Abstract
The invention is directed to compositions comprising at least one agricultural biomass, at least one nitrogen source, at least one organic acid and at least one active agent wherein the agricultural biomass is impregnated with about 5% wt to about 45% wt of the active agent. Methods of their preparation and methods of use are also described. The composition effectively reduces the leaching of, and facilitates the metering of, loaded active agents for plant protection.
Claims17
A composition comprising biochar, at least one nitrogen source, at least one organic acid and at least one active agent wherein the biochar is impregnated with about 5% wt to about 45% wt of the active agent, and further wherein the biochar has a bulk density of less than about 40 pounds per cubic foot and has a size of about 90-100% passing through a ¼″ mesh screen and about 50% or more passing through a 4 mesh screen;
- or a size of about 90-100% passing through a No. 4 mesh screen and about 70% or more passing through a No. 10 mesh screen;
- or a size of about 90-100% passing through a No. 10 mesh screen and about 50% or more passing through a No. 45 mesh screen.
A method for minimizing leaching of an active agent into water sources comprising applying to soil a composition comprising biochar, at least one nitrogen source, at least one organic acid and at least one active agent wherein the biochar is impregnated with about 5% wt to about 45% wt of the active agent, and further wherein the biochar has a bulk density of less than about 40 pounds per cubic foot and has a size of about 90-100% passing through a ¼″ mesh screen and about 50% or more passing through a 4 mesh screen;
- or a size of about 90-100% passing through a No. 4 mesh screen and about 70% or more passing through a No. 10 mesh screen;
- or a size of about 90-100% passing through a No. 10 mesh screen and about 50% or more passing through a No. 45 mesh screen.
