Abstract

Methods of improving characteristics of plants and soil by administering an effective amount of a Kappaphycus based composition in low concentration applications are disclosed.

First claim

What is claimed is:

1. A method of enhancing a plant comprising administering to the plant in a condition of salt stress a composition comprising Kappaphycus alvarezzi in an amount of 0.0001-1% by weight to enhance the plant with resistance to salt stress.

2. The method of claim 1 , wherein the composition comprises an extract from Kappaphycus alvarezzi biomass.

3. The method of claim 1 , wherein the composition is administered directly to the plant.

4. The method of claim 1 , wherein the method comprises indirectly administering the composition to the plant.

5. The method of claim 3 , wherein the plant is a seed or a seedling when the composition is administered or first administered.

6. The method of claim 2 , wherein the composition is administered at a rate of about 1-125 gallons/acre for soil applications.

7. The method of claim 1 , wherein the method comprises repeated administration of the composition.

8. The method of claim 1 , wherein salt stress comprises a high salt condition of at least about 100 mM NaCl.

9. The method of claim 1 , wherein the enhanced resistance to salt stress produces increased root growth comprising an increased distance of root length from the plant meristem by at least 10%, increased total root length by at least 10%, or both, over an untreated control.

10. The method of claim 1 , wherein the enhanced resistance to salt stress produces increased plant growth comprising an increased plant dry weight by at least 10% over an untreated control.

11. The method of claim 1 , wherein the plant is a legume.

12. The method of claim 11 , wherein the legume is a bean.

13. The method of claim 1 , wherein the composition is applied at a rate of about 10-50 gallons/acre for foliar applications.

14. The method of claim 1 , wherein the method comprises administering the composition in combination with a microalgae composition that independently enhances at least one characteristic of the plant.

15. The method of claim 14 , wherein the microalgae composition comprises microalgae cells or microalgae derivatives obtained from microalgae cells, wherein the microalgae cells are selected from Chlorella cells, Aurantiochytrium cells, or a combination thereof.
