WHAT WE CLAIM IS:

1. A composition including the elements nitrogen and magnesium for application to a substrate, thereby increasing elemental uptake of calcium and/or magnesium in biological life forms supported thereon.

2. A composition as claimed in claim 1 wherein the composition does not contain calcium.

3. A composition as claimed in either claim 1 or claim 2 wherein magnesium and nitrogen are in cationic form and are combined with anions to produce a magnesium salt and a nitrogenous salt.

4. A composition as claimed in claim 3 wherein the anions are chlorides and/or sulphates.

5. A composition as claimed in claim 4 wherein the salt products are magnesium chloride and ammonium sulphate.

6. A composition as claimed in claim 1 or claim 2 wherein nitrogen is in anionic form and is combined with a cation to form a salt.

7. A composition according to the above claim wherein the cation is selected to improve pasture quality and may include any one or more of phosphorous, sodium, calcium, copper, cobalt, zinc, copper, selenium, iodine and boron.

8. A composition as claimed in any one of the above claims wherein the ratio of the magnesium containing compound is substantially 55-70%: 45- 30%.

9. A composition as claimed above wherein the ratio is 66:34.

10. A method of increasing calcium and/or magnesium levels in animals, thereby preventing or reducing health problems therein, comprising applying a composition including nitrogen and/or magnesium to a substrate upon which said animals feed.

11. A method as claimed in claim 10 wherein said animals are dairy cows.

12. A method as claimed in claim 10 or 11 wherein said composition is applied to pasture to be consumed after the animals giving birth and operates to increase calcium and magnesium levels in the animal.

13. A method as claimed in any one of claims 10-12 wherein said health problems are milk fever and/or grass staggers.

14. A method according to any one of claims 10-13 wherein the application of the compound is foliar application in liquid solution.

15. A composition substantially as described or claimed herein with reference to any example thereof.

16. A method of increasing calcium and/or magnesium levels in animals substantially as described or claimed herein with reference to any example thereof.

17. Any invention claimed or described herein.
