Manure is an organic fertilizer with insufficient nitrogen content and low nitrogen use efficiency. The manure can be treated with acidic nitrate and nitrite during storage and before application. This will more than double its effective nitrogen content. The nutrient balance is improved and the spreading area better utilized.

Volatile ammonia is captured by nitrate and enriching the manure with nitrogen

Manure is a potential fertilizer containing all of the nutrients required for the plants.  The content of Nitrogen is however too low for a balanced fertilization for most crops.  During the storage and application of the manure, this disadvantage is further enhanced due to the loss of ammonia. The root of the problem is the biological decomposition which is releasing ammonia (NH3) and converting sulfates to hydrogen sulfide (H2S).

The best way to combat both the ammonia and the hydrogen sulfide is to acidify the manure with a mix of nitrate and nitrite.  The acidification is directly binding the ammonia and is providing oxygen which is suppressing the anaerobic conversion of sulfates to H2S.  The pH and the concentration NO2 are the parameters used to control the nitrification and de-nitrification processes.  In the production or preparation of the acidic nitrates, the content of HNO2is adjusted to give the right conditions for inhibition of the biological processes converting ammonia to N2  and N2O.

When the manure is acidified with nitrate, and applied as fertilizer, the growth response is direct and the N-use efficiency is improved.  For the plants the mix of nitrate-N and ammonium-N is giving an easier and just in time uptake.  Fusion farming is combing the efficiency of nitrate and technology with the organic resource at the fram to the best for the food production and environment.
