Ulexite is a unique sodium-calcium borate mineral. It is ideally suited to ground application as a means of correcting boron deficiency in a wide range of plant species.
Applied either alone, or as a component of a mult-nutrient granular bulk blend, ulexite offers a number of interesting attributes relative to other, highly soluble forms of boron. The most significant of these is ulexite`s disolution rate.
Unlike highly soluble borates, ulexite offers a slow boron release consistent with the gradual uptake of boron required by plants.
For many plant species, the threshold between boron deficiency and boron toxicity is quite narrow. Applying a slow release form of boron can significantly reduce this toxicity risk.
Boron is readily leached from the soil. In areas of high rainfall a significant proportion of the boron contained in soluble borates simply never reaches the plant. With a controlled solubility borate such as ulexite, the propensity for leaching is substantially reduced.
Finally, ulexite`s cost per unit boron is highly attractive relative to most commonly used alternatives.
Bisley supplies ulexite in a range of grades from 30% to over 50% B2O3. Various product forms are available including powder and granules suited to forestry applications or blending with other granular fertilisers.
