What it is

Cobalt sulphate is a water soluble cobalt salt. The product supplies 10% cobalt and dissolves in water for spraying or irrigation.

What it does

• Cobalt is needed by the rhizobia bacteria that fix nitrogen in legume root nodules, so legumes and clover based pasture are where a cobalt response is most likely.
• Cobalt is essential for grazing animals (it is the core of vitamin B12), and in New Zealand cobalt is usually applied to pasture for stock health rather than for the plants themselves.
• Cobalt is not an essential nutrient for most plants, so it is not a general garden input.

Analysis

• Cobalt (Co) 10%

How to use

• Dissolve in water and spray for even distribution.
• Apply only from a soil or herbage test. Ask us for a rate for your situation if your prescription does not give one.

Watch out

Cobalt is used in minute amounts and over application, even by a small amount, can be very detrimental to plant and soil health. Excess cobalt is toxic to plants and it does not leach away. Apply only what a test or prescription calls for.

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.
