Definitions

  • the invention is directed to organic fertilizers together with methods and apparatus for their manufacture including sterilization and enriching.
  • Statement of the Art Over the years chemically treated soils have been found to undergo a decrease in fertility and a reduction in the quality of plants produced. The microbiological community has been found to have been altered. The soil has becoming nearly sterile of living organisms. The soil became hard, less capable of taking in water. Humus, the primary nutrient conveyor from soil to plant, is decreased and soil tilth is greatly reduced. In healthy soils metabolites that can be directly assimilated by the plants are acted upon by the soil microbes to generate vitamins, auxins, gebberellins, antibodies, enzymes, and hormones.
  • top soil is considered one of the nation's greatest natural resources.
  • chemical fertilizers in 1940 and the subsequent changes in farm practices the natural microbiology humus content of U.S. top soil has depleted from 4%-6% of the topsoil to today's humus content of only about 1.5% of the topsoil's content.
  • leaching cannot be controlled.
  • Below a 2% level there exist insufficient metallic trace elements to form good enzyme systems in plants.
  • a recent approach to fertilizer use has been expressed by the maxim "feed the soil's bacteria, and the soil's bacteria will feed the plants.” Bacteria alter fertilizer constituents making them assumable as nutrients for the growth of the plants. Before they are suitable for plant use, microbes activity typically causes alterations changing compounds to the "ate or ide” form such as nitrate, phosphate, sulphate, chloride, borate, and molbedate. The necessity that fertilizer be water soluble is a misnomer. Producing organic fertilizer by composting leads to as much as 60-80% losses in loss of nutrients. Appreciable quantities of nitrogen in the form of NH 4 are lost during the composting process due to the breakdown of proteinac ⁇ ous compounds found in the original organic materials.
  • nutrient loss results from the bacterial oxidation of the original organic material.
  • This oxidation is represented by the following expression: + 60 2 ⁇ 6C0 2 t + 6H 2 0t + energy
  • oxidation results in the loss of carbon to the environment in the form of carbon dioxide.
  • energy is also lost to the environment.
  • Composting is a destructive process, which results in the reduction of high energy molecules to a final low energy form.
  • the subsequent spreading of composted material onto farm land effectively plants weed seeds in the farm land.
  • composting is not generally viewed with favor as an efficient means of producing a viable organic fertilizer.
  • the present invention provides an apparatus and method for promoting nitrogen, mineral, and nutrient retention in an organic fertilizer product so that the retained nutrients can later be assimilated by bacteria residing in the soil being fertilized.
  • the bacteria in turn utilize the fertilizer to produce substances which may be taken and used by plants for their enhanced growth. It has been discovered that plants are fed from matter acted upon by soil bacteria. The bacteria, in turn, are fed by the nutrient components of an organic fertilizer. This plant growth cycle is in opposition to the old adage that "fertilizer feeds the soil and the soil feeds the plants.”
  • fertilizer is a food for soil- borne bacteria.
  • the manufactured fertilizer is produced sterile of bacteria so that it remains intact, inert and unaltered until its application on the soil.
  • the total nutrient content of the organic material is largely locked into the material at the time of processing.
  • the processing makes the energy of complex molecules contained within the fertilizer available to soil microbes upon the subsequent application of the processed fertilizer to the soil.
  • the instant process provides a fertilizer which is well adapted for working in harmony with the natural processes occurring in the soil.
  • An example of this is the conversion of the a ino acids NH 2 NH 3 by common heterotrophic bacteria.
  • NH 3 is rapidly converted into NH 4 in the soil.
  • NH is converted to the more stable NO 3 as shown by the following expression:
  • the instant fertilizer includes a formulation which provides a means of time-releasing nitrogen for the use of plants.
  • the nitrogen is made available to the plants.
  • organic fertilizer produced from organic matter such as manure, fish, and crop waste, is sterilized. Sterilization destroys the bacteria population within the organic fertilizer, thereby curtailing, if not eliminating, any bacteria-promoted oxidation of the constituent elements and compounds found in the organic fertilizer. Furthermore, the sterilization effectively kills any weed seeds found in the organic matter. Due to the effects of sterilization, the resulting fertilizer can be stored for extended periods of time without any significant degradation in the nutrient content of the fertilizer. The resultant fertilizer may be applied without further treatment of the soil. The native bacteria populations in the soil readily assume the fertilizer, and process it for assimilation by the plants growing in the soil.
  • the instant invention discloses a method wherein the acid is added, a desired acidic state is achieved, and thereafter a anhydrous ammonium gas is injected as a base to sharply alter the pH, temperature, enrich the mixture and simultaneously dry the biomass.
  • the method of this invention has produced organic fertilizers with nitrogen and other constituent fractions comparable to chemical fertilizers, thereby eliminating the nutrient losses previously experienced in conventional organic fertilizer- producing methods.
  • the invention produced fertilizers which have been substantially tested and have been found to have retained their nitrogen levels after years of storage.
  • the fertilizer of the invention When the fertilizer of the invention is used on soils with leached characteristics, favorable results are realized because the fertilizer not only supplies nutrients to the soil but furthermore, the fertilizer provides organic material to feed the micro organisms in the soil, thereby facilitating the processing of plant nutrients into a usable form.
  • a beneficial fertilizer is not necessarily water soluble; instead the fertilizer must be assumable by the bacteria which consume the fertilizer. In so doing the bacteria alters the components of the fertilizer to render them assumable by the plants. It is further believed that the bacteria may in some instances feed on the components of the fertilizer and subsequently produce excretes which are assumable by the plant, where the fertilizer was not previously assumable directly.
  • the new organic fertilizer is thus bacteria assumable, and not necessarily water soluble.
  • the instant invention provides an apparatus adapted for formulating organic fertilizer.
  • the apparatus is a total system to formulate organic fertilizer, which is hereafter described.
  • the apparatus of the invention includes a container means adapted for receiving and containing a quantity of organic fertilizer.
  • a mixer means is mounted within the container means.
  • the mixing means is adapted to mix the quantity of organic fertilizer.
  • the mixer means may include a structure adapted for adding and blending, preferably to a homogeneous content, an acidic material and water into the quantity of organic matter sufficiently to render the pH of the resulting mixture acidic, and preferably strongly acidic.
  • the container means may also be fitted with a plurality of primary reservoirs.
  • Each of the primary reservoirs is adapted to contain a supply of a chemical composition selected from the following: phosphate, ammonium sulfate, potash, and humic acid.
  • Each primary reservoir is further adapted to supply a selected quantity of its respective chemical composition to the container means.
  • the container means may also be fitted with a plurality of secondary reservoirs.
  • Each of the secondary reservoirs is adapted to contain a chemical element selected from the following: copper, iron, magnesium, manganese and zinc.
  • Each of these secondary reservoirs is adapted to supply a selected quantity of the respective chemical element in the container means.
  • a grinding means may be associated with the container means for receiving organic matter, and processing that material to break up the mass of material into selected small masses.
  • a sterilizer means is associated with the container means.
  • the sterilizer means is adapted for introducing a quantity of a material having a base pH into the quantity of matter contained in the container means.
  • the sterilizer means is adapted to introduce this base material, e.g., anhydrous ammonium into the container means in sufficient quantities and with sufficient rapidity to quickly alter the pH of the resulting mixture from strongly acidic to slightly acidic or basic, i.e., a pH of 4.5 to 6.5.
  • the sterilizer means may include means of blending the contents of the container means so as to achieve a homogeneous mixture.
  • FIG. 1 shows a process diagram representation of the assimilation of materials in formatting the organic fertilizer wherein the sterilization of bacteria occurs in the reactor where anhydrous ammonia makes the mix nearly neutral or just slightly acidic after it's highly acidic treatment of sulfuric acid in the mixer.
  • the method and apparatus for sterilization of organic fertilizer includes the initial step of formulating components of the composite fertilizer including agglomeration.
  • the instant process may utilize various organic matters as the original organic material to form the principal constituent of the fertilizer. For example, steer manure, fish, refuse from garbage recycling centers, feed lot refuse, crops, waste from grapes, mint, apples, onions, sludge and solid waste from sewer treatment plants may all be utilized as the original organic matter. At this stage various chemical compounds may be added to the organic matter in order to supplement its nutrient content. It should be understood that the instant method can be adapted to produce fertilizers of various nutrient contents. Previous analysis of the soil to be treated provides the user with the means of determining the desired nutrient content of the fertilizer to be produced.
  • phosphate, ammonium sulfate, potash and humic acid may be added to the organic matter in order to yield a fertilizer having the proper nutrients to redress any inadequacies in the soil being treated.
  • the instant method also provides for the addition of various elements to the organic matter.
  • copper, iron, magnesium, manganese, and zinc may be added to the organic matter to rectify any deficiencies of these elements in the soil being treated.
  • the organic matter is thoroughly mixed with the desired chemical compounds and elements. The mixture at this point is largely dry in nature. The mixture is then treated with an acid, e.g., sulfuric acid. As the acid is added to the mixture, water is also added.
  • a sufficient quantity of acid is added to the mixture to yield a wet mixture having a pH which is acidic.
  • the wet mixture thus has a pH which is less than 5.
  • the mixture will have a pH of between about 4 and 5 on the standard pH scale.
  • the pH of the wet, slurry-like mixture is adapted by the addition of the sulphuric acid to be 4-5 on the pH scale. It should be recognized that the pH can be lowered below the preferred range.
  • the acid is thoroughly mixed with the dry mixture and water such that resulting wet mixture is uniformly acidic throughout.
  • the bacteria adapt to the acidic fertilizer environment within a short time after the addition of the acid, and thereafter thrive in the acidic environment.
  • the wet mixture is then further treated with a basic material, such as anhydrous ammonia NH3 in sufficient quantities to result in a sudden transition of the fertilizer pH from being strongly acidic to a mildly acidic or basic pH.
  • a basic material such as anhydrous ammonia NH3 in sufficient quantities to result in a sudden transition of the fertilizer pH from being strongly acidic to a mildly acidic or basic pH.
  • anhydrous ammonia is injected into the wet mixture by means of nozzles positioned within the bottom of the reactor vessel which contains the wet mixture.
  • the anhydrous ammonia in a liquid and gaseous form, is quickly introduced into and mixed within the wet mixture, preferably over approximately a one-minute interval.
  • the quantity of anhydrous ammonia which is introduced into the wet mixture is that quantity which is required to raise the pH of the wet mixture to approximately 6.5 or higher on the Ph scale.
  • the transition is of a sufficiently severe nature that the microbes, parasites, weed seeds and other life forms cannot survive the radical pH change. As a result, the bacteria, weed seeds, and other life forms die in seconds.
  • the finished organic fertilizer product is thus rendered sterile of bacteria which would otherwise thrive and consume the nitrogen. Since the bacteria have been eliminated, the fertilizer-held nitrogen and other ingredients are safely locked into the organic fertilizer, there being no viable life form remaining in the fertilizer which could oxidize the constituents of the fertilizer. Later, after the organic fertilizer is applied to the soil, the fertilizer is assumed by soil-borne bacteria. The bacteria assimilate the nitrogen, and alter it together with the other constituents of the fertilizer to make the constituents of the fertilizer assumable as nutrients by plants.
  • This invention produces organic fertilizer by a process wherein elimination of the bacteria in the fertilizer is accomplished during the production of the fertilizer itself by the use of chemicals which themselves are basic components of the fertilizer.
  • sulfuric acid and anhydrous ammonia utilized to sterilize the fertilizer, these chemicals actually form part of the nutrient components of the fertilizer.
  • Sterilization of the organic fertilizer product mix is done to kill bacteria in the product to prevent ingestion of the fertilizer's components by bacteria prior to the application of the fertilizer to the soil.
  • the elimination of the bacteria in the fertilizer precludes the consumption of the available nitrogen in the fertilizer prior to the fertilizer's application to the soil.

Abstract

Procédé et dispositif de stérilisation d'engrais organique, ledit procédé comprend l'étape consistant à formuler, dans les sections de mélange (1 et 2) d'ingrédients humides et secs, des constituants de l'engrais composite, après quoi lesdits constituants sont traités à l'aide d'un acide afin de former un mélange acide (c'est-à-dire d'un pH inférieur à 5) dans le réacteur de stérilisation (33). Les bactéries contenues dans le mélange s'adaptent en un temps court à l'environnement acide et elles y prolifèrent. Les constituants sont ensuite traités à l'aide d'une matière basique, telle que de l'ammoniaque anhydre, NH3 provenant d'un réservoir (38). La transition d'un pH fortement acide à modérément acide ou basique est d'une nature si brusque que les bactéries ne peuvent pas s'adapter au pH changé ainsi qu'à des changements de chaleur ce qui entraîne leur mort en l'espace de quelques secondes. Le produit d'engrais fini (51) est par conséquent rendu stérile du point de vue des bactéries, sans quoi ces dernières prolifèreraient et consommeraient l'azote renfermé par l'engrais. L'azote contenu dans l'engrais est ensuite renfermé de manière sûre dans l'engrais organique. L'azote est ensuite libéré lors de l'application au sol lorsque les bactéries se trouvant au niveau du sol s'alimentent à partir de l'engrais. Les bactéries consomment l'azote et elles modifient les constituants transformant les éléments en substances nutritives permettant la croissance de plantes.
