OrganiBOR is a slow release boron fertiliser, 10 percent boron by weight, in which the boron is bound to calcium and magnesium rather than sodium. It suits growers who want a soil applied boron source that releases over the season, and it is certified for use in organic gardening.
OrganiBOR is a natural calcium magnesium borate mineral. Unlike borax, which is a soluble sodium salt, its boron is bound to calcium and magnesium and it is not water soluble, so it is applied to the soil rather than sprayed.
Boron is used in small amounts and has a narrow margin between deficiency and toxicity. Over-application harms plants and soil, and because OrganiBOR releases slowly a mistake stays in the soil for a long time. Apply from a soil test and do not combine with other boron products without adding up the totals.
This product is used in minute amounts and should only be applied by advanced users or for approved organics with a soil prescription. Over application, even by a small amount, can be very detrimental to plant and soil health. We offer a soil prescription service, see where to test your soil, or email us at store@seaclifforganics.nz for more information about the services we provide.
