Claims39
A method for controlling the growth of invasive plant species in an existing perennial grass community comprising applying boron to an area of the existing perennial grass community to achieve a soluble boron concentration in the soil of the existing perennial grass community from about 0.5 milligrams per liter to about 50 milligrams per liter, wherein the growth of the invasive plant species is controlled.
A method of controlling the growth of at least one invasive plant species at a locus to be treated comprising the steps of:
- a) determining an invasive plant species to be controlled in an existing perennial grass community;
- b) measuring the soluble boron concentrations in the soil of the existing perennial grass community;
- c) applying boron to an area of the existing perennial grass community to achieve a soluble boron concentration in the soil of the existing perennial grass community from about 0.5 milligrams per liter to about 50 milligrams per liter.
A method for controlling the growth of invasive plant species in an existing perennial grass community comprising applying boron to an area of the existing perennial grass community to achieve a soluble boron concentration in the soil of the existing perennial grass community from about 0.5 milligrams per liter to about 50 milligrams per liter in the uppermost about 1 inch of soil.
A method for controlling the growth of invasive plant species in an existing perennial grass community comprising applying copper to an area of the existing perennial grass community to achieve a soluble copper concentration in the soil of the existing perennial grass community from about 0.1 milligrams per liter to about 50 milligrams per liter, wherein the growth of the invasive plant species is controlled.
A method of controlling the growth of at least one invasive plant species at a locus to be treated comprising the steps of:
- a) determining an invasive plant species to be controlled in an existing perennial grass community;
- b) measuring the soluble copper concentrations in the soil of the existing perennial grass community;
- c) applying copper to an area of the existing perennial grass community to achieve a soluble copper concentration in the soil of the existing perennial grass community from about 0.1 milligrams per liter to about 50 milligrams per liter.
A method for controlling the growth of invasive plant species in an existing perennial grass community comprising applying copper to an area of the existing perennial grass community to achieve a soluble copper concentration in the soil of the existing perennial grass community from about 0.1 milligrams per liter to about 50 milligrams per liter in the uppermost about 1 inch of soil.
