Abstract

A mulch composition includes a blend of about 50-85 wt. % fibrous straw, based on the total weight of the composition; about 10-30 wt. % refined pulp fibers, based on the total weight of the composition; and about 10-40 wt. % fibrous wood components, based on the total weight of the composition, the blend having about 10-15 wt. % of particles having particle size of 2360 pm or greater.

Claims (17)

1 . A blended mulch composition comprising:

about 50-85 vol. % fibrous straw, based on the total volume of the composition;

about 10-30 vol. % refined pulp fibers, based on the total volume of the composition; and

about 10-40 vol. % fibrous wood components, based on the total volume of the composition,

the blend having a pH of about 5 to 6.5 and electrical conductivity greater than about 0.55 mmhos/cm.

2 . The blended mulch composition of claim 1 , wherein the fibrous wood components are hammermilled.

3 . The blended mulch composition of claim 1 , wherein the fibrous straw comprises wheat straw.

4 . The blended mulch composition of claim 1 , wherein the fibrous wood components include a surfactant.

5 . The blended mulch composition of claim 1 further comprising at least one of fertilizer(s), macronutrient(s), micronutrient(s), mineral(s), binder(s), natural gum(s), interlocking fiber(s), biostimulant(s), ceramic particle(s), and combinations thereof.

6 . The blended mulch composition of claim 1 , wherein the composition has a higher percentage of particles on sieve #16 than on sieve #8.

7 . A hydraulic mulch composition comprising:

a blend of fibrous straw, refined pulp fibers, and fibrous wood components in a ratio of about 5:1:1 to 8.5:3:4, the blend having a loose bulk density of about 5-7 lb/ft 3 .

8 . The hydraulic mulch composition of claim 7 , wherein the composition has electrical conductivity greater than about 0.55 mmhos/cm.

9 . The hydraulic mulch composition of claim 7 , further comprising a surfactant, a dye, or both.

10 . The hydraulic mulch composition of claim 7 , wherein the wood components are hammermilled.

11 . The hydraulic mulch composition of claim 7 , wherein the pH is above about 5.

12 . The hydraulic mulch composition of claim 7 , wherein the fibrous straw comprises wheat straw.
