Embodiments of the invention provide a portable charcoal system and method of operating thereof, wherein the portable charcoal system comprises a first compartment adapted to burn a material, a second compartment connected to the first compartment and adapted to receive the material from the first compartment, and a third compartment adapted to receive the material from the second compartment, the third compartment comprising an auger adapted to move the material from a back end to a front end, and out of the third compartment. The portable charcoal system further includes a source of air.

A calcium carbonate agricultural product includes calcium carbonate. The calcium carbonate agricultural product may be used to replace any suitable agricultural plastic currently in use. A method of growing plants includes providing a calcium carbonate agricultural product including calcium carbonate to protect the plants. A method for controlling a pH of soil includes: providing a calcium carbonate agricultural product including calcium carbonate to the soil; and releasing the calcium carbonate of the calcium carbonate agricultural product to the soil.

According to some embodiments, there is provided herein a fertilizer granule comprising Polyhalite and Ammonium Sulphate, wherein said granule comprises a concentration of 40-60% w/w Polyhalite and 60-40% w/w of Ammonium Sulphate.

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.
