Carbon study shows CO₂ emission reductions up to 65 Kg/tonne of corn with Envita

Azotic technologies and Azotic North America’s nitrogen fixing technology will assist growers looking for ways to take advantage of carbon credits.  Envita™ in North America and N-Fix® in the rest of the world can significantly reduce carbon dioxide (CO2) emissions.

March 23, 2021: Raleigh, NC: A greenhouse gas impact study commissioned by Azotic North America indicates that significant carbon dioxide (CO2) emission reductions can be obtained through using Envita nitrogen fixing bacteria. In addition to providing increased yields to crops via N-Fixation, the study conducted by an independent third party, shows the use of Envita may qualify for significant carbon credits through its use.

The greenhouse gas impact study shows Envita N-fixing bacteria reduces carbon footprint in corn while increasing yields.

Here’s how Envita would return using $20 per metric tonne (or CO2e) per carbon credit.

An Envita-treated corn field producing a yield of 200 bushels per acre equals 5 tonnes of corn per acre.  At a CO2 reduction rate of 65 Kg per tonne of corn, this field would provide a reduction of 325 kg of CO2 per acre.  That’s 1/3 of a tonne of CO2 reduced per acre by using Envita. A US grower could receive $6.25/ac in carbon credits by using Envita.

“Sustainability in agriculture has quickly evolved from a topic of interest to a top priority,” explains Ray Chyc CEO of Azotic North America and Azotic Technologies, “These are early days in the monetisation of carbon in everyday farming, but it won’t be long before carbon is factored in with equal focus as seed, fertiliser and inputs.  Azotic North America is excited to see the carbon offsets that Envita can bring to crops like corn and is working with experts in the carbon markets to determine how to turn the Envita carbon credit story into real dollars in farmers pockets.”

Why does Envita have such a significant impact on the carbon footprint?

Envita N-fixing bacteria is applied in-furrow or as a foliar spray and enables cells throughout the entire plant to fix their own nitrogen. Envita naturally metabolizes N directly from the air, which is 78% nitrogen. The plant, drawing more N from the atmosphere, also pulls additional CO2 from the atmosphere as part of photosynthesis, which reduces the carbon footprint of that crop, leading to carbon credits.

Farmers using Envita to reduce applied nitrogen while maintaining yields increase their carbon credit potential even more. The combination of using less fertiliser and the process of pulling N from the atmosphere improves the crop’s carbon score.

Study shows Envita gives growers a choice

The greenhouse gas emissions (GHG) from producing most crops have three primary components, the emissions from on farm energy consumption, the emissions from the manufacturing of fertilisers, and the nitrous oxide (N2O) emissions associated with the decomposition of nitrogenous fertilisers and crops residues. The proportion of the three components varies with the crop and the producing region. The last component, the N2O emissions, is generally the largest of the three components for most crops. Growers earn credits for using the same rates of applied nitrogen with Envita or earn more with a reduction in applied nitrogen.

Azotic North America has undertaken field trials on a number of crops throughout North America. Azotic Technologies have undertaken similar work in Europe. The field trials suggest that Envita™/ N-Fix® could be employed with two different strategies:

  1. In one approach it would be used with normal fertilisation practices to achieve higher crop yields (Table ES-1)

  2. In the second approach, nitrogen fertiliser rates would be reduced but normal yields would be achieved with Envita™ supplying the plant with the remainder of its nitrogen requirements. (Tables ES-3).

About the Envita Carbon Study

The GHG emission calculations in the study follow the IPCC guidelines and use the regional N2O emission factors developed by Agriculture and AgriFood Canada. All of the carbon footprint standards and protocols outline specific inclusions and exclusions to be  included in the system boundaries. For this work they are: 1) The seeds, fertilisers and pesticides acquired and applied to the soil and plants, including the GHG emissions associated with the production, transportation and application of these crop inputs, 2) The fuel and energy consumed in the field work (tillage, seeding, fertilising, spraying, and harvesting activities) and the transportation of the product from the field to the on-farm storage bin. This includes the emissions associated with the production and use of the energy products, and, 3). The emissions from the decomposition of the applied fertiliser products and the crop residues that are left on the field after harvesting the grains and oilseeds. Changes in soil carbon resulting from changes in land management are excluded from this work. The high yield scenario should produce more biomass and potentially could lead to increased soil carbon, but this will be site dependent and dependent on the past and present tillage practices.
