A method and apparatus for cleaning and recycling stack gas from coal-fired power plants, from natural or propane burning heating plants, or from cement kilns by using renewable catalysts of zeolite to separate pollutants into recyclable and reusable materials. The method reduces from the stack gas carbon monoxide (CO), carbon dioxide (CO.sub.2), nitrogen oxide (NOx), sulfur oxide (SOx) as well as halogens such as chloride and fluorides and trace metals particularly, mercury, lead, and zinc. The method and apparatus also result in production of fertilizer products by purging with gaseous or liquid nitrogen the zeolite beds through which the stack gas flows. The oxygen generated may be recycled to the burners in the plant.

A method for using treated biochar to reduce the overall environmental impact of farming and minimize the carbon footprint of farms is provided. The method comprising engaging in one or more of the following practices: (1) combining treated biochar with feed or using biochar as feed for animals to reduce methane from enteric fermentation and increase animal health and nutrition; (2) combining treated biochar with compost, animal bedding or manure piles to reduce odor and increase nutrient retention; (3) applying treated biochar to lagoons to reduce odor and treat water; (4) applying treated biochar to pastures to increase pasture health; (5) applying treated biochar to crops to increase crop productivity, healthier roots and prevent fertilizer leaching; and (6) using the carbon negativity of a produced biochar to reduce the overall farm or ranch carbon footprint.

A method and system is provided for using biochar in composting environments to control temperature, moisture, acid and pH levels, odors and bacterial cultures. The method further includes treating the biochar prior to combining it with the compost to further control such parameters.

Methods and systems for in situ electrochemical treatment of aqueous solutions used in agricultural systems, community systems and industrial systems. In aspects, is an in situ electrochemical method for the treatment of fertigation water, comprising: flowing the fertigation water through an electrochemical cell comprising at least one anode and at least one complementary cathode while simultaneously adjusting one or more of current density, flow rate and pH, wherein said flowing fertigation water contacts the anode and cathode causing one or more of: degradation of a recalcitrant organic contaminant, mineralization and solubilization of an organic, forming a disinfection agent against a pathogen, and maintaining nutrient levels in said fertigation water; and collecting treated effluent.

A method of buffering coco material includes cleaning a quantity of untreated coco material to result in cleaned coco material, applying buffered water to the cleaned coco material to produce treated coco material, aging the treated coco material to produce aged coco material, and cleaning the aged material to produce buffered coco material.

Compositions of a slow-release nitrogen-containing fertilizer and iron chelated to an aminopolycarboxylic acid or a polycarboxylic acid. The composition can be useful as a fertilizer for rapid greening of turfgrass.

In embodiments, the present invention relates to liquid formulations containing hydrophobic, biodegradable polymers dispersed within a Non-aqueous Organic Solvent Delivery System (NOSDS) that is designed to coat fertilizer granules with a hydrophobic film utilizing simple application equipment such as mixers, blenders and tumblers. This film can impede the dissolution of fertilizer components by water improving fertilizer efficiency. The NOSDS can be aprotic solvents, protic solvents and mixtures of protic and aprotic solvents which are environmentally friendly, have flashpoints above 145° F., and are inherently rated safe for contact with humans and animals. The hydrophobic polymers are the reaction product of aldehyde(s) and nitrogen containing compounds.
