A humic acid composition includes fulvic acid, ulmic acid and black humic acid. Fulvic acid is in an amount ranging from 64% to 98 wt % based on a sum weight of fulvic acid, ulmic acid and black humic acid. The content of phenol hydroxyl groups is in a range from 0.76 mmol/g to 2.42 mmol/g in the humic acid composition. The humic acid composition contains a high content of fulvic acid with small molecular weight and a high content of active functional groups, and a high content of phenolic hydroxyl in the active groups. The humic acid composition can provide microbial organic source for soil directly, and improve the nutrient of crops and the soil environment in rhizosphere to promote the breeding of microorganism and delay the attenuation rate of soil microbes.

A method is provided for producing a biochar solution. The method comprises the steps of collecting biochar particles, dispersing the biochar particles in a liquid solution and adding a stabilizing agent to keep the biochar in flowable suspension. The stabilizing agent may be added to the liquid solution or to the biochar prior to placing the biochar in solution.

An artificial soil for growing vegetation includes a mixture of biosolids from a wastewater treatment plant, at least one of synthetic gypsum and a gypsum-depleted by-product, and a calcium compound from at least one of a lime kiln dust, a fluidized bed ash, and a ball mill lime. The calcium compound is present in an amount sufficient to heat the mixture to at least about 132 F. following mixing. The mixture may include at least one of silica and alumina. The artificial soil may include hydrated lime. The mixture may include at least about 1/9 by volume of biosolids and/or from about to about by volume of the calcium compound. A method of manufacturing the artificial soil includes mixing biosolids with at least one of synthetic gypsum and a gypsum-depleted by-product and at least one of a lime kiln dust, a fluidized bed ash, and a ball mill lime.

An erosion control slurry is disclosed. The slurry includes water and a substrate, wherein the substrate comprises: mulch at a weight of x; bentonite clay at a weight of about 0.25x to about 0.495x; and cellulosic water dispersible polymer or starch at a weight of about 0.0025x to about 0.125x. Also disclosed are a substrate that can be mixed with liquid to provide an erosion control slurry, and methods of controlling or reducing erosion.

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.

Treat an aggregation of particulates with two different aqueous mixtures, first with an aqueous mixture containing a sulfonated aromatic polymer component and then with an aqueous mixture containing polyethylene oxide.

A method including providing an aqueous mixture containing a sulfonated aromatic polymer component and applying the aqueous mixture to an aggregation of particulates sufficient to increase the water holding capacity of the aggregation of particulates.

Field harvested culture mix is used to inoculate organic waste and produce an inoculated waste material, where the field harvested culture mix includes soil derived microbes. The inoculated waste material is shredded to produce shredded inoculated waste material which is fermented the shredded inoculated waste material for at least 7 days. Contents from the fermenter are then transferred into a dewatering device to produce dewatered contents which are then separated into soluble and suspended products.

This invention relates to bio-renewable fertilizer compositions and methods of making and using the bio-renewable fertilizer compositions. In particular, the fertilizer compositions include biodegradable nutrient carriers, which have naturally derived, bio-renewable nitrogen content. The fertilizer compositions also contain biodegradable stabilizer.

Polyurethane foam flakes for use as additive to soil and/or other natural plant growth media for improving the water retention and/or reduction of the methane emission.
