Problems solved by technology

However, existing methods of processing poultry manure to produce biofertilizers have many disadvantages, including incomplete decomposition of organic matter and excessive foaming of bioreactor equipment
The latter results in a significant disruption of airflow and subsequent incomplete decomposition of organic matter, which often results in clogging of sprayers and other field application equipment with liquid fertilizer products, disrupting the operation of farming programs and increasing costs

Embodiment 1

[0142] Example 1. Method for producing fertilizer / nutritional composition from chicken manure

[0143] figure 1 Embodiments of the production methods described herein for the production of liquid and solid compositions from chicken manure are depicted in . figure 1 The production method depicted in produces a pathogen-free product that preserves the macro- and mesonutrients as well as micronutrients present in the manure of layer hens. In addition, the methods described herein remove potentially problematic phosphorus and hydrogen sulfide from the product.

[0144] Such as figure 1 As shown in , the process begins at 10 when raw chicken manure is transported directly from the farm to the site in a covered locker trailer. The trucks are unloaded into the mixing tank at said location and mixed with citric acid 15 and water to form a homogeneous slurry. Citric acid binds the natural organic ammonia in raw stool.

[0145]The next step in the method involves the preparation of...

Embodiment 2

[0167] Example 2. Bioreactor Kinetics During ATAB

[0168] The rate of organic matter decomposition during ATAB is adversely affected by increased foaming in the bioreactor, which interferes with oxygen supply. Insufficient oxygen supply to the liquid stream during ATAB makes less oxygen available and reduces the efficiency of organic matter decomposition. Oxidation-reduction potential (ORP) can be used to measure the efficiency of oxygen delivery resulting in increased oxidation of compounds in the liquid stream and decreased ORP value. Therefore, ORP can be used to measure the decomposition kinetics of organic matter in bioreactors.

[0169] To compare the ATAB kinetics of pure oxygen compared to atmospheric oxygen, a bioreactor delivered with pure oxygen was compared to, for example, ambient air. Five separate ATABs (see 3A-3E) for 80-90 hours were performed in a bioreactor equipped with 2 micron sintered stainless steel spargers injecting pure oxygen into the liquid stre...

Embodiment 3

[0174] Example 3. Bioreactor foam generation during ATAB

[0175] Foam levels generated during ATAB performed in bioreactors utilizing atmospheric oxygen delivery were compared to those generated in bioreactors using the pure or enriched oxygen delivery systems disclosed herein. The liquid fertilizer production method was performed on two different bioreactor oxygen delivery systems. In Process A, the production method was carried out as described in Example 1. Two bioreactors were used sequentially to promote the ATAB. Each bioreactor in Process A was equipped with 2 micron sintered stainless steel spargers that injected pure oxygen into the liquid stream at a rate of 1.0 CFM / 1,000 gallons. In Process B, each of the bioreactors was equipped with jet aeration to supply ambient air to the liquid stream. As shown in Table 8, delivery of pure oxygen significantly reduced foam levels in the bioreactor compared to ambient air delivery.

Abstract

The invention discloses a method for manufacturing compositions for plants and soils, such as liquid biofertilizers and solid biostimulants, from animal manure. The method includes the delivery of pure oxygen or oxygen-enriched air to a liquid fraction of animal manure and further include subjecting the liquid fraction to an autothermal thermophilic aerobic bioreaction. Nutritional compositions toenhance the effectiveness of synthetic fertilizers in conventional agriculture and / or for use in organic farming that are manufactured by these processes are also disclosed.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 713,325, filed August 1, 2018, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates generally to fertilizers and compositions useful for promoting plant growth and healthy soil structure. In particular, methods of making such fertilizers and compositions are disclosed. Background technique [0004] Two main categories of crop inputs are used in agriculture: fertilizers and pesticides. Fertilizer is generally described as any organic or inorganic material of natural or synthetic origin added to provide one or more nutrients necessary for plant growth. Fertilizers provide macronutrients, mesonutrients, and micronutrients in varying proportions that are required or beneficial to plant growth. [0005] Synthetic fertilizers and pesticides have been widely used in agriculture during the ...
