The present invention provides organic slow-acting fertilizer using psyllium seed husk and a method for producing the same. Macroelements or secondary elements selected from 12 essential nutrient elements (N, P, K, Ca, Mg, S, Fe, Mn, Cu, B, Mo, and Zn) for edible plants are extracted from each of oil cake (collectively referring to residue remaining after extraction of vegetable oil, and including soybean oil cake, palm oil cake, etc.), blood meal (livestock blood), dead fish or bonefish-containing by-products, bone meal, Dead Sea mineral, egg shell, seashell, oystershell, natural gypsum, dolomite, phyllite, and natural salt, by a predetermined extraction process, and are impregnated in larger amounts into a porous material such as zeolite, and organic fertilizers are produced in the form of psyllium seed husk-bound grains for more rapid and effective impregnation so that suitable proportions of element fertilizers can be supplied to each type of plant.

The present invention relates to compositions for increasing a nitrogen source life span in plant growth mediums as well as methods of making these compositions. The invention also relates to compositions and methods of reacting a nitrogen source with one or more nitrification inhibitors using standard equipment for producing nitrogen sourced particles.

Provided herein is technology relating to organic fertilizers and particularly, but not exclusively, to organic and/or biodegradable flocculants, methods of preparing organic fertilizers using an organic and/or biodegradable flocculant, and systems for treating water using an organic and/or biodegradable flocculant to prepare an organic fertilizer.

A controller for a compost system comprises a plurality of control outputs in communication with a plurality of compost devices. The control outputs are configured to identify an error condition of at least one of the plurality of compost devices. The controller is configured to control a first compost device configured to control a first environmental condition and control a second compost device configured to control a second environmental condition of a compost chamber. The controller is further configured to deactivate the first compost device in response to an error condition during a compost cycle. The controller controls the second compost device in response to the first compost device being deactivated preserving the compost cycle by compensating for the error condition in the first compost device.

A system and a method for treating biomass with a gas includes at least one conduit having at least one biomass inlet and at least one biomass outlet, at least one gas inlet and at least one gas outlet. The system further includes a transport unit configured to move the biomass through the conduit from the at least one biomass inlet to the at least one biomass outlet thereby defining a biomass transport direction. The system is configured such that gas flowing from the at least one gas inlet to the at least one gas outlet crosses the biomass transport direction.

Methods of delivering microorganisms loaded onto an inorganic porous medium. Methods of treating wastewater to increase effluent and biosolids quality. Methods of reducing ammonia and denitrifying wastewater effluent. Methods of reducing phosphorous concentration in wastewater effluent. Composition of biosolids derived from wastewater treatment. Wastewater treatment assemblage for increasing wastewater effluent and biosolids quality.

An assemblable appliance and method of recycling organic waste into biogas and liquid fertilizer, implementing essentially anaerobic digestion processes, is described. The assemblable appliance includes: a pliant structured exoskeletal envelope, pliable collapsible anaerobic digester and gas tank. A compact kit-of-parts for assembling the aforementioned appliance and respective method using the aforementioned appliance for recycling organic waste into biogas and liquid fertilizer are described.

A method for preparing an organic complex microelement fertilizer for engineering wound soil remediation includes compounding chitosan oligosaccharide or/and earthworm dung or/and silkworm sand, water or/and hydrogen peroxide, an organic complex trace element solution, polyethylene glycol octyl phenyl ether, and polysorbate under certain conditions. The present invention can significantly improve physical and chemical properties of engineering wounds, enhance effectiveness of trace elements in soil, and prevent plant physiological diseases due to lack of trace elements, and promote plant growth and development.

Provided herein is a process for producing one or more products from a lignocellulosic feedstock. The process comprises treating the lignocellulosic feedstock by contacting the feedstock at least sulfur dioxide, sulfurous acid, or a combination thereof to produce a pretreated feedstock comprising one or more sulfonic acids. A process stream comprising one or more sulfonic acids is subsequently treated in a wet oxidation step to produce a stream comprising at least soluble oxidized phenolic compounds. The soluble oxidized phenolic compounds are then fed to an anaerobic digestion to produce methane. Optionally, hydrogen sulfide is produced during the anaerobic digestion. The hydrogen sulfide may then be converted to an acid selected from sulfur dioxide, sulfurous acid or a combination thereof in one or more steps. The acid may then be re-used in treatment as desired.
