A method for making a growing medium includes a step of combining tree bark and/or wood components together to form an initial composition; heating the initial composition to a temperature greater than about 149° C. under steam in a pressurized vessel; processing the initial composition through a refiner with a plurality of opposing disks to obtain the fibrous growing medium, the refiner separating fibers from each other; wherein the growing medium has total porosity of 88 volume % or more.

formaldehyde-based polymer composite is coated on a surface of the biodegradable polymer fabric, and is embedded in meshes of the biodegradable polymer fabric. There is intermolecular hydrogen-bond interaction between the biodegradable urea-formaldehyde-based polymer composite and the biodegradable polymer fabric.

A method for providing landscaping materials wherein a predetermined layer of a rubber mulch is placed on a predetermined area of soil and the rubber mulch layer is sprayed with a urethane binder material. Also, there is a method for providing landscaping materials wherein a predetermined area of soil is prepared for treatment and then treated with a weed barrier. Then, a predetermined layer of rubber mulch is applied to the weed barrier treated soil and the rubber mulch layer is sprayed with a urethane binder material. Additional layers of particulate material and binder layer can be applied to the top binder layer in each method.

The present disclosure relates to a barrier paper comprising a paper coated with polyvinyl alcohol composition, and a method for reducing diffusion of soil fumigant using the same.

Lignin formulations for making light-selective mulch, methods of making such lignin formulations, light-selective mulches comprising substrates treated with lignin formulations, and methods of making such light-selective mulches. Some methods involve preparing aqueous lignin formulations that can be used as coatings that, in turn, can be applied to a substrate, such as a paper web, to form a biodegradable, light-selective mulch. Some such mulches blocks at least some light in the ultraviolet and blue/green ranges (350 nm to 500 nm) of the visible light spectrum to inhibit weed growth below the mulch, while also transmitting light in the red/infrared ranges to heat the soil below the mulch.

A hydromulch composition compromising an oil-extruded cottonseed meal processed from a non-delinted cottonseed. The oil-extruded fuzzy cottonseed meal can optionally be combined with one or more super absorbent polymers, such as polyaspartate and polyacrylate polymers and other additives. The hydromulch composition can additionally include one or more microorganisms including but not limited to bacteria and mycorrhizae configured to provide symbiotic relationship with treated soil and plants to increase water and nutrient uptake in the treated plants or soil. The hydromulch composition can further be combined with a dispersant, such as water to make slurry for spray on application to a desired treatment surface.
