Abstract
Disclosed are methods and devices that can improve water usage by plants and grasses by, for example, inducing preferential root tropism and assisting in redistributing water within the soil.
Claims23
A method of affecting a root system of a plant comprising:
- inserting at least a portion of a root device in the ground proximate to a seed or plant,
- the root device comprising a structure extending in a substantially longitudinal direction.
A method of (i) increasing root length of a plant, (ii) inducing tropism of a plant root towards a water reservoir in soil, (iii) promoting the growth of a root towards water in soil, and/or (iv) increasing the lifespan of a plant comprising:
- contacting a plant or a seed with soil;
- and
- inserting at least a portion of a root device in the soil proximate to the seed or the plant, the root device comprising a structure extending in a substantially longitudinal direction.
A method of (i) increasing root length of a plant, (ii) inducing tropism of a plant root towards a water reservoir in soil, (iii) promoting the growth of a root towards water in soil, and/or (iv) increasing the lifespan of a plant comprising:
- inserting at least a portion of a root device in soil;
- and
- contacting a plant or a seed to the soil at a location proximate to the root device;
- wherein the root device comprises a structure extending in a substantially longitudinal direction.
A method of inducing tropism of a root, the method comprising:
- inserting at least a portion of a root device in soil proximate to a location wherein a seed or plant is contacted with the soil,
- the root device comprising a structure extending in a substantially longitudinal direction.
A device for increasing the root length of a plant comprising a structure extending in a substantially longitudinal direction, and having a cross-sectional area comprising an outer wall and an inner wall.
