An automatic flushing device for a screen filter of a biogas slurry drip irrigation system and a use thereof are provided. The automatic flushing device includes a feeding mechanism, a filter unit, a discharging mechanism and a control mechanism, where the filter unit is provided with a feeding end fixedly threaded to a discharging end of the feeding mechanism and a discharging end fixedly threaded to a feeding end of the discharging mechanism; and the control mechanism is clamped on a pipe of the feeding mechanism. The automatic flushing device enhances the cleaning strength and uniformity of ultrasonic waves to the filter screen. The ultrasonic vibration rod is nested inside the upper filter casing through the externally-threaded hollow cap and a threaded top portion of the upper filter casing, which greatly facilitates the cleaning, replacement and maintenance of the ultrasonic vibration rod.

The invention is directed to organic fertilizers having commercial levels of nitrogen reacted with organic substances. The scalable process comprises adding an organic processing center to a fertilizer granulation plant specifically for the treatment of organics with an acid that acidifies, heats and liquifies a mix resulting in the hydrolysis of most or all organic material and polymers. For ammonium sulfate-based fertilizer this mix is only reacted with concentrated sulfuric acid. For ammonium phosphate fertilizers, this mix is reacted with both concentrated sulfuric acid and a concentrated phosphoric acid. The acidified organic mixes are piped to an existing or new granulation plant where it is injected with anhydrous ammonia in a tee mixer/reactor that results in a partially neutralized melt. Subsequently a sterilized and liquefied organic melt is sprayed over recycled bed material for production of granules before drying. Fertilizers made as disclosed provide a “green”, dual nitrogen-release profile when applied to crops releasing a bolus of nitrogen over one to two weeks following application followed by a slow or enhanced efficiency release of nitrogen over weeks of the growing season.

Disclosed are a method which provides microbial dissolution of organominerals such as organic wastes or chicken manure ashes burned in thermal power plants and return these ashes to the economy with the goal of zero waste with the created bio products and a system using this method.

The present disclosure relates to protein hydrolysate based biostimulant composition derived from methanotrophic bacteria, and methods for enhancing agricultural productivity.
