Abstract
Disclosed are methods of improving germination rates of plants/crops, as well as preventing or arresting water evaporation loss from targeted soil areas, which allows for improved water usage efficiency by crops, plants, grasses, vegetation, etc.
Claims30
A method of decreasing water evaporation from soil, the method comprising:
- introducing a bulk additive to a target soil area;
- and
- contacting a top layer of the target soil area with a surface additive,
- wherein the step of introducing the bulk additive to a target soil area comprises applying the bulk additive to the surface of target soil area then mixing the bulk additive into the target soil area at a predetermined depth.

A method of decreasing water evaporation from soil, the method comprising:
- introducing a bulk additive to a target soil area;
- and
- contacting a top layer of the target soil area with a surface additive,
- wherein the step of introducing the bulk additive to a target soil area comprises:
- preparing a mixture comprising the bulk additive and a pre-mix soil and thereafter contacting the mixture with the target soil area.
2 more elements
A method of decreasing water evaporation from soil, the method comprising:
- introducing a bulk additive to a target soil area;
- and
- contacting a top layer of the target soil area with a surface additive,
- wherein contacting the top layer of soil comprises spraying an aqueous mixture comprising the surface additive onto the soil.
1 more element
A method of decreasing water evaporation from soil, the method comprising:
