A digester system comprising a primary digester tank containing a primary feed material portion, a secondary digester tank containing a secondary feed material portion, a first conduit connected between the primary digester tank and the secondary digester tank to define a primary tank lower opening within the primary digester tank and a secondary digester tank lower opening within the secondary digester tank, and a flow control valve configured to allow or prevent flow of fluid through the first conduit. When the flow control valve is configured to allow flow of fluid through the first conduit, a portion of the primary feed material portion flows from the primary digester tank to the secondary digester tank to form the secondary feed material portion.

The present invention relates to a method of preparing a wood chip-type organic composite fertilizer wherein the method comprises the steps of: {circle around (a)} preparing wood chips by chipping; {circle around (b)} preparing a liquid organic fertilizer; {circle around (c)} forming an organic mixed solution; {circle around (d)} obtaining colored wood chips by simultaneously immersing the wood chips of the step {circle around (a)} in the organic mixed solution of the step {circle around (c)} and applying hot air to the organic mixed solution to coat the woods chips with colors; {circle around (e)} drying the wood chips to a high temperature to remove moisture formed on an outer surface of the wood chips of the step {circle around (d)} and to make the organic mixed solution penetrate evenly into the wood chips at the same time; and {circle around (f)} packing the dried wood chips of the step {circle around (e)} by weight unit with the measurement thereof on a scale.

Disclosed herein are microbial consortia and compositions including microbes, for example, for use in agricultural or biodegradation applications. In some embodiments, soil, plants, and/or plant parts (such as seeds, seedlings, shoots, roots, leaves, fruit, stems, or branches) are contacted with a disclosed microbial consortia or composition including microbes. The microbial consortia or microbe-containing compositions may be applied to soil, plant, and/or plant parts alone or in combination with additional components (such as chitin, chitosan, glucosamine, amino acids, and/or liquid fertilizer). In additional embodiments, the disclosed microbial consortia or compositions including microbes are used in methods of degrading biological materials, such as chitin-containing biological materials.

A composition of matter comprising a plant-usable nutrient derived from a first source, an odiferous compound obtained from a second source different from the first source; and a water-dissolvable carrier that carries the plant-usable nutrient and the odiferous compound.

A composition and process for improving the growth-promoting effectiveness of chitin-based fertilizers involves contacting the chitin-based material with a bacteria that secretes chitinase.

An agricultural energising biostimulating composition made from sucrose, protein/hydrolised protein, and humic acid. The composition is aimed at solving the energy deficit that is affecting the production of fruit and vegetables in the agriculture industry. Plants do not obtain the energy they need for their development, which affects the quality and quantity of the fruit produced.

The process for producing organic molecules from fermentable biomass includes a step of anaerobic fermentation (5) producing volatile fatty acids (6), these precursors being transformed into final organic molecules by non-fermentation means. It also includes at least the following steps: a) extracting (9) at least one portion of the volatile fatty acids from the fermentation medium in such a way that the production of fermentation metabolites by the microorganisms (M) is not affected, and introducing a portion of the liquid phase (11) containing microorganisms from the extraction (9), b) synthesizing (13) organic molecules from the fermentation metabolites or from the volatile fatty acids extracted in step a),-c) continuing steps a) to b) until the final molecules are obtained, in terms of amount and quality. The invention also relates to an installation for implementing the process.

A fertilizer composition and method to produced based on milk which comes from ruminant animals like cows and goats and adding a coal dust component. The previous or past milk-based fertilizers have had poor efficacy obtained due to the high fat content of these milk sources due to using too much milk, or rather too much fat in the milk, since the bacteria in the composition will spoil and result in a foul odor, poor growth, and poor crop yield. This fertilizer composition contains a nutrient ingredient, which is the de-fatted milk, as a liquid or dry product, and are utilized between 10 percent weight and 95 percent weight plus uses the coal dust as a less expensive stabilizer and chelator as well as other minerals for Nitrogen-Phosphorus-Potassium utilization.

A process to prepare an aqueous fertilizer with a high nitrogen content, said process comprising the steps of: providing a solid material having a high nitrogen content; providing a live yeast in solution adapted to enzymatically removing nitrogen-containing compounds from said solid; exposing said solid to said yeast in an aqueous environment, thereby creating a metabolically active culture mixture; incubating said metabolically active culture; injecting air in to the metabolically active mixture during said incubating step so as to inhibit the production of ethanol; wherein said metabolically active mixture undergoes said incubating step for a period of time sufficient to result in a nitrogen-fed yeast mixture; hydrolyzing (by autolysis) the resulting nitrogen-fed yeast mixture for a period of time sufficient to remove nitrogen from said yeast, where the nitrogen removed from said yeast is present in the mixture as dissolved nitrogen.
