LIGHT-SELECTIVE MULCH
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.

SEEDING FORMULATION FOR WOODY PLANTS AND PRE-TREATMENT OF LAND SURFACES
The present disclosure provides a seeding formulation for woody plants and a pre-treatment of surfaces (e.g. rocks, waste rocks, tailings, overburden) on disturbed and degraded lands. The seeding formulation includes a mix of woody trees or shrubs seeds, organic mulch, beneficial microbial populations, mineral fertilizer, adhesive, absorbent polymer, and water. The pre-treatment of surfaces refers to the spreading or mixing of surfaces with organic biomass. Methods of preparing and applying the seeding formulation and pre-treatment are also disclosed. The formulation is used for the phytoremediation, ecological restoration, land reclamation, environmental rehabilitation, revitalization, revegetation, and reforestation of disturbed and degraded lands.

CELLULOSE DERIVED HYDROPHOBIC, BIO-DEGRADABLE FILMS FOR MULCH & OTHER APPLICATIONS
The present invention describes synthesis and properties of cellulose based biodegradable hydrophobic mulch film for agricultural applications. The invented method can also be used to obtain an highly hydrophobic mulch film. Cellulose, the most abundant natural polymer is chemically modified to make bio-degradable, mulch films that are partially air permeable but water impermeable. The water impermeability can be changed by varying the processing conditions. The film can be multi-functional; that is besides providing the water impermeability the film can also be customized to adjust the pH of soil and to deliver herbicides or fertilizers to the soil. Other lignocellulosic materials or different combinations of synthetic fibers, fabrics or polymers and cellulose materials including newsprint can also be used to make the biodegradable hydrophobic film. Additionally, the invention can be used to make biodegradable extremely hydrophobic self-cleaning products for other hydrophobic applications such as packaging materials or disposable water-proof clothing.

METHOD FOR CONTROLLING DECOMPOSITION OF CORROSION-RESISTANT PAPER
There is provided: a method for controlling corrosion-resistant paper with easy decomposability, whereby the paper has corrosion resistance against decomposition due to microorganisms in soil when raising seedlings, the paper retains satisfactory strength during agricultural planting, and desired decomposability is given to the paper after planting or after harvest of crops; and a method for producing corrosion-resistant paper with controlled decomposability. The controlling method is subjected to corrosion-resistant paper containing paper with cellulose fibers and a carboxylic acid crosslinking agent at least partially bonded to each other, the controlling method including a step for treating the corrosion-resistant paper with alkali; and the producing method comprises a step for applying a processing solution containing a carboxylic acid crosslinking agent to paper containing cellulose fibers, a step for subjecting the paper to a heating treatment, and a step for treating the paper undergone the heating treatment with an alkali.

Process for producing hydro-mulch composition from muck
A combination of mulch and sterilized organic fertilizer is provided for hydro seeding and hydro-mulching for seed establishment and erosion control. The composition includes hammer milled straw, horse manure and urine, sterilized with heat and processed to provide an optimal particle size. The incorporation of horse manure utilizes a dispersible natural fertilizer collected and processed within a certain time frame which provides an efficient method of recycling green horse manure and liquid waste having a higher acidity than decomposed animal waste. Tackifiers and flocculants such as ground paper aid pumpability and help tack the straw fibers to the ground. The equipment includes a gas heat source, a dryer vessel and a processing unit. The dryer vessel receives the bedding composed of straw and manure for contact with the heated gases to convert the same to a sterilized dry material.
