It therefore prevents and corrects the serious physiological disorders which lead to heavy losses of yield quantity and decreased quality. The sparse internal transport of boron in many plants requires several spray applications of the product during critical growth stages.

ADOB® Boron is allowed to be applied in ecological agriculture. Certificate numer – NE/562/2021.
