摘要:
The invention is directed to processes for treating biosolids that result in high-value, nitrogen-containing, slow-release, organically-augmented inorganic fertilizer that are competitive with less valuable or more costly conventional commercially manufactured fertilizers. The process involves conditioning traditional waste-water biosolids and processing the conditioned biosolids continuously in a high throughput manufacturing facility. The exothermic design and closed loop control of the primary reaction vessel decreases significantly the amount of power necessary to run a manufacturing facility. The process utilizes green technologies to facilitate decreased waste and enhanced air quality standards over traditional processing plants. The fertilizer produced from recovered biosolid waste is safe and meets or exceeds the United States Environment Protection Agency (USEPA) Class A and Exceptional Quality standards and is not subject to restrictions or regulations.

The present invention provides a new liquid fertilizer comprised of potassium sulfite and potassium bisulfite, with neutral to slightly alkaline pH, relatively lower salt index and potentially lower phytotoxicity damage compared to other sources of potassium and sulfur products applied in equal amounts as a starter fertilizer. More specifically, the present invention further relates to methods for fertilizing using a composition of potassium sulfite and potassium bisulfite, particularly as a starter fertilizer, in-furrow fertilizer, side dress fertilizer, and for foliar, broadcast, soil injection and fertigation applications. The fertilizer composition is comprised primarily of potassium sulfite and potassium bisulfite (with the fertilizer grade of 0-0-23-8S).
摘要:
System for the bio-treatment of organic waste by means of insect larvae comprising a tank provided with removable cover and means for ventilation and temperature control able to induce migration of the larvae outside the waste mass when in a desired larval development stadium, means for distributing in many times the various waste layers and for removing the same at the end of the treatment and means for distributing the larvae inside the tank and for collecting and storing the larvae at the end of the treatment. Method for the bio-treatment of organic waste by means of larval stadium insects provided with the step of placing a first waste layer inside a tank (1), placing insect larvae or eggs on said layer and adding other waste layers at prefixed and shorter time intervals than the larvae development time, inducing the spontaneous migration of the larvae towards suitable collecting areas by means of temperature and humidity control and removing the treated waste from the tank

摘要:
A bactericidal and fungicidal composition having fertilizer properties, the composition containing a percentage of potassium polyposphite is disclosed. The composition is useful as a fungicide, bactericide, and as a fertilizer for application to plants and, particularly, commercial crops. A method of making the polyposphite composition is described, as well as methods of using same.
摘要:
A material (such as potassium hydroxide or ammonia) capable of reacting with ambient carbon dioxide to produce fertilizer is placed in the path of ambient air movement. Desirably the material is associated with a fabric which in turn is associated with a vane of a vertical axis wind turbine, the turbine performing useful work as well as supporting the material which produces a fertilizer. A misting system controlled by a controller may automatically apply a water mist to the material if the humidity is below a predetermined level. The fabric with produced nitrogen and/or potassium fertilizer may be placed directly into contact with soil, or shredded first, or burned to produce energy and an ash (and the ash applied to the soil). The wind turbine may have a convenient, versatile mounting system with three adjustable legs supporting a central component, and the spokes of the wind turbine may be slotted for easy assembly with vanes.

摘要:
A novel phosphatic/potash compound fertilizer and a method of producing the same are provided for improving the solubility of phosphate components contained in an incinerated ash residue of chicken droppings for efficient utilization of the ash residue, with the alkalis of the lime component origin being neutralized. Thus, at least one powder selected from among a basic potassium compound powder and a water-granulated blast furnace slag powder is admixed with an incinerated ash residue of chicken droppings, a mineral acid is added to the mixture and reactions are allowed to proceed to maintain the reaction system at a high temperature by utilizing the heat of neutralization generated by the reaction between the basic potassium compound and/or water-granulated blast furnace slag powder and the mineral acid thereby convert hardly soluble phosphatic components contained in the incinerated chicken dropping ash residue to effective components improved in solubility, while maintaining the reaction mixture at about neutrality or weak acidity.
摘要:
There is provided a method for producing granular fertilisers that includes at least one structural compound based on at least two salts. The method includes the steps of disposing of at least one salt that includes nitrogen, humidifying the at least one salt, mixing the at least one humidified salt with at least one substance comprising at least one alkaline and/or alkaline-earth element and/or at least one element of group IV, producing a granular fertiliser by granulation of the mixture, and cooling the granular fertiliser. There is also provided a granular fertiliser comprising nitrogen and having a pH in the range of 3≦pH≦7. The granular fertiliser shows a strength σ of σ≧3 MPa and includes a concentration cSC of at least one structural compound with cSC≧50 wt.-%.
摘要:
This invention is a method for conveniently and economically manufacturing a zeolite-containing, slow-release fertilizer. For example, according to the method, crude zeolite ore is ground into particles. Crude waste precipitate from sugar beet refining, containing calcium carbonate, is also ground, screened, or shaken to a similar consistency. These components are then mixed in a roughly 2:1 weight ratio, zeolite:calcium carbonate, and preferably slurried with water. The water may be present in an amount, by weight, generally the same as the calcium carbonate component. After drying the mixed slurry, these mixed fertilizer precursor particles are processed for distribution using conventional means. When the precursor particles are applied to the field, they may be charged to become active, slow-release fertilizer by the addition of commercial agricultural fertilizers to the soil. Such commercial fertilizers may contain, for example, potassium and phosphorus. To prepare an application-ready fertilizer, commercial ammonium poly-phosphate solution (known in the industry as null10-34-0 solutionnull), or a similar substance, may also be mixed with the slurry at about 10 weight % of the zeolite. This way, the final mixture is ready as active fertilizer when applied to the field. An optional dust control agent may also be added to the zeolite: calcium carbonate mixture if desirable.
