Disclosed herein are methods of increasing nitrogen fixation in a non-leguminous plant. The methods can comprise exposing the plant to a plurality of bacteria. Each member of the plurality comprises one or more genetic variations introduced into one or more genes or non-coding polynucleotides of the bacteria's nitrogen fixation or assimilation genetic regulatory network, such that the bacteria are capable of fixing atmospheric nitrogen in the presence of exogenous nitrogen. The bacteria are not intergeneric microorganisms. Additionally, the bacteria, in planta, produce 1% or more of the fixed nitrogen in the plant.

A method of producing a fertiliser composition, the method comprising: •(a) providing partially decomposed organic matter; •(b) contacting the organic matter with: •(i) an anaerobic digestate; •(ii) a source of nitrate ion; •(iii) a source of ammonia; and •(c) contacting the mixture obtained in step (b) with a source of carbon dioxide. •Also claimed is a fertiliser composition comprising partially decomposed organic matter admixed with an anaerobic digestate, a source of nitrate ion, a source of ammonia and carbon dioxide.

A microwave-plasma system for generating fixed-nitrogen products comprises a microwave generator operably coupled with a gas chamber where the microwave generator provides microwave power to the gas chamber. The system further includes a source of gas, which may be for example oxygen, nitrogen and/or air, operably coupled with the plasma chamber. The microwave power produces a plasma of the gas within the chamber. The system further includes an absorber unit fluidically connected to the gas chamber to capture product from the plasma in the gas chamber. The captured product may include fixed nitrogen gaseous products.

An improved method for treating ordinary tap water to create an enhanced water composition for watering plants which can remove fluoride and chlorides from the tap water, and finally, to treat the enhanced water composition to provide a preferred pH level that is ideal for growing plants, and particularly medically grown cannabis, in order to enhance the uptake of certain nutrients for these plants.

The present disclosure is drawn to anti-fungal pelleted blends, such as blends including multiple types of dry pellets homogenously admixed together. Pellets of the blend may include urea source pellets; ammonium source pellets including ammonium sulfate; phosphorus source pellets including an ammonium phosphate compound; and potassium source pellets including potassium chloride, potassium phosphate, potassium nitrate, potassium sulfate, or a combination thereof. The anti-fungal pelleted blend can be from 90 wt % to 100 wt % dissolvable in water at 20° C. within about 3 minutes. The multiple types of dry pellets may provide a total nitrogen content from 15 wt % to about 40 wt %, a total phosphorus content from about 1.8 wt % to about 8.8 wt %, and a total potassium content from about 4.1 wt % to about 16.6 wt %,

A method for using treated biochar to reduce the overall environmental impact of farming and minimize the carbon footprint of farms is provided. The method comprising engaging in one or more of the following practices: (1) combining treated biochar with feed or using biochar as feed for animals to reduce methane from enteric fermentation and increase animal health and nutrition; (2) combining treated biochar with compost, animal bedding or manure piles to reduce odor and increase nutrient retention; (3) applying treated biochar to lagoons to reduce odor and treat water; (4) applying treated biochar to pastures to increase pasture health; (5) applying treated biochar to crops to increase crop productivity, healthier roots and prevent fertilizer leaching; and (6) using the carbon negativity of a produced biochar to reduce the overall farm or ranch carbon footprint.

Aspects of the present disclosure involve a gliding-arc type plasma reactor for use in nitrogen-based fertilizer production. The plasma reactor may include a pair of electrodes oriented in a plane within an enclosure. A pair of sheaths may attach to a corresponding electrode, with each included a strike point surface oriented to face the other sheath. The electrodes may further include an inner channel through which a cooling fluid may be pumped for heat control. A gas injection system may also be included to inject a gas into the chamber for interacting with the plasma arc and may or may not include an adjustable nozzle. The nozzle may direct air flow, including the gas, at a location at which the plasma arc may occur. The device provides for a long lifetime of components within the device and easy replacement and maintenance of the components of high-wear items.
