1. A process for reducing ammonia loss and odor from organic material or waste to the atmosphere, comprising feeding air or contaminated air to an electric arc, electrostatic field, Nano pulsed electric field, dielectric barrier discharged, laser, radio- or micro-wave driven plasma generator, or any combination thereof, to produce a concentration of 0.1-12% by volume of NOx in the air by direct nitrogen fixation and subsequent quenching to between 60° C. and 150° C. within 10−3 seconds;feeding the air containing NOx to an absorber, and absorbing the NOx into an absorption liquid in the absorber operating at a temperature between 20° C. and 80° C. to form an acidic nitrogen solution comprising nitrates and nitrites; andfeeding the acidic nitrogen solution to the organic material or waste whereby the pH is adjusted to 4-6 and the nitrates and nitrites bind volatile ammonia and ammonia components in or from the organic material or waste, as ammonium nitrate and nitrite salts. 2. The process according to claim 1, comprising feeding air or contaminated air to an electric arc, electrostatic field, Nano pulsed electric field, dielectric barrier discharged, laser, radio- or micro-wave driven plasma generator, or any combination thereof, to produce a concentration of 0.1-12% by volume of NOx in the air by direct nitrogen fixation and subsequent quenching to between 60° C. and 150° C. within 10−4 seconds; feeding the air containing NOx to an absorber after a retention time of 15 seconds to give a NO/NO2 mole ratio of 3, and absorbing the NOx into an absorption liquid in an absorber operating at a temperature between 30° C. and 60° C. to form an acidic nitrogen solution comprising nitrates and nitrites; and feeding the acidic nitrogen solution to the organic material or waste whereby the pH is adjusted to 4-6 and the nitrates and nitrites bind volatile ammonia and ammonia components in or from the organic material or waste, as ammonium nitrate and nitrite salts. 3. The process according to claim 1, wherein the acidic nitrogen solution is passed through a scrubber to absorb ammonia from ammonia contaminated ventilation air from the organic material or waste. 4. A process for reducing ammonia loss and odor from organic material or waste to the atmosphere, comprising feeding air or contaminated air to an electric arc, electrostatic field, Nano pulsed electric field, dielectric barrier discharged, laser, radio- or micro-wave driven plasma generator, or any combination thereof, to produce a concentration of 0.1-12% by volume of NOx in the air by direct nitrogen fixation and subsequent quenching to between 60° C. and 150° C. within 10−3 seconds;feeding the air containing NOx to an absorber, and absorbing the NOx into an absorption liquid in the absorber operating at a temperature between 20° C. and 80° C. to form an acidic nitrogen solution comprising nitrates and nitrites;using the acidic nitrogen solution in a scrubber to absorb ammonia from ammonia contaminated ventilation air from the organic material or waste and to produce an acidic ammonium nitrate and nitrite solution; andfeeding the acidic ammonium nitrate and nitrite solution produced in the scrubber to the organic material or waste. 5. The process according to claim 4, comprising feeding air or contaminated air to an electric arc, electrostatic field, Nano pulsed electric field, dielectric barrier discharged, laser, radio- or micro-wave driven plasma generator, or any combination thereof, to produce a concentration of 0.1-12% by volume of NOx in the air by direct nitrogen fixation and subsequent quenching to between 60° C. and 150° C. within 10−4 seconds; feeding the air containing NOx to an absorber, after a retention time of 15 seconds to give a NO/NO2 mole ratio of 3, and absorbing the NOx into an absorption liquid in an absorber operating at a temperature between 30° C. and 60° C. to form an acidic nitrogen solution comprising nitrates and nitrites; using the acidic nitrogen solution in a scrubber to absorb ammonia from ammonia contaminated ventilation air from the organic material or waste and to produce an acidic ammonium nitrate and nitrite solution; and feeding the acidic ammonium nitrate and nitrite solution produced in the scrubber to the organic material or waste. 6. The process according to claim 4, wherein the organic material or waste is treated in a bio gas reactor before feeding the acidic ammonium nitrate and nitrite solution produced in the scrubber to the organic material or waste. 7. The process according to claim 1, wherein air or contaminated air is fed to the plasma generator to produce a concentration of 2-12% by volume of NOx in the air by direct nitrogen fixation. 8. The process according to claim 1, wherein the absorption liquid is water or urine. 9. The process according to claim 1, wherein the absorption liquid is cold water in excess. 10. The process according to claim 1, wherein the organic material or waste is selected from livestock manure and biogas plant rest. 11. The process according to claim 1, wherein the nitrate and nitrite components are providing oxygen which suppresses the activity of sulfate reduction to H2S. 12. The process according to claim 1, wherein the nitrate and nitrite ratio in combination with a pH of 4-6 is used to disinfect organic materials or waste. 13. The process according to claim 1, wherein the molar ratio of nitrite to nitrate is kept between 1/10 and 1/100 which is inhibiting N2O being formed in the biological nitrification of ammonia. 14. The process according to claim 1, wherein the molar nitrate concentration is balancing the molar free ammonia-N concentration to improve the plant uptake rate of nitrogen. 15. The process according to claim 1, wherein the plasma generator is used to incinerate and disinfect contaminated air by exposing the contaminants to plasma and electron bombardment. 16. The process according to claim 1, wherein the nitrate and nitrite solution is used to improve the agronomic availability of the phosphate, through a temporary lowering of pH to 4 which is dissolving and mobilizing the colloidal phosphates precipitates. 17. The process according to claim 1, wherein the acidic nitrogen solution comprises: NO3− (nitrate),NO2− (nitrite) in a molar ratio NO2−/NO3− of 0.01-0.1,NH4+ in a molar ratio NH4+/NO3− of 0.02-0.50,NH2+ in a molar ratio NH2+/NO3− of 0.0001-0.05,other constituents in minor amounts.
