Boron is naturally present in all soil. It is one of the 114 elements that make up the earth, and every member of the plant world relies on it to grow. Boron not only plays an essential role in a plants reproductive cycle, controlling flowering, pollen production, and seed development, but also works in the primary cell structure of the plant and so affects almost every area of plant health and growth including root growth, nutrient uptake, fibre density and disease resistance.  Unfortunately, many Australian soils are on the most part, extremely deficient in boron.

OrganiBOR® is a naturally occurring, certified for organic use, magnesium/calcium borate that replenishes the boron levels in the soil in a controlled and natural way.

OrganiBOR® is designed to be applied once every 2-5 years depending on the crop, climatic and soil conditions, and will continually release boron over that period of time so the plants, vines or trees will have a continual supply of boron right through all of their growing phases. The effect on the tree is the same as if it was grown in boron rich soils.
